Inside view of the game.

For the EXPO REAL Exhibition booth of the HOCHTIEF diVision Vicon ("Virtual Design and Construction") the idea was to use an existing 3D Model of a building and combine it with a game. Visitors of the exhibition should be invited to seARCh certain objects and interact with the environment in realtime using a head mounted display (HMD). For this purpose 3D Data of an existing building was converted to use with realtime graphics and the customised game was developed with this three-dimensional environment.

Installation set-up at Expo REAL in Munich & User playing the game at the expo real

In the final installation at the exhibition the user was sitting into an special designed chair wearing a high-end HMD with 1280x1024 resolution and 3DOF tracking. Using an joystick the users where virtually exploring the the building and could interact with the environment inside while seARChing the hidden objects. For the visitors standing beside, the happening inside the game was displayed on a screen showing the view of the user. This was attracting further visitors walking by.

Because of the huge success of the game at the exhibition the set-up was also shown on the annual general meeting of HOCHTIEF in 2006.
