These technologies may enable older adults to age-in-place more successfully. However, many app creators fail to do needs assessments of their end-users. To rectify this issue, we involved older adults (aged 65+) in the beginning stages of designing a mobile health and wellness application. We conducted a participatory design study, where 5 groups of older adults created 5 designs. Four groups identified at least 1 health metric not currently offered in either the iPhone app store or the Google Play store. At the end of the sessions we administered a questionnaire to determine what health topics participants would like to track via smartphone or tablet. The designs included 13 health topics that were not on the questionnaire. Seventeen of eighteen participants expressed interest in tracking health metrics using a smartphone/tablet despite having little experience with these devices. This shows that older adults have unique ideas that are not being considered by current technology designers. We conclude with recommendations for future development, and propose continuing to involve to older adults in participatory design.","PeriodicalId":378932,"journal":{"name":"Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility","volume":"142 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":"124205339","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}

Furthermore, the investigation indicates that the deaf community is more self-enclosed and won't exchange ideas with the hearing. To address this challenge, we develop VisualComm, a tool to support communication between deaf and hearing persons with sign language recognition technology by using the Kinect. The main contribution of the system is a holistic solution of a two-way communication between deaf and hearings, and furthermore it is a seamless experience tailored for this particular activity. Currently we have implemented the basic communication based on 370 daily Chinese words for signer.","PeriodicalId":378932,"journal":{"name":"Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility","volume":"9 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":"116782791","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}

Both unmet content and functionality expectations have been identified as central factors on the lack of coverage shown by guidelines. We expand on this by examining the role played by subjective dimensions, and particularly expectations, on the perception that users have on web accessibility. We conducted a study with 11 blind users to explore how these expectations shape the perception of web accessibility. Our preliminary findings corroborate that expectations can affect the perception of web accessibility. Additionally, we find that expectations on the Web are built up on previous experiences and prejudices. What is more, we reveal that these expectations are not only shaped by previous Web usage, but also by real life experiences. Our outcomes suggest that user expectations should be considered in user tests.","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":"130124149","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}

A visual-to-auditory Sensory Substitution Device (SSD) may help improve the quality of their lives by transforming visual cues into auditory cues. In this paper, we describe the design and development of a robust and real-time SSD called iFEPS -- improved Facial Expression Perception through Sound. The implementation of the iFEPS evolved over time through a participatory design process. We conducted both subjective and objective experiments to quantify the usability of the system. Evaluation with 14 subjects (7 blind + 7 blind-folded) shows that the users were able to perceive the facial expressions in most of the time. In addition, the overall subjective usability of the system was found to be scoring 4.02 in a 5 point Likert scale.","PeriodicalId":378932,"journal":{"name":"Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility","volume":"24 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":"127717101","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}

We present the design of an infra-red based active wayfinding system for the visually impaired. Our proposed system: downloads the floor plan of the building, locates and tracks the user inside the building, finds the shortest path and provides step-by-step direction to the destination using voice messages. The audio instructions include active guidance for impending turns in the path of travel, distance of each section between turns, obstacle warning instructions and position correction messages when the user gets lost. Results from a needs finding study with visually impaired individuals formed the design of the system. We then deployed the system in a building and field tested it with users using a standardized before-and-after study. The comparison of the results demonstrated that the system is usable and useful.","PeriodicalId":378932,"journal":{"name":"Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility","volume":"276 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":"124444832","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}

As people with vision impairments often have different requirements for technology, it is important to understand users' ever-changing needs. We conducted a formative study exploring how people with vision impairments used technology to support navigation. Our findings from interviews with 30 adults with vision impairments included insights about experiences in Orientation & Mobility (O&M) training, everyday navigation challenges, helpful and unhelpful technologies, and the role of social interactions while navigating. We produced a set of categorical data that future technologists can use to identify user requirements and usage scenarios. These categories consist of Personality and Scenario attributes describing navigation behaviors of people with vision impairments. We demonstrate the usefulness of these attributes by introducing navigation-style personas backed by our data. This work demonstrates the complex choices individuals with vision impairments undergo when leaving their home, and the many factors that affect their navigation behavior.","PeriodicalId":378932,"journal":{"name":"Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility","volume":"47 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":"127224402","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 three levels of line spacing (single, 1.5, and double) and 2 types of text justification (left only and left-right) were studied. Neither variable had a significant effect on performance measures, although both younger and older adults preferred 1.5 or double spacing over single spacing. There were no significant differences in preferences for left versus left-right justification. These results suggest that contrary to common recommendations, 1.5 or double spacing should be recommended for all users, not only older users and that no recommendation is needed on text justification.","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":"129487143","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}

Findings have shown tasks involving facial gestures, such as blinks and smiles, can be performed and detected by an Augmented and Alternative Communication (AAC) system within a shorter period of time compared to brow movements. As tasks increase in complexity, rates of accuracy and time taken remain relatively constant for blinking gestures, highlighting their potential in AAC interfaces. We aim to refine such a system to better address the needs of individuals with disabilities, by limiting input errors from involuntary movements and examining ways to reduce interface navigation time. Insights gained from the study offer promise to interface designers seeking to widen access to their interfaces using gestural input.","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":"121294102","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}
