Abstract:The key to entity interaction lies in accurate tracking and recognition of the location and identity ID of a physical entity, but existing methods suffer from problems such as high technical costs or demanding environmental factors. To this end, a pressure-sensitive turn-on circuit-based interaction mode is proposed and a pressure-sensitive turn-on circuit-based educational product called FaceON is developed, which adopts a three-layer laminated matrix circuit structure combined with a PCB control module to realize the recognition and reading record of point ID signals through the row and column scanning method. The solution is characterized by low cost and stable operation, supporting game functions such as splicing, point-and-click and drawing, and the learning paper can be flexibly replaced, which enhances the product’s sustainability and potential for educational applications. Two experimental studies on teacher usability and children’s interactive experience of the product have demonstrated its potential application prospects in the field of education and its ability to effectively enhance children’s learning interest and cognitive ability.
