Television typography is no longer limited to teletext, subtitles and captions. It provides navigation, tickers, tabulated results, info-graphics and is embedded in videos and games. At the same time, screen resolution is improving, and the size of household screens are increasing. Currently, little is known about what user needs are associated with these advances. With the use of a customisation prototype, the research explores television typography by understanding the preferences of a variety of users; people with cognitive and sensory access needs, older users and users with no stated access needs. The results from the first study showed participants preferred a larger font size than the current television standard. This preference was particularly prevalent when text was presented along with other content elements demanding attentional focus. The font type Helvetica Neue was particularly favoured by participants with access needs. The second study aims to establish a further exploration into font size for differing interactive environments. We seek to develop the prototype to test and improve the accessibility of interactive TV services.","PeriodicalId":351090,"journal":{"name":"The proceedings of the 13th international ACM SIGACCESS conference on Computers and accessibility","volume":"40 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":"131239464","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 reality, many studies have shown that young people, especially children, are attracted towards computer games. Often, they play these games with great interest and attention. Thus, the idea of using serious games to provide education is attractive for most of them. This work is situated in the context of Project CLES. This project, in collaboration with many research laboratories, aims at developing an Adaptive Serious Game to treat a variety of cognitive handicaps. In this context, this article presents a system that generates learning scenarios keeping into account the user's profile and their learning objectives. The user's profile is used to represent the cognitive abilities and the domain competences of the user. The system also records the user's activities during his/her interaction with the Serious Game and represents them in interaction traces. These traces are used as knowledge sources in the generation of learning scenarios.","PeriodicalId":351090,"journal":{"name":"The proceedings of the 13th international ACM SIGACCESS conference on Computers and accessibility","volume":"62 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":"126198966","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, avatar research is characterized by the fact that most researchers are not members of the Deaf community, and that Deaf people as potential users have little or no knowledge about avatars. Therefore, we suggest two well-known methods, focus groups and online studies, as a two-way information exchange between research and the Deaf community. Our aim was to assess signing avatar acceptability, shortcomings of current avatars and potential use cases. We conducted two focus group interviews (N=8) and, to quantify important issues, created an accessible online user study(N=317). This paper deals with both the methodology used and the elicited opinions and criticism. While we found a positive baseline response to the idea of signing avatars, we also show that there is a statistically significant increase in positive opinion caused by participating in the studies. We argue that inclusion of Deaf people on many levels will foster acceptance as well as provide important feedback regarding key aspects of avatar technology that need to be improved.","PeriodicalId":351090,"journal":{"name":"The proceedings of the 13th international ACM SIGACCESS conference on Computers and accessibility","volume":"7 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":"133738012","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, clothing is almost exclusively perceived visually begging the question: \"How is beauty in fashion interpreted by those with vision impairments?\" We conducted face-to-face interviews and a diary study with eight legally blind participants to gain the perspectives of those with vision impairments on what makes clothing attractive and appealing. Our primary focus was gathering their point-of-view on beauty in clothing but all of the participants also discussed accessibility challenges of clothing and fashion. We report our findings on the major aspects of clothing's appeal to blind wearers as well as the challenges with lack of access and assistive technology. These findings have far-reaching implications for future research within fashion design, interaction design and assistive technology.","PeriodicalId":351090,"journal":{"name":"The proceedings of the 13th international ACM SIGACCESS conference on Computers and accessibility","volume":"32 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":"134371884","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 participant strongly demanded to improve the low accuracy and the slow software keyboard typing, and the poor understanding of the shape of the picture. She was also interested in recognizing the 3D shapes. Thus, we developed a fingertip tactile feedback system in order to indicate the \"f\" and \"j\" key for touch-typing and improved the speed of the software keyboard typing, and simplify the way to understand the 3D shapes. In this paper, we introduce and evaluate the recognition of the 3D shape by three participants using the system.

The game was designed to enable learners to practice their phonological awareness skills independently with minimal instruction from human instructors. Preliminary results of post-intervention assessments demonstrate general positive effects of the intervention upon the phonological awareness and literacy skills of the participants.
