A man-machine interface is disclosed which provides force, texture, pressure and temperature information to sensing body parts. The interface is comprised of a force-generating device (900) that produces a force which is transmitted to a force-applying device (902) via force-transmitting means (908)....http://www.google.es/patents/US6059506?utm_source=gb-gplus-sharePatente US6059506 - Force feedback and texture simulating interface device
