Context -aware applications take into account the user's current context (e.g. the location). Many applications, e.g., tourist guides or office and meeting tools, use context information to adapt to a specific situation. Most of the actual systems use proprietary platforms and infrastructures to deal with context information, thus benefits are not directly available for a large community. The World Wide Web, on the other hand, is a well-established, widely available platform for a huge number of networked applications. In this paper, we present the PinPoint platform, which combines the benefits of the World Wide Web with context -aware computing. With PinPoint, a developer of context -aware web applications can concentrate on the application function and web contents and has not to deal with different client and server platforms or the capturing of contextual data. Context -aware web application can use existing web browsers and servers off the shelves, thus developers as well as end-users can use reliable and well-known software environments. PinPoint is especially designed for mobile applications that take into account the user's current location. Since applications can react on the device type (PC, PDA, mobile phone), web applications can produce output in an appropriate format. We demonstrate the strength of PinPoint with the help of a location-aware tourist guide, which runs on notebooks and PDAs.
