Development and evaluation of a wearable motion tracking system for sensorimotor tasks in VR environments

Abstract

The present communication reports on a series of experiments, aiming at exploring the effect of a virtual limb’s visibility on task performance inside interactive Virtual Environments. To this end, a motion tracking system was developed, capable of tracking the movement of the human arm beginning from the shoulder up to and including the palm. Twenty two university students participated in a shooting task experiment, divided into two groups. One group first completed the experiment with full visibility of the arm, and then without, while the other completed the experiment in the opposite manner. Results show that while the arm’s visibility had no significant effect on task performance, it does affect the subjects’ subjective experience within the environment.
