Abstract

The invention is directed to devices and methods for assisting individuals with poor extremity function (i.e., upper extremity function) to control devices. In one embodiment, a powered device is provided that comprises a controller and an orthosis communicably connected to the controller. An orthosis includes a harness worn by a user on a body part and a force sensing transducer positioned between the harness and the body part, wherein force applied to the transducer by the body part is communicated to the controller for controlling movement of the powered device. A method for controlling a device having a controller includes attaching a harness to a user'"'"'s body part and applying a force by the body part onto a force sensing transducer positioned between the harness and the body part, wherein the force is communicated to the controller for controlling the device.

Claims

1. A device, comprising:

a controller;

an orthosis communicably connected to the controller, the orthosis comprising;

a harness worn by a user on a body part; and

a force sensing transducer positioned between the harness and the body part, wherein a force applied to the transducer by the body part is communicated to the controller for controlling movement of the device.

2. The device of claim 1, wherein the device is a computer mouse.

3. The device of claim 2, wherein the body part is a foot.

4. The device of claim 1, wherein the orthosis is connected to the controller via a cable.

5. The device of claim 1, wherein the orthosis is connected to the controller wirelessly.

6. The device of claim 1, further comprising a cushion positioned between the force sensing transducer and the body part.

7. The orthosis of claim 1, wherein the body part is a foot.

8. The orthosis of claim 1, wherein the force is a pressure force.

9. An orthosis for controlling a device comprising a controller, the orthosis comprising:

a harness worn by a user on a body part; and

a force sensing transducer positioned between the harness and the body part, wherein a force applied to the transducer by the body part is communicated to the controller for controlling the device.

10. The orthosis of claim 9, wherein the device is a computer mouse.

11. The orthosis of claim 10, wherein the body part is a foot.

12. The orthosis of claim 9, wherein the force is a pressure force.

13. The orthosis of claim 9, wherein the body part is a foot.

14. The orthosis of claim 13, further comprising:

a first force sensing transducer positioned above a toe; and

a second force sensing transducer positioned below a toe.

15. The orthosis of claim 14, further comprising:

a third force sensing transducer positioned above a plurality of toes; and

a fourth force sensing transducer positioned below a plurality of toes.

16. The orthosis of claim 9, further comprising a cushion positioned between the force sensing transducer and the body part.

17. A method for controlling a device comprising a controller, the method comprising:

attaching a harness to a user'"'"'s body part; and

applying a force by the body part onto a force sensing transducer positioned between the harness and the body part, wherein the force is communicated to the controller for controlling the device.

18. The method of claim 17, wherein the device is a computer mouse.

19. The method of claim 18, wherein the user'"'"'s body part is a foot.

20. The method of claim 19, further comprising:

applying a first force by a first toe onto a first force sensing transducer; and

applying a second force by a second toe onto a second force sensing transducer;

wherein application of the first force and the second force result in different movements of the computer mouse.
