Sensorama is equiped with a 5x2m large stereosopic Cyviz Vizwall back-projection screen, a surround sound system, and sensors to track the users.
Head mounted displays are also commonly used in VR simulations. We dispose of three Z800 3DVisor glasses. It is an affordable investment for potential partners willing to collaborate on VR applications. A custom mobile and variable sensitivity evaluation system allows to record and analyse experimentations or therapeutic sessions. It enables simultaneous use of up to seven infrared high sensitivity cameras to gain maximum information data from an 'inhabited information space'. The Noldus Observer XT professional software package is used for the collection, analysis and presentation of observational data. The Sensorama room is in the basement of the AAUE main building (B007). Before seting up the projection system, a large hole has been made in the wall. A door with tint glass allows to see through without being seen. The screen itself has been custom-buit in U.S. to the exact dimensions of the room. A rigid frame has been built by Cyviz to mount the projectors. The Cyviz Vizwall setup itself stands behind the screen. The 4 video projectors are adjusted and stabilized on the frame. Two pairs of projectors are used for each horizontal half of the screen. The Cywiz xpo boxes convert active to passive stereo video signals. The projectors have to be perfectly aligned: it took two days for the technician to tune it! Then, polarizing filters are placed between projectors and screen: without glasses both images are visible and the screen seems fuzzy. Only people wearing polarizing glasses will percieve the stereoscopic effect. In the final setup, the simulation is driven from a dedicated PC which is controlled through network. From the control desk, one can supervise the execution of the demo and observe public's reaction. Valid HTML 4.01 Transitional
