Tracking for virtual environments is necessary to record the position and the orientation of real objects in physical space and to allow spatial consistency between real and virtual objects. This paper presents a top-down classification of tracking technologies aimed more specifically at head tracking, organized in accordance with their physical principles of operation. Six main principles were identified: time of flight (TOF), spatial scan, inertial sensing, mechanical linkages, phase…
