Embodiment 1

[0017] Embodiment 1: as figure 1 As shown, the method for realizing virtual mouse and touch operation by a laser pointer according to the present invention specifically includes a host computer 13, a laser pointer 11 and a projector 10; wherein the operating system of the host computer 13 is an Android system or Microsoft Windows (series ), the host 13 outputs the video to the projector 10, and the image is projected onto the curtain 12. The user turns on the toggle switch on the laser pointer 11, and the laser pointer 11 starts to emit laser light. Laser pen left key or right key, laser pen 11 transmits wireless signal through wireless transmitting device 110 to notify host 13 of the button event, camera 14 on host 13 takes images, and the image processing software installed in the host system calculates The coordinates of the laser spot are equivalent to the coordinates of the mouse in the operating system. The virtual human-computer interaction software embedded in the host...

Embodiment 2

[0018] Embodiment 2: as figure 2 As shown, Embodiment 2 of the present invention includes a laser pointer 11 and a smart projector 10, and this smart projector includes a host 13 described in Embodiment 1, and a camera 102 (such as image 3 as shown); combining the projector and the host into one is a combination of the two.

[0019] Preferably, the wireless signal transmission between the laser pointer 11 and the host 13 is realized through the USB wireless receiver 101, and the USB receiver 101 is plugged into the USB interface of the host during operation.

[0020] When used specifically, such as Figure 4 As shown, the process flow of the method for realizing the virtual mouse and touch operation through the laser pen described in the present invention is (wherein the system of Embodiment 2 is taken as an example):

[0021] Step 1: Power on the smart projector, turn it on, and project images to the screen;

[0022] Step 2: Turn on the toggle switch of the laser pointer...

Abstract

The invention provides a method for realizing a virtual mouse and touch operation through a laser pen. The method is performed by a laser pen, a host machine and a projector, wherein the host machine is provided with an Android system or a Windows system, image processing software which is used for calculating the light-spot coordinate of the laser pen and virtual man-machine interaction device software which is used for realizing virtual mouse key events are mounted in the system; the host machine is provided with a camera and a wireless receiving device; the host machine is fixed on the projector, and the pointing direction of the camera on the host machine is the same as the projecting direction of the projector; a wireless transmitting circuit is arranged in the laser pen, and a toggle switch and a key are at least arranged on the laser pen; when the toggle switch is turned on, the laser can be transmitted by the laser pen; the key is pressed and released, and the key events can be used for transmitting wireless signals to the wireless receiving device through the wireless transmitting circuit to notice the host machine to carry out the corresponding key operation. The method disclosed by the invention has the advantages that the framework realization is simple, the usage habits of the users are satisfied and the like.

Description

technical field [0001] The invention relates to a method for realizing virtual mouse and touch operation through a laser pointer, and its application range is large-screen interactive systems, especially projection applications; in particular, it relates to a laser pointer, image recognition, and human-computer interaction equipment. Background technique [0002] Projectors or large-screen displays are widely used in multimedia teaching, conferences, speeches and other activities. During a general presentation, there is an interactive function between the presenter and the presentation content. At present, in most cases, the computer outputs the presentation content to the projector or monitor, and the speaker generally has two ways to control the computer: 1) By mouse or keyboard control, which is very inconvenient for standing presenters; 2) Controlled by a remote page turner, this method is only suitable for operating documents to turn pages, and the control has limitati...
