INPUT METHOD AND APPARATUS FOR CAPACITIVE TOUCH SCREEN TERMINAL
First Claim
1. An input method in a capacitive touch screen terminal, the input method comprising:
- detecting by a controller whether a request of a corresponding function is made;
verifying by the controller whether or not the requested corresponding function is to be executed by a non-contact touch sensing method on a touch screen; and
configuring a display of a non-contact touch sensing region of the touch screen set for executing the corresponding function in which the corresponding function is to be executed by performing the non-contact touch sensing method by the controller sensing a specific pattern of a finger or pointer approaching a surface of the non-contact touch sensing region of the touch screen so as to trigger at least one threshold sensed by a sensor.

Abstract
An input method and apparatus for implementing a non-contact touch sensing method according to a corresponding function in a capacitive touch screen terminal. The sensed capacitance varies as a finger or special pointer approaches the surface of the touchscreen without making actual contact, and different thresholds of capacitance can be used to trigger different functions. The method preferably includes sensing a request of a corresponding function, verifying whether or not the requested corresponding function is performed by a non-contact touch sensing method, and implementing a non-contact touch sensing region set for the corresponding function when the corresponding function is performed by the non-contact touch sensing method.
