Head-Tracking Techniques for Virtual Acoustics Applications

Authors: Hess, Wolfgang

AES Convention 133 · Paper 8782 · October 2012

Abstract

Synthesis of auditory virtual scenes often requires the use of a head-tracker. Virtual sound fields benefit from continuous adaptation to a listener’s position while presented through headphones or loudspeakers. For this task position- and time-accurate, continuous robust capturing of the position of the listener’s outer ears is necessary. Current head-tracker technologies allow solving this task by cheap and reliable electronic techniques. Environmental conditions have to be considered to find an optimal tracking solution for each surrounding and for each field of application. A categorization of head-tracking systems is presented. Inside-out describes tracking stationary sensors from inside a scene, whereas outside-in is the term for capturing from outside a scene. Marker-based and marker-less approaches are described and evaluated by means of commercially available products, e.g., the MS Kinect, and proprietary developed systems.
