Data processing system, method for determining coordinates, and computer readable storage medium

A method for determining coordinates, adapted to a data processing device, comprising:

• receiving a plurality of positioning data, wherein the plurality of positioning data correspond to device positions of a plurality of positioning devices in a real world, and the positioning devices comprise a first positioning device and a second positioning device, wherein the plurality of positioning data comprise a first positioning data corresponding to a first device position of the first positioning device in the real world and a second positioning data corresponding to a second device position of the second positioning device in the real world;
• in response to determining that the first positioning device is selected via a user interface as a reference point of a coordinate system of a virtual world, determining a coordinate of the second positioning device in the coordinate system of the virtual world based on a relative position between the device positions of the first positioning device and the second positioning device;
• in response to determining that the second positioning device is selected as the reference point of the coordinate system of the virtual world, determining a coordinate of the first positioning device in the coordinate system of the virtual world based on the relative position between the device positions of the first positioning device and the second positioning device;
• providing a user interface, wherein the user interface shows a re-center function;
• and
• in response to determining that the re-center function is triggered, providing a plurality of detected positioning devices in the user interface, wherein the detected positioning devices comprise the first positioning device and the second positioning device.

A non-transitory computer readable storage medium, the computer readable storage medium recording an executable computer program, the executable computer program being loaded by a data processing device to perform steps of:

• receiving a plurality of positioning data, wherein the plurality of positioning data correspond to device positions of a plurality of positioning devices in a real world, and the positioning devices comprise a first positioning device and a second positioning device, wherein the plurality of positioning data comprise a first positioning data corresponding to a first device position of the first positioning device in the real world and a second positioning data corresponding to a second device position of the second positioning device in the real world;
• in response to determining that the first positioning device is selected via a user interface as a reference point of a coordinate system of a virtual world, determining a coordinate of the second positioning device in the coordinate system of the virtual world based on a relative position between the device positions of the first positioning device and the second positioning device;
• in response to determining that the second positioning device is selected as the reference point of the coordinate system of the virtual world, determining a coordinate of the first positioning device in the coordinate system of the virtual world based on the relative position between the device positions of the first positioning device and the second positioning device;
• providing a user interface, wherein the user interface shows a re-center function;
• and
• in response to determining that the re-center function is triggered, providing a plurality of detected positioning devices in the user interface, wherein the detected positioning devices comprise the first positioning device and the second positioning device.
