Tracking system for tracking and rendering virtual object corresponding to physical object and the operating method for the same

A computer-implement operating method, adapted to a tracking system, wherein the tracking system comprises a wearable electronic device and at least one tag device disposed in a physical object, the method comprising:

• transmitting, by an anchor array of the wearable electronic device, a plurality of request wireless signals, wherein each of the request wireless signals includes a transmitting time of that said each of the request wireless signals;
• in response to receiving the request wireless signals by the at least one tag device, transmitting a plurality corresponding response wireless signals by the at least one tag device;
• in response to receiving the corresponding response wireless signals by the anchor array, calculating a plurality of distances between the at least one 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 by a processor of the wearable electronic device;
• calculating, by the processor, a relative coordinate of the at least one tag device according to the distances;
• calculating, by the processor, an absolute coordinate of the at least one tag device according to the relative coordinate and a reference coordinate of a reference point of the wearable electronic device, wherein the reference coordinate is an absolute coordinate of the reference point in a virtual space corresponding to the wearable electronic device;
• and
• in response to the absolute coordinate of the at least one tag device is identified as being in a seen space of the virtual space by the processor, rendering at least on part of a virtual object corresponding to the physical object into the seen space according to the absolute coordinate of the at least one tag device by a display device of the wearable electronic device, wherein the at least one part of the virtual object is corresponding to at least one part of the physical object, and the at least one tag device is disposed in the at least one part of the physical object.

A tracking system, comprising:

• a wearable electronic device, wherein the wearable electronic device comprises an anchor array, a processor and a display device;
• and
• at least one tag device, wherein the at least one tag device is disposed in a physical object,
• wherein the at least one tag device is configured to broadcast a wireless signal, wherein the wireless signal includes a transmitting time of the wireless signal,
• wherein in response to receiving the wireless signal by the anchor array, the processor is configured to calculate a plurality of distances between the at least one tag device and a plurality of anchor devices of the anchor array according to the wireless signal,
• wherein the processor is configured to calculate a relative coordinate of the at least one tag device according to the distances,
• wherein the processor is configured to calculate an absolute coordinate of the at least one tag device according to the relative coordinate of the at least one tag device and a reference coordinate of a reference point of the wearable electronic device,
• wherein in response to the absolute coordinate of the at least one tag device is identified as being in a seen space of a virtual space by the processor, the processor is configured to instruct the display device to render at least one part of a virtual object corresponding to the physical object into the seen space according to the absolute coordinate of the at least one tag device, wherein the at least one part of the virtual object is corresponding to at least one part of the physical object, and the at least one tag device is disposed in the at least one part of the physical object.
