Abstract:
1. A method of determining a coordinate on a micro dotmap according to a moving vector, comprising: decoding a first coordinate of a first frame corresponding to a first displaying medium according to the first frame retrieved by scanning the first displaying medium at a first moment, the first displaying medium including a micro dotmap displayed thereon, and the first coordinate indicates a coordinate of a first encoding block on the displayed micro dotmap; scanning the first displaying medium at a second moment to retrieve a second frame, wherein the second moment is later than the first moment; calculating a first moving vector according to at least one difference between the first frame and the second frame; and determining a second coordinate of the second frame corresponding to the first displaying medium according to both the first coordinate and the first moving vector; wherein the first displaying medium is an electronic displaying device, the micro dotmap is printed on a transparent plate with paints or inks, and the transparent plate is disposed above a displaying panel comprised by the electronic displaying device.
