Embedded Force Measurement

An electronic device, comprising:

• a display;
• a force measurement layer overlapping the display, wherein a capacitance associated with the force measurement layer changes from a baseline capacitance to a modified capacitance in response to a touch input;
• and
• processing circuitry configured to:
• determine a difference between the baseline capacitance and the modified capacitance;
• in response to determining the difference between the baseline capacitance and the modified capacitance, use the difference between the baseline capacitance and the modified capacitance to determine a magnitude of force of the touch input;
• and
• provide a graphical output to the display that depends on the magnitude of force of the touch input.

An electronic device, comprising:

• a display;
• an array of rows and columns of conductive structures;
• processing circuitry configured to:
• measure a capacitance associated with the array, wherein the capacitance changes from a first capacitance to a second capacitance in response to a touch input on the display and wherein there is a difference between the first capacitance and the second capacitance;
• and
• determine a magnitude of force of the touch input using the difference between the first capacitance and the second capacitance.
