What is often missing from many virtual worlds is a physical sense of the confinement and constraint of the virtual environment. To address this issue, we present a method for providing localized cutaneous vibratory feedback to the user's right arm. We created a sleeve of tactors linked to a real-time human model that activates when the corresponding body area collides with an object. The hypothesis is that vibrotactile feedback to body areas provides the wearer sufficient guidance to acertain the existence and physical realism of access paths and body configurations. The results of human subject experiments clearly show that the use of full arm vibrotactile feedback improves performance over purely visual feedback in navigating the virtual environment. These results validate the empirical performance of this concept.
