However, using this technology can lead to security and privacy concerns, including the possibility of disclosing a disability. In this work, we explore that and other privacy risks happening through the use of assistive technology in educational settings. We conducted interviews with eight students who use assistive technology, exploring the risks around in-person and online classes and how they changed as students moved to remote courses during the COVID-19 pandemic. We found that students were aware of in-person risks, but generally had not thought of the potential risks of online disclosure. Students were concerned about their disability being disclosed, especially without their explicit consent, but they considered trade-offs, including increased accessibility for themselves and others, that might make them more accepting of disclosure. Building on the interviews, we did an analysis of the privacy policies of the assistive technology that the students used, examining how potential privacy and security vulnerabilities were communicated. We found that, although there are identified vulnerabilities for many of the assistive technologies, the policies varied widely in whether or how much information they gave the user about the risks.","PeriodicalId":54128,"journal":{"name":"ACM Transactions on Accessible Computing","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141384623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, many projects aiming to support such accessibility needs come and go, or never make it to a public release. To reduce the overhead involved in deploying and maintaining a system that transforms web content into multimodal renderings, we created an open-source, modular microservices architecture as part of the IMAGE project. This project aims to design richer means of interacting with web graphics than is afforded by a screen reader and text descriptions alone. To benefit the community of accessibility software developers, we discuss this architecture and explain how it provides support for several multimodal processing pipelines. Beyond illustrating the initial use case that motivated this effort, we further describe two use cases outside the scope of our project in order to explain how a team could use the architecture to develop and deploy accessible solutions for their own work. We then discuss our team’s experience working with the IMAGE architecture, informed by discussions with six project members, and provide recommendations to other practitioners considering applying the framework to their own accessibility projects.","PeriodicalId":54128,"journal":{"name":"ACM Transactions on Accessible Computing","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141104519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we present a framework called\u0000 Accessible image-Association-based Authentication for Computing-devices (A3C)\u0000 , a novel recognition-based graphical authentication framework specifically designed for people with UEI to authenticate to their computing devices. A3C requires users to provide a set of primary images that the user knows that are recognizable to them and subsequently associate each primary image with a secondary image. To evaluate the efficacy of the A3C framework, we instantiated the framework by implementing a version of A3C called\u0000 A3C-FA\u0000 , which uses images of faces of people the user knows as the primary image and animal images as the secondary image. We then performed three studies to evaluate A3C-FA: a shoulder-surfing attack study (\u0000 N=319\u0000 ), a close-adversary attack study (\u0000 N=268\u0000 ), and a usability study with people with UEI (\u0000 N=14\u0000 ). We found that A3C was robust against both shoulder-surfing and close-adversary attacks. We also performed a detailed study to evaluate the accessibility of A3C-FA. Our participants reported that A3C-FA was more usable and more secure than the authentication approaches with which they were familiar. Based on these findings, we suggest four areas of future research to further improve the design of A3C framework.\u0000","PeriodicalId":54128,"journal":{"name":"ACM Transactions on Accessible Computing","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140229507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We adopt a socio-cultural lens to examine how the context of education and training influences teaching and learning in university and workplace sectors, and how expert educators manage and negotiate these contextual factors to build accessibility capacity. This paper reports qualitative research with 55 experienced educators using expert panel method and focus groups. Analysis highlights the important disconnects and contextual challenges that educators must navigate and negotiate to affect and embed cultural change. We find that faculty and workplace cultures frequently perpetuate precarity in accessibility education, individualising the responsibility to ‘heroes’ or ‘champions’, while disciplinary and role-based silos limit the scope for raising awareness and developing widescale competency. Conversely, centres of excellence and communities of practice can cultivate and sustain links between education and research, engage expert users, and promote interdisciplinary and cross-role learning environments, where accessibility is increasingly recognised as a shared endeavour. We conclude that greater collaboration between academia and industry can enhance pedagogical understanding, to transform accessibility educational practices and build and sustain capacity for the future.","PeriodicalId":54128,"journal":{"name":"ACM Transactions on Accessible Computing","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140248337","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, when such navigation aids are unavailable or not appropriately marked up, this situation can cause serious difficulties. This paper presents the design and evaluation of a tool for automatically generating navigation aids with headers and internal links for screen readers with topicalisation and labelling algorithms. The proposed tool uses natural language processing techniques to divide a web document into topic segments and label each segment in two cycles based on its content. We conducted an initial user study in the first cycle with eight blind and partially-sighted screen reader users. The evaluation involved tasks with questions answered by participants with information from texts with and without automatically generated headers. The results in the first cycle provided preliminary indicators of performance improvement and cognitive load reduction. The second cycle involved co-designing an improved version with two blind experts in web accessibility, resulting in a browser extension which injects automatically generated headers and in-page navigation with internal links, along with improvements in the generation of labels using OpenAI’s ChatGPT. The browser extension was evaluated by seven blind participants using the same four texts used to evaluate the preliminary prototype developed in the first cycle. With the two development cycles, the study provided important insights into the design of navigation aids for screen-reader users using natural language processing techniques, including the potential use of generative artificial intelligence for assistive technologies and limitations that need to be explored in future research.","PeriodicalId":54128,"journal":{"name":"ACM Transactions on Accessible Computing","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140421375","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Parkinson's Disease (PD) is a common neurodegenerative disease that affects millions of people worldwide. PD presents a broad range of motor and non-motor symptoms that are unique to each person with PD, thus requiring unique intervention needs for people with PD. Self-tracking can aid treatment for people with PD, by recording their experiences and responses to intervention. We conducted semi-structured interviews with 26 people with PD (PwPD), 6 caregivers (CGs), and 3 healthcare providers (HPs) to acquire a better understanding of their experiences with the strategies and challenges of self-tracking. Five tracking strategies were identified: mental tracking, analog tracking, tracking with general-purpose technology, specialized technology tracking, and tracking by proxy. We also uncovered challenges experienced during self-tracking, such as symptoms not always distinctive or easy to describe, inaccuracy of tracking, lack of perceived usefulness of tracked data, interaction barriers with technology, and lack of proper tracking tools. Our findings contribute to existing literature and yield insights to guide the inclusive design of self-tracking tools for PD.","PeriodicalId":54128,"journal":{"name":"ACM Transactions on Accessible Computing","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140427815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditionally, AT has successfully addressed core functional needs, such as enabling cursor movement and clicking actions with devices like computer mice. However, a comprehensive approach to AT design also necessitates a thorough consideration of sensory feedback, including tactile sensations, ergonomics, and auditory cues like button click sounds. These aspects are not merely supplementary but are integral to the device’s functionality, enhancing user interaction and long-term comfort, especially for individuals with motor impairments. In this work, we present MouseClicker, a mechatronic AT to surrogate physical agency over a computer mouse and to foster the haptic sensory experience of clicking on it tailored specifically for an individual with Spinal Muscular Atrophy (SMA) who faces challenges in using a standard mouse due to severe hand motor impairments. Our design aims to replicate the holistic experience of clicking a mouse, from its functional mechanical actions to its nuanced tactile and auditory feedback. This work details the MouseClicker’s design and reports on an exploratory user study aimed at identifying optimal vibrotactile feedback parameters — such as location, and intensity — that represent mouse button clicks. MouseClicker presents a step forward in AT design by integrating the functionality, sensory feedback, and the overall experience of taking control over non-AT devices.","PeriodicalId":54128,"journal":{"name":"ACM Transactions on Accessible Computing","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139958898","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
