  • Publication number: 20140085199
    Abstract: A method comprising measuring a change of capacitance associated with a user input approaching a display of an electronic device, determining whether the user input is within a proximity range of the display of the electronic device based on the change of capacitance, displaying a Graphical User Interface (GUI) object at a location of the display of the electronic device according to whether the user input is within the proximity range of the display of the electronic device, determining whether the user input is within a touch range of the display of the electronic device based on the change of capacitance, and performing a function at the location according to whether the user input is within the touch range of the display of the electronic device.

  • Patent number: 8643623
    Abstract: A portable terminal including a touch screen and method for displaying a cursor thereof are provided. The method includes determining whether a capacitance is equal to or greater than a first critical value and is less than a second critical value, if the change of the capacitance is sensed in the touch screen, displaying a cursor in an area where the change of the capacitance is sensed, if the capacitance is equal to or greater than the first critical value and is less than the second critical value, and performing a function corresponding to the area where the cursor is displayed, if the capacitance sensed in the area where the cursor is displayed is equal to or greater than the second critical value.
