Current dictionary tools require students to isolate a single sign they do not understand and input a search query, by selecting linguistic properties or by performing the sign into a webcam. Students may struggle with extracting and re-creating an unfamiliar sign, and they must leave the video-watching task to use an external dictionary tool. We investigate a technology that enables users, in the moment, i.e., while they are viewing a video, to select a span of one or more signs that they do not understand, to view dictionary results. We interviewed 14 American Sign Language (ASL) learners about their challenges in understanding ASL video and workarounds for unfamiliar vocabulary. We then conducted a comparative study and an in-depth analysis with 15 ASL learners to investigate the benefits of using video sub-spans for searching, and their interactions with a Wizard-of-Oz prototype during a video-comprehension task. Our findings revealed benefits of our tool in terms of quality of video translation produced and perceived workload to produce translations. Our in-depth analysis also revealed benefits of an integrated search tool and use of span-selection to constrain video play. These findings inform future designers of such systems, computer vision researchers working on the underlying sign matching technologies, and sign language educators.","PeriodicalId":384752,"journal":{"name":"Proceedings of the 24th International ACM SIGACCESS Conference on Computers and Accessibility","volume":"12 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122623994","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}

Thus, these technologies fulfil an important societal role and have a significant impact on the lives of those affected. This experience report provides insights on the lived experiences surrounding the necessary use of AT from the point of view of a disabled person. Using an autoethnographic approach, we determine the function and relevance of AT in everyday life and illustrate the intended and unintended effects of AT as well as the subsequently arising socio-technical dependencies through representative examples. The results show how the resulting dependencies on AT pose a risk for users, especially in the event of a technological failure. Furthermore, a deployment of AT without the necessary reflection and preparation of backup strategies in case of failure may lead to unexpected and inadvertent, potentially harmful, side-effects. Based on these observations, we elaborate on the implications for different stakeholder groups involved with the design, development, deployment and daily use of AT. We deem the key factors for success to lie in a deeper understanding of the application context, the integration of affected people in the development process as well as a fundamentally reflective approach by everyone involved with AT.","PeriodicalId":384752,"journal":{"name":"Proceedings of the 24th International ACM SIGACCESS Conference on Computers and Accessibility","volume":"182 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123079988","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}

But touches are not atomic—they unfold over time and space, especially for users with limited fine motor function, for whom it can be difficult to perform quick, accurate touches. To gain insight into what happens during a touch, we offer 15 target-agnostic touch metrics, most of which have not been mathematically formalized in the literature. They are touch direction, variability, drift, duration, extent, absolute/signed area change, area variability, area deviation, area extent, absolute/signed angle change, angle variability, angle deviation, and angle extent. These metrics regard a touch as a time series of ovals instead of a mere (x, y) coordinate. We provide mathematical definitions and visual depictions of our metrics, and consider policies for calculating our metrics when multiple fingers perform coincident touches. To exercise our metrics, we collected touch data from 27 participants, 15 of whom reported having limited fine motor function. Our results show that our metrics effectively characterize touch behaviors including fine-motor challenges. Our metrics can be useful for both understanding users and for evaluating touch-based systems to inform their design.","PeriodicalId":384752,"journal":{"name":"Proceedings of the 24th International ACM SIGACCESS Conference on Computers and Accessibility","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115423539","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}

While this approach is justifiable and contributes to the advancement of the field, many researchers argue that designing technologies for one impairment at a time contributes to an oversimplification of disability and does not reflect real-world experiences of a significant number of users who live with multiple impairments. How can the accessibility field leverage theories and concepts from other disciplines (e.g. disability studies, medical humanities, social work, engineering, education) to support more appropriate and inclusive technologies for users with complex needs? How can future assistive technologies take into consideration a diverse combination of sensory, cognitive, and physical characteristics? In this workshop, we invite researchers and practitioners from different disciplines to share their perspectives related to challenges and opportunities in designing accessible systems that consider the multidimensional and often complex needs of users living with multiple impairments.","PeriodicalId":384752,"journal":{"name":"Proceedings of the 24th International ACM SIGACCESS Conference on Computers and Accessibility","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123741447","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}
