Abstract
An example display apparatus includes a first signal transceiver; a second signal transceiver installed at a position different from the first signal transceiver; a processor configured to determine a position in a two-dimensional space or a three-dimensional space of at least one detection object using the first signal transceiver and the second signal transceiver, and to generate a control signal corresponding to the position of the at least one detection object; and a display configured to operate according to the control signal.
Claims13
A display apparatus comprising:
- a first signal transceiver;
- a second signal transceiver installed at a position different from the first signal transceiver;
- a display;
- and
- a processor configured to:
- control at least one of the first signal transceiver or the second signal transceiver to radiate a first electromagnetic wave of a first frequency;
- based on at least one of the first signal transceiver or the second signal transceiver receiving a first reflected wave reflected from at least one detection object, control the first signal transceiver to radiate a second electromagnetic wave of a second frequency higher than the first frequency;
- and control the second signal transceiver to radiate a third electromagnetic wave of a third frequency higher than the first frequency;
- determine a position of the at least one detection object based on a second reflected wave corresponding to the second electromagnetic wave and a third reflected wave corresponding to the third electromagnetic wave;
- generate a control signal corresponding to the position of the at least one detection object;
- and
- control the display to operate based on the control signal,
- wherein the processor is further configured to control the first signal transceiver to transmit a fourth electromagnetic wave of a fourth frequency that is higher than the first frequency and lower than the second frequency and to control the second signal transceiver to transmit a fifth electromagnetic wave of a fifth frequency that is higher than the first frequency and lower than the third frequency,
- wherein the first signal transceiver is configured to receive a fourth reflected wave corresponding to the fourth electromagnetic wave, and
- wherein the second signal transceiver is configured to receive a fifth reflected wave corresponding to the fifth electromagnetic wave.
