The overall principle is to create intelligent software agents used to assist visually impaired individuals in accessing complex on-line data organizations (e.g., tables, frame structures) in a meaningful way. Accessibility agents make use of knowledge representation structures (automatically or manually derived) to assist users in developing navigation plans; these are employed to locate given pieces of information or to answer user's desired goals.","PeriodicalId":179665,"journal":{"name":"Conference on Universal Usability","volume":"115 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124180180","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}

Advancing technology may offer ways to augment and supplement human care, if it is sensitively designed with the needs of potential users always taken into account. Developing an interface that a person with dementia can make sense of and use is a difficult goal. Beginning to meet this challenge is one aspect of a programme we have embarked on to develop a multi-media system that can be used to help people with dementia communicate better with others. Reminiscence work with people with dementia is a valuable tool for enabling them to participate meaningfully in conversations. We are developing a system which uses multimedia technology as an effective vehicle for delivering reminiscence stimulus and thus conversation support for people with dementia.","PeriodicalId":179665,"journal":{"name":"Conference on Universal Usability","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130539565","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}

Input to such devices is painfully slow and subject to high error rates with the resulting output not reliably reflecting the true intentions of the user. Conversational prediction has been incorporated into assistive systems to help speed up communication but could be further improved by considering the contextual interaction between the user and conversant. Contextual information applied to user profiles can greatly enhance conversational prediction and increase a severely disabled user's control over his or her complex world. We present a framework that integrates a rich profile of the user, a model of the user's environment, and actors on that environment. To test the validity of the framework, we develop a set of profiles and apply them in two different scenarios. Initial results show that the context-aware user profiles can increase both the accuracy and speed of the communication.","PeriodicalId":179665,"journal":{"name":"Conference on Universal Usability","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132020615","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}

This paper proposes to investigate the improvement of the user reading comprehension by different factors. Two main experiments tested how an explicit display of a small collection of keywords and a summary explanation aid reading comprehension. Twelve subjects were used for the first experiment and eight subjects for the second experiment. All were UIC undergraduate and graduate students, with computer experience. In the post experimentation stage, the subjects recommended different techniques for reading improvement. Comprehension was estimated by two procedures, a quantitative evaluation by a comprehension questionnaire and a qualitative evaluation by the subjective report. Important results were pointed out by the subjective evaluation. The advantages and disadvantages were summarized by a small focus group of users. A Dynamic Reading Device was designed for experimentation usage.","PeriodicalId":179665,"journal":{"name":"Conference on Universal Usability","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121386884","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}

Configuring an interface to match a particular user's requirements can be a demanding task. This paper focuses on the potential utility of configuration agents to support users with low initial levels of control, or low levels of knowledge about configuration. The relationship between configuration of systems by agents, user control, and user privacy is discussed. It is argued that privacy issues are of primary importance, and suggestions are made for ways to apply agent technologies to the configuration problem without compromising user control and privacy. Work in progress to inform and further develop these issues is described.","PeriodicalId":179665,"journal":{"name":"Conference on Universal Usability","volume":"80 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114042937","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 purpose of the project was to understand the experiences of elders and their caregivers in order to: 1) study the eldercare experience from the perspective of primary stakeholders; 2) to assess the importance of psychological and social factors in the eldercare experience; and 3) to identify implications for product, interface, and interaction design and opportunities for new products and technologies. Our findings show that social, emotional, and environmental factors play a key role in the eldercare experience and the adoption and use of new products.
