Abstract
A method includes detecting first and second touches on the touch-sensitive display and determining a location of each of the first and second touches, determining, by a plurality of force sensors, reaction forces, for the first and second touches, and determining a respective applied force for each of the first and second touches based on the reaction forces and the locations of the first and second touches.
Claims14
A method comprising:
- detecting first and second touches on the touch-sensitive display and determining a location of each of the first and second touches;
- determining, by a plurality of force sensors, reaction forces for the first and second touches;
- and
- determining a respective applied force for each of the first and second touches based on the reaction forces and the locations of the first and second touches.
An electronic device comprising:
- a touch-sensitive display;
- a plurality of force sensors, each configured to determine a reaction force for first and second touches on the touch-sensitive display;
- a processor operably coupled to the force sensors and the touch-sensitive display to determine a respective applied force for each of the first and second touches based on the reaction forces and locations of the first and second touches.
The electronic device according to claim 14, wherein the processor determines the respective applied force based on a best square fit utilizing the reaction forces and the locations of the first and second touches.
