One challenge is positioning the mouse cursor within confined target areas; another is executing a precise click without slipping. These problems can make mouse pointing in graphical user interfaces very difficult for some people. This article explores goal crossing as an alternative strategy for more accessible target acquisition. In goal crossing, targets are boundaries that are simply crossed by the mouse cursor. Thus, goal crossing avoids the two aforementioned problems. To date, however, researchers have not examined the feasibility of goal crossing for people with motor difficulties. We therefore present a study comparing area pointing and goal crossing. Our performance results indicate that although Fitts' throughput for able-bodied users is higher for area pointing than for goal crossing (4.72 vs. 3.61 bits/s), the opposite is true for users with motor impairments (2.34 vs. 2.88 bits/s). However, error rates are higher for goal crossing than for area pointing under a strict definition of crossing errors (6.23\% vs. 1.94\%). We also present path analyses and an examination of submovement velocity, acceleration, and jerk (the change in acceleration over time). These results show marked differences between crossing and pointing and almost categorically favor crossing. An important finding is that crossing reduces jerk for both participant groups, indicating more fluid, stable motion. To help realize the potential of goal crossing for computer access, we offer design concepts for crossing widgets that address the occlusion problem, which occurs when one crossing goal obscures another in persistent mouse-cursor interfaces. This work provides the motivation and initial steps for further exploration of goal crossing on the desktop, and may help researchers and designers to radically reshape user interfaces to provide accessible goal crossing, thereby lowering barriers to access.", acknowledgement = ack-nhfb, ajournal = "ACM Trans.

In this article, Glinert and York issued a ``call-to-arms'' for research and development on technologies for people with disabilities. Specifically, they highlighted that human-computer interfaces at the time generally failed to take into account the needs of disabled users. Their challenge was to change computing culture to address this need. Their article remains timely today in its consideration of government, industry, and private foundations working with researchers to achieve accessible technology. With the recent launch of {\em Transactions on Accessible Computing}, this seems an appropriate time to consider progress in the field since, as well as current research trends.\par The reprinting of this article is followed by four commentaries by leaders in accessibility research. Each was cited in the 1992 article and each now gives their view on how the field has progressed since that time. In their commentaries, some themes emerge and new technologies are discussed. In short, their commentaries point to both a great deal of progress and a lack of progress. All four of the commentators note areas where computing continues to present barriers rather than assist users with disabilities.\par Alistair Edwards sets the stage with a look back at interfaces and input technologies popular in 1992, with attention paid to access problems related to graphical user interfaces (GUIs) that have consumed much research energy since 1992. Alan Newell highlights disability concerns that were not given large research consideration in 1992, but which have now become significant due, in large part, to changes in global demographics. Specifically, he brings visibility to research on older adults and cognitively disabled users.\par A number of advances in technology and methodology since 1992 are discussed by the commentators. The ubiquity of computing and its critical adoption in the world today are highlighted. The commentators reflect, for example, on technologies produced by research for disabled users that have now impacted mainstream offerings on standards for accessibility that have emerged worldwide and their impact and on assistive technologies that have been developed. Critically, the proliferation of the World Wide Web was not foreseen in 1992 and its use by people with disabilities is discussed. Gregg Vanderheiden considers the opportunity afforded by the Web to provide widespread availability of accessible software.\par Glinert and York discussed the need for design for disability. While research relevant to users with disabilities is gaining momentum, the commentators indicate that users with disabilities still struggle with much of today's IT. The commentators note current trends toward designs that take into account disabled users. Notably, Richard Ladner ends his commentary by mentioning the issue of empowerment. Users with disabilities have moved beyond simply needing the protections of regulation that were emerging in 1992, to being active participants in designing solutions to allow full participation in the current social, political, and economic environments.\par Together, these articles provide a great deal of food for thought on technology advances and new considerations of accessible technology.

The World Wide Web as we know it had not yet been born. Today there are accessibility features built directly into every major operating system, and one OS even includes a built-in screen reader. Assistive technologies are more numerous and capable. And awareness of the importance of access is much higher. However, some things have not changed. Assistive technologies lag behind mainstream technologies in both compatibility and functionality. Effective assistive technologies are often beyond the financial reach of those who need them. Effective assistive technologies are not available in many countries and many languages, even though technology is reaching into education, employment, and daily living of more countries and more people in each country every year. In moving forward we need to build on what we have achieved and explore new concepts, such as a {\em common technical core, ubiquitous accessibility, micro-assistive technology}, and {\em free public accessibility}.

