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). The force-applying device applies the
generated force to a sensing body part A force sensor (909) associated
with the force-applying device measures the actual force applied to the
sensing body part, while angle sensors (9171 measure the angles of
relevant joint body parts. A computing device (911) uses the joint body
part position information to determine a desired force value to be
applied to the 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-generating device.
In this manner, the computing device may control the actual force applied
to a sewing body part to a desired force which depends upon the positions
of related body parts. In addition, the interface is comprised of a
displacement-generating device (901) which produces a displacement which
is transmitted to a displacement-applying device (902) (e.g., a texture
simulator) via displacement-generating means (920). The
displacement-applying device applies the generated displacement to a
sensing body part. The force-applying device and displacement-applying
device may be combined to simultaneously provide force and displacement
information to a sensing body part. Furthermore, pressure and
temperature-applying devices may be combined to also provide pressure and
temperature sensations to a sensing body part. In addition, a
force-applying device may be attached to a sensing body part and apply
force to the sensing body part, where the force is applied relative to a
reference location not rigidly affixed to the living body.
