Abstract

A method and apparatus for processing a set of communicated signals associated with a set of muscles, such as the muscles near the larynx of the person, or any other muscles the person use to achieve a desired response. The method may include attaching a sensor near an area of a user'"'"'s body associated with speech production, detecting an electrical signal from the user'"'"'s nervous system through the sensor, and processing the detected electrical signal to provide communication capability for the user. The processing may include extracting a set of features of the detected electrical signal. The extracted set of features may be compared with a set of prototype features. The set of prototype features may correspond to at least one of multiple response classes. The multiple response classes may include an affirmative response class and a negative response class.

Claims

1-15. -15. (canceled)

16. A method of processing a set of communicated signals, said method comprising:

attaching a sensor near an area of a user'"'"'s body associated with speech production;

detecting an electrical signal from the user'"'"'s nervous system through the sensor; and

processing the detected electrical signal to provide communication capability for the user.

17. The method of claim 16, wherein the processing comprises extracting a set of features of the detected electrical signal.

18. The method of claim 17, comprising comparing the extracted set of features with a set of prototype features.

19. The method of claim 18, wherein the set of prototype features corresponds to at least one of multiple response classes.

20. The method of claim 19, wherein the multiple response classes comprise an affirmative response class and a negative response class.

21. The method of claim 16, wherein the area of the user'"'"'s body associated with speech production is the user'"'"'s brain.

22. The method of claim 18, further comprising:

selecting a prototype from the set of prototype features with a minimum difference between the prototype feature and the set of features of the signal.

23. The method of claim 22, further comprising:

controlling a computing device using a command associated with the prototype.

24. The method of claim 22, further comprising:

controlling an electronic communication device using a command associated with the prototype.

25. The method of claim 16, further comprising:

wirelessly transmitting the electrical signal to a signal processing unit.

26. An apparatus for processing a set of communicated signals comprising:

a sensor configurable to be attached near an area of a user'"'"'s body associated with speech production;

an electrode configurable to detect an electrical signal from the user'"'"'s nervous system through the sensor; and

a processor configurable to process the electrical signal to provide communication capability for the user.

27. The apparatus of claim 26, wherein the processor comprises an extraction processor configurable to extract a set of features from the detected electrical signal.

28. The apparatus of claim 27, wherein the classification processor is configurable to compare the extracted features with a set of prototype features, wherein the set of prototype features corresponds to at least one of multiple response classes.

29. The apparatus of claim 27, wherein the multiple response classes include an affirmative response class and a negative response class.

30. The apparatus of claim 26, wherein the area of the user'"'"'s body associated with speech production is the user'"'"'s brain.

31. The apparatus of claim 28, further comprising:

a comparator configurable to select a prototype feature of the set of prototype features with the smallest relative difference.

32. The apparatus of claim 31, wherein a command associated with the prototype is configurable to control a computing device.

33. The apparatus of claim 31, wherein a command associated with the prototype is configurable to control an electronic communication device.

34. The apparatus of claim 26, further comprising:

an analog to digital converter disposed within the sensor and configurable to convert the detected electrical signal into an equivalent digital signal.

35. The apparatus of claim 34, further comprising:

a wireless transmitter configurable to wirelessly transmit the digital signal to a signal processing unit.
