BCI Sensor Based Environment Changing System for Immersion of 3D Game

Abstract

We present a methodology about game environment system based on BCI (brain computer interface) for immersion of FPS game play. FPS game is a video game genre centered on gun shooting and projectile weapon-based combat through a first-person perspective; immersion is important factor in this game. FPS game designer makes efforts to raise player's immersion using interface, graphic effect, sound, and so forth. We implemented real-time game environment system using game player's emotional state information from the BCI sensor to raise the degree of immersion in FPS game. We measured user's EEG signal using MindSet to take user's emotional state on playing game. We can get user's emotional state in 4 categories (attention/inattention, meditation/uneasiness) and this emotional state interacts with game environment system real time. In game environment space, each player experiences different environmental situation (lighting, fog) because each player has emotional state on each scene. We implemented game environment system to be changed (lighting, fog) on playing FPS game. Player can feel the change of game environment by our system. We found out that game environment system can be applied to various game genres to raise player's immersion on playing game.

Exploration of Prominent Frequency Wave in EEG Signals from Brain Sensors Network

“…They claim that the average accuracies of both models, subject-dependent and subject-independent, were approximately 75.62% and 65.12%, respectively. Cho and Lee [11] presented a methodology for game users which is based on Brain Computer Interface. The game called FPS is a common video game focused on gun shooting and projectile weapon based combat on a single user.…”

“…Generally, EEG data of single frequency band (0.5 to 70 Hz) are coming through secured sensors. It is established through previous studies [9][10][11][12] that the desired results from original frequency are difficult to achieve due to some noise artifacts and existence of other unknown signal patterns. We considered five frequency bands in our research, such as delta (0.5-4 Hz), theta (4-8 Hz), alpha (8-13 Hz), beta (13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30), and gamma (30-50 Hz), also denoted as , , ,…”

Development of a Novel Motor Imagery Control Technique and Application in a Gaming Environment

“…Sollfrank et al [ 49 ] showed that a realistic visualization in 3D of upper and lower limb movements can amplify motor related potentials better than in 2D visualization during subsequent motor imagery. Cho and Lee [ 50 ] implemented a real-time game environment system using game player's emotional state information from the BCI sensor to raise the degree of immersion in an FPS game. Kondo and colleagues [ 51 ] investigated the effect of static and dynamic visual representations of target movements during BCI neurofeedback training, which revealed that dynamic images showed significant improvement in generating MI-associated ERD compared with static images.…”

Design of a Brain-Controlled Video Game based on a BCI System

“…Most of current games based on the BCI interface as game play control have been developed to measure the emotional state of the players such as "Sudden Attack", a firstperson shooter game type, developed in Unity3D gaming engine based on ThinkGear BCI plug-in to communicate with PC and that is able to measure four category of emotional states of the player: the attention/inattention and the meditation/uneasiness according to the beta brainwave level recorded that influence the changing of the sky lightening in gameplay environment due to human biological clock [13]. The game playing screen shot is presented in Fig.…”
