Decreasing stress during the interview has been shown to improve interview performance. However, in order to effectively provide insights on stress to both interviewees and interviewers, it is necessary to first effectively measure stress. This work explores physiological stress detection through wearable sensing as a means of obtaining quantitative stress measures from young autistic adults undergoing a virtual simulated interview using supervised machine learning techniques. Several supervised learning models were explored and it was found that Elastic Net Regression had the best accuracy with individual models with an accuracy of 84.8% while Support Vector Regression models evaluated with leave-one-out cross validation had a group accuracy of 75.4%. The predictions from the stress model were used with data visualization techniques in order to provide insights on the interview process from both a group and individual viewpoint, showing that stress trends can be found and evaluated using the stress model. This work also addresses a major gap in physiological stress detection literature by presenting a novel dataset of physiological data and ground truth labels for 15 autistic young adults undergoing a simulated interview.","PeriodicalId":54128,"journal":{"name":"ACM Transactions on Accessible Computing","volume":"17 21","pages":""},"PeriodicalIF":2.4,"publicationDate":"2024-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139445378","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}

Significant developments in artificial intelligence (AI) mean that Automatic Speech Recognition (ASR) is now a part of many popular applications. This makes creating captions easy and broadly available - but transcription needs high levels of accuracy to be accessible. Scientific publications and industry report very low error rates, claiming AI has reached human parity or even outperforms manual transcription. At the same time the DHH community reports serious issues with the accuracy and reliability of ASR. There seems to be a mismatch between technical innovations and the real-life experience for people who depend on transcription. Independent and comprehensive data is needed to capture the state of ASR. We measured the performance of eleven common ASR services with recordings of Higher Education lectures. We evaluated the influence of technical conditions like streaming, the use of vocabularies, and differences between languages. Our results show that accuracy ranges widely between vendors and for the individual audio samples. We also measured a significant lower quality for streaming ASR, which is used for live events. Our study shows that despite the recent improvements of ASR, common services lack reliability in accuracy.","PeriodicalId":54128,"journal":{"name":"ACM Transactions on Accessible Computing","volume":"5 8","pages":""},"PeriodicalIF":2.4,"publicationDate":"2023-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138586365","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}

{"title":"Helping or hindering: Inclusive Design of Automated Task Prompting for Workers with Cognitive Disabilities","authors":"Gavin R. Philips, Morris Huang, Cathy Bodine","doi":"10.1145/3628447","DOIUrl":"https://doi.org/10.1145/3628447","url":null,"abstract":"Of the ∼8.8 million working-age adults with cognitive disabilities in the United States, only 28.6% are employed, contributing to a poverty rate (26.1%) for people with cognitive disabilities (PwCDs) that is more than twice that for people without disabilities. PwCDs who are employed are often still marginalized via reduced hours and pay, largely due to their more limited capability to perform work efficiently and independently. As evidence, warehouse and shelf stocking jobs that serve as employment for a significant percentage of PwCDs, often require frequent intervention from a job coach in the workplace, impacting the pay and self-esteem of these workers. This study's objective was to remove barriers to employment for PwCD through inclusive design of technology supports in warehouse and similar settings. Specifically, a nonlinear context-aware prompting system (NCAPS) was developed, iteratively refined, and tested. In a pilot crossover study, subjects with cognitive disabilities participated in simulated work sessions, picking orders in a small warehouse environment using the NCAPS and industry standard paper tickets. Their performance was assessed in terms of errors and productivity, and their insights and perspectives were gathered. The resulting NCAPS prevented or corrected all errors for all but one participant. It also increased productivity for participants with the poorest baseline (paper ticket) performance, but decreased productivity for those with high baseline performance. No significant difference was observed in system usability scale (SUS) scores between methods. Topics emerging from user input highlighted the need for technological supports for PwCD to be simple and flexible in operation, and reliable to maintain user trust. By prioritizing robustness and intuitiveness, flexible technology supports can be developed to empower workers with a broad range of abilities, including those with temporary and situational impairments. Such tools would reduce barriers to employment, including stigma, discrimination, and other barriers to equity.","PeriodicalId":54128,"journal":{"name":"ACM Transactions on Accessible Computing","volume":"143 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2023-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139311962","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}

