Keyboard entry system capable of dynamically displaying finger positions on computer monitor

Abstract

A keyboard entry system capable of dynamically displaying finger positions on a computer monitor is composed of the computer monitor, a computer motherboard, a decoder and a signal entering circuit which are all connected in sequence. The keyboard entry system further comprises a finger position circuit connected with the signal input end of the decoder and used for determining the finger positions, the signal input end of the finger position circuit and the signal input end of the signal entering circuit are connectedly arranged on input keys of a keyboard, the finger position circuit is connected with the signal input end of the decoder, the signal output end of the signal entering circuit is connected with the other signal input end of the decoder. By the arrangement, a user can see finger position on the keyboard from a screen, so that time in searching for the keyboard can be reduced, and keyboard entering efficiency can be improved; the probability of input errors is reduced; the user does not have to look down at the keyboard and frequently switch between the computer monitor and the keyboard, fatigue of the head is reduced, and the eye fatigue caused by frequent switching and focusing between light and darkness is reduced.

Description

technical field [0001] The invention relates to a keyboard input system. In particular, it relates to a keyboard input system capable of dynamically displaying finger positions on a display. Background technique [0002] The structure and principle of the existing widely used technology for inputting information from a keyboard to a computer is that a key-in signal is generated after the button is pressed, transmitted to a decoder, and then transmitted to the computer motherboard through a USB or PS2 interface, and then processed by the computer. Finally, the input code is displayed at the cursor place on the computer screen. [0003] There is a problem in the existing keyboard input system: the keyboard cannot perceive the position of people's fingers on the keyboard. Therefore, when inputting information, except for a few cases where touch typing is possible, the operator needs to constantly look down at the keyboard to find the key, and then Look again at the display to...

Problems solved by technology

[0003] There is a problem in the existing keyboard input system: the keyboard cannot perceive the position of people's fingers on the keyboard. Therefore, when inputting information, except for a few cases where touch typing is possible, the operator needs to constantly look down at the keyboard to find the key, and then Look again at the display to select the typed symbol

The existing keyboard input system cannot ensure that the characters entered on the screen are all the characters you want to input even when you are looking at the keyboard input with your eyes

This is because: ① It is impossible to ensure that the button is actually pressed, ② Press multiple buttons, ③ The input software with association function may give a variety of word combinations, and the operator still needs to look at the screen to make a choice

Since the head is constantly switching between the keyboard and the screen, it is prone to errors, which greatly reduces the input efficiency

At the same time, the eyes switch and focus back and forth between the keyboard and the screen, which is bright and dark, and are prone to fatigue
