Abstract

The invention relates to an abacus type numerical input method and device. The numerical input device includes: a switch array, a matrix signal scanning module, a matrix signal conversion module, and a numerical synthesis module. The numerical value input method comprises the following steps: 1) detecting the current positions of the beads on the abacus in each row on the abacus; 2) obtaining the decimal unit represented by the current positions of the beads in each row on the abacus according to the corresponding table Numerical value; 3) Synthesize the decimal unit value represented by the current position of each row of beads on the abacus into a decimal value; 4) Send the decimal value to the electronic data processing platform. The invention allows users to input decimal values ​​to the electronic data processing platform through the abacus, which is especially suitable for skilled abacus users to input values ​​to the electronic data processing platform through their abacus, so it can provide a more rapid And efficient numerical input tool.

Description

1. Technical field [0001] The invention relates to an abacus type numerical input method and device. 2. Background technology [0002] The abacus is a traditional Chinese counting and calculation tool, which has the characteristics of intuitive calculation and quick operation. Because of this, even in today's increasingly computerized world, the abacus is still an indispensable computing tool in many fields. In the vast colleges and universities with accounting majors and even other financial majors, abacus is still a compulsory course that must reach a certain level before graduation. [0003] In the use of personal computers, users can currently input text and values ​​into personal computers through various peripheral input devices, such as keyboards, pointer devices (mouse, touch pads, trackballs), handwriting panels, etc. In the computer, the high-speed computing power of the personal computer is used to process such data. The keyboard is a comprehensive input device...
