DISPLAY APPARATUS, POINTING APPARATUS, POINTING SYSTEM AND CONTROL METHODS THEREOF
First Claim
1. A display apparatus comprising:
- at least one speaker configured to output a sound signal;
a display configured to display a pointing object;
communication circuitry configured to communicate with a pointing apparatus to control a movement state of the pointing object, the pointing apparatus comprising a microphone to sense the sound signal; and
a processor configured to display the pointing object at a reference position determined based on an oriented direction of the pointing apparatus determined based on information of time including a time at which the pointing apparatus senses the sound signal after a trigger signal for setting the reference position of the pointing object on a screen of the display is received by the display apparatus from the pointing apparatus.

Abstract
A display apparatus is provided. The display apparatus includes at least one speaker configured to output a sound signal; a display configured to display a pointing object; communication circuitry configured to communicate with a pointing apparatus for controlling a movement state of the pointing object, the pointing apparatus comprising a microphone to sense the sound signal; and a processor configured to display the pointing object at a reference position determined based on an oriented direction of the pointing apparatus determined based on information of time at which the pointing apparatus senses the sound signal, after a trigger signal for setting the reference position of the pointing object on a screen of the display is received from the pointing apparatus.

10. A pointing apparatus comprising:
-
communication circuitry configured to communicate with a display apparatus displaying a pointing object on a screen, the display apparatus comprising at least one speaker to output a sound signal; a microphone configured to sense a sound signal from the display apparatus; and a processor configured to determine an oriented direction based on information of time at which the sound signal from the display apparatus is sensed, to determine a reference position of the pointing object based on the oriented direction, and to transmit a control signal allowing the pointing object to be displayed at the reference position. - View Dependent Claims (11, 12)

13. A method of controlling a display apparatus, comprising:
-
receiving a trigger signal from a pointing apparatus for setting a reference position on a screen, the pointing apparatus including a microphone for sensing a sound signal; outputting the sound signal through at least one speaker; receiving, from the pointing apparatus, information of time at which the sound signal is sensed by the pointing apparatus; determining an oriented direction of the pointing apparatus based on the information of time; determining the reference position based on the oriented direction of the pointing apparatus; and displaying a pointing object at the reference position. - View Dependent Claims (14, 15, 16, 17, 18)