The main problem with these systems is that the communication process tends to be exceedingly slow, since the system must scan through the available choices one at a time until the desired message is reached. One way of raising the speed of message selection is to optimize the elementary scanning delay in real time so that it allows the user to make selections as quickly as possible without making too many errors. With this objective in mind, this article presents a method for optimizing the scanning delay, which is based on an analysis of the data recorded in ``log files'' while applying the EDiTH system [Digital Teleaction Environment for People with Disabilities]. This analysis makes it possible to develop a human-machine interaction model specific to the study, and then to establish an adaptive algorithm for the calculation of the scanning delay. The results obtained with imposed scenarios and then in ecological situations provides a confirmation that our algorithms are effective in dynamically adapting a scan speed. The main advantage offered by the procedure proposed is that it works on timing information alone and thus does not require any knowledge of the scanning device itself.

It has been questioned, however, whether such savings translate into an enhanced communication rate due to the additional overhead (e.g., shifting of focus and repeated scanning of a prediction list) required in using such a system. Our hypothesis is that word prediction has high potential for enhancing AAC communication rate, but the amount is dependent in a complex way on the accuracy of the predictions. Due to significant user interface variations in AAC systems and the potential bias of prior word prediction experience on existing devices, this hypothesis is difficult to verify. We present a study of two different word prediction methods compared against letter-by-letter entry at simulated AAC communication rates. We find that word prediction systems can in fact speed communication rate (an advanced system gave a 58.6\% improvement), and that a more accurate word prediction system can raise the communication rate higher than is explained by the additional accuracy of the system alone due to better utilization (93.6\% utilization for advanced versus 78.2\% for basic).", acknowledgement = ack-nhfb, ajournal = "ACM Trans.

In a previous baseline study, we examined the types of difficulties younger and older adults encounter when using pen-based input. The research reported in this article seeks to address one of these errors, namely, missing just below. This error occurs in a menu selection task when a user's selection pattern is downwardly shifted, such that the top edge of the menu item below the target is selected relatively often, while the corresponding top edge of the target itself is seldom selected. We developed two approaches for addressing missing just below errors: reassigning selections along the top edge and deactivating them. In a laboratory evaluation, only the deactivated edge approach showed promise overall. Further analysis of our data revealed that individual differences played a large role in our results and identified a new source of selection difficulty. Specifically, we observed two error-prone groups of users: the low hitters, who, like participants in the baseline study, made missing just below errors, and the high hitters, who, in contrast, had difficulty with errors on the item above. All but one of the older participants fell into one of these error-prone groups, reinforcing that older users do need better support for selecting menu items with a pen.

We present two alternative task completion strategies, based on differing input strategies (menu-based vs. free text entry). Empirical results from studies involving both blind and sighted users validate both the usability and accessibility of these differing strategies, with blind users achieving successful task completion rates above 90\%. The strengths of the alternate task completion strategies are discussed, along with possible approaches for improving the robustness of HIPUU.", acknowledgement = ack-nhfb, ajournal = "ACM Trans.

Non-traditional assistive technology is generally targeted for users with severe motor disabilities which may last long-term due to illness or injury or short-term due to situational disabilities. Control of a nontraditional assistive technology can vary widely across users depending upon many factors ranging from health to experience. Unfortunately, there is no systematic method for assessing usability of nontraditional assistive technologies to achieve the best control. The current methods to accommodate users through trial-and-error result in the loss of valuable time and resources as users sometimes have diminishing abilities or suffer from terminal illnesses.

One potential design approach to improve the learnability of mobile devices is a Multi-Layered (ML) interface, where novice users start with a reduced-functionality interface layer that only allows them to perform basic tasks, before progressing to a more complex interface layer when they are comfortable. We studied the effects of a ML interface on older adults' performance in learning tasks on a mobile device. We conducted a controlled experiment with 16 older (ages 65--81) and 16 younger participants (age 21--36), who performed tasks on either a 2-layer or a nonlayered (control) address book application, implemented on a commercial smart phone. We found that the ML interface's Reduced-Functionality layer, compared to the control's Full-Functionality layer, better helped users to master a set of basic tasks and to retain that ability 30 minutes later. When users transitioned from the Reduced-Functionality to the Full-Functionality interface layer, their performance on the previously learned tasks was negatively affected, but no negative impact was found on learning new, advanced tasks. Overall, the ML interface provided greater benefit for older participants than for younger participants in terms of task completion time during initial learning, perceived complexity, and preference.

