Abstract

Systems and methods as described the present disclosure are capable of generating haptic feedback in response to sensing a biological signal from a vertebrate. A method according to one embodiment, among others, includes detecting a neural signal from a vertebrate. The method also includes generating a haptic effect on the vertebrate corresponding to the neural signal.

Claims

1. An apparatus comprising:

a sensor configured to sense a neural signal from a human being;

a processing device in communication with the sensor, the processing device configured to receive a neural signal from the sensor and process the neural signal to generate a first signal;

a computer application configured to respond to the first signal and to generate a first haptic response signal as a result of an event within the computer application; and

a haptic device in communication with the computer application, the haptic device configured to receive the first haptic response signal and generate a first haptic effect on the human being.

2. The apparatus of claim 1, wherein the processing device is further configured to generate a second haptic response signal in response to receiving the neural signal, the haptic device further configured to receive the second haptic response signal and generate a second haptic effect on the human being, wherein the second haptic effect verifies to the human being when neural signals have been sensed.

3. The apparatus of claim 1, wherein each sensor and each haptic device is positioned adjacent to the skin of the human being.

4. The apparatus of claim 1, wherein the sensors detect neural activity from the central nervous system of the human being.

5. The apparatus of claim 1, wherein the sensors detect brain activity of the human being.

6. The apparatus of claim 1, further comprising a second sensor configured to detect one or more of a secondary set of inputs from the human being, the secondary set of inputs including eye movement, facial muscle movement, body muscle movement or contraction, breathing rate, and heart rate.

7. The apparatus of claim 1, wherein the haptic device applies a signal to the central nervous system of the human being to emulate the haptic effect.

8. The apparatus of claim 1, wherein the haptic device comprises one or more actuators, and the haptic effect is a vibrotactile effect.

9. A method comprising:

detecting a neural signal from a vertebrate; and

generating a haptic effect on the vertebrate corresponding to the neural signal.

10. The method of claim 9, wherein detecting the neural signal comprises detecting a plurality of neural signals from brain activity of the vertebrate.

11. The method of claim 9, wherein detecting the neural signal comprises emitting infrared radiation to detect blood flow.

12. The method of claim 9, further comprising:

detecting a secondary set of inputs from the vertebrate, the secondary set of inputs including at least one input selected from the group of inputs consisting of eye movement, body movement, muscle movement, and muscle contraction.

13. The method of claim 9, wherein actuating the haptic effect further comprises:

imposing a first haptic effect in response to the detection of the neural signal; and

imposing a second haptic effect in response to a detection of an event occurring in an external device controlled by the neural signal.

14. The method of claim 9, wherein generating the haptic effect comprises at least one of applying a vibration to the vertebrate with an actuator and applying an electrical output to one or more portions of the body of the vertebrate.

15. The method of claim 9, further comprising:

sensing a second neural signal from the vertebrate based on the vertebrate'"'"'s response to the haptic effect; and

adjusting the haptic effect in response to the sensed second neural signal.

16. The method of claim 9, wherein the external device includes a computer and the detected event is associated with a location of a cursor within a graphical user interface of a computer application executed by the computer.

17. A system comprising:

means for sensing biological activity of a living organism;

means for processing the biological activity to generate a haptic response signal; and

means for rendering a haptic effect on the living organism, wherein the haptic effect is related to the haptic response signal generated by the processing means.

18. The system of claim 17, wherein the means for sensing biological activity includes means for sensing neural activity from the central nervous system of a human.

19. The system of claim 18, wherein the rendering means is configured to induce the haptic effect on the central nervous system of the human to mimic a sensation that occurs in reality.

20. The system of claim 17, further comprising:

means for interpreting the biological activity as a control signal to control an external electronic device.

21. The system of claim 20, wherein the means for rendering a haptic effect invokes a haptic effect based on an event occurring within the external electronic device.

22. A computer-readable medium adapted to store instructions that are executable by a processor, the stored instructions comprising logic configured to instruct the processor to:

detect a neural signal from a vertebrate; and

impose on the vertebrate a haptic effect corresponding to the neural signal.

23. The computer-readable medium of claim 22, wherein the stored instructions further comprise logic configured to instruct the processor, in response to the detected neural signal, to control a cursor or avatar in a computer program.

24. The computer-readable medium of claim 23, wherein the logic configured to instruct the processor to impose a haptic effect further comprises logic configured to instruct the processor to invoke a contraction of a muscle of the vertebrate to mimic the contraction of a virtual muscle of the avatar.

25. The computer-readable medium of claim 22, wherein the neural signal is related to brain activity.
