Experiments using this system reached 60% success in average, achieving a success rate of 90% for joy and sadness.","PeriodicalId":154697,"journal":{"name":"Simpósio Brasileiro de Fatores Humanos em Sistemas Computacionais","volume":"147 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":"126282192","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}

Fitts' law was found to be applicable, but had R2 lower than for younger subjects. On average, it took elder participants twice as much time to complete movement tasks, but their accuracy was two times higher. Error level was affected by small (8 pixels) target size, but not by movement distance. Mean throughput was 4.58, but only 3.29 for senior subjects. Extended regression models, incorporating factors of subjects' age and experience, were proposed for movement time and throughput, providing a useful insight for HCI researchers and interface designers.","PeriodicalId":154697,"journal":{"name":"Simpósio Brasileiro de Fatores Humanos em Sistemas Computacionais","volume":"57 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":"115286543","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 the knowledge to be taught is usually well expressed in the curriculum material, the knowledge of a typical student is harder to codify. In this paper, it is shown how a large knowledge base of common sense statements can be used to help model student knowledge and consequently to help teachers plan learning actions by\u0000 • Identifying topics that need coverage by the curriculum;\u0000 • Identifying what a student is already likely to know;\u0000 • Locating possible misconceptions that need to be corrected; and\u0000 • Assuring that the student understands the vocabulary needed to express relevant subject material.","PeriodicalId":154697,"journal":{"name":"Simpósio Brasileiro de Fatores Humanos em Sistemas Computacionais","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114594933","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}

Usually, searches are submitted based on few terms and the results are dozens of links listed through several pages. Different criteria are used by the search engines to establish the order in which the links appear in this list. Often, the user has to browse the list until finding the relevant information. This scenario increases the need of alternative forms of displaying search results. Although internet services become more attractive when providing information through graphical representations, surprisingly very few initiatives have been devoted to the practical use of visual representations of search results. The present work addresses this issue by presenting a study about the experience and satisfaction of subjects when using two web search tools which display their results graphically.