This article describes the design and evaluation of a new calibration protocol for motion-capture gloves, which is designed to make the process more efficient and to be accessible for participants who are deaf and use American Sign Language (ASL). The protocol was evaluated experimentally; deaf ASL signers wore the gloves, were calibrated (using the new protocol and using a calibration routine provided by the glove manufacturer), and were asked to perform sequences of ASL handshapes. Five native ASL signers rated the correctness and understandability of the collected handshape data. In an additional evaluation, ASL signers were asked to perform ASL stories while wearing the gloves and a motion-capture bodysuit (in some cases our new calibration protocol was used, in other cases, the standard protocol). Later, twelve native ASL signers watched animations produced from this motion-capture data and answered comprehension questions about the stories. In both evaluation studies, the new protocol received significantly higher scores than the standard calibration. The protocol has been made freely available online, and it includes directions for the researcher, images and videos of how participants move their hands during the process, and directions for participants (as ASL videos and English text).", acknowledgement = ack-nhfb, ajournal = "ACM Trans.

Among these alternatives, grid-based navigation has demonstrated both potential and limitations. In this article, we discuss an empirical study that assessed the efficacy of two enhancements to grid-based navigation: magnification and fine-tuning. The magnification capability enlarges the selected region when it becomes sufficiently small, making it easier to see the target and cursor. The fine-tuning capability allows users to move the cursor short distances to position the cursor over the target. The study involved one group of participants with physical disabilities, an age-matched group of participants without disabilities, and a third group that included young adults without disabilities. The results confirm that both magnification and fine-tuning significantly improved the participants' performance when selecting targets, especially small targets. Providing either, or both, of the proposed enhancements substantially reduced the gaps in performance due to disability and age.

We wanted to investigate the likelihood that ``at least 80\% of knowledgeable human evaluators would agree on the conclusion'' of an accessibility audit, and therefore understand the percentage of success criteria that could be described as reliably human testable, and those that could not. In this case, we recruited twenty-five experienced evaluators to audit four pages for WCAG 2.0 conformance. These pages were chosen to differ in layout, complexity, and accessibility support, thereby creating a small but variable sample. We found that an 80\% agreement between experienced evaluators almost never occurred and that the average agreement was at the 70--75\% mark, while the error rate was around 29\%. Further, trained-but novice-evaluators performing the same audits exhibited the same agreement to that of our more experienced ones, but a reduction on validity of 6--13\% ; the validity that an untrained user would attain can only be a conjecture. Expertise appears to improve (by 19\%) the ability to avoid false positives. Finally, pooling the results of two independent experienced evaluators would be the best option, capturing at most 76\% of the true problems and producing only 24\% of false positives. Any other independent combination of audits would achieve worse results. This means that an 80\% target for agreement, when audits are conducted without communication between evaluators, is not attainable, even with experienced evaluators, when working on pages similar to the ones used in this experiment; that the error rate even for experienced evaluators is relatively high and further, that untrained accessibility auditors be they developers or quality testers from other domains, would do much worse than this.", acknowledgement = ack-nhfb, ajournal = "ACM Trans.

Recoloring tools have been developed to address the problem, but current recolorers are limited in that they work from a model of only one type of congenital CVD (i.e., dichromatism). This model does not adequately describe many other forms of CVD (e.g., more common congenital deficiencies such as anomalous trichromacy, acquired deficiencies such as cataracts or age-related yellowing of the lens, or temporary deficiencies such as wearing tinted glasses or working in bright sunlight), and so standard recolorers work poorly in many situations. In this article we describe an alternate approach that can address these limitations. The new approach, called Situation-Specific Modeling (SSM), constructs a model of a specific user's color differentiation abilities in a specific situation, and uses that model as the basis for recoloring digital presentations. As a result, SSM can inherently handle all types of CVD, whether congenital, acquired, or environmental. In this article we describe and evaluate several models that are based on the SSM approach. Our first model of individual color differentiation (called ICD-1) works in RGB color space, and a user study showed it to be accurate and robust (both for users with and without congenital CVD). However, three aspects of ICD-1 were identified as needing improvement: the calibration step needed to build the situation-specific model, and the prediction steps used in recoloring were too slow for real-world use; and the results of the model's predictions were too coarse for some uses. We therefore developed three further techniques: ICD-2 reduces the time needed to calibrate the model; ICD-3 reduces the time needed to make predictions with the model; and ICD-4 provides additional information about the degree of differentiability in a prediction. Our final result is a model of the user's color perception that handles any type of CVD, can be calibrated in two minutes, and can find replacement colors in near-real time ($^~$ 1 second for a 64-color image). The ICD models provide a tool that can greatly improve the perceptibility of digital color for many different types of CVD users, and also demonstrates situation-specific modeling as a new approach that can broaden the applicability of assistive technology.", acknowledgement = ack-nhfb, ajournal = "ACM Trans.

