Attached finger pointing control element

Abstract

The invention relates to an attached finger pointing control element, which is used for controlling a pointing pointer of a computer host. The pointing control element controls the pointing pointer by the thumb of a single hand and any one finger of the same hand or the thumb and the palm of the same hand. The pointing control element comprises an active sensing element and at least one passive sensing element, wherein the active sensing element is attached on the thumb of one hand; the single passive sensing element or a plurality of passive sensing elements are attached on the palm or other finger(s); the active sensing element is in contact with the surface of the passive sensing element(s) and moves relative to the passive sensing element(s) so as to detect an electric change signal generated when the active sensing element is in contact with the passive sensing element(s) and moves relative to the passive sensing element(s); and the pointing pointer of the computer host is further controlled. Therefore the problem of wrist carpal tunnel syndrome can be effectively solved; the action of the frequent round trip of the hand between a keyboard and a mouse is omitted; and the operation is direct and simple, so that the computer use efficiency is improved.

Description

technical field [0001] The present invention relates to a pasting-type finger pointing control device, in particular to a pointing control device that utilizes mutual movement between fingers to provide computer-controlled pointer displacement and vector. Background technique [0002] At present, the most popular pointing device used in computers is the mouse. Its operating principle mainly uses the track sensor to detect its own displacement signal (displacement and vector), and then controls the displayed screen pointer to generate the corresponding displacement and displacement through the host computer. vector. The traditional mouse track sensor can be mainly divided into two types: mechanical type and optical type. The mechanical type uses a rolling ball to touch and roll on the table to detect the displacement signal, while the optical type mouse uses the optical sensor to sense the displacement based on the principle of light reflection. Signal. [0003] The above-m...

Problems solved by technology

[0011] The above-mentioned three patents mainly generate displacement signals on desktop movement, direct scroll wheel or mini touch screen, so not only the displacement distance provided each time is insufficient, but also prone to misoperation during typing ( Such as touching the scroll wheel on the finger or touching the screen by mistake), causing difficulties for users to edit
