19 A New Mobile Haptic Game for Dynamic Objects

This paper presents a mobile games prototype where a user haptically senses the dynamic behavior of a virtual object with vibrotactile information. To haptically simulate the behavior of the movement of a target object, we adjust the activation delay time of two vibration motors and overlap each vibration signals which is are generated from two vibration motors. We constructed a mobile test bed system and investigated whether our game system haptically simulates the movement of the object. The experiment clearly verifies that the proposed system efficiently describes an object’s direction and its movement though vibrotactile information.
