| 摘要 | An apparatus (fig. 3, 6, 10-13, 15, 17-18, 21, 24, 28-29) for determining and retrieving positional information including a surface having a plurality of first elements and a plurality of second elements, a first detection element connected to at least one of the plurality of first elements, and a second detection element connected to at least one of the plurality of second elements. The detection elements may include pulse detection elements or current sensing circuits. The plurality of first elements and the plurality of second elements may include conductive and non-conductive threads, and the conductive threads may include piezoelectric crystals embedded in plastic. | ||||||