We then analyzed how these characteristics impact caption generation and readability, considering specifically our human-powered collaborative captioning approach.

To determine the effectiveness of existing text-based search for locating these SL videos, a series of queries were issued to YouTube to locate SL videos on the top 10 news stories of 2011 according to Yahoo!. Overall precision for the first page of results (up to 20 results) was 42\%. An approach for automatically detecting SL video is then presented. Five video features considered likely to be of value were developed using standard background modeling and face detection. The article compares the results of an SVM classifier when given all permutations of these five features. The results show that a measure of the symmetry of motion relative to the face position provided the best performance of any single feature. When tested against a challenging test collection that included many likely false positives, an SVM provided with all five features achieved 82\% precision and 90\% recall. In contrast, the text-based search (queries with the topic terms and ``ASL'' or ``sign language'') returned a significant portion of non-SL content---nearly half of all videos found.

To successfully perform ADLs, these people are reliant on the assistance of human caregivers. This leads to a decrease of independence for care recipients and imposes a high burden on caregivers. Assistive Technology for Cognition (ATC) aims to compensate for decreased cognitive functions. ATC systems provide automatic assistance in task execution by delivering appropriate prompts which enable the user to perform ADLs without any assistance of a human caregiver. This leads to an increase of the user's independence and to a relief of caregiver's burden. In this article, we describe the design, development and evaluation of a novel ATC system. The TEBRA (TEeth BRushing Assistance) system supports people with moderate cognitive disabilities in the execution of brushing teeth. A main requirement for the acceptance of ATC systems is context awareness: explicit feedback from the user is not necessary to provide appropriate assistance. Furthermore, an ATC system needs to handle spatial and temporal variance in the execution of behaviors such as different movement characteristics and different velocities. The TEBRA system handles spatial variance in a behavior recognition component based on a Bayesian network classifier. A dynamic timing model deals with temporal variance by adapting to different velocities of users during a trial. We evaluate a fully functioning prototype of the TEBRA system in a study with people with cognitive disabilities. The main aim of the study is to analyze the technical performance of the system and the user's behavior in the interaction with the system with regard to the main hypothesis: is the TEBRA system able to increase the user's independence in the execution of brushing teeth?", acknowledgement = ack-nhfb, ajournal = "ACM Trans.

Our main experiment is an analysis of speech from people with unilateral facial palsy. This pathology may impact the realization of certain phonemes such as bilabial plosives and sibilants. Speech read by 32 speakers at four different clinical severity grades was automatically aligned and GOP scores were computed for each phone realization. The highest scores, which indicate large dissimilarities with standard phone realizations, were obtained for the most severely impaired speakers. The corresponding speech subset was manually transcribed at phone level; 8.3\% of the phones differed from standard pronunciations extracted from our lexicon. The GOP technique allowed the detection of 70.2\% of mispronunciations with an equal rate of about 30\% of false rejections and false acceptances. Finally, to broaden the scope of the study, we explored the correlation between GOP values and speech comprehensibility scores on a second corpus, composed of sentences recorded by six people with speech impairments due to cancer surgery or neurological disorders.

However, it is the primary mechanism of communications for some speakers who have impaired voice production mechanisms, such as partial laryngectomees, as well as for those prescribed voice rest, which often follows surgery or damage to the larynx. Unlike most people, who choose when to whisper and when not to, these speakers may have little choice but to rely on whispers for much of their daily vocal interaction. Even though most speakers will whisper at times, and some speakers can only whisper, the majority of today's computational speech technology systems assume or require phonated speech. This article considers conversion of whispers into natural-sounding phonated speech as a noninvasive prosthetic aid for people with voice impairments who can only whisper. As a by-product, the technique is also useful for unimpaired speakers who choose to whisper. Speech reconstruction systems can be classified into those requiring training and those that do not. Among the latter, a recent parametric reconstruction framework is explored and then enhanced through a refined estimation of plausible pitch from weighted formant differences. The improved reconstruction framework, with proposed formant-derived artificial pitch modulation, is validated through subjective and objective comparison tests alongside state-of-the-art alternatives.", acknowledgement = ack-nhfb, ajournal = "ACM Trans.

