Abstract

The present invention discloses a system and method for motion recognition and control of a prosthetic device. The system of the present invention uses a movement detector for detecting dimensional motion of a non-disabled physical appendage and generating motion information based on this detecting. The system further includes a microcontroller adapted to be connected to the movement detector for receiving and processing the motion information transmitted from the one or more movement detectors. The system controls a prosthetic device which has actuators that are configured to actuate motion of the prosthetic device based on the processing of the motion information.

First claim

The invention claimed is:

1. A system for motion recognition and non-invasive control of a prosthetic device, the system comprising:
a movement detector on the prosthetic device for detecting multi-dimensional motion of a non-disabled physical appendage and generating motion information based on said detecting;
a microcontroller connected to said movement detector for receiving and processing the motion information transmitted from the movement detector;
the prosthetic device, connected to the microcontroller, wherein the prosthetic device comprises one or more actuators which are configured to actuate motion of the prosthetic device, based on said processing of the motion information;

wherein an authentication component collects data associated with characteristics of the non-disabled physical appendage and stores the characteristics in a memory, and determines whether the multi-dimensional motion detected by the movement detector matches characteristics of the non-disabled physical appendage collected and stored in the memory, as a condition of processing the motion information by the microcontroller.

2. The system of claim 1 , wherein the movement detector comprises one or more sensors, wherein the one or more sensors comprise at least one motion sensor and at least one optical sensor.

3. The system of claim 2 , wherein the one or more sensors comprise a depth sensor, wherein the depth sensor comprises at least one of, an accelerometer, a gyroscope, a magnetometer and an e-compass.

4. The system of claim 2 , wherein the at least one optical sensor comprises one or more cameras, wherein the one or more cameras are RGB or monochrome cameras, or a combination thereof.

5. The system of claim 1 , wherein processing the motion information comprises converting the motion information to movement commands readable by the one or more actuators.

6. The system of claim 1 , wherein the processing motion information comprises mimicking a motion detected by the movement detector, wherein the motion is performed by the non-disabled physical appendage.

7. The system of claim 1 , wherein the prosthetic device is configured to mimic the multi-dimensional motion detected from the non-disabled physical appendage in real-time.

8. The system of claim 1 , further comprising a memory component, configured to store three dimensional positional data and movement patterns obtained from the movement detector.

9. The system of claim 8 , wherein the microcontroller is preprogrammed with obstacle detection and avoidance capabilities, wherein if an obstacle is detected, movement instructed to the actuators is terminated, and/or an alternate path stored in the memory component is instructed by the microcontroller.

10. The system of claim 1 , wherein the non-disabled physical appendage and the prosthetic device do not correspond to a same body part.

11. The system of claim 1 , wherein the authentication component is connected to the microcontroller and comprises a processor and a memory for storing authentication data associated with a user of the prosthetic device.

12. The system of claim 1 , wherein the authentication component is an input/output unit.

13. The system of claim 1 , wherein the authentication component is a biometric authentication means.

14. A method for motion recognition and non-invasive movement control of a prosthetic device, the method comprising:
detecting a movement conducted by a non-disabled physical appendage using a sensor on the prosthetic device;
transmitting said detected movement to a microcontroller;
processing motion information based on the transmitted detected movement and actuating motion of the prosthetic device based on the processed motion information;

storing motion patterns conducted by the non-disabled appendage in a memory component for use in actuating movement in the prosthetic device at any time by a user of the prosthetic device; and
authenticating the user by determining whether the detected movement matches the stored motion patterns of the non-disabled physical appendage and actuating motion of the prosthetic device only if it is the case.

15. The method of claim 14 , wherein the step of detecting a movement is conducted by a movement detector, wherein the movement detector comprises one or more motion sensors and one or more optical sensors.

16. The method of claim 14 , wherein processing the motion information comprises converting the motion information to movement commands readable by one or more actuators.

17. The method of claim 15 , wherein the processing motion information comprises mimicking a motion detected by the movement detector, wherein mimicking the motion detected is actuated by the prosthetic device in real-time.

18. The method of claim 14 , wherein the prosthetic device is configured to mimic an identical motion performed by the non-disabled physical appendage.

19. The method of claim 14 , further comprising detecting obstacles and carrying out obstacle avoidance commands, wherein if an obstacle is detected the movement of actuators is terminated, and/or an alternate movement path is instructed by the microcontroller.

20. The method of claim 14 , wherein authenticating the user further comprises authenticating biometric data of the non-disabled appendage.
