Embodiment 1

[0130] figure 1 It is a flowchart of a comment display method provided by Embodiment 1 of the present invention.

[0131] The comment display method provided in this embodiment can be executed by a comment display device, which can be realized by software and / or hardware. The comment display device can be composed of two or more physical entities, or can be a physical entity Entity composition. The annotation shows that the device can be a computer, a mobile phone, a tablet, a projector or an interactive smart tablet, etc. In the embodiment, an interactive smart tablet is used as an example of an annotation display device for description, wherein the interactive smart tablet may be an integrated device that controls the content displayed on the display panel and realizes human-computer interaction through touch technology, It integrates one or more functions such as a projector, an electronic whiteboard, a curtain, a sound system, a TV, and a video conferencing terminal.

Embodiment 2

[0171] Figure 4 It is a flowchart of a comment display method provided by Embodiment 2 of the present invention. This embodiment is embodied on the basis of the first embodiment above. refer to Figure 4 , the comment display method provided in this embodiment specifically includes:

[0172] S201. Receive a screen projection instruction.

[0173] S202. Display the content of the first projected screen.

[0174] S203. Receive an annotation trigger instruction.

[0175]Specifically, the annotation trigger instruction is used to start the annotation function. Among them, the user can send a comment trigger instruction to the interactive smart tablet by clicking a set button or inputting a set touch operation (such as double-click, long press, multi-touch or circle selection). For example, the interactive smart tablet adds a virtual button on the display screen, and when the interactive smart tablet detects that the virtual button is pressed, it determines that the annotati...

Embodiment 3

[0207] Figure 10 It is a flowchart of a comment display method provided by Embodiment 3 of the present invention. This embodiment is embodied on the basis of the above-mentioned embodiments. refer to Figure 10 , the comment display method provided in this embodiment specifically includes:

[0208] S301. Receive a screen projection instruction.

[0209] S302. Display the content of the first projected screen.

[0210] S303. Receive an annotation trigger instruction.

[0211] Wherein, the annotation trigger instruction is used to start the annotation function.

[0212] S304. Receive a first annotation signal.

[0213] Specifically, the first annotation signal is used to annotate the content of the first screen projection.

[0214] S305. Displaying the first annotation track.

[0215] Wherein, the first annotation track is generated according to the first annotation signal.

[0216] S306. Perform shaping processing on the first annotation track to obtain a shaping trac...

Abstract

The invention discloses a comment display method, device, equipment and storage medium, and relates to the field of interactive intelligent flat panel, which specifically includes: receiving a projection screen instruction; displaying the content of the first projection screen; receiving the first comment signal, and using the first comment signal For annotating the content of the first screen projection; displaying the first annotation track, the first annotation track is generated according to the first annotation signal; receiving a forward page turning instruction, which is used to control the direction of the first projection screen content to Turn the page forward; display the content of the second projected screen after the page is turned; receive the command to turn the page backward, which is used to control the content of the second projected screen to turn backward; display the content of the first projected screen and the first comment track. Adopting the above technical solution can solve the technical problem that the equipment displaying projection data in the prior art cannot annotate the projection content, realize the annotation for the projection content, and at the same time ensure that the annotation and the projection content appear or disappear synchronously.

Description

technical field [0001] The present invention relates to the field of interactive smart panels, in particular to a comment display method, device, equipment and storage medium. Background technique [0002] In the field of interactive smart panels, screen projection technology, as one of the more and more important applications of interactive smart panels, has been widely used in people's work and study, greatly improving people's work and study efficiency. For example, in a meeting scenario, users can project the content displayed on their laptops to the interactive smart tablet, so that other participants can watch the content through the interactive smart tablet. Through this sharing, the participants can efficiently Participation and decision-making. [0003] However, in the above-mentioned screen projection process, the interactive smart tablet displaying the projection data cannot mark the displayed projection content, which makes the user experience not good. Conten...
