Description

  The present invention relates to an optical pointing positioning device, and more particularly to an optical pointing positioning device that is excellent in operability and easy to use.

  Overall, optical mouse technology is already mature, and now it has evolved from an early wired optical mouse to a wireless optical mouse. The optical mouse mainly controls the movement of the cursor on the computer screen and related movements. The optical mouse projects a light beam onto a rough, flat surface, and then moves the reflected light beam inside. The general principle of operation is that the sensor receives and determines the movement direction and distance of the optical mouse.

  However, conventional optical mice have several drawbacks. First, the conventional optical mouse cannot sense unless it moves on a rough flat surface, in other words, it cannot sense even if it moves on a smooth flat surface. It is. Next, due to its shape limitation, when a conventional optical mouse is used for a long time, the wrist is burdened and easily inflamed.

In order to overcome the above-described problem, the optical mouse 1 disclosed in Patent Document 1 as shown in FIGS. 1 and 2 is configured to use a movable sensor of a conventional optical mouse from the opposite side. . In other words, the user's thumb is configured to be used as a substitute for a rough flat surface, and according to this, the user moves the thumb on the translucent plate 10 to move it on the computer screen. The movement of the cursor can be controlled. However, each time the cursor is moved and positioned, the optical mouse 1 moves the thumb out of the translucent plate 10 and then performs the selection and other functions on the buttons 21 and 21 of the optical mouse 1. However, there is a problem that the movement of the thumb may move the cursor again and shift the positioned cursor at this time.