We completed an empirical study to investigate the impact of different search methods and content structures on the search behavior of people with cognitive disabilities. 23 participants with various cognitive disabilities completed 15 information search tasks under three conditions: browsing a website with a deep structure ($ 4 \times 4 \times 4 \times 4$), browsing a website with a broad structure ($ 16 \times 16$), and searching through a search engine. The results suggest that the participants overwhelmingly preferred the search engine method to the two browsing conditions. The broad structure resulted in significantly higher failure rates than the search engine condition and the deep structure condition. The causes of failed search tasks were analyzed in detail. Participants frequently visited incorrect categories in both the deep structure and the broad structure conditions.

To refine and evaluate the techniques, we conducted three controlled laboratory studies. The first study, with 12 sighted participants, compared parameters for sonifying gestures in an eyes-free scenario. We identified pitch+stereo panning as the best combination. In the second study, ten blind and low-vision participants completed gesture replication tasks for single-stroke, multistroke, and multitouch gestures using the gesture sonification feedback. We found that multistroke gestures were more difficult to understand in sonification, but that playing each finger sound serially may improve understanding. In the third study, six blind and low-vision participants completed gesture replication tasks with both the sonification and corrective verbal feedback techniques. Subjective data and preliminary performance findings indicated that the techniques offer complementary advantages: although verbal feedback was preferred overall primarily due to the precision of its instructions, almost all participants appreciated the sonification for certain situations (e.g., to convey speed).

However, its sequential nature undermines both blind and sighted people's ability to efficiently find relevant information in the midst of several potentially useful items. We propose taking advantage of the Cocktail Party Effect, which states that people are able to focus on a single speech source among several conversations, but still identify relevant content in the background. Therefore, in contrast to one sequential speech channel, we hypothesize that people can leverage concurrent speech channels to quickly get the gist of digital information. In this article, we present an experiment with 46 (23 blind, 23 sighted) participants, which aims to understand people's ability to search for relevant content listening to two, three, or four concurrent speech channels. Our results suggest that both blind and sighted people are able to process concurrent speech in scanning scenarios. In particular, the use of two concurrent sources may be used both to identify and understand the content of the relevant sentence. Moreover, three sources may be used for most people depending on the task intelligibility demands and user characteristics. Contrasting with related work, the use of different voices did not affect the perception of concurrent speech but was highly preferred by participants.

This raises the possibility that what we call ``social accessibility'' may be as important as ``functional accessibility'' when considering ATs. But, to date, ATs have almost exclusively been regarded as functional aids. For example, ATs are defined by the Technical Assistance to the States Act as technologies that are ``used to increase, maintain or improve functional capabilities of individuals with disabilities.'' To investigate perceptions and self-perceptions of AT users, we conducted a diary study of two groups of participants: people with disabilities and people without disabilities. Our goal was to explore the types of interactions and perceptions that arise around AT use in social and public spaces. During our 4-week study, participants with sensory disabilities wrote about feeling either self-conscious or self-confident when using an assistive device in a social or public situation. Meanwhile, participants without disabilities were prompted to record their reactions and feelings whenever they saw ATs used in social or public situations. We found that AT form and function does influence social interactions by impacting self-efficacy and self-confidence. When the design of form or function is poor, or when inequality between technological accessibility exists, social inclusion is negatively affected, as are perceptions of ability. We contribute a definition for the ``social accessibility'' of ATs and subsequently offer Design for Social Accessibility (DSA) as a holistic design stance focused on balancing an AT user's sociotechnical identity with functional requirements.", acknowledgement = ack-nhfb, ajournal = "ACM Trans.

E-mail is the primary form of online communication for older adults. However, e-mail communication currently requires access to and the ability to use an Internet-connected computer or device, which may be problematic due to barriers of physical access, expense, insufficient computer skill, or other accessibility issues. To address this, the present work leverages the pervasive hardware of traditional phones and familiar nonvisual models of phone-based interaction to create a new e-mail interface for older adults. We examine the potential of e-mail interaction via traditional phones through long-term field observations, prototype testing, and a four-week field-based user study. Our findings indicate that a simple voice e-mail interface accessed through traditional phones is usable for older adults and is a useful way for offline older adults to interact with an e-mail account. The ease of use and convenience of a phone-based interface are important given the ``work'' of keeping in touch over e-mail, and this approach has the potential to open up new avenues of online access for older adults who are still offline or who have late-life disabilities that make using traditional graphical e-mail systems difficult.

