SENSING KEY PRESS ACTIVATION
Embodiments generally relate to sensing key press activation. In one embodiment, a method includes providing a signal in an electronic device. The method further includes causing the signal to reflect off of a key of the electronic device. The method further includes determining a movement of the key based on a reflection of the signal.
1 . A method comprising:
providing a signal in an electronic device;
causing the signal to reflect off of a key of the electronic device; and
determining a movement of the key based on a reflection of the signal.
2 . The method of claim 1 , further comprising causing the signal to pass through a channel.
3 . The method of claim 1 , further comprising enabling a sensor to detect the signal based on a position of the key.
4 . The method of claim 1 , wherein the determining of the movement of the key comprises detecting the signal at a sensor, and wherein the signal is detected at the sensor when the key is in at least a first state.
5 . The method of claim 1 , wherein the determining of the movement of the key comprises detecting the signal at a sensor, wherein the signal is detected at the sensor when the key is in at least a first state, and wherein the first state is a pressed state.
6 . The method of claim 1 , wherein the electronic device is a music device.
7 . The method of claim 1 , wherein the electronic device comprises a keyboard having a plurality of keys, and wherein the method comprises determining the movement of two or more of the keys based on reflections of signals.
8 . A system comprising:
one or more processors; and
logic encoded in one or more tangible media for execution by the one or more processors, and when executed operable to perform operations comprising:
providing a signal in an electronic device;
causing the signal to reflect off of a key of the electronic device; and
determining a movement of the key based on a reflection of the signal.
9 . The system of claim 8 , wherein the logic when executed is further operable to perform operations comprising causing the signal to pass through a channel.
10 . The system of claim 8 , wherein the logic when executed is further operable to perform operations comprising enabling a sensor to detect the signal based on a position of the key.
11 . The system of claim 8 , wherein, to determine the movement of the key, the logic when executed is further operable to perform operations comprising detecting the signal at a sensor, and wherein the signal is detected at the sensor when the key is in at least a first state.
12 . The system of claim 8 , wherein, to determine the movement of the key, the logic when executed is further operable to perform operations comprising detecting the signal at a sensor, wherein the signal is detected at the sensor when the key is in at least a first state, and wherein the first state is a pressed state.
13 . The system of claim 8 , wherein the electronic device is a music device.
14 . The system of claim 8 , wherein the electronic device comprises a keyboard having a plurality of keys, and wherein the logic when executed is further operable to perform operations comprising determining the movement of two or more of the keys based on reflections of signals.
15 . An electronic device comprising:
an emitter that provides a signal in the electronic device, wherein the signal reflects off of a key of the electronic device; and
a processor that determines a movement of the key based on a reflection of the signal.
16 . The electronic device of claim 15 , further comprising a channel through which the signal passes.
17 . The electronic device of claim 15 , further comprising a sensor that detects the signal based on a position of the key.
18 . The electronic device of claim 15 , further comprising a sensor that detects the signal when the key is in at least a first state.
19 . The electronic device of claim 15 , further comprising a sensor that detects the signal when the key is in at least a first state, wherein the first state is a pressed state.
20 . The electronic device of claim 15 , wherein the electronic device is a music device.
