Abstract

An improved head-mounted visual display apparatus that may find particular use in a virtual reality system. The apparatus includes a shell that encases a pair of visual displays and is mounted to a headband, which adjusts to the user's head, with a mounting device that allows the shell to be slid towards and away from the user's face. The mounting device includes a mounting bracket that attaches to the headband and a support member that slides across the mounting bracket. The support member is attached to the shell allowing the shell to be moved towards and away from the headband. Additionally, the support member allows for the attachment of video display units.
