In between, the Web 2.0, which changes the view on the web from mere computer network and services, to a social context, where the Web can be seen as a network of people composed of communities that collaborate and communicate with one another. Thinking about this, we proposed an interface prototype to the A3TV (Anytime, Anywhere and by Anyone TV), focusing on concepts like perception, communication and collaboration, all present in the Web 2.0. This platform intends to improve the Internet TV experience, providing content anywhere, anytime, and by anyone.","PeriodicalId":154697,"journal":{"name":"Simpósio Brasileiro de Fatores Humanos em Sistemas Computacionais","volume":"139 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122991915","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}

Some research towards the identification and model of user's Emotions have been done by Affective Computing researchers, however Personality Traits have been quite neglected. The World Wide Web is an enormous source of products and services available for people. There is a huge effort done by scientists towards the creation of effective strategies to personalize those products/services for each people interested in using them. By storing Personality Traits in User Profiles we intend to enable Recommender Systems in order to deduce more interesting recommendations for users acting proactively to offer them products/services as a consequence of a prediction of their future needs and behaviors. To fill this gap, in this work, we propose the interpretation, modeling, formalization, storing and application of Personality Traits in User Profile, followed by an experimentation developed in the context of Recommender Systems.","PeriodicalId":154697,"journal":{"name":"Simpósio Brasileiro de Fatores Humanos em Sistemas Computacionais","volume":"125 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116599289","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}

With the rapid evolution of graphics hardware and Computer Graphics, this becomes more pronounced. An undesirable consequence of this trend is that visually-impaired people get more excluded from the play. Mobile phones are pervasive nowadays, and can reach a potentially large user base, including the visually-impaired. However, in mobile gaming there seems to be only few alternatives to serve this community. This work presents an exploratory study on non-visual mobile phone interfaces for games. It is based on Semiotic Engineering principles, and emphasizes communication through aural, tactile and gestural signs. Results include a number of issues that can be incorporated to a wider research agenda about mobile gaming accessibility.","PeriodicalId":154697,"journal":{"name":"Simpósio Brasileiro de Fatores Humanos em Sistemas Computacionais","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127451335","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}
