Problems solved by technology

Although some slideshow playback software can provide the speaker with functions such as laser pointer and paintbrush, it requires the speaker to sit in front of the computer screen and use the mouse to operate, which is cumbersome. During the screen process, the content of the speech cannot be marked
In addition, when multi-site multi-screen conference projection is performed, the remote projection screen cannot display the on-site logo made by the speaker locally, which affects work efficiency

Embodiment 1

[0041] Figure 1a It is a flow chart of an annotation display method applied to a screen projection device provided by Embodiment 1 of the present invention. This embodiment can be applied to any situation that requires annotation of screen projection content. The method can be executed by an annotation display device, which It can be realized by means of software and / or hardware, and can be integrated on the screen projection device.

[0042] In the embodiment of the present invention, firstly, the screen projection device is respectively connected to the computer terminal and the projection screen, and the target file on the computer terminal is projected and displayed on the projection screen. Further, in order to realize the identification of the screen projection content through the mobile terminal, it is necessary to establish a connection between the screen projection device and the mobile terminal. Exemplarily, the screen projection device can establish a connection wi...

Embodiment 2

[0053] Figure 2a It is a flow chart of the annotation display method applied to the screen projection device provided by the second embodiment of the present invention. The second embodiment is further optimized on the basis of the first embodiment. Such as Figure 2a As shown, the method includes:

[0054] S201. In response to a paintbrush request from a mobile terminal, determine the current position of the laser pointer, and create a paintbrush canvas on the canvas currently displayed on the screen.

[0055] In the embodiment of the present invention, the brush request may be triggered by performing a second preset operation on the laser pointer button, wherein the second preset operation at least includes: pressing and holding the laser pointer button, and moving to the mobile terminal The brush launch area on the interface. Exemplary, such as Figure 2b As shown, it shows a schematic diagram of the interface of the mobile terminal including the laser pointer button 1...

Abstract

The embodiment of the invention discloses a label display method and device, screen projection equipment, a terminal and a storage medium, and the method applied to the screen projection equipment comprises the steps: responding to a laser pointer request from a mobile terminal, and displaying a laser pointer at a preset initial position of a screen projection screen; acquiring pose information ofthe mobile terminal in real time, and determining a target position of the laser pointer on the projection screen according to a position conversion relation between the pose information and the projection screen; and moving the laser pointer from the initial position to the target position on the projection screen. According to the embodiment of the invention, the mobile terminal is connected with the screen projection equipment, and the mobile terminal is used as a remote controller for labeling in the screen projection process, so that the operation is simple and convenient, the cost is low, and labeling contents can be synchronously displayed during remote screen projection.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of the Internet, and in particular to a label display method and device, a screen projection device, a terminal and a storage medium. Background technique [0002] With the rapid development of the Internet of Things technology, the integration between devices is getting closer and closer. Traditional projection screens need to be connected through VGA, DVI or HDMI cables, and connected to a computer through a laser pointer to turn pages and demonstrate key points. Now, you can also directly wirelessly cast the screen of your computer or mobile phone to the big screen through the projection box, which saves the trouble of carrying adapters and other accessories. [0003] However, during the conference projection process, the speaker needs to indicate the key points, on-site signs, and paint some important content for the audience according to the content of the speech. Although som...
