In an effort to understand how much sign language video quality can be sacrificed, we evaluated the perceived lower limits of intelligible sign language video transmitted at four low frame rates (1, 5, 10, and 15 frames per second [fps]) and four low fixed bitrates (15, 30, 60, and 120 kilobits per second [kbps]). We discovered an \"intelligibility ceiling effect,\" where increasing the frame rate above 10 fps decreased perceived intelligibility, and increasing the bitrate above 60 kbps produced diminishing returns. Additional findings suggest that relaxing the recommended international video transmission rate, 25 fps at 100 kbps or higher, would still provide intelligible content while considering network resources and bandwidth consumption. As part of this work, we developed the Human Signal Intelligibility Model, a new conceptual model useful for informing evaluations of video intelligibility.","PeriodicalId":378932,"journal":{"name":"Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133622165","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}

The most reliable approach to provide these captions is to recruit an expert stenographer who is able to type at natural speaking rates, but they charge more than $100 USD per hour and must be scheduled in advance. We introduce Legion Scribe (Scribe), a system that allows 3-5 ordinary people who can hear and type to jointly caption speech in real-time. Each person is unable to type at natural speaking rates, and so is asked only to type part of what they hear. Scribe automatically stitches all of the partial captions together to form a complete caption stream. We have shown that the accuracy of Scribe captions approaches that of a professional stenographer, while its latency and cost is dramatically lower.","PeriodicalId":378932,"journal":{"name":"Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124071286","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}

Video games have been shown to be an engaging leisure activity for older adults. In our work, we address the design of wheelchair-accessible motion-based games. We present KINECTWheels, a toolkit designed to integrate wheelchair movements into motion-based games, and Cupcake Heaven, a wheelchair-based video game designed for older adults using wheelchairs. Results of two studies show that KINECTWheels can be applied to make motion-based games wheelchair-accessible, and that wheelchair-based games engage older adults. Through the application of the wheelchair as an enabling technology in play, our work has the potential of encouraging older adults to develop a positive relationship with their wheelchair.","PeriodicalId":378932,"journal":{"name":"Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128765294","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}

Our lab has conducted prior evaluations of synthesized ASL animations: asking native signers to watch different versions of animations and answer comprehension and subjective questions about them. Seeking an alternative method of measuring users' reactions to animations, we are now investigating the use of eye tracking to understand how users perceive our stimuli. This study quantifies how the eye gaze of native signers varies when they view: videos of a human ASL signer or synthesized animations of ASL (of different levels of quality). We found that, when viewing videos, signers spend more time looking at the face and less frequently move their gaze between the face and body of the signer. We also found correlations between these two eye-tracking metrics and participants' responses to subjective evaluations of animation-quality. This paper provides methodological guidance for how to design user studies evaluating sign language animations that include eye tracking, and it suggests how certain eye-tracking metrics could be used as an alternative or complimentary form of measurement in evaluation studies of sign language animation.","PeriodicalId":378932,"journal":{"name":"Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129082811","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 describe one step toward supporting mobile users with SIIDs, through the design of tactile notifications. The tactile channel offers considerable promise to convey notifications to the user, freeing their visual and auditory channels for other tasks. A study was conducted to determine whether participants could develop tactile cues to convey the key characteristics of alerts to mobile users (e.g. urgency, relationship with the sender). The results highlight the benefits of tactile prototyping tools to encourage generation of design ideas, and the use of scenarios to situate these design ideas within the intended context of use.","PeriodicalId":378932,"journal":{"name":"Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121290638","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}

Focusing specifically on Irish Sign Language (ISL), we examine the Deaf community's appetite for sign language avatars. The work presented explores the following hypothesis: Augmenting an existing avatar with various combinations of the 7 widely accepted universal emotions identified by Ekman [1] to achieve underlying facial expressions, will make that avatar more human-like and consequently improve usability and understandability for the ISL user. Using human evaluation methods [2] we compare an augmented set of avatar utterances against a baseline set, focusing on two key areas: comprehension and naturalness of facial configuration. We outline our approach to the evaluation including our choice of ISL participants, interview environment and evaluation methodology.","PeriodicalId":378932,"journal":{"name":"Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122562047","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, most social networks are not designed with complete accessibility in mind. In particular, these networks' chronological organization of news items, abundant feature sets, and busy presentation can make these tools unusable to individuals with aphasia, an acquired language disorder that compromises an individual's ability to speak, write, and recognize language. This is unfortunate, as one of the primary means of managing aphasia is to keep individuals in community. To counter this, we have developed AphasiaWeb, a social network designed exclusively for keeping individuals with aphasia and their friends and families connected. In this paper we describe the social network and share findings from a two-month trial program conducted with a local aphasia support group.","PeriodicalId":378932,"journal":{"name":"Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131395626","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 order to mitigate this problem, we propose a multisensory platform called PlatMult, composed of visual, auditory, tactile feedback. The PlatMult provides a screen magnifier, integrated with a screen reader, and an adapted mouse with motor feedback. The feedback is fired in an integrated way; for instance, when the user moves the mouse over links and buttons in a webpage, the PlatMult activates the screen reader and the mouse motor feedback.
