Reduce motion sickness and increase immersion Expect to expand self-driving content 'ACM CHI 2026' Ahead of the era of fully autonomous driving, a technology has been developed by domestic researchers to increase the sense of immersion in VR content that can be enjoyed in vehicles while reducing motion sickness. Gwangju Institute of Science and Technology (GIST) announced on the 18th that a research team led by Kim Seung-joon, a professor of AI convergence, has developed an in-vehicle XR (Extended Reality) technology called Force Mapping that utilizes the actual movement of vehicles as a VR environment change factor. With the development of autonomous driving technology, more and more attempts are being made to use the interior of vehicles as games, videos, education, and work spaces, but dizziness and immersion problems have been pointed out as limitations due to differences between vehicle movement and VR screens. The research team solved this problem by connecting the acceleration, deceleration, rotation, and road vibration of the vehicle to visual effects and spatial changes in VR. When the vehicle's inertial measurement unit (IMU) and GPS module detect movement in real time, effects such as spatial shaking, waves, waves, and falling objects react together on the VR screen. As a result of the study, it was found that when movement is expressed in the form of environmental change, immersion and situational awareness are improved and the level of motion sickness is reduced compared to the conventional method of simply reproducing vehicle movement. In particular, the research team also confirmed that it is more natural to express the direction and strength of the vehicle by emphasizing some of it rather than implementing the physical movement of the vehicle in the same way as it actually is. The effects of "ground tilt" and "space shaking" are typical examples. This
