Abstract

The goal of this VR system is to simulate a puzzle / challenge for adaption in cognitive rehabilitation training. Development of the VR system is inspired by a 1st person puzzle-platform game where the player must navigate and complete through a series of puzzle rooms with each room being more difficult than the last. The unique features in this work include the use of “portals” and “portal gun”. The portal gun allows the player to shoot two separate “portals” on walls that will allow anything to be teleported from one portal to the other. Implemented on the Unity engine and SteamVR, the VR Toolkit is employed in modeling and script development. Technical innovations are made in modeling the animated and self-collision detectable spider; upon being collided with a weapon (bullet or blade) it uses a special dissolve shader to give the effect of disappearing gradually from the game. We present the specific tasks of cognitive rehabilitation, conceptualization of VR techniques and the detailed implementation of the system.
