Originally developed by (and for!) the first author, the tool replaces the standard input devices -- i.e., keyboard and mouse -- with a small numerical keypad, making optimal use of his abilities. The paper attempts to illustrate some of the difficulties the first author usually has to face when operating a computer, due to considerable motor problems. It will be shown what he tried in the past, and why OnScreenDualScribe, offering various assistive techniques -- including word prediction, an ambiguous keyboard, and stepwise pointing operations -- is indeed a viable alternative. The ultimate goal is to help not only one single person, but to make the system -- which does not accelerate entry very much, but clearly reduces the required effort -- available to anyone with similar conditions.","PeriodicalId":378932,"journal":{"name":"Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility","volume":"135 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":"121340070","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 system uses a client-server architecture model and facilitates task-oriented remote therapeutic training in both in-home and clinical settings. Namely, the system allows a speech therapist to remotely assign speech production exercises to each child through a web interface, and the child to practice these exercises on a mobile device. The mobile app records the child's utterances and streams them to a back-end server for automated scoring by a speech-analysis engine. The therapist can then review the individual recordings and the automated scores through a web interface, provide feedback to the child, and adapt the training program as needed. We validated the system through a pilot study with children diagnosed with apraxia of speech, and their parents and speech therapists. Here we describe the overall client-server architecture, middleware tools used to build the system, the speech-analysis tools for automatic scoring of recorded utterances, and results from the pilot study. Our results support the feasibility of the system as a complement to traditional face-to-face therapy through the use of mobile tools and automated speech analysis algorithms.","PeriodicalId":378932,"journal":{"name":"Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility","volume":"31 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":"127626702","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 much prior research has explored the effects of motor impairments on accessing computer input devices, such as keyboards, mice, and touch screens, we know relatively little about how real world use of a wheelchair affects why people in power wheelchairs choose specific computing devices, and how they switch between such devices. We interviewed 8 power wheelchair users about their use of computers and mobile devices. We found that participants often had difficulty switching between the various devices in their life, and that technology use was especially challenging on the go. Our findings suggest that there are numerous opportunities to make computing more wheelchair-friendly, by consolidating devices, improving reachability and portability of devices, and by creating technology that is robust to the challenges of moving around in a wheelchair.","PeriodicalId":378932,"journal":{"name":"Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility","volume":"18 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":"133420457","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}

This problem worsens when indexes lack information scent: cues that enable users to select a link with confidence during fact-finding. This paper investigates how blind users who navigate the web with screen-readers can bypass a scentless index with guided tours: a much simpler browsing pattern that linearly concatenates items of a collection. In a controlled study (N=11) at the Indiana School for the Blind and Visually Impaired (ISBVI), guided tours lowered user's cognitive effort and significantly decreased time-on-task and number of pages visited when compared to an index with poor information scent. Our findings suggest that designers can supplement indexes with guided tours to benefit screen-reader users in a variety of web navigation contexts.","PeriodicalId":378932,"journal":{"name":"Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility","volume":"12 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":"123623061","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 researchers have attempted to solve this problem with gestures, we explore a different modality: speech. We conducted a survey with 169 blind and sighted participants to investigate how often, what for, and why blind people used speech for input on their mobile devices. We found that blind people used speech more often and input longer messages than sighted people. We then conducted a study with 8 blind people to observe how they used speech input on an iPod compared with the on-screen keyboard with VoiceOver. We found that speech was nearly 5 times as fast as the keyboard. While participants were mostly satisfied with speech input, editing recognition errors was frustrating. Participants spent an average of 80.3% of their time editing. Finally, we propose challenges for future work, including more efficient eyes-free editing and better error detection methods for reviewing text.","PeriodicalId":378932,"journal":{"name":"Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility","volume":"13 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":"123979476","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 are currently few, if any, methods to determine this information a priori via computational tools or services. In this paper, we introduce and evaluate a new scalable method for collecting bus stop location and landmark descriptions by combining online crowdsourcing and Google Street View (GSV). We conduct and report on three studies in particular: (i) a formative interview study of 18 people with visual impairments to inform the design of our crowdsourcing tool; (ii) a comparative study examining differences between physical bus stop audit data and audits conducted virtually with GSV; and (iii) an online study of 153 crowd workers on Amazon Mechanical Turk to examine the feasibility of crowdsourcing bus stop audits using our custom tool with GSV. Our findings reemphasize the importance of landmarks in non-visual navigation, demonstrate that GSV is a viable bus stop audit dataset, and show that minimally trained crowd workers can find and identify bus stop landmarks with 82.5% accuracy across 150 bus stop locations (87.3% with simple quality control).","PeriodicalId":378932,"journal":{"name":"Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility","volume":"6 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":"122563946","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}
