Abstract

Disclosed is an interactive spatial orientation method and system. The method includes: sequentially scanning, by a scanning apparatus, a receiving apparatus in a first direction and a second direction perpendicular to each other; converting, by the receiving apparatus, received optical signals generated from the first scanning and the second scanning into radio waves carrying results of the first scanning and the second scanning, and transferring the radio waves to a processing apparatus; synthesizing, by the processing apparatus, the results of the first scanning and the second scanning to obtain six degrees of freedom information of the receiving apparatus. The system includes a scanning apparatus; a receiving apparatus; and a processing apparatus.
