Integration of Multidimensional Interaction Devices in Real- Time Computer Graphics Applications

摘要

Modern CAD/CAM and Virtual Reality applications cannot be imagined without the new class of interaction devices allowing the user direct interaction with computer generated scenes. Integrating such devices into existing or newly developed software is a complex task for a number of reasons. The set of devices is very heterogeneous in functionality and data formats. Most devices are difficult to handle by inexperienced users or need careful handing and calibration. After reviewing a number of existing systems, a novel approach to this problem is presented. A device interface that allows the flexible, hardware independent configuration and error robust operation, even reconfiguration and exchanges of interaction devices during operation, will be introduced. The system structure is discussed and novel communication protocols reducing latency are invented.
