| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Automatic driving technology frees the driver from driving operations and allows the driver to freely perform activities inside the vehicle as a passenger. However, acceleration stimuli from the vehicle may cause discomfort during comfortable in-vehicle activities. In a previous study, they focused on the passenger's sense of movement, which is one of the causes of discomfort, and reduced the sense of movement by controlling the acceleration stimuli perceived visually and physically. However, the wearing feeling of the HMD and VR sickness reduced comfort, and tilt control algorithm to reduce the sense of movement was not proposed. In this study, as in previous studies, I focus on the reduction of the sense of movement by visual and physical control, and aim to build a system that comfortably reduces the sense of movement and to realize an tilt control algorithm. The proposed system, XR cabin, consists of an immersive hemispheric screen that enables VR presentation using omnidirectional images and a motion platform that tilts and controls the entire cabin, which consists of the screen and seats. By calculating from the entirety of the predicted acceleration stimulus, the cabin's tilt control algorithm can estimate the optimal tilt, considering tilt speed limitations and the characteristics of human acceleration perception. Experiments were conducted on 29 subjects to verify the effectiveness of the proposed method in reducing the sense of movement and improving comfort. The experimental conditions were four conditions, combining the cases with and without visual control and with and without sensory control. In each condition, the subjects evaluated the sense of movement using a joystick in real time and a questionnaire after driving. The results of the experiment showed that the sense of movement was significantly reduced in the condition with both visual and physical control compared to the condition without either control. In addition, the sense of movement in the direction of rotation tended to be reduced more in the condition with both visual and physical control than in the condition with only visual control. Therefore, combining both visual and physical control is effective in reducing the sense of movement. |
