Abstract

Systems and methods for manual gesture recognition to control prosthetic devices. Low encumbrance systems utilizing glove-based recognition to control prosthetic devices. Prosthetic control systems and methods are also provided utilizing elements for application on the user's fingernails.

First claim

What is claimed is:

1. A system, comprising:
a signal element configured to generate a signal;
a fingernail mount configured to secure the signal element on a fingernail of a first finger of a user such that the signal element remains on the fingernail of the first finger of the user while the user performs a gesture; and
a detection element configured for disposal on a second finger of a user, and configured to detect a signal generated by the signal element, wherein the signal indicates that the user has performed the gesture using the first finger and the second finger of the user;
wherein the detection element comprises a circuit configured to distinguish the signal from the signal element from a plurality of other signals from other signal elements disposed on a plurality of other fingers of the user; and
wherein the circuit is configured to distinguish the signal from the signal element from the plurality of other signals from the other signal elements by measuring signal intensity of the signal element as acquired by a combination of antennas and determining a position of the signal element relative to a plane of a palm of the user.

2. The system according to claim 1 , wherein the detection element is further configured to detect a characteristic of the signal, the characteristic of the signal indicative of a characteristic of the gesture.

3. The system according to claim 2 , wherein the characteristic of the signal comprises an RFID tag ID, and wherein the detection element is configured to distinguish the first finger from a plurality of other fingers based on the RIFD tag ID.

4. The system according to claim 2 , wherein the characteristic of the signal comprises a signal intensity, strength, phase, or amplitude, or change therein.

5. The system according to claim 2 , wherein the characteristic of the signal comprises a resonant frequency of a circuit transmitting or generating the signal.

6. The system according to claim 2 , wherein the characteristic of the signal comprises a frequency of the signal.

7. The system according to claim 1 , wherein the signal element comprises an RFID tag, and wherein the detection element comprises an RFID antenna.

8. The system according to claim 1 , wherein the signal element comprises an LC circuit.

9. The system according to claim 1 , wherein the signal element comprises a resonator and the receiver element is configured to distinguish the signal element based on a resonance frequency.

10. The system according to claim 9 , wherein the resonator comprises an LC tank circuit.

11. The system according to claim 9 , wherein the resonator comprises an RFID circuit.

12. The system according to claim 9 , wherein the resonator comprises a microcontroller circuit configured to respond with a specified signal unique to the user's first finger or second finger.

13. The system according to claim 1 , wherein the signal indicates that a sign language gesture has been performed using at least the first finger and the second finger of the user.

14. A system. comprising:
a signal element configured to generate a signal;
a fingernail mount configured to secure the signal element on a fingernail of a first finger of a user such that the signal element remains on the fingernail of the first finger of the user while the user performs a gesture;
a detection element configured for disposal on a second finger of a user, and configured to detect a signal generated by the signal element, wherein the signal indicates that the user has performed the gesture using the first finger and the second finger of the user; and
a controller configured to control a prosthetic device based on the signal detected by the detection element.

15. The system according to claim 14 , wherein the control of the prosthetic device causes the prosthetic device to perform an action or a movement corresponding to the gesture.
