Movement-based interaction and event management in virtual environments with optical tracking systems
In this paper we present our experience in using optical tracking systems in Virtual Environment applications. First we briefly describe the tracking systems we used, and then we describe the application scenarios and present how we adapted the scenarios for the tracking systems. One of the tracking systems is markerless, that means that a user doesn\'t have to wear any specific devices to be tracked and can interact with an application with free hand movements. With our application we compare the performance of different tracking systems and demonstrate that it is possible to perform complex actions in an intuitive way with just small special knowledge of the system and without any specific devices. This is a step forward to a more natural human-computer interface.
