OpenTracker

OpenTracker is developed to be generic solution to the different tasks involved in tracking input devices and processing tracking data for virtual environments. It provides an open software architecture based on a highly modular design and a configuration syntax based on XML, thus taking full advantage of this new technology. OpenTracker is a first attempt towards a "write once, track anywhere" approach to virtual reality application development. Some features of OpenTracker include :

• a generic data flow network - to describe complex manipulations of data as a series of simple transformations based on an object-oriented graph structure
• an extensible C++ class library
• transparent network access
• XML-based configuration
• Flexible event model
  • event based : event data is passed through a graph of nodes
  • time based : continous functions in time can be configurated and evaluated

As a collaboration between TU Graz, University of Oslo, and Brigham and Women's Hospial (Boston), OpenTracker was augmeted to allow for generic attribute types and dynamic attributes. This greatly enhanced the usability of OpenTracker in medical device integration, beyond trackers
