While some prior research has explored its use as a reading assistance technology, including some empirical findings suggesting benefits for deploying this technology among particular groups of users, relatively little work has investigated the interest and requirements of specific groups of users of this technology. In this study, we investigated the interests of Deaf and Hard-of-Hearing (DHH) individuals in the computing industry in ATS-based reading assistance tools, motivated by prior work establishing that computing professionals often need to read about new technologies in order to stay current in their profession. Through a survey and follow-up interviews, we investigate these DHH individuals’ reading practices, current techniques for overcoming complicated text, and their interest in reading assistance tools for their work. Our results suggest that these users read relatively often, especially in support of their work, and they were interested in tools to assist them with complicated texts. This empirical contribution provides motivation for further research into ATS-based reading assistance tools for these users, prioritizing which reading activities users are most interested in seeing application of this technology, as well as some insights into design considerations for such tools.","PeriodicalId":433618,"journal":{"name":"Proceedings of the 22nd International ACM SIGACCESS Conference on Computers and Accessibility","volume":"259 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116220769","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 study, we propose a method for CI users to recognize precise pitch differences through tactile feedback. The proposed system encodes real-time audio signals to 36 musical tones (from C3 to B5), represented by tactile codes using nine vibration motors in a glove-type device. Two CI users participated in 15 h of training using our system and showed significant improvement in pitch accuracy while singing. In addition to the quantitative results, both participants expressed satisfaction in distinguishing and vocalizing musical tones, which led to increased interest in music. This study provides opportunities for CI users to engage more deeply and participate in musical education as well as achieve improved aural rehabilitation.","PeriodicalId":433618,"journal":{"name":"Proceedings of the 22nd International ACM SIGACCESS Conference on Computers and Accessibility","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116441194","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}

Adults with disabilities are three times more likely than adults without disabilities to have the serious underlying medical conditions which place them at a higher risk of severe illness from COVID-19. Dr. Lazar discusses two data collection efforts in the accessibility community to understand technology-related needs during the pandemic, and then highlights current initiatives to address these needs. Accessibility researchers and practitioners are currently working on projects that are 1) providing for accessible public health information and data (such as fully accessible data dashboards), 2) developing tools and technologies for helping people with disabilities stay healthy and avoid the virus (such as accessible masks and technologies for social distancing), and 3) ensuring that online learning and teleconferencing can be accessible for people with various disabilities and needs (such as Deaf users and users of AAC). Dr. Lazar challenges accessibility researchers and practitioners to get more involved in researching and developing digital technologies to improve the quality of life for people with disabilities. Specifically, he suggests some potential areas of research and development work: technologies to allow for priority scheduling of deliveries and purchasing of items with limited quantities for people with disabilities, new uses of crowdsourcing to empower people with disabilities during the pandemic, and studying the impact of masks on the use of automated speech recognition. Dr. Lazar ends the speech by challenging everyone to find accessibility projects that give you joy, are intellectually challenging, and meet the needs of the world!","PeriodicalId":433618,"journal":{"name":"Proceedings of the 22nd International ACM SIGACCESS Conference on Computers and Accessibility","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130963050","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 take a first step to design, detect, and evaluate a set of eyelid gestures for people with motor impairments on mobile devices. We present an algorithm to detect nine eyelid gestures on smartphones in real-time and evaluate it with twelve able-bodied people and four people with severe motor impairments in two studies. The results of the study with people with motor-impairments show that the algorithm can detect the gestures with .76 and .69 overall accuracy in user-dependent and user-independent evaluations. Moreover, we design and evaluate a gesture mapping scheme allowing for navigating mobile applications only using eyelid gestures.

However, some people have disabilities or circumstances that fall outside these pluralities, requiring a bespoke assistive technology to be developed and custom built to meet their unique requirements. To explore the opportunities and challenges of such an endeavor, we document the process undertaken to build a braille keyboard for a one-handed blind person over the course of 18-months. This process involved iterative prototyping within an intensive co-creation process, due to the unique needs arising from having two intersecting impairments and the challenges of effectively developing an entirely new format of AAT. Through a structured reflection on this process, we provide an account of the practical, pragmatic and ethical considerations that apply when developing a bespoke assistive technology, whilst illustrating the wider value of bespoke assistive technology development for a more general community of people with disabilities.","PeriodicalId":433618,"journal":{"name":"Proceedings of the 22nd International ACM SIGACCESS Conference on Computers and Accessibility","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126343942","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}

Consequently, investigators must adjust the methods employed throughout their studies to ensure the complex needs of people with ID are appropriately catered to. Yet, there are a lack of guidelines to support researchers in this process, with previous literature often neglecting to discuss the decisions made during the development of their study protocols. We propose a new procedure to overcome this lack of support, by utilizing the knowledge of “experts” in ID to design a more accessible workshop for the target population. 12 experts across two focus groups were successful in identifying accessibility barriers throughout a set of typical early co-design activities. Recommendations to overcome these barriers are discussed along with lessons on how to better support people with ID to engage in co-design.","PeriodicalId":433618,"journal":{"name":"Proceedings of the 22nd International ACM SIGACCESS Conference on Computers and Accessibility","volume":"38 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132638990","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, there is currently no direct feedback for blind users to check a constructed 3D mesh object for errors. This prevents a work pipeline independent from support by a sighted person. In this paper, we present a system that gives blind modelers an audio-haptic preview of their 3D object using an inexpensive haptic system with a single end effector. We first define a baseline approach that contains state-of-the-art features for an audio-haptic system, which we call ”free mode”. We then propose a novel guided mode that automatically moves the end effector along the contour of the orthographic projection of the model and improves the perception of the absolute position on the contour through audio clues. In a user study with total and near-total blind participants, the novel guided mode improves the users’ identification task by 34 percent compared to the baseline system. Furthermore, 3D models created with our full audio-haptic system contain significantly fewer mistakes and are rated on average 28 percent better than models created with the baseline system and 84 percent better than models without any audio-haptic preview.","PeriodicalId":433618,"journal":{"name":"Proceedings of the 22nd International ACM SIGACCESS Conference on Computers and Accessibility","volume":"125 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133746762","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}

Here, our intention was threefold. First, we wanted to engage in digital fabrication together with the therapists to ‘kick-off’ a co-design project and get to know them; the project was about creating therapeutic toys, and we hadn't met our participants or co-designers before. Second, we wanted to give them an impression of the tools we use and the sorts of designs that we are capable of producing in the course of such a one-year design project. Third, we aimed at generating a first set of design ideas. In this paper, we show in which ways teaching digital fabrication enabled us to accomplish these goals. Interestingly, we did not anticipate one of our most interesting findings. - As it turned out, the therapists continued creating their own designs after the project was completed, drawing on their newly developed digital fabrication skills. Hence, as a fourth outcome, we ‘accidently’ empowered the participants to address their problems independently.","PeriodicalId":433618,"journal":{"name":"Proceedings of the 22nd International ACM SIGACCESS Conference on Computers and Accessibility","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125486138","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}
