Method and apparatus for providing user interface based on contact position and intensity of contact force on touch screen
First Claim
1. A method of providing a user interface using a touch input unit comprising a touch screen configured to detect a contact position and a contact force, the method comprising:
- receiving, at the touch input unit, a touch input signal generated by a touch of a user'"'"'s pointing object;
executing a step of a position processing unit identifying a contact position, corresponding to the received touch input signal, and a step of an intensity processing unit analyzing an intensity pattern of contact force, corresponding to the received touch input signal, simultaneously or sequentially;
determining, at a control unit, an event corresponding to the touch input signal based on the identified contact position and the analyzed intensity pattern of contact force; and
outputting, at an output unit, the determined event to a display screen.
