Problems solved by technology

However, this kind of optical mouse uses the change of the captured image to detect the displacement of the mouse. If it is used on a smooth and texture-free desktop, the image captured by the image sensor There will be no changes due to mouse movement, which will invalidate the function of the mouse on this type of desktop, resulting in restrictions on use
Furthermore, when the user does not have enough space to use and move the optical mouse, it will cause inconvenience and restrictions for the user in use.
Therefore, the known optical mouse still has many shortcomings to be improved urgently

[0035] figure 1 and figure 2 They are a top view and a cross-sectional view of the cursor control device according to the first embodiment of the present invention, respectively. Please also refer to figure 1 and figure 2 , the same label in the figure represents the same object. The cursor control device 100 of this embodiment is used to control the cursor on the display screen, which mainly includes an optical mouse 110 , a pad 120 and a protective device 130 , and the optical mouse 110 is provided with a light sensor 140 and a plurality of pressure sensors 150 . The detailed functions of each object are described below:

[0036] like figure 2 As shown, the optical mouse 110 of this embodiment includes an upper disc 160 and a lower disc 170 , and the two are connected by a support 180 . In addition, the optical sensor 140 is arranged in the pillar 180 , and a plurality of pressure sensors 150 are arranged around the pillar 180 . Wherein, the light sensor 140 is ju...

[0052] Based on the cursor control devices described in the first and second embodiments above, a special cursor control method can be derived, that is, combining the characteristics of the optical sensor and the pressure sensor, and matching the moving position of the optical mouse, the displacement direction and Displacement and other movement information, and then achieve the purpose of controlling the cursor movement.

[0053] Image 6 It is a flowchart of a cursor control method drawn according to the third embodiment of the present invention. Please refer to Image 6 , the present embodiment is to control the cursor on the display screen by detecting the displacement information of the optical mouse moving on a pad, and the displacement information generated according to the position of the contacted pressure sensor. The steps are described in detail as follows:

[0054]First, a frame reflected on the pad is captured by the optical sensor on the optical mouse as a refe...

Abstract

A kind of cursor control device and method, the invention adopts structure of combining optics mouse and protecting cushion, and combining displacement information detected by optical sensor and pressure sensor, so precise measurement in limited space can be realized to control movement of cursor on display screen. Besides, power needed by the optics mouse can be provided via protecting cushion, so load of using optics mouse can be lightened.

Description

technical field [0001] The present invention relates to a cursor control device and method, and a portable electronic device having the cursor control device, and more particularly, to an optical mouse suitable for operating on any surface and a cursor control method thereof, as well as the optical mouse and the cursor control method thereof. Portable electronic device with mouse. Background technique [0002] With the increasing popularity of personal computers, various computer peripheral products have also been introduced to meet the different needs of consumers, among which the most widely used is the mouse that can control the movement of the cursor on the display screen. Traditional mice, depending on the way they detect movement, can be divided into two categories: non-optical mechanisms and optical mechanisms. The common non-optical mechanism is to use the spherical scroll wheel in the bottom of the mouse to detect movement, such as US Pat. [0003] US Patent No. 5...
