1. A vehicle display apparatus comprising:

  • a display;

    a touch sensor provided on an upper surface or a lower surface of the display;

    a plurality of light emitting units provided at a periphery of the display and configured to sequentially emit light;

    a plurality of light receiving units provided at the periphery of the display and configured to sequentially receive light in correspondence with the plurality of light emitting units that sequentially emit light; and

    a processor configured to;

    calculate intensity levels of light signals received by the plurality of light receiving units; and

    calculate a position of an external object based on the intensity levels of light signals received by the plurality of light receiving units,wherein the processor is further configured to;

    calculate that a user'"'"'s hand corresponds to the external object and is positioned between a first distance value and a second distance value from the display, the second distance value being smaller than the first distance value;

    based on the calculation that the user'"'"'s hand corresponds to the external object and is positioned between the first distance value and the second distance value from the display, calculate a motion of the user'"'"'s hand based on the light emitting units and the light receiving units;

    calculate that the user'"'"'s hand is positioned between the second distance value and a third distance value from the display or is positioned within the third distance value from the display, the third distance value being smaller than the second distance value; and

    based on the calculation that the user'"'"'s hand is positioned between the second distance value and the third distance value from the display or is positioned within the third distance value from the display;

    calculate a capacitance change sensed by the touch sensor; and

    calculate position information of the user'"'"'s hand based on the calculated capacitance change sensed by the touch sensor.