Recently, researchers have started to explore the possibilities and challenges of using DIY-ATs in contexts other than the Global North, where access to digital ATs is limited. Previous research has not yet studied the perspectives of caregivers of children with disabilities towards these technologies. We present findings from an interview study with caregivers of children and youth with cognitive disabilities in Western Kenya who used a DIY-AT system as a research probe. Participants described how negative beliefs about people with disabilities result in social exclusion and discrimination and explained how increased opportunities for social interaction and learning mediated through DIY and other customizable ATs for their children could support their inclusion, safety, and access to future opportunities.","PeriodicalId":54128,"journal":{"name":"ACM Transactions on Accessible Computing","volume":"47 1","pages":"1 - 27"},"PeriodicalIF":2.4,"publicationDate":"2023-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87838029","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, current music education research focuses primarily on app-based DMIs. Although these devices have numerous advantages, such as ubiquitous availability and flexibility, they may be experienced as disabling by people with severe cognitive or complex disabilities. Thus, they only partially exploit the potential of DMIs for special educational needs (SEN) music practices, which we outline in this article. However, given that no comprehensive studies have yet been conducted on the use of DMIs in SEN schools, the actual motives and barriers for SEN school teachers to employ different types of DMIs in class are largely unknown. To address this research gap, we present the results of a quantitative survey covering all SEN schools in 12 of Germany's 16 federal states. We surveyed the status quo of DMI use in SEN schools and the perceived potential of DMIs and DMI-related information needs from the music teachers’ perspective. Our findings demonstrate that DMIs are only rarely used in Germany, with the exception of established standard DMIs such as keyboards and music apps. Unfortunately, accessible DMIs (ADMIs) are hardly used. Related to the rare use of DMIs in SEN schools, we also identified a lack of domain-specific knowledge among music teachers and concluded that there was a need to develop DMIs specifically designed for use in classroom education. Finally, we discuss the potential of using open-source DMI technology as well as the importance of identifying music teachers’ attitudes during DMI development.","PeriodicalId":54128,"journal":{"name":"ACM Transactions on Accessible Computing","volume":"41 1","pages":"1 - 34"},"PeriodicalIF":2.4,"publicationDate":"2023-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79248062","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, BLV music learners face complex obstacles in learning music. They are highly reliant on their learning environment and music teachers for accommodations and flexibility. Prior research identified the challenges faced by BLV musicians. Yet, limited research has addressed these challenges through the development of technology. Drawing upon the experience and suggestions of 40 BLV professional musicians, amateur musicians and music teachers (including sighted teachers with experience teaching blind students), we identified five themes: (1) Key Challenges of BLV Music Learning, (2) Personal Adaptations to Overcome Music Learning Challenges, (3) Perspectives on Current and Future Assistive Technologies, (4) Contention Between Braille Music and Auditory Learning, and (5) Role of Human Support for Music Learning. Together, these findings outline a path to make music learning more accessible to BLV people. To this end, we describe opportunities for enhanced audio cues for musical communication, recommend integrating vibrotactile feedback to aid music reading and design technology that supports independence and interdependence in music learning.","PeriodicalId":54128,"journal":{"name":"ACM Transactions on Accessible Computing","volume":"7 1","pages":"1 - 20"},"PeriodicalIF":2.4,"publicationDate":"2023-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91172080","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 our work, we present findings from a study (N = 44) in which we combined semi-structured interviews and an online survey to explore different approaches towards visualizing PA data for older adults. Through thematic analysis and statistical analysis, we highlight that visualizations’ perceived usefulness and appeal is individual and mediated by the lived experiences of late life, and that the potential of performance and pleasure can be leveraged to be complementary. On this basis, we discuss design opportunities for visualizations of PA data specifically addressing the needs of older adults from the perspective of PA in late life.","PeriodicalId":54128,"journal":{"name":"ACM Transactions on Accessible Computing","volume":"1 1","pages":"1 - 35"},"PeriodicalIF":2.4,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80315879","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}

Increasingly, research has sought to address these shortcomings with recommendations for design. However, commercial uptake of these findings remains limited, in part, due to the scattering of recommendations across publications, heterogeneity in the SNS systems and features examined, and a lack of sensitivity within the existing guidelines to the heterogeneity of the target demographic. To counter these challenges, we conducted a systematic review following a thematic synthesis approach of 25 empirical studies on SNS design recommendations for older adults. From these, we synthesized a cohesive set of ten distinct design recommendations. These include ensuring an easy-to-use interface, improving social connection features, ensuring personal privacy, and introducing customized features and personalized content. In synthesizing the results, particular care was taken to capture the ways in which population diversity moderates recommendations. The results of this review can serve as a resource for designers and practitioners working on inclusive SNS for older adults. They also highlight the need for additional research into understanding user diversity in relation to SNS accessibility.","PeriodicalId":54128,"journal":{"name":"ACM Transactions on Accessible Computing","volume":"29 1","pages":"1 - 23"},"PeriodicalIF":2.4,"publicationDate":"2023-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88919371","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}
