Brain−computer interfaces (BCIs) hold great promise for improving information delivery and preserving user attention, but this promise has not yet translated to practical use. A prototype BCI that optimizes email notifications in noisy, complex environments, CARSON combines multiple measures from the brain to predict both cognitive workload and message relevancy to determine the optimum time to...

How can we reliably infer web users’ interest and evaluate the content relevance when lacking active user interaction such as click behavior? In this paper, we investigate the relationship between mobile users’ implicit interest inferred from attention metrics, such as eye gaze or viewport time, and explicit interest expressed by users. We present the first quantitative gaze tracking study usin...

This paper discusses how attention metadata enables collection of rich usage data. We use this attention to enhance users' models, predict usage patterns and feed personalization and recommender systems. We argue that attention metadata extends the information on user attention which can be derived from current log services. Furthermore, frameworks and schemas that enable tracking and merging r...

nowadays, with the development of human societies and more mastery over the environment, to environmental changes caused by the faster and wider than before the occurrence of the joins. so having the necessary information about these changes and to manage the natural order is essential to sustainable ecosystems, metrics of landscape is tools landscape situation are few mechanisms that cause the...

about multiple sources of information while engaged in other tasks. Notification systems are interfaces specifically designed to support user access to additional digital information from sources secondary to current activities. Many such interfaces, especially examples such as Web page advertisements and animated software agents, seem to be ineffective and distracting, and are abandoned or ign...

Considering the amount of devices a user owns nowadays, a distributed user interface can become increasingly important. This requires reasoning techniques that allow making predictions of future values in the spatial model because these devices can be expected to change their location during usage. Our primary attention will be devoted to the problem of re-distribution of user interfaces in a c...

background: in patients with hepatitis b and c, environmental factors such as smoking and alcohol can cause liver fibrosis progression. but opium effects on liver fibrosis progression are not clear. this study was designed to assess the relationship of opium user and liver fibrosis progression. methods: in this case-control study, sixty patients in hepatitis b group and sixty patients in hepati...

Web page prediction is a popular personalized service on the Web and has attracted much research attention. One of the most successful and widely used approaches is collaborative filtering. Traditional collaborative filtering requires explicit user participation for providing his/her interest to the pages. However, they suffer from some limitations such as additional user effort, user behavior ...
