VibroTac: An ergonomic and versatile usable vibrotactile feedback device

This paper presents an ergonomic vibrotactile feedback device for the human arm. Due to the developed concept, the device can be used for a large spectrum of applications and a wide range of arm diameters since vibration segments are self-aligning to their intended positions. Furthermore, the device improves user convenience and movement capability as it is battery powered and controlled through a wireless communication interface. Vibrotactile stimuli are used to give collision feedback or guidance information to the human arm when interacting with a Virtual Reality scenario. The usefulness of this device has been shown in a Virtual Reality automotive assembly verification and a telerobotic system.
