摘要： While a plurality of encoding blocks included in a micro dotmap are used for marking coordinates and locating a frame center on a displaying medium, a resolution of locating the frame center is raised by finding a microdot having a shortest distance from the frame center respectively in two microdot sets of a header region, or by determining a distance scale between an origin of the encoding block and each of two parallel projection points of both the microdot sets corresponding to the frame center. Both the microdot sets correspond to different dimensions in representing the coordinate of the frame center. The closest one-dimensional coordinates are then combined to form a two-dimensional coordinate of the frame center. Therefore, while applying the abovementioned method on a touch screen manipulated with touches of an optical pen, movements of the frame center on the screen can be manipulated skillfully by a user.

摘要： When a user holds an optical scanning device to scan a micro dotmap on a displaying medium, a coordinate of a frame center of a retrieved frame on the displaying medium is calculated according to a decoding method for the micro dotmap in advance. A moving vector corresponding to a difference between difference frames scanned by the optical scanning device at different moments is calculated so that an instant location of the frame center on the displaying medium can be calculated anytime. Therefore, a large number of calculations brought by frequent decoding may be saved since merely a few calculations are required in calculating the moving vector. By further decoding the coordinate of the frame center at moments spaced with constant or variable intervals, errors brought by vibrations of the displaying medium are instantly fixed. Accumulated errors are avoided in the calculated instant locations of the frame center anytime.

摘要： An optical touch device includes an indication plane, two image sensing units and a processing unit. The two image sensing units are disposed at two corners of the indication plane diagonal to each other, respectively, and the two corners define a diagonal line connected therebetween. The processing unit is electrically connected to the two image sensing units. When two touch points are performed on the indication plane, the processing unit determines whether the two touch points are located at opposite sides of the diagonal line, respectively, according to images sensed by the two image sensing units. Once the two touch points are located at opposite sides of the diagonal line, respectively, the processing unit calculates and outputs coordinates of the two touch points immediately according to the images sensed by the two image sensing units.
