In this paper, we describe our work on developing a system to support the personalization of a captured public experience. Specifically, we are interested in providing students with the ability to personalize the capture of the lecture experiences as part of the Classroom 2000 project. We discuss the issues and challenges involved in designing a system that performs live integration of personal streams of information with multiple other streams of information made available to it through an environment designed to capture public information.
Navigation services (e.g., in-car navigation systems and online mapping sites) compute routes between two locations to help users navigate. However, these routes may direct users along an unfamiliar path when a familiar path exists, or, conversely, may include redundant information that the user already knows. These overly complicated directions increase the cognitive load of the user, which may lead to a dangerous driving environment. Since the level of detail is user specific and depends on their familiarity with a region, routes need to be personalized. We have developed a system, called MyRoute, that reduces route complexity by creating user specific routes based on a priori knowledge of familiar routes and landmarks. MyRoute works by compressing well known steps into a single contextualized step and rerouting users along familiar routes.
