Neck strap haptics: an algorithm for non-visible VR information using haptic perception on the neck

In this poster, we propose a new haptic rendering algorithm that dynamically modulates wave parameters to convey distance, direction, and object type by utilizing neck perception and the Hapbeat-Duo, a haptic device composed of two actuators linked by a neck strap. This method is useful for various VR use cases because it provides feedback without disturbing users' movement. In our experiment, we presented haptic feedback of sine waves which were dynamically modulated according to direction and distance between a player and a target. These waves were presented to both sides of the users' necks independently. As a result, players could reach invisible targets and immediately know they had reached the targets. The proposed algorithm allows the neck to become as important a receptive part of body as eyes, ears, and hands.
