摘要:We Navigation through the Web has problems of positioning and space-temporal reference marks. Therefore, it’s necessary to design some computer-aided tools to help the user to position himself in space and time during a navigation session. The user is provided with a map of visited sites, thus giving an explicit representation of virtual space. Various levels of visualization are set up to make the map more visible and less overloaded. A permanently displayed time indicator enables users to keep an eye on themselves and thus to optimize navigation time.
