Embodiment Construction

[0024] The embodiment of the method for realizing wireless mouse function, such as figure 1 shown.

[0025] The video camera with monochrome filter is used as a projected large-screen image of the computer monitor, and the image is continuously sent to the computer with Windows 98 operating system or Windows 2000 operating system or Windows me operating system or WindowsXP operating system as the operating system In the computer language, such as C language, the control processing software compiled according to the following two processing methods is pre-installed in the computer, and each input image is sequentially processed for illumination distribution, and the laser light is searched and identified in the image. spot;

[0026] The first case: the computer cannot find the laser light spot, start timing, the computer continues to search and identify the laser light spot in each newly input image, if the laser spot cannot be found and the duration is longer than a long time...

Abstract

The invention discloses a method and equipment to achieve wireless mouse function. The method uses vidicon with monochromatic filter (2) as projective large screen (5) of computer display, images are inputted to the computer (3) constantly, and the computer searches and identifies laser spots which are projected on the large screen by laser ferule (1). If can not find laser spot, the computer responds normal instruction; if laser spot can be get, display mouse cursor at laser spot; if the laser ferule switches for several times, it will be identified as single or double beating action, then acts single or double beating left key of mouse. The vidicon with monochromatic filter (2) is wire connected to the computer (3) which controls projector (4), the laser ferule is not connected to any equipment, it produces laser spots to projective large screen(5). The invention has the excellences such as convenient usage, small size, no electromagnetic interference, low cost, and so on.

Description

technical field [0001] The invention relates to a method and a device for realizing the function of a wireless mouse when a computer uses a projector for large-screen projection display, in particular to a method and a device for realizing the function of a passive wireless mouse based on a laser pointer and a camera. Background technique [0002] With the rapid development of computer, Internet and multimedia technology, the cost of multimedia teaching system has been greatly reduced, and it has become a commonly used teaching facility in universities and even primary and secondary schools. The mouse is the most important computer input control device in multimedia teaching. It is an assistant used to control the movement of the cursor on the projected large screen and conduct man-machine dialogue during multimedia teaching or demonstration. The original intention of inventing the mouse is to make the operation of the computer easier. However, although the mouse has undergo...
