CPC G06F 3/0414 (2013.01) [G06F 1/1616 (2013.01); G06F 1/1643 (2013.01); G06F 1/1681 (2013.01)] | 18 Claims |
1. A computing device, comprising:
an enclosure defining an exterior of the computing device;
a display assembly comprising a display, the display assembly positioned at least partially within the enclosure and defining a user input surface;
a sidewall extending about at least one side of the display;
a first force-sensing circuitry positioned within a first portion of the sidewall or between the display and the first portion of the sidewall; and
a second force-sensing circuitry positioned within a second portion of the sidewall or between the display and the second portion of the sidewall;
a processing unit communicatively coupled to the first force-sensing circuitry and the second force-sensing circuitry, wherein:
each of the first force-sensing circuitry and the second force-sensing circuitry is configured to receive a drive signal; and
in response to a force input at the user input surface at a position along the user input surface, the first force-sensing circuitry is configured to output a first signal and the second force-sensing circuitry is configured to output a second signal, each of the first signal and the second signal corresponding to a respective capacitance with respect to the enclosure;
the processing unit is configured to determine the position of the force input based on a change in relative capacitance between first and the second signals.
