Method and apparatus for biometric control of display indicator
View Patent ↗Biometric sensors such as electromyographic sensors 21 A and 21 B sense muscle flexing. The resultant signals are sensed 11 and utilized to establish 13 a corresponding angle of movement and to establish 15 magnitude of movement for an on-screen display indicator such as an on-screen cursor 61. In one embodiment, the electromyographic sensor signals are shifted and scaled 31. Wireless transmissions can be utilized to increase portability of the sensor interface.
1. A method for manipulating an on-screen cursor comprising:
sensing first electromyogram signals;
sensing second electromyogram signals;
in response to sensing at least some of the first electromyogram signals, establishing an angle of directional movement for the on-screen cursor;
in response to sensing at least some of the second electromyogram signals, moving the on-screen cursor in a previously determined direction.
2. The method of claim 1 wherein sensing first electromyogram signals includes sensing first electromyogram signals from at least a first muscle and wherein sensing the second electromyogram signals includes sensing second electromyogram signals from at least a second muscle, which second muscle is different from the first muscle.
3. The method of claim 1 wherein establishing an angle of directional movement for the on-screen cursor includes rotating an on-screen directional indicator that corresponds to the angle of directional movement.
4. The method of claim 3 wherein rotating an on-screen directional indicator that corresponds to the angle of directional movement includes rotating the on-screen cursor.
5. The method of claim 1 and further comprising wirelessly transmitting information signals that at least correspond to the first and second electromyogram signals.
6. The method of claim 1 and further comprising wirelessly transmitting information signals that at least correspond to the angle of directional movement for the on-screen cursor and movement of the on-screen cursor in a previously determined direction.
7. The method of claim 1 and further comprising processing the first and second electromyogram signals to at least level shift the first and second electromyogram signals.
8. The method of claim 1 and further comprising processing the first and second electromyogram signals to at least scale the first and second electromyogram signals.
9. The method of claim 1 and further comprising processing the first and second electromyogram signals to at least level shift and scale the first and second electromyogram signals.
10. The method of claim 1 and further comprising, in response to sensing at least one of the electromyogram signals, asserting a mouse click.
11. The method of claim 10 wherein asserting a mouse click includes asserting a mouse left click.
12. The method of claim 10 wherein asserting a mouse click includes asserting a mouse right click.
13. The method of claim 1 wherein sensing first electromyogram signals includes sensing first electromyogram signals that at least equal a predetermined threshold.
14. A method for manipulating an on-screen cursor comprising:
in response to receiving a first biometric signal, deriving corresponding angular direction of movement information for the on-screen cursor;
in response to receiving a second biometric signal, deriving corresponding magnitude of movement information for the on-screen cursor.
15. The method of claim 14 and further comprising, in response to receiving at least one of the first and second biometric signals, deriving a corresponding mouse click assertion.
