New commercially available interactive 3D tracking devices and systems for use in virtual environments are discussed. InterSense originally introduced the IS-900 scalable-area hybrid tracking system for virtual environments in 1999. In response to customer requests, we have almost completely revamped the system over the past two years. The major changes include a drastic 3-fold reduction in the size and weight of the wearable sensor devices, introduction of wireless tracking capability, a standardized I2C interface to allow OEM system integrators to add additional custom controls, and evolution of the system software interfaces, the performance, and the price. This paper will briefly describe the underlying technology changes that have allowed these advances to occur, and will outline some of the configuration possibilities that are now supported. Specific examples of how these devices and systems are being used to improve productivity in oil & gas seismic analysis & well field planning;& well field planning; automotive design & test; and, industrial/military training applications will be used to illustrate. Customization standards and future developments are discussed.
