Tracking the User and Environment

Abstract

Virtual reality allows different methods of interaction and communication between the user and virtual world. An important aspect of the virtual reality system in this regard is the tracking of the user's pose and actions. In this chapter methods and technologies that define inputs to a virtual reality system are presented. These include pose sensors (mechanical, ultrasonic, optical, electromagnetic, and inertial) as well as force and torque sensors. The chapter concludes with a summary of motion tracking concepts and physical input devices. © Springer Science+Business Media Dordrecht 2014.
