Abstract

Disclosed are methods, systems, and computer program products for receiving input from a multi-function momentary switch by providing feedback from a user interface for each function associated with the switch. According to one method, alphanumeric input values are associated with a momentary switch. Each of the alphanumeric input values is associated with a different active time duration for the switch and at least two of the alphanumeric input values are associated with a same alphanumeric text entry mode. A duration of time the switch is in the active state is monitored. At least one of tactile and audible feedback is provided each time the duration of time matches a duration associated with an alphanumeric input value. The alphanumeric input value associated with the alphanumeric text entry mode and duration for the last feedback provided is selected as input from the switch.

determining when the switch transitions from the inactive state to the active state;

in response to determining that the switch transitioned from the inactive state to the active state, monitoring a duration that the switch is in the active state;

providing at least one of tactile and audible feedback each time the duration matches an active time duration associated with an alphanumeric input value;

determining when the switch transitions from the active state to the inactive state; and

in response to determining that the switch transitioned from the active state to the inactive state, selecting as input from the switch the alphanumeric input value associated with the alphanumeric text entry mode and the duration for the last feedback provided.

2. The method of claim 1 comprising associating a plurality of audio feedback values with the switch, wherein each of the plurality of audio feedback values is associated with a different active time duration for the switch and wherein at least one of the plurality of audio feedback values is used to provide the audible feedback.

3. The method of claim 1 wherein providing the at least one of tactile and audible feedback includes providing the audible feedback using a speaker.

4. The method of claim 1 wherein providing the at least one of tactile and audible feedback includes providing the audible feedback using a buzzer.

5. The method of claim 1 comprising associating a plurality of tactile feedback values with the switch, wherein each of the plurality of tactile feedback values is associated with a different active time duration for the switch and wherein at least one of the plurality of tactile feedback values is used to provide the tactile feedback.

6. The method of claim 1 wherein providing the at least one of tactile and audible feedback includes providing the tactile feedback using an electromechanical transducer.

7. The method of claim 1 wherein providing the at least one of tactile and audible feedback includes providing the tactile feedback using a mechanical resonator.

8. The method of claim 1 comprising debouncing the switch to reduce second-incident switching.

9. The method of claim 1 wherein monitoring a duration that the switch is in the active state includes setting a timer in response to determining that the switch transitioned from the inactive state to the active state.

10. The method of claim 9 comprising clearing the timer in response to determining that the switch transitioned from the active state to the inactive state.

11. A system for receiving input from a multiple-function momentary switch by providing feedback from a user interface for each function associated with the switch, the system comprising:
