Mark R Tremblay, Mark H Yim: Tactile feedback man-machine interface device. Virtual Technologies, Flehr Hohbach Test Albritton & Herbert, July 11, 2000: US06088017 (193 worldwide citation)

A man-machine interface which provides tactile feedback to various sensing body parts is disclosed. The device employs one or more vibrotactile units, where each unit comprises a mass and a mass-moving actuator. As the mass is accelerated by the mass-moving actuator, the entire vibrotactile unit vib ...
