A Design of BCI based Environment System for Immersion of FPS Game

Abstract

We present a methodology about BCI (brain computer interface) based environment system for immersion of FPS game play. FPS (First- person shooter) game is a video game genre centered on gun and projectile weapon-based combat through a first-person perspective, immersion is important factor in this game. FPS game designer effort to raise players immersion when make game using interface, graphic effect, sound etc. We implemented real-time game environment changing system using the BCI to raise the degree of immersion in FPS game. EEG 1 is the recording of electrical activity along the scalp. We measure user’s EEG using MindSet 2 for implemented game playing time to get user’s concentration rate. This value operates our environment system in virtual space. In virtual space, each player experience different environment situation because each player has various concentration rate. Implemented environment system is formed with alternation of day with night and weather. Human body condition is changed depending on day and night. Player can feel change of character’s condition via player’s condition by our system. Implemented system can be applied to various game genres to raise player’s immersion for game playing time.
