Abstract

Positional tracking ensures high presence in Virtual Reality (VR). Though mobile VR has a large potential to bring VR to the masses, enabling positional tracking on mobile VR platforms has been a challenge. Existing implementations often rely on computer vision or require special sensors and are often computationally intensive, resulting in a low frame rate and reduced battery life. We present StereoTrack; a 180° positional tracking method using acoustic sensing which has a low computational overhead, and is minimalistic in terms of required hardware (a pair of speakers); which may allow for large scale adoption. A number of studies evaluate Stereo-Track in terms of precision, accuracy, and effect on overall latency. We test the feasibility of StereoTrack in the context of two games that demonstrate its potential to enhance existing mobile VR interaction options.