Leveraging upon hidden Markov modeling techniques from ASR, we proposed a modeling framework for continuous SLR having the following major advantages, namely: (i) the system is easy to scale up to large-vocabulary SLR; (ii) modeling of signs as well as the transitions between signs is robust even for noisy data collected in real-world SLR; and (iii) extensions to training, decoding, and adaptation are directly applicable even with new deep learning algorithms. A pair of low-cost digital gloves affordable for the deaf and hard of hearing community is used to collect a collection of training and testing data for real-world SLR interaction applications. Evaluated on 1,024 testing sentences from five signers, a word accuracy rate of 87.4\% is achieved using a vocabulary of 510 words.

A finger-based approach, however, also introduces the need to guide the reader in physically navigating a document, such as tracing along lines of text. While previous work has proposed audio and haptic directional finger guidance for this purpose, user studies of finger-based reading have not provided an in-depth performance analysis of the finger-based reading process. To further investigate the effectiveness of finger-based sensing and feedback for reading printed text, we conducted a controlled laboratory experiment with 19 blind participants, comparing audio and haptic directional finger guidance within an iPad-based testbed. As a small follow-up, we asked four of those participants to return and provide feedback on a preliminary wearable prototype called HandSight. Findings from the controlled experiment show similar performance between haptic and audio directional guidance, although audio may offer an accuracy advantage for tracing lines of text. Subjective feedback also highlights trade-offs between the two types of guidance, such as the interference of audio guidance with speech output and the potential for desensitization to haptic guidance.

It compares three TVM designs regarding the usability criteria of effectiveness, efficiency and satisfaction, controlling for age, and cognitive and motivational characteristics. 62 older (M = 68 years) and 62 younger (M = 25 years) participants were split into three groups: The control group solved 11 tasks using a simulation of the TVM, the video group watched a brief instructional video before solving the same tasks with the same TVM, and the wizard group used a redesigned wizard interface instead. Results indicate that young and old participants' performance improved after watching the video, but older participants improved more, reaching the effectiveness of the young control group. In the wizard condition, age differences in effectiveness and satisfaction were eliminated; however, speed differences remained in all conditions. The results suggest that the simple integration of minimal video instruction or a task-oriented wizard design can make public access systems truly universally usable, and that the wizard TVM was a true ``walk-up-and-use system.''", acknowledgement = ack-nhfb, ajournal = "ACM Trans.

Using Invisible Puzzle, a mobile application which allows one to conduct non-supervised evaluation sessions, we conducted tests with 49 subjects with visual impairment and blindness, and 178 sighted subjects. All subjects involved in the process successfully completed the evaluation session, showing a high level of engagement, demonstrating, therefore, the effectiveness of the evaluation procedure. Results give interesting insights into the differences among the sonification techniques and, most importantly, show that after a short training, subjects are able to successfully identify several different shapes.", acknowledgement = ack-nhfb, ajournal = "ACM Trans.

It is known that deaf children benefit from early exposure to language, and higher levels of written language literacy have been measured in deaf adults who were raised in homes using ASL. In addition, prior work has established that new parents of deaf children benefit from technologies to support learning ASL. As part of a long-term project to design a tool to automatically analyze a video of a students' signing and provide immediate feedback about fluent and non-fluent aspects of their movements, we conducted a study to compare multiple methods of conveying feedback to ASL students, using videos of their signing. Through two user studies, with a Wizard-of-Oz design, we compared multiple types of feedback in regard to users' subjective judgments of system quality and the degree students' signing improved (as judged by an ASL instructor who analyzed recordings of students' signing before and after they viewed each type of feedback). The initial study revealed that displaying videos to students of their signing, augmented with feedback messages about their errors or correct ASL usage, yielded higher subjective scores and greater signing improvement. Students gave higher subjective scores to a version in which time-synchronized pop-up messages appeared overlaid on the student's video to indicate errors or correct ASL usage. In a subsequent study, we found that providing images of correct ASL face and hand movements when providing feedback yielded even higher subjective evaluation scores from ASL students using the system.", acknowledgement = ack-nhfb, ajournal = "ACM Trans.

By using capacitive markers, the coupling of the tactile graphics with the mobile device is simplified.

A prototypical implementation was tested by a user study with visually impaired people. All the participants were able to interact with the 3D printed tactile maps using a standard tablet computer.

