1. Technical Field
The present disclosure relates to a cursor control device and an apparatus having such cursor control device.
2. Description of Related Art
Currently, besides touch control, a mouse is usually used for controlling a cursor on a device. However, the mouse is not easy to carry with ease, and when in use, the mouse has to be moved on a pad or a flat desk surface. The touch control needs the finger moves to different positions of a touch panel. With the ongoing development of large display, touch control becomes harder and harder.
What is needed, therefore, is a cursor control device and an apparatus having same, which can overcome the above shortcomings.
Many aspects of the present cursor control device and apparatus can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present cursor control device and apparatus. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
Embodiments of the present cursor control device and apparatus will now be described in detail below and with reference to the drawings.

The main body 10 can be located on a bracket 11 which can be located on a desk or on other objects. The detection module 20 is located in a top end of the main body 10. The detection module 20 has an image capturing unit (camera module) defining a detectable region on the desk. If user's fingers or other objects move in the detectable region, the detection module 20 is capable of capturing successive images of the fingers or other objects, then converting the successive images into movement track signals of the fingers and other objects in the detectable region.
The information identifying module 30 is electrically connected to the detection module 20 to receive signals from the detection module 20 and feedback thereto. The information identifying module 30 includes an information storage unit 31 and an information comparing unit 32. The information storage unit 31 stores predetermined images of fingers and other predetermined objects. The comparing element 32 is used to compare in-time captured images from the detection module 20 with the predetermined images stored in the information storage unit 31. If a compared result shows an in-time captured image is inconsistent with one of the predetermined images, the information identifying module 30 feedbacks nothing to the detection module 20.
If a compared result shows an in-time captured image is consistent with one of the predetermined images, the information identifying module 30 feedbacks a tracking order to the detection module 20, then the detection module 20 captures successive images of the identified object, and converts the successive images into movement track signals.
In application, the information storage unit 31 can store images of finger ends of one or more predetermined users, such as figure images of the finger ends. When one of such fingers appears on the detectable region, the detection module 20 can capture an image of the finger and the information comparing unit 32 can receive an image signal from the detection module 20 and compare the image signal with the predetermined images stored in the information storage unit 31. After receiving a tracking order from the information identifying module 30, the detection module 20 begins to capture successive images of the finger according to movements of the finger, and convert the successive images into movement track signals of the finger. The movements of the finger include movements in a three-dimensional space within the detectable region, that is, the detection module 20 is configured for determining the three-dimensional movement track of the object in the detectable region.
The signal processing unit 40 is electrically connected to the detection module 20 and configured to covert the movement track signals into cursor control signals. The signal processing unit 40 can also read a user's click and double-click in the detectable region to be those similar to the user's click and double-click on the left mouse button and right mouse right button based on movements of the user's fingers along a Z-axis.
The cursor control device 100 can be disposed in front of users, and a host which to be controlled can be located in front of the cursor control device 100, not necessarily facing thereto as long as the users can read display of the host. The cursor control device 100 has a wire transmission system and a wireless transmission system mounted therein, such that the signal processing unit 40 can be connected to the host via wires, wireless Bluetooth or wireless infrared transmission system.
The information identifying module 30 further includes a user's ID and password identifying unit. The main body 10 includes a keyboard, a display screen mounted thereon to support the user's ID and password identifying unit. If an input ID or password is correct, the information identifying module 30 can also give the tracking order to the detection module 20. In particular, each ID corresponds to a cursor defined in the cursor control device 100, and the cursors in the cursor control device 100 can have different designs which then shown on a display.
It is understood that the main body 10 can be a mobile phone. The information identifying module 30 can be called an object segmentation module. The wire transmission system and wireless transmission system are configured to be a signal sending module.
