Accuracy Evaluation of Touch Tasks in Commodity Virtual and Augmented\n Reality Head-Mounted Displays

Abstract

An increasing number of consumer-oriented head-mounted displays (HMD) for\naugmented and virtual reality (AR/VR) are capable of finger and hand tracking.\nWe report on the accuracy of off-the-shelf VR and AR HMDs when used for\ntouch-based tasks such as pointing or drawing. Specifically, we report on the\nfinger tracking accuracy of the VR head-mounted displays Oculus Quest, Vive Pro\nand the Leap Motion controller, when attached to a VR HMD, as well as the\nfinger tracking accuracy of the AR head-mounted displays Microsoft HoloLens 2\nand Magic Leap. We present the results of two experiments in which we compare\nthe accuracy for absolute and relative pointing tasks using both human\nparticipants and a robot. The results suggest that HTC Vive has a lower spatial\naccuracy than the Oculus Quest and Leap Motion and that the Microsoft HoloLens\n2 provides higher spatial accuracy than Magic Leap One. These findings can\nserve as decision support for researchers and practitioners in choosing which\nsystems to use in the future.\n
