Force Touch Button Emulation

摘要

Disclosed herein is an electronic device having a force sensing device. The force sensing device receives a continuous force input which is translated into a discrete event. In order to more accurately determine when the discrete event is to occur, the electronic device includes a two low-pass filters that concurrently receive a force signal from the force sensing device. The first low-pass filter has a first bandwidth and the second low-pass filter has a second bandwidth that is greater than the first bandwidth. The two low-pass filters filter the force signal to provide a user interface with a precise feel for slower more deliberate input while also providing fast response times for stronger, shorter input.

1. A method for determining a type of input received on a surface of an electronic device, the method comprising:
receiving a continuous force signal from a force sensing device; providing the force signal to a first low-pass filter having a first bandwidth; concurrently providing the force signal to a second low-pass filter having a second bandwidth that is greater than the first bandwidth; determining, within a first time period, whether the force signal exceeds a first threshold associated with the first low-pass filter; and determining, within a second time period, whether the force signal exceeds a second threshold associated with the second low-pass filter, wherein the second time period is shorter than the first time period and the second threshold is higher than the first threshold.
