A three-dimensional input device, controlling a display of an electronic apparatus, comprising:
- an infrared ray emitting/receiving unit, electrically connected to the display and comprising an infrared ray emitter and an infrared ray receiver;
- a cursor control unit, comprising a reflective material and a radio frequency emitter;
- and
- a radio frequency receiving unit, electrically connected to the display,
- wherein the reflective material reflects infrared ray signals emitted by the infrared ray emitter, the infrared ray signals are reflected to the infrared ray receiver, and the infrared ray receiver transmits the infrared ray signals to the electric apparatus;
- and
- the radio frequency emitter emits radio frequency signals to the radio frequency receiving unit, and the radio frequency signals are transmitted to the electronic apparatus by the radio frequency receiving unit.