The current work consisted of the design and feasibility testing of a novel gaze-sensitive social skills intervention system called MASI-VR. Adults from an outpatient clinic with confirmed SZ diagnosis ( n = 10) and a comparison sample of neurotypical participants ( n = 10) were evaluated on measures of emotion recognition and visual attention at baseline assessment, and a pilot test of the intervention system was evaluated on the SZ sample following five training sessions over three weeks. Consistent with the `enlrg' literature, participants in the SZ group demonstrated lower recognition of faces showing medium intensity fear, spent more time deliberating about presented emotions, and had fewer fixations in comparison to neurotypical peers. Furthermore, participants in the SZ group showed significant improvement in the recognition of fearful faces post-training.

However, in contrast to the patterns previously found with pen interaction, we found that miss error (i.e., both landing and lifting outside the target bounds) was a more common source of errors for older adults than slip error (i.e., landing on the target but slipping outside the target bounds before lifting). Moreover, aging influenced both miss and slip errors in our study of touch interaction, whereas for pen interaction, age has been found to influence only slip errors.

While there is a growing body of research regarding assessment of driving behavior or comparisons of driving behaviors between individuals with and without ASD, there is a lack of driving simulator that is catered toward the needs of individuals with ASD.

We believe that this simulator will provide opportunities for learning driving skills in a safe and individualized environment to individuals with ASD and help them with independent living. We also conducted a small user study with teenagers with ASD to demonstrate the feasibility and tolerability of such a driving simulator.

The results showed 94.8\%, 97.5\%, and 66.4\% of apps studied contained issues related to V, PV, or W, respectively. Five widget categories (TextView, ImageView, View, Button, and ImageButton) were used to create 92\% of the total number of the GUI elements and caused 89\%, 78\%, and 86\% of V, PV, and W, respectively. These accessibility issues were mainly caused by lack of element focus, missing element description, low text color contrast, lack of sufficient spacing between elements, and less than minimum sizes of text fonts and elements. Together, these accessibility issues accounted for 97.0\%, 77.8\%, and 94.5\% of V, PV, and W, respectively. This study proposed coverage measures to estimate the percentage of accessibility issues identified by an automated tool. The result showed that MAC, on average, identified about 67\% of accessibility issues in mobile apps. Two new accessibility conformance measures were proposed in this study: inaccessible element rate (IAER) and accessibility issue rate (AIR). IAER estimates the percentage of GUI elements that are inaccessible. AIR calculates the percentage of the actual number of accessibility issues relative to the maximum number of accessibility issues.

Another result is that community members frequently engage in a push-style delivery of content (e.g., emailing or posting links to videos for others in the sign language community) rather than having access be based on the information needs of community members. In prior work, we have shown the potential to detect sign language content using features derived from the video content rather than relying on metadata. Our prior technique was developed with a focus on accuracy of results and are quite computationally expensive, making it unrealistic to apply them on a corpus the size of YouTube or other large video sharing sites. Here, we describe and examine the performance of optimizations that reduce the cost of face detection and the length of video segments processed. We show that optimizations can reduce the computation time required by 96\%, while losing only 1\% in F1 score. Further, a keyframe-based approach is examined that removes the need to process continuous video. This approach achieves comparable recall but lower precision than the above techniques. Merging the advantages of the optimizations, we also present a staged classifier, where the keyframe approach is used to reduce the number of non-sign language videos fully processed.

Using off-the-shelf Bluetooth beacons installed in the surrounding environment and a commodity smartphone carried by the user, NavCog3 achieves unparalleled localization accuracy in real-world large-scale scenarios. By leveraging its accurate localization capabilities, NavCog3 guides the user through the environment and signals the presence of semantic features and points of interest in the vicinity (e.g., doorways, shops). To assess the capability of NavCog3 to promote independent mobility of individuals with visual impairments, we deployed and evaluated the system in two challenging real-world scenarios. The first scenario demonstrated the scalability of the system, which was permanently installed in a five-story shopping mall spanning three buildings and a public underground area. During the study, 10 participants traversed three fixed routes, and 43 participants traversed free-choice routes across the environment. The second scenario validated the system's usability in the wild in a hotel complex temporarily equipped with NavCog3 during a conference for individuals with visual impairments. In the hotel, almost 14.2h of system usage data were collected from 37 unique users who performed 280 travels across the environment, for a total of 30,200m traversed.", acknowledgement = ack-nhfb, ajournal = "ACM Trans.

