First Claim
1. A device for producing a signal at a sensing body part simulating the interaction between an interactive entity and a virtual or physical object, said device comprising:
- means for generating a force simulating the interaction between said interactive entity and said object; and
at least one of;
(a) means for applying said generated force between said sensing body part and a second body part which serves as a non-sensing part;
(b) means for applying said generated force to said sensing body part, said applying means comprising an entity displaced from said sensing body part in a first unactivated position and touching said sensing body part in a second activated position; and

Abstract
A man-machine interface is disclosed which provides force and texture information to sensing body parts. The interface is comprised of a force actuating device that produces a force which is transmitted to a force applying device. The force applying device applies the generated force to a pressure sensing body part. A force sensor on the force applying device measures the actual force applied to the pressure sensing body part, while angle sensors measure the angles of relevant joint body parts. A computing device uses the joint body part position information to determine a desired force value to be applied to the pressure sensing body part. The computing device combines the joint body part position information with the force sensor information to calculate the force command which is sent to the force actuating device. In this manner, the computing device may control the actual force applied to a pressure sensing body part to a desired force which depends upon the positions of related joint body parts. In addition, the interface is comprised of a displacement actuating device which produces a displacement which is transmitted to a displacement applying device (e.g., a texture simulator). The displacement applying device applies the generated displacement to a pressure sensing body part. The force applying device and displacement applying device may be combined to simultaneously provide force and displacement information to a pressure sensing body part.
