Embodiment Construction

[0032] The present invention will now be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown.

[0033] first, figure 1 is a schematic block diagram illustrating an input device for recognizing mixed coordinates using an absolute coordinate recognition method and a relative coordinate recognition method according to an embodiment of the present invention. When connected to an information terminal such as a personal computer, the coordinate input device operates a cursor displayed on a monitor to input commands, and input handwritten characters or images, or the device operates independently of the information terminal to input, Store or output handwritten characters, traces or images. The coordinate input device is composed of a mixed coordinate sensing unit 11 and a coordinate calculation unit 12. The mixed coordinate sensing unit 11 is used to obtain relative coordinate information by sensing the relativ...

Abstract

The present invention relates a coordinate input device to input a variety of job commands, diagrams or characters, and to store or output the input data. More particularly, the present invention provides an input device for recognizing hybrid coordinates and a method of operating the device. The input device uses an absolute coordinate recognition method and a relative coordinate recognition method in a combined fashion as a coordinate recognition method for inputting the track of the characters or diagrams. By doing so, input coordinates are converted into absolute coordinates, and the tracks of handwritten characters and diagrams are stored as the converted absolute coordinates such that the tracks are displayed on a display of the input device or on a monitor of an information terminalconnected to the input device. Accordingly, problems of respective conventional input devices for recognizing coordinates can be solved, the structure of hardware can be simplified, and characters ordiagrams can be input with accurate recognition of coordinates.

Description

technical field [0001] The invention relates to a coordinate input device for inputting various work commands, graphics or characters, and storing or outputting the input data. More specifically, the present invention provides an input device for recognizing mixed coordinates and a method of operating the same. The input device uses a combination of an absolute coordinate recognition method and a relative coordinate recognition method as a coordinate recognition method for the trajectory of input characters or graphics. In this way, using the absolute coordinates obtained by the absolute coordinate recognition method, the relative coordinates obtained by the relative coordinate recognition method are converted into absolute coordinates; and the traces of handwritten characters and graphics are stored as the obtained absolute coordinates and the conversion After the absolute coordinates, the trajectory is displayed on the display of the input device or displayed on the monitor...
