Patent ID: 11294454

Abstract:
A method of determining relative position of an extended reality mobile display device connected to receive display data from a host device involves determining (S31), by the extended reality mobile display device, a position and orientation of the extended reality mobile display device at a transmit time and transmitting (S32) a first signal to the host device at the transmit time. The extended reality mobile display device then receives (S35) at a receive time a second signal transmitted (S34) from the host device upon receipt (S33) of the first signal. The extended reality mobile display device determines (S36) a position and orientation of the extended reality mobile display device at the receive time and determines a difference (S37) in the position and orientation of the extended reality mobile display device between the transmit and receive times. The extended reality mobile display device then corrects display data received from the host device based on the determined difference in the position and orientation of the extended reality mobile display device, and displays the corrected display data.
