Diminished reality for acceleration stimulus: Motion sickness reduction with vection for autonomous driving

This paper presents an approach for motion sickness reduction while riding an autonomous vehicle. It proposes the Diminished Reality (DR) method for an acceleration stimulus to reduce motion sickness for the autonomous vehicle. One of the main causes of motion sickness is a repeated acceleration. In order to diminish the acceleration stimulus in the autonomous vehicle, vection illusion is used to induce the user to make a preliminary movement against the real acceleration. The Balance Wii Board is used to measure participant's movement of the center of gravity to verify the effectiveness of the method with vection. The experimental result of 9 participants shows that the proposed method of using vection could reduce acceleration stimulus compared with the conventional method.
