This system provides a multimodal tangible user interface (TUI), enabling people with visual impairments to create, modify and naturally interact with diagrams and graphs on a multitouch surface. The system supports a novel notion of active orientation and proximity tracking of manipulatives against diagram and graph components. If the orientation of a MICOO matches a component, then a user is allowed to modify that component by moving the MICOO. Conversely, if a MICOO does not match orientation or is far from a component, audio feedback is activated to help the user reach that component. This will lessen the need for manual intervention, enable independent discovery on the part of the user, and offers dynamic behavior, whereas the representation interacts and provides feedback to the user. The platform has been developed and it is undergoing formal evaluation (e.g., browse, modify and construct graphs on a Cartesian plot and diagrams).","PeriodicalId":351090,"journal":{"name":"The proceedings of the 13th international ACM SIGACCESS conference on Computers and accessibility","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133011319","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}

Blind individuals are thus hindered in their interaction capabilities. To address this, we are building a computer vision system with facial recognition and expression algorithms to relay nonverbal messages to a blind user. The device will communicate the identities and facial expressions of communication partners in realtime. In order to ensure that this device will be useful to the blind community, we conducted surveys and interviews and we are working with subjects to test prototypes of the device. This paper describes the algorithms and design concepts incorporated in this device, and it provides a commentary on early survey and interview results. A corresponding poster with demonstration stills is exhibited at this conference.","PeriodicalId":351090,"journal":{"name":"The proceedings of the 13th international ACM SIGACCESS conference on Computers and accessibility","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124876738","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}

Yet the relationship of human comprehension to PSNR has not been studied. In this survey, we determine how well PSNR matches human comprehension of sign language video. We use very low bitrates (10-60 kbps) and two low spatial resolutions (192×144 and 320×240 pixels) which may be typical of video transmission on mobile phones using 3G networks. In a national online video-based user survey of 103 respondents, we found that respondents preferred the 320×240 spatial resolution transmitted at 20 kbps and higher; this does not match what PSNR results would predict. However, when comparing perceived ease/difficulty of comprehension, we found that responses did correlate well with measured PSNR. This suggests that PSNR may not be suitable for representing subjective video quality, but can be reliable as a measure for comprehensibility of American Sign Language (ASL) video. These findings are applied to our experimental mobile phone application, MobileASL, which enables real-time sign language communication for Deaf users at low bandwidths over the U.S. 3G cellular network.","PeriodicalId":351090,"journal":{"name":"The proceedings of the 13th international ACM SIGACCESS conference on Computers and accessibility","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125362194","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}
