Abstract: Multiple infrared-light LEDs are aligned in the left-right direction, below the display surface of a display, and the approach position Gx of an object approaching the display surface is calculated from the distribution of the respective intensities of infrared light beams emitted from the LEDs in a front, oblique direction. Based on the horizontal coordinate Tx of a touch position on the touch panel and the approach position Gx, a user in a driver's seat, positioned right of the display, is identified as the touching operator of the touch panel if the approach position Gx is located Th1 or more apart to the right from the coordinate Tx, and a user in a passenger's seat, positioned left of the display, is identified as the touching operator if the approach position Gx is located Th1 or more apart to the left from the coordinate Tx.

Abstract: An electrostatic-capacitive proximity detecting device includes an electrode unit including a plurality of electrodes linearly arranged along one direction; an electrostatic capacitance detector that drives the electrodes in a time division manner and detects detection values corresponding to electrostatic capacitances between a to-be-detected object and the respective electrodes; and a position detector that detects a position of the to-be-detected object in the one direction, based on arrangement positions of the respective electrodes in the one direction and a bias in magnitudes of the detection values detected for the respective electrodes by the electrostatic capacitance detector.
