Figure 1. A participant who believes he is aiming at the virtual game board directly in front of him. ABSTRACT Without force feedback, a head-mounted display user's avatar may penetrate virtual objects. Some virtual environment designers prevent visual interpenetration, making the assumption that prevention improves user experience. However, preventing(More)
—When a virtual environment system prevents a user's avatar hand from penetrating virtual objects, the seen and felt positions of the hand separate. We propose a new method for reducing this position discrepancy as quickly as possible without introducing perceptible discrepancy between the seen and felt motion of the user's hand. We performed one user study(More)
We investigated the ability of a user in a head-mounted display virtual environment to detect a virtual hand avatar moving at a speed different than that of the real hand. We measured discrepancy detection thresholds for each of the six cardinal directions of 3-space (left, right, up, down, toward, and away). For each of these six directions we measured two(More)
