Title:
CONDUCTIVE PATTERN READING DEVICE AND METHOD, AND INTERACTIVE PLATFORM USING SAME
Document Type and Number:
WIPO Patent Application WO/2017/084140
Kind Code:
A1
Abstract:
A conductive pattern (401) reading device and method, and an interactive platform. The reading device comprises a sensing circuit board (300) and a medium (400) printed with conductive patterns (401). The medium (400) is provided with one or more conductive sensing regions (402), wherein the conductive patterns (401) are printed in corresponding conductive sensing regions (402). The sensing circuit board (300) comprises one or more conductive sensing blocks (301) corresponding to the conductive sensing regions (402), and further comprises a sensing chip (100) used for sensing and measuring capacitance values of the various conductive sensing blocks (301). The sensing chip (100) is connected to the various conductive sensing blocks (301). Printing the conductive patterns (401) on the medium (400) rather than providing a chip and/or a coil in the medium (400) can reduce the production costs of the medium (400). Operations can be easily implemented by using simple stickers or cards, and the stickers or cards can be provided at different positions, thereby achieving flexible use.
