Abstract
A tracking system and a computer-implement operating method for the same are provided. The method includes transmitting a plurality of request wireless signals; in response to receiving the request wireless signals by the tag device, transmitting a plurality corresponding response wireless signals by the tag device; in response to receiving the corresponding response wireless signals by the anchor array, calculating a plurality of distances between the tag device and each of a plurality of anchor devices of the anchor array according to the request wireless signals and the response wireless signals, and accordingly calculating an absolute coordinate of the tag device; and in response to the absolute coordinate of the tag device is identified as being in a seen space of the virtual space by the processor, rendering a virtual object corresponding to the physical object into the seen space according to the absolute coordinate of the tag device.
