1. An electronic device comprising:
- a display;
a touch panel with a number of electrodes, placed on the display;
a processor electrically connected to the display and the touch panel; and
a memory electrically connected to the processor,wherein the memory stores instructions which enable the processor to;
receive a user input applied to at least part of the touch panel,add changes in capacitance formed among at least part of the electrodes, in response to the user input, anddetermine a level of pressure of the user input against the touch panel, based on a sum of capacitance changes.

Abstract
A method of providing pressure and an electronic device adapted thereto is provided. The electronic device includes a display, a touch panel with a number of electrodes, placed on the display, a processor electrically connected to the display and the touch panel, and a memory electrically connected to the processor. The memory stores instructions which enable the processor to receive a user input applied to at least part of the touch panel, add changes in capacitance formed among at least part of the electrodes, in response to the user input, and determine a level of pressure of the user input against the touch panel, based on a sum of capacitance changes. Various embodiments are provided.

17. An electronic device comprising:
-
a display; a touch panel placed on the display; a processor electrically connected to the display and the touch panel; and a memory electrically connected to the processor, wherein the memory stores instructions which enable the processor to; receive a first user input touching a contact region of a selected area on the touch panel, with a first level of pressure, for a selected period of time from a time point that the first user input is applied, execute a first function in response to the first user input, receive a second user input touching another contact region of the same selected area on the touch panel, with a second level of pressure, for the selected period of time from a time point that the second user input is applied, and execute a second function, which differs in type or in degree from the first unction, in response to the second user input. - View Dependent Claims (18, 19, 20)
