A VR game platform built upon wireless sensor network

Abstract

This paper presents a VR game platform built upon wireless sensor network (WSN). The WSN is composed of multiple beacons and a receiver. Each beacon transmits both an ultrasonic pulse and the RF message at the same time. Then, the receiver attached to a moving device uses the standard time difference of arrival technique to estimate its distance from each beacon. The estimated distances are passed to the context-aware game server, which computes the location of the receiver. The location data are fed into VR games, and determine the virtual device's motion. The prototype implementation proves that WSN and VR games can be neatly integrated, and can lead to a new type of natural interface for the next-generation game. © Springer-Verlag Berlin Heidelberg 2006.
