Interface device between machine and operator uses modification of characteristics of variable force which machine exerts on operator

摘要

The device communicates with the user by using an intermediate variable force which acts through a body having parts designed to modify its center of gravity. The device includes a tube envelope (102) and a balance weight (101), which moves inside the tube (102) and represents the mass of the device. There is a mechanism which displaces the weight (101) inside the tube (102). There is also a system designed to control the position of the weight (101) in a reference linked to the device. Additionally there is an electronic command and control interface. The device may contain several movable weights and several displacement mechanisms which independently displace the weights.
