Abstract
Representing users’ hands and fingers in virtual reality is crucial for many tasks. Recently, virtual reality head-mounted displays, capable of camera-based inside-out tracking and finger and hand tracking, are becoming popular and complement add-on solutions, such as Leap Motion.However, interacting with physical objects requires an accurate grounded positioning of the virtual reality coordinate system relative to relevant objects, and a good spatial positioning of the user’s fingers and hands.In order to get a better understanding of the capabilities of Virtual Reality headset finger tracking solutions for interacting with physical objects, we ran a controlled experiment (n =24) comparing two commodity hand and finger tracking systems (HTC Vive and Leap Motion) and report on the accuracy of commodity hand tracking systems.
