Pointing stick, method and device for pointing stick information conversion, and electronic equipment

Abstract

The invention provides a pointing stick, a method and device for pointing stick information conversion, and electronic equipment. The device for the pointing stick information conversion comprises an acquiring module for acquiring image information formed as a touch end face of the pointing stick is touched, a detection module for identifying and detecting the acquired image information, and a conversion module for converting a detected result into mouse input information comprising mouse coordinate information and mouse moving speed information, and further the electric equipment such as a control module in a laptop can control a mouse to move according to the mouse coordinate information and the mouse moving speed information. The device for the pointing stick information conversion disclosed by the invention avoids the accumulation of external force errors by the mouse input information acquired through utilizing an image processing technology, so the control accuracy of the mouse is improved.

Description

technical field [0001] The present application relates to the technical field of notebooks, in particular to a pointing stick, a pointing stick information conversion method, device and electronic equipment. Background technique [0002] The pointing stick is a device installed in the notebook to control the movement of the mouse. At present, the commonly used pointing sticks in notebooks include: metal rods, rod caps arranged on the metal rods, ceramic sheets and mouse buttons arranged under the metal rods, such as the pointing sticks in thinkpad notebooks, wherein the metal rods are arranged on the G of the keyboard. , H and B between the three keys, the mouse button is located below the space bar. [0003] The working principle of the above-mentioned pointing stick is that under the pressure of the user pressing the rod cap, the metal rod squeezes the ceramic sheet below it, and the ceramic sheet is deformed, thereby changing the resistance of the ceramic sheet, and then...

AI Technical Summary

Problems solved by technology

[0004] However, the existing pointing stick needs to go through the mechanical control method of the rod cap, the metal rod and the ceramic sheet in sequence, so that the resistance of the ceramic sheet changes, and then generates an electrical signal as the input information of the mouse.

However, the external force error accumulates with the increase of the number of transmissions during the mechanical transmission process, thereby reducing the accuracy of mouse control
