INPUT DEVICE BASED ON A PROXIMITY SENSOR AND OPERATION METHOD USING THE SAME

摘要

PURPOSE: An input unit and their operating method of the proximity sensor base are provided so that the direction key function and rotation key function are compartmentalized based on a plurality of sensing information. The application or the presently activated content is controlled. CONSTITUTION: A proximity sensor unit(120) comprises a plurality of proximity sensors. A controller(150) collects the sensing information from the proximity sensors, and an input signal according to one or more function among top and bottom and diagonal direction keying function and shuttle function is created according to the order of the collected sensing information. A storage(140) at least stores one among the application program and contents. The controller activates the proximity sensor part in the activation of application or the contents.
