A panel device is installed in a machine for setting a numerical data in a desired updating mode to input the same into the machine. The panel device has a display panel for displaying a plurality of numerical data. A pointing tool is manually handled to touch the display panel for designating a requested one of the numerical data to be set, and is moved for drawing a gesture pattern. A fiat sensor is coupled to the pointing tool for detecting the drawn gesture pattern. An analyzer analyzes the detected gesture pattern to determine a particular updating mode associated to the gesture pattern. A processor carries out setting of the designated numerical data according to the determined updating mode.
