18. A method, comprising:
setting a display device to a first mode, the setting of the display device to the first mode including:
receiving, by the display device, a first light signal emitted by an optical emitter device;
stopping, by the display device, emission of a second light signal; and
determining, by the display device, first and second coordinates of a position of the optical emitter device along first and second axes, respectively, based on the first light signal received by the display device;
setting the display device to a second mode, the setting of the display device to the second mode including:
emitting, by the display device, the second light signal;
receiving, by the display device, a reflected light signal that is the second light signal reflected from the optical emitter device; and
determining, by the display device, a third coordinate of the position of the optical emitter device along a third axis based on the reflected light signal; and
displaying, by the display device, the position of the optical emitter device, the display being in a plane extending along the first and second axes.
