Abstract
A controller is formed as an array of transmitting antennas and receiving antennas that are placed on the skin of a user so that the underlying movement of the user's skin can be measured by the interaction of the transmitting antennas and the receiving antennas. In an embodiment, the transmitting antennas and receiving antennas are located in an area proximate to the wrist. The movement of the transmitting antennas and subsequent measurement of signals received by receiving antennas are used in order to determine position and pose of the hand and its digits.
Claims20
An apparatus comprising:
- a plurality of transmitting antennas adapted to be placed on a body part, wherein each of the plurality of transmitting antennas generates a unique frequency orthogonal signal;
- a plurality of receiving antennas adapted to placed on the body part, wherein the plurality of receiving antennas are adapted to receive the unique frequency orthogonal signals,
- wherein when the plurality of transmitting antennas and the plurality of receiving antennas are placed on the body part movement of skin of the body part causes the plurality of transmitting antennas and the plurality of receiving antennas to move with respect to each other;
- and
- wherein measurements of the unique frequency orthogonal signals received by at least one of the plurality of receiving antennas are used to provide measurements regarding movement of the skin of the body part.

An apparatus comprising:
- a substrate;
- a transmitting antenna adapted to placed on the substrate,
- a plurality of receiving antennas adapted to placed on the substrate, wherein the receiving antennas are adapted to receive signals transmitted from the transmitting antenna,
- wherein when the substrate is placed on a body part movement of skin of the body part causes the transmitting antenna and the plurality of receiving antennas to move with respect to each other;
- and
- wherein measurements of signals received by at least one of the plurality of receiving antennas are used to provide measurements regarding movement of the skin of the body part.
