US Patent 7098776 Methods and apparatus for vibrotactile communication

A device for enhancing interpersonal communication over distance through use of touch. A vibrotactile (touch-and-vibration) interface is used to improve existing remote communication by allowing tactile cues to augment the audio-visual information in real-time. The pressure exerted by each finger of the transmitter produces patterns of vibration against the corresponding finger of the receiver. A hand-held device using the interface allows a user to transmit and receive patterns of vibration to and from a remote user and signify tactile gestures, or expressive uses of touch.
