INFORMATION REPRODUCTION/I/O METHOD USING DOT PATTERN, INFORMATION REPRODUCTION DEVICE, MOBILE INFORMATION I/O DEVICE, AND ELECTRONIC TOY USING DOT PATTERN

摘要

The present invention proposes a dot pattern on which code information and x and y coordinate information can be defined even if the dot pattern is extremely small, and proposes an information reproducing method and an information reproducing device based on the dot pattern. More specifically, a medium such as a printed material on which is formed a dot pattern portion by arranging in accordance with a given rule dots generated by a dot code generating algorithm in order to recognize various kinds of multimedia information is scanned as image data by scanning means. Then, the image data is converted into code data. Multimedia information corresponding to the code data is read out of storing means to be reproduced.

主权项

1. A trace device comprising:
a touch panel including a transparent film on which is formed a dot pattern formed by arranging in accordance with a given rule dots generated by a dot code generating algorithm for recognition of various kinds of multimedia information; and scanning means for scanning image data of the dot pattern of the touch panel, wherein the touch panel is arranged over a paper sheet, and the paper sheet is traced by the scanning means by successively recognizing image data of points.
