A New Approach for Reducing Virtual Reality Sickness in Real Time: Design and Validation Study.

Area of Science:

• Human-Computer Interaction
• Virtual Reality Technology
• Neuroscience and Psychology

Background:

• Rapid development of streaming-based virtual reality (VR) content delivery systems.
• Limited research on real-time mitigation of VR sickness experienced during head-mounted display (HMD) use.
• Need for effective strategies to address user discomfort in immersive VR environments.

Purpose of the Study:

• To propose and evaluate a novel approach for real-time measurement and reduction of VR sickness.
• To adapt VR sickness interventions based on the user's current physiological state.
• To improve the user experience in VR by minimizing simulator sickness.

Main Methods:

• Implementation of a system to assess the user's real-time VR sickness level.
• Application of established VR sickness reduction techniques dynamically based on the measured sickness level.
• Experimental validation using a specific VR content type and three known VR sickness reduction methods.

Main Results:

• Significant reduction in VR sickness was observed across all experimental conditions (P<.05).
• The proposed approach demonstrated effectiveness in mitigating symptoms associated with VR usage.
• Validation of the real-time adaptation of VR sickness interventions.

Conclusions:

• VR sickness can be effectively measured without the need for additional wearable equipment.
• The developed approach enables real-time application of personalized VR sickness reduction strategies.
• Confirmation that the proposed method enhances user comfort and reduces VR sickness during HMD use.
