Diminished Reality for Acceleration — Motion Sickness Reduction with Vection for Autonomous Driving

This paper proposes the Diminished Reality (DR) method for an acceleration stimulus to reduce motion sickness for an autonomous vehicle by presenting vection for user before the real acceleration occurs. The technology of an autonomous vehicle has been rapidly developed in all over the world. Instead of controlling vehicle by passenger themselves, the autonomous system helps them acceleration and deceleration controls and safety controls as well. However, it is predictable that the number of passengers who get motion sickness increases because they receive an unexpected acceleration stimulus for the autonomous driving.In the field of the Virtual Reality, the technology to create virtual acceleration stimulus to the passenger in the driving simulator or flight simulator have been developed. However, our approach for using pseudo to reduce the acceleration stimulus which occurs in autonomous driving to prevent the motion sickness is the opposite problem of these conventional VR researches. The real acceleration stimulus from the vehicle is reduced by presenting vection before the real acceleration occurs.In this research, we demonstrate the idea of technology that use the vection with an augmented reality system to reduce an effect of the real acceleration in the vehicle which mainly the factor for the motion sickness.
