Abstract
A device includes a touch-sensitive display having a first location associated with a first threshold and a second location associated with a second threshold. A sensor is configured to detect depression of the touch-sensitive display by detecting a force exerted at a location on the touch-sensitive display The force exerted effects a characteristic of an optical signal. The characteristic is compared to the first threshold when the force is exerted in the first location, and the characteristic is compared to the second threshold when the force is exerted in the second location.
Claims13
A device comprising:
- a touch-sensitive display having a first location associated with a first threshold and a second location associated with a second threshold;
- a sensor configured to detect depression of the touch-sensitive display by detecting a force exerted at a location on the touch-sensitive display, wherein the force exerted effects a characteristic of an optical signal, wherein the characteristic is compared to the first threshold when the force is exerted in the first location, and wherein the characteristic is compared to the second threshold when the force is exerted in the second location.
A method comprising:
- detecting a touch at a first location on a touch-sensitive display;
- associating one of a first threshold and a second threshold with the location of the touch;
- emitting an optical signal toward the touch-sensitive display;
- determining a phase difference between two samples of the optical signal;
- when the phase difference meets the threshold, processing the touch as a selection.
