USER INTERACTIVE DEVICE WITH A TOUCH PAD, A METHOD FOR ACQUIRING CONTROL DATA TO CONTROL THE USER INTERACTIVE DEVICE AND A METHOD FOR PERFORMING USER AUTHENTICATION IN THE USER INTERACTIVE DEVICE, CAPABLE OF IMPROVING A USE RATE OF A USER INTERFACE

摘要

PURPOSE: A user interactive device with a touch pad, a method for acquiring control data to control the user interactive device and a method for performing user authentication in the user interactive device are provided to efficiently control the user interactive device using direction data of data inputted through a touch pad or the direction data and time data.;CONSTITUTION: When a user touches a touch pad, a touch pad input processing unit(12) obtains location data of a contact start point and a contact end point. The touch pad input processing unit produces direction data from the location data of the contact start point and the contact end point. The touch pad input processing unit produces direction data using a directional vector between the contact start point and the contact end point. A controller(13) determines control data for controlling the user interactive data based on the direction data and the location data.;COPYRIGHT KIPO 2010
