DIGITAL EDUCATION CHARACTER RECOGNITION SYSTEM

摘要

A character recognition system for digital education is arranged to improve efficiency of education, and by prompt, children input a correct answer, form toy slip gauge using by 3D blocks. A character recognition system for digital education includes that a key matrix (202), a key-press input unit (210), a controller (220), an interface (230) and a LED (light emitting diode) show (240). Key matrix makes a lattice structure have multiple hall ICs, corresponds to the bottom magnet of function key or a toy slip gauge. Hall IC (integrated circuit) generates a switching signal, is confirmed by controller. Controller delivers switching signal from key matrix to a personal computer, when being received from the request of personal computer by interface. One stressed button reads again the value of the function key of toy slip gauge.
