Inertial tracking systems for virtual reality devices

Abstract

Tracking systems are the most important components in virtual reality devices and appliances. In the simplest case, in order to represent current picture for a user of virtual reality glasses, it is required to provide head tracking. In complex devices of virtual reality, it is also required to track position of device itself and dynamics of its motions. This work is aimed at development of 3D positioning algorithms for virtual reality devices and appliances. In this work positioning is based on operation of inertial sensors. The issues of motion capture and calibration of inertial devices are considered as well as application of Madgwick filter for noise suppression and quaternions for description of coordinate rotation. This work discusses the application of the developed algorithms for various virtual reality devices and appliances.
