Time windows for sensor input
View Patent ↗An apparatus includes timing circuitry configured to initiate a timing window in response to input sensed by an optical sensor, association circuitry configured to associate the input with additional input sensed by a different optical sensor if the additional input commences during the timing window and filter circuitry configured to filter out additional input sensed by a different optical sensor if the additional input commences after expiration of the timing window and prior to a subsequent initiation of the timing window. Various other apparatuses, systems, methods, etc., are also disclosed.
1. An apparatus comprising:
timing circuitry that initiates a timing window in response to input sensed by an optical sensor that comprises a dominant status wherein the timing circuitry comprises circuitry that times a duration of the input sensed by the optical sensor;
reset circuitry that resets the timing circuitry in response to a reset trigger wherein the reset allows for re-initiation of the timing window and wherein the reset trigger comprises a trigger based on an amount of received input sensed by the optical sensor after expiration of the timing window;
association circuitry that associates the input with additional input sensed by a different optical sensor if the additional input commences during the timing window wherein the different optical sensor comprises a nondominant status; and
filter circuitry that filters out additional input sensed by the different optical sensor if the additional input commences after expiration of the timing window and prior to a subsequent initiation of the timing window.
2. The apparatus of claim 1 wherein the timing circuitry comprises circuitry that initiates the timing window only if the duration of the input sensed by the optical sensor exceeds a predetermined duration.
3. The apparatus of claim 1 wherein the timing circuitry comprises circuitry that shifts the timing window in time based at least in part on the duration of the input sensed by the optical sensor.
4. The apparatus of claim 1 further comprising circuitry to call for rendering of a graphic to a display that indicates that the filter circuitry filtered out the additional input.
5. The apparatus of claim 1 wherein the association of the input with the additional input depends on status of the optical sensor in relationship to status of the different optical sensor.
6. The apparatus of claim 1 wherein the optical sensors comprise at least one optical sensor disposed adjacent at least one key of a computer keyboard.
7. The apparatus of claim 1 wherein, as to the reset trigger, the amount of received input sensed by the optical sensor after expiration of the timing window comprises no received input for a predetermined period of time.
8. A method comprising:
receiving input from an optical sensor that comprises a dominant status;
timing a duration of the receiving input from the optical sensor;
initiating a timing window responsive to the receiving input from the optical sensor;
after expiration of the timing window, receiving additional input from a different optical sensor that comprises a nondominant status;
filtering out the additional input; and
after expiration of the timing window, allowing for re-initiation of the timing window responsive to a reset trigger based on an amount of received input sensed by the optical sensor and, after allowing for re-initiation of the timing window, reinitiating the timing window responsive to subsequently receiving input from the optical sensor.
9. The method of claim 8 further comprising, after the reinitiating, subsequently receiving additional input from the different optical sensor during the reinitiated timing window.
10. The method of claim 9 further comprising associating the subsequently received input and the subsequently received additional input and issuing a command based at least in part on the associating.
11. The method of claim 8 wherein the initiating comprises initiating the timing window only if the duration of the receiving input from the optical sensor exceeds a predetermined value.
12. The method of claim 8 further comprising rendering a graphic to a display to indicate filtering out of the additional input.
13. The method of claim 8 further comprising rendering a graphic to a display to indicate pendency of the timing window.
14. The method of claim 8 wherein, as to the reset trigger, the amount of received input sensed by the optical sensor comprises no received input for a predetermined period of time.
15. One or more non-transitory computer-readable storage media comprising computer-executable instructions to instruct a computer, the instructions comprising instructions to:
assign a dominant status to one of two sensors and a nondominant status to the other of the two sensors;
time a duration of input sensed by the sensor with the dominant status;
initiate a timing window in response to input sensed by the sensor with the dominant status;
associate the input with additional input sensed by the sensor with the nondominant status if the additional input commences during the timing window;
filter out additional input sensed by the sensor with the nondominant status if the additional input commences after expiration of the timing window and prior to a re-initiation of the timing window; and
after expiration of the timing window, allow for the re-initiation of the timing window responsive to a reset trigger based on an amount of received input sensed by the sensor with the dominant status.
16. The one or more non-transitory computer-readable storage media of claim 15 further comprising instructions to initiate a timing window only if the duration exceeds a predetermined duration.
17. The one or more non-transitory computer-readable storage media of claim 15 wherein, as to the reset trigger, the amount of received input sensed by the sensor with the dominant status comprises no received input for a predetermined period of time.
