| Abstract | Figure 1: PDA client of a collaborative virtual environment, Sharp Zaurus which study mainly in the evening and on weekends. Therefore, there is a need for mobile solutions of learning environments for synchronous events at a fixed timeslot. We developed a client/server based multiuser virtual reality environment (collaborative virtual environment, CVE, based on Java and VRML) to offer our students a 'virtual campus'. We modified a Java applet based DeepMatrix[1] client of the 'virtual campus' in a way that it can be used by mobile users (equipped with PDAs or smartphones). The modified client is now based on a Java application which runs on a Personaljava virtual machine. Personaljava [2] is a Java runtime environment for mobile devices with limited resources (e.g. graphic resolution of 240x320 pixel, no hardware 3D acceleration). Implementations of Personaljava are available for Windows CE, Linux, Palm and Symbian OS based PDA and mobile phone platforms. To provide location based services for local (campus) mobile PDA users, a GPS based localization is used together with the collaborative virtual environment. |
