Integrated Virtual Reality Game Interaction: The Archery Game

Abstract

The aim of this research is to develop an innovative technology framework that allows a new type of human-computer interaction, where user's motion recognition is combined with immersive visualisation. The demonstrator program allows the user to visualise a virtual arrow on the top of a real physical crossbow used as game controller. Stereoscopic- 3D Visualisation is implemented using two virtual cameras with a variable angle between them (Automated Toed-in). An algorithm is also used to calculate the maximum acceptable dimension of the stereoscopic arrow, in relation with the screen size and the data provided by the Motion Capture system about the user position. The Motion Capture data are transmitted to the video game using a network interface demanded also to depacketize and process the motion data. Tests prove that the Stereoscopic-3D effect is strong enough to visualise the virtual arrow in a realistic position on the top of the crossbow. The theory formulated may be utilised to develop a new generation of Stereoscopic applications easy to use and immersive.
