Abstract
A slide type mobile terminal and a method for preventing unintended operation of the same are disclosed. When an event is generated, indicating movement of the assemblies of the mobile terminal with respect to each other, a determination is made whether the movement is detected within a preset time after generation of at least one of a touch down event and a touch up event, and ignores those events determined to be within the preset time by not delivering the touch events to a related application program.
Claims16
A method for operating a mobile terminal, comprising:
- detecting touch on a touch screen by a touch sensor;
- generating a touch event in response to detecting the touch, the touch event comprising at least one of a touch down event and a touch up event;
- storing the touch event in a buffer;
- determining whether the touch is one of accidental or intentional by detecting whether a sliding event corresponding a sliding motion occurs within a present time in which the touch event is generated;
- ignoring the touch event by discarding the touch event stored in the buffer when the touch event is determined to be accidental when a sliding event corresponding to sliding motion occurs within a preset time duration;
- and
- processing the touch event as intentional when the sliding event corresponding to sliding motion does not occur within the preset time duration,
- setting a delay zone on the touch screen, wherein setting a delay zone on the touch screen at which a buffering time for the touch event generated at the delay zone is longer than a buffering time for the touch event generated at a non-delay zone, and
- wherein a left-zone or a right zone is set as the delay zone according by a user changeable default.

A mobile terminal comprising:
- a first assembly having a touch screen having a display unit and a touch sensor that senses touch on the touch screen;
- a second assembly coupled to the first assembly and supporting a movement of the first assembly,
- a slide sensor for sensing sliding motion between the first assembly and the second assembly;
- a buffer for storing a touch event, the touch event comprising at least one of a touch down event and a touch up event;
- and
- a control unit for determining whether the touch event is accidental or intentional based on sensing whether sliding motion occurs within a preset time duration of the touch event, the control unit ignoring the touch event by discarding the touch event stored in the buffer, when the sliding motion is sensed as having occurred within the preset time duration, and
- wherein the touch screen includes a delay zone at which a buffering time for the touch event generated at the delay zone is longer than a buffering time for the touch event generated at a non-delay zone, and wherein the buffer data is discarded when the touch event is accidental, and
- wherein a left-zone or a right zone is set as the delay zone according by a user changeable default.