Ally utilizes best practices from other areas of HCI research to create a more efficient and effective interaction for remediating regions, headers, reading order, and tables in a PDF document for improved accessibility. Twenty participants attempted to complete the same PDF accessibility remediation tasks using both Ally and a standard industry tool, Adobe Acrobat Pro. Ally was almost twice as fast and three times as accurate compared to Acrobat Pro, with participants reporting a strong preference for and a much higher level of satisfaction with Ally.

In this work, we sought to understand (1) the accessibility of current implementations of visualizations on the web; (2) BVI users' preferences and current experiences when accessing data-driven media; (3) how accessible data representations on the web address these users' access needs and help them navigate, interpret, and gain insights from the data; and (4) the practical challenges that limit BVI users' access and use of data representations. To answer these questions, we conducted a mixed-methods study consisting of an accessibility audit of 87 data visualizations on the web to identify accessibility issues, an online survey of 127 screen reader users to understand lived experiences and preferences, and a remote contextual inquiry with 12 of the survey respondents to observe how they navigate, interpret, and gain insights from accessible data representations. Our observations during this critical period of time provide an understanding of the widespread accessibility issues encountered across online data visualizations, the impact that data accessibility inequities have on the BVI community, the ways screen reader users sought access to data-driven information and made use of online visualizations to form insights, and the pressing need to make larger strides towards improving data literacy, building confidence, and enriching methods of access.

Equations in such documents consist of text interlaced with lines and other graphical elements and cannot be interpreted using a screen reader. We present a browsing approach for print-disabled readers specifically aimed at such mathematical content. This approach draws on the navigational mechanisms often used to explore the virtual worlds of text adventure games with audio-visual sensory substitution for graphical content. The relative spatial placement of the elements of an equation are represented as a virtual world so the reader can navigate between elements. Text elements are announced conventionally using synthesised speech, while graphical elements, such as roots and fraction lines, are rendered using a modification of the vOICe algorithm. The virtual world allows the reader to interactively discover the spatial structure of the equation, while the rendition of graphical elements as sound allows the shape and identity of elements that cannot be synthesised as speech to be discovered and recognised. The browsing approach was evaluated by 11 blind and 14 sighted participants in a user trial that included identifying twelve equations extracted from PDF documents. Overall, equations were identified completely correctly in 78\% of cases (74\% and 83\%, respectively, for blind and sighted subjects). If partial correctness is considered, then the performance is substantially higher. Feedback from the blind subjects indicated that the technique allows spatial information and graphical detail to be discovered. We conclude that the integration of a spatial model represented as a virtual world in conjunction with audio-visual sensory substitution for non-textual elements can be an effective way for blind and visually impaired readers to read currently inaccessible mathematical content in PDF documents.", acknowledgement = ack-nhfb, ajournal = "ACM Trans.

In our previous work (Campos et al. [6]), we propose a solution for automatic AD script generation, named CineAD, which uses the movie's script as a basis for the AD generation. This article proposes extending this solution to complement the information extracted from the script and reduce its dependency based on the classification of visual information from the video. To assess the viability of the proposed solution, we implemented a proof of concept of the solution and evaluated it with 11 blind users. The results showed that the solution could generate a more succinct and objective AD but with a similar users' level of understanding compared to our previous work.

This article aims to understand why blind users use these plugins, as well as how these plugins are developed, deployed, and maintained. To this end, we conducted an interview study with 14 blind users to gain individual perspectives and analyzed 2,000 online posts scraped from three plugin-related forums to gain the community perspective. Our study revealed that screen reader users rely on plugins for various reasons, such as to improve the usability of screen readers and application software, to make partially accessible applications accessible, and to receive custom auditory feedback. Furthermore, installing plugins is easy; uninstalling them is unlikely; and finding them online is ad hoc, challenging, and sometimes poses security threats. In addition, developing screen reader plugins is technically demanding; only a handful of people develop plugins. Unfortunately, most plugins do not receive updates once distributed and become obsolete. The lack of financial incentives plays in the slow growth of the plugin ecosystem. Further, we outlined the complex, tripartite collaboration among individual blind users, their online communities, and developer communities in creating a plugin. Additionally, we reported several phenomena within and between these communities that are likely to influence a plugin's development. Based on our findings, we recommend creating a community-driven repository for all plugins hosted on a peer-to-peer infrastructure, engaging third-party developers, and raising general awareness about the benefits and dangers of plugins. We believe our findings will inspire HCI researchers to embrace the plugin-based distribution model as an effective way to combat accessibility and usability problems in non-visual interaction and to investigate potential ways to improve the collaboration between blind users and developer communities.", acknowledgement = ack-nhfb, ajournal = "ACM Trans.
