Abstract
An augmented reality (AR) system time-reverses a detection signal and a data signal based on a location detection signal, and outputs the time-reversed detection signal and data signal. Accordingly, data transmission efficiency may increase.
Claims20
An augmented reality (AR) generating device comprising:
- a modulator configured to modulate a first phase of at least one data signal comprising information about an AR object;
- a phase detector configured to detect a second phase of at least one location notification signal received from an AR display device;
- a processor configured to control the modulator to time-reverse the first phase of the at least one data signal based on the second phase of the at least one location notification signal;
- and
- a plurality of antennas configured to receive the at least one location notification signal in a first frequency band from the AR display device and transmit the time-reversed at least one data signal to the AR display device in a second frequency band different from the first frequency band.
