Abstract

The present invention relates to an electronic abacus, which mainly includes a main body, a circuit board in connection with a computer, a display device and a keypad. The circuit board is disposed inside a frame. The display device and the keypad are disposed on the frame. A plurality of luminescent beads representative of a plurality of numerical value are dispose on the frame. As the circuit board is mainly composed of a microprocessor and a plurality of position sensors and the position sensors are disposed on the frame to correspond to the respective bead position, the position to which the bead is moved can be sensed and provided to the microprocessor. The microprocessor carries out the operation of the numerical values corresponding to the beads, and outputs a bead movement procedure and the final numerical value to the connected computer, allowing the computer to determine if user's finger operation is correct. Furthermore, a correct bead movement sequence can be expressed by controlling an illumination of beads. Doing so allows student to conduct a computer interactive teaching practice of abacus.
