摘要 |
An eraser comprises an erasing surface for erasing information from a writing board and a device (42) for creating an electronic representation of the erased information. The device (42) for creating an electronic representation comprises a light sensitive detector (14) which is adapted to detect a position-coding pattern on the writing board for a current eraser position, and a processor (16), which is adapted to interpret the position-coding pattern detected by the detector (14) and transform it into a coordinate pair of the current position. The processor (16) is further adapted to determine an angular position of the position-coding pattern on the detector (14). The processor (16) is adapted to determine the erased area on the writing board based on the determined angular position and knowledge of the size of the erasing surface of the eraser. |
