We applied phantom sensation and sensory saltation to generate spatial and directional information using a hand-held device providing vibrotactile cues, T-hive. A sphere-shape is applied to the handle of the T-Hive for comfortable gripping, and the input part can provide six degrees of freedom of motion for the handle. To maintain isolation among vibrotactile actuators, the surface of the sphere is divided into several pieces. Each vibrating module consists of a vibration motor, a section of sphere surface, and a vibration isolator. As an evaluation of the developed device, two experiments were conducted to test whether phantom sensation is applicable to the entire hand uniformly. Our results show that the phantom sensation occurs whole hand uniformly. Also, spatial and directional information is useful for displaying intuitive information for object control with vibrotactile feedback.
