| 摘要 |
This invention is a battery powered educational game for young children which comprises game-board units made of a transparent material (12), carrying on one surface an image (11), and on the opposite surface a marked passive code consisting of a set of indentations adapted to convert uniform illumination into an illuminating optical code (13); further comprising a base decoding unit for identifying individual game-boards (14), adapted to receive a game-board which contains at least one light source for illuminating the rim of the game-board and, due to total internal reflection, pumping light into the bulk of the transparent board, so activating the code on the game-board that renders it luminous. It further comprises electro-optical decoding means, and electronic logic means for game-board identification. |
