Tactile Displays in Virtual Environments

Abstract

Virtual Reality (VR) technology allows the user to perceive and experience sensory contact with a non- physical world A complete Virtual Environment (VE) will provide this contact in all sensory modalities. However even state-off-the-art VEs are often restricted to the visual modality only. The use of the tactile modality might not only result in an increased immersion but may also enhance performance An example that will be discussed in this paper is the use of the tactile channel to support the processing of degraded visual information. The lack of a wide visual field of view in VEs excludes the use of peripheral vision and may therefore degrade navigation orientation motion perception. and object detection. However. tactile actuators applied to the torso have a 36Oc horizontal field of touch and may be suited to present navigation information.
