US 8,139,048 B2 · Method of raising resolution in locating on a micro dotmap

Abstract

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.
