Bend your arm without losing your way ... VR technology developed to guide you with vibrations

[Financial News] A technology has been developed that allows users to find the right direction of travel using only vibrations, even when they raise or bend their arms inward while using a virtual reality (VR) device.
KU said on the 23rd that a research team led by Professor Park Chae-yong of its Department of Computer Science had developed “VR haptic navigation technology,” which measures changes in arm posture in real time and automatically corrects the direction of vibrations.
Existing VR devices used vibrations from wearable bands or controllers to guide users. But when users changed posture by raising or bending their arms inward, their sense of direction felt through the skin could become misaligned, often causing them to take the wrong path. This is because as the angle of the arm changes, the body’s perceived reference direction changes as well.
The research team first analyzed how people perceive vibration stimuli as they move their arms at different angles. Based on this, it developed a perceptual model that automatically corrects the direction indicated by vibrations without error, even as the arm moves.
The technology’s effectiveness was also demonstrated in validation experiments conducted in a real VR environment. Participants moved their arms at various angles without looking at the screen and accurately found the route they had originally intended using only their sense of vibration.
The technology enables users to find their way using only the sensations in their hands and arms, without having to look at a complex screen. It is expected to be used in various fields, including VR games and virtual training to enhance immersion, as well as safe navigation devices for people with visual impairments.
The research received the Best Paper Award at IEEE ISMAR 2026, the world’s most prestigious conference in the field of mixed and virtual reality. Hwang Jae-hyeong, a student in an integrated master’s and doctoral program, was the first author, and Jin Hye-seong, a student in an integrated bachelor’s, master’s and doctoral program, was a co-author. The related paper is scheduled to be published in the international journal IEEE TVCG.
