Unconscious Visual Effects for Enhancing Concentration in Virtual Reality

This study investigated the effectiveness of unconscious visual effects in VR for enhancing concentration. The research evaluated four visual effects (blur, chromatic aberration, mosaic, peripheral vignetting) applied to peripheral vision through two experiments: first determining detection thresholds, then assessing concentration impact through typing tasks. 20 participants identified effect thresholds using the method of limits, followed by 15 participants testing concentration effects. Results showed blur and peripheral vignetting significantly improved typing accuracy and reduced keystroke intervals, supported by subjective evaluations. The research demonstrates potential for enhancing concentration through peripheral visual modifications without conscious awareness.
