<p><P>PROBLEM TO BE SOLVED: To provide a user interface device that prevents false touch, even in a vibrating environment. <P>SOLUTION: In the user interface device, a touch panel 12 outputs a central position (ox, oy) in a display unit 11 and a three-dimensional relative position (x, y, z) relative to Z=0 to a display control unit 14. An acceleration sensor 13 outputs an acceleration of the user interface device to the display control unit 14. The display control unit 14 calculates x-LPF coefficient px, y-LPF coefficient py and z-LPF coefficient pz from the acceleration. The display control unit 14 calculates a new center position ox through low-pass filter operation using px to the X-coordinate x, and calculates a new center position oy through low-pass filter operation using py to the Y-coordinate y. The display control unit 14 also calculates an enlargement factor r through low-pass filter operation using pz to the Z-coordinate z. A display unit 11 displays display information based on the center position (ox, oy) and the enlargement factor r. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
