Abstract

Methods, devices, systems, and apparatus, including computer programs encoded on a computer storage medium, for brain-controlled body movement assistance devices. In one aspect, a device includes a brain-controlled body movement assistance device with a brain-computer interface (BCI) component adapted to be mounted to a user, a body movement assistance component operably connected to the BCI component and adapted to be worn by the user, and a feedback mechanism provided in connection with at least one of the BCI component and the body movement assistance component, the feedback mechanism being configured to output information relating to a usage session of the brain-controlled body movement assistance device.

Claims (24)

1. A brain-controlled body movement assistance system comprising:

a brain-computer interface (BCI) component configured to be worn on a forearm of a user and to (i) receive brain signal information captured from a user, (ii) process the captured brain signal information to detect an intended body movement of the user, and (iii) produce an output signal corresponding to the intended body movement;

a body movement assistance component operably connected to the BCI component and adapted to be worn by the user, the body movement assistance component configured to receive the output signal from the BCI component and, in response thereto, impart movement in a manner corresponding to the intended body movement; and

a feedback mechanism connected with at least one of the BCI component and the body movement assistance component, the feedback mechanism configured to output information regarding the brain-controlled body movement assistance device.

2. The system of claim 1 , wherein the body movement assistance component is adapted to be worn by and connect to a hand of the user.

3. The system of claim 2 , wherein the body movement assistance component includes a first extension member to which a first finger attachment mechanism is slidably attached.

4. The system of claim 3 , wherein the first extension member is movable in a first direction that is downward in relation to a top of a first attached finger to provide flexion movement of the first attached finger and adapted to be moved in an opposite, second direction that is upward in relation to the top of the first attached finger to provide extension movement of the first attached finger.

5. The system of claim 4 , wherein the body movement assistance component includes a second extension member to which a second finger attachment mechanism is slidably attached.

6. The system of claim 5 , wherein the second extension member is movable in the first direction that is downward in relation to a top of a second attached finger to provide flexion movement of the second attached finger and adapted to be moved in the opposite, second direction that is upward in relation to the top of the second attached finger to provide extension movement of the second attached finger.

7. The system of claim 5 , wherein the first finger attachment mechanism is adapted to allow rocking of the first finger attachment mechanism with respect to the first extension member, and wherein the second finger attachment mechanism is adapted to allow rocking of the second finger attachment mechanism with respect to the second extension member.

8. The system of claim 2 , wherein the BCI component comprises a housing attached to the body movement assistance component, the housing adapted to be worn by and connect to the forearm of the user.

9. The system of claim 8 , wherein the BCI component is disposed within the housing.

10. The system of claim 1 , wherein the feedback mechanism comprises an audio output device.

11. The system of claim 1 , wherein the feedback mechanism comprises a visual output device.

12. The system of claim 11 , wherein the visual output device comprises one or more indicator lights.

13. The system of claim 11 , wherein the visual output device comprises a display device.

14. The system of claim 13 , further comprising a housing attached to the body movement assistance component and adapted to be worn by and connect to the forearm of the user, wherein at least a portion of the BCI component is disposed within the housing and the display device is attached to the housing.

15. The system of claim 1 , further comprising one or more sensors arranged to detect a level of force to which the user drives movement of the body movement assistance component.

16. A brain-controlled body movement assistance system, comprising:

a brain-computer interface (BCI) component configured to be worn on an arm of a user and to (i) receive brain signal information captured from the user, (ii) detect, after processing the received brain signal information, an intention to move a body part, and (iii) output a signal corresponding to the intention to move the body part; and

a body movement assistance component configured to receive the signal from the BCI component, and to be worn by the user and to move in a manner that imparts movement to the body part, wherein the user is able to ambulate while wearing the body movement assistance component.

17. The system of claim 16 , further comprising a feedback mechanism configured to provide information indicative of the intention to move the body part.

18. The system of claim 16 , wherein the body movement assistance component is operably connected to the BCI component and adapted to be worn on a hand of the user.

19. The system of claim 16 , further comprising means for generating one or more sensory stimulations to prompt the user to generate one or more particular brain signals.
