Abstract: Due to recent improvements in virtual reality (VR) technology, the number of novel applications for entertainment, education, and rehabilitation has increased. The primary goal of these applications is to enhance the sense of belief that the user is “present” in the virtual environment. By tracking the user’s skeleton in real-time, it is possible to synchronize the avatar’s motions with the user’s motions. Although current common devices implement body tracking to a certain degree, most approaches are limited by either high latency or insufficient accuracy. Due to the lack of positional and rotation data, the current VR applications typically do not represent the user’s motions. In this paper, we present an accurate, low-latency body tracking approach for VR-based applications using Vive Trackers. Using a HTC Vive headset and Vive Trackers, we have been able to create an immersive VR experience, by animating the motions of the avatar as smoothly, rapidly and as accurately as possible. An evaluation showed our solution is capable of tracking both joint rotation and position with reasonable accuracy and a very low end-to-latency of 6.71 ± 0.80 ms. Due to this merely imperceptible delay and precise tracking, our solution can show the movements of the user in real-time in order to create deeper immersion.
