Multiple Head Mounted Displays in Virtual and Augmented Reality Applications

With the recent introduction of low cost head mounted displays (HMDs), prices of HMD-based virtual reality setups dropped considerably. In various application areas personal head mounted displays can be utilized for groups of users to deliver different context sensitive information to individual users. We present a hardware setup that allows attaching 12 or more HMDs to a single PC. Finally we demonstrate how a collaborative, educational, augmented reality application is used by six students wearing HMDs on a single PC simultaneously with interactive framerates.
