Description

Technical Field

[0001] This invention belongs to the field of PPT control, and more specifically, relates to a PPT playback control method, a handheld terminal, a playback terminal, and a server. Background Technology

[0002] In teaching presentations using PCs and projectors, presenters often need to be physically present at the computer, operating it while lecturing—essentially treating the computer as a playback device. This method is not only laborious but also hinders effective interaction between the presenter and the audience. Therefore, a portable device for turning slides and annotating PowerPoint presentations is needed. Furthermore, the intelligence of handheld devices allows for synchronized PowerPoint displays with the PC, enabling presenters to view the current slides and annotations even when their backs are turned or they are away from the screen.

[0003] However, existing technologies only provide one-way control from the handheld terminal to the playback terminal. The playback terminal does not return any PPT information, meaning the handheld terminal cannot view detailed PPT information. Furthermore, existing technologies only provide the function of scrolling up and down PPT slides. In presentations, Q&A sessions, and other situations, it is often necessary to provide detailed explanations of specific slides relevant to the audience, thus causing significant inconvenience. Additionally, while existing technologies offer PPT annotation functions on handheld terminals, such as writing and underlining, they do not differentiate between different drawing functions. This results in unnecessary annotations being permanently written in the PPT, leading to unnecessary saving of annotations or obscuring the actual content on the PPT page, negatively impacting the viewer's experience. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a PPT playback control method, a handheld terminal, a playback terminal, and a server. This aims to solve the problems of existing handheld terminal methods for controlling PPT playback, which only allow vertical page turning and prevent presenters from viewing detailed PPT information on the handheld terminal, thus causing inconvenience.

[0102] In an optional example, the PPT annotation information includes: persistent annotations and indicative annotations;

[0103] Based on the PPT annotation information, synchronize the annotation editing of the currently playing page. If the annotation is persistent, enter the relevant annotation into the PPT page and save it permanently in the PPT; if the annotation is indicative, enter the relevant annotation into the PPT page and clear the corresponding annotation in the PPT after a preset time period.

[0104] In a more specific embodiment, the present invention enables bidirectional interaction between the mobile and PC-based PowerPoint presentations via a server, as shown in the system architecture diagram below. Figure 6 As shown.

[0105] The computer-side plugin uses a pre-edited plugin to retrieve and package PPT information, enabling the mobile device to display all slides and PPT annotations. The plugin's functions are as follows: when the PPT starts playing on the computer, it retrieves all content, the currently playing slide, and annotations and notes for each slide. It then packages each slide into an image and all the retrieved information into a data package. This package is then sent to the computer's processor, which forwards the PPT information to the mobile device via a server.

[0106] Meanwhile, the mobile app plays the PPT through pre-edited functional modules or plugins. Two playback modes are available: one displays only the current page and its annotations, while the other allows previewing any page, displaying the current page, its annotations, and notes. In summary, the mobile app allows previewing any PPT page, controlling page navigation (up / down or jump) and animation playback, selecting any PPT content, zooming in / out to adjust annotation font size, and annotating the current page. Furthermore, the mobile app's annotation function offers two modes: persistent annotations, which use the long-term input and save mode of the annotation input tool, allowing users to enter and save the annotation permanently in the PPT; and indicative annotations, which use the short-term input mode of the input tool, allowing users to enter and delete the annotation within a short time. The specific implementation steps and functions are as follows:

[0107] ① Obtain PPT information from the currently playing PPT on the computer.

[0108] ② The connection between the mobile phone and the server is realized through Socket network communication technology. The user information is logged in on the mobile APP, the server receives and identifies the user information on the mobile phone, and waits for the same user information to be logged in on the PC.

[0109] ③ The PC service program also uses Socket network communication technology to establish an access connection between the computer and the server, and sends the user information logged in on the PC service program to the server.

[0110] ④ When the server identifies users with the same name from both mobile and PC, it will group these users together and create an interaction buffer within that group.

[0111] ⑤ When the PPT is in presentation mode, convert all slides into images and package them together with notes and annotations into a data package and send it to the PC server program. It also receives control information from the mobile device in real time.

[0112] ⑥ The PC program then sends the data packet to the server. The server then forwards it to the mobile app with the same name. The mobile app interprets the information and finally makes corresponding changes on the mobile PowerPoint presentation based on this information.

[0113] ⑦ Similarly, the mobile app packages all information from the PPT, including operation information, and sends it to the server. The server then forwards this information to the PC service program. The PC service program finally forwards the information to the PPT plugin for parsing and response.

[0114] This invention establishes a two-way interactive protocol, upon which functions such as annotation, page selection and playback, page turning, animation playback, and the transfer and viewing of slides and notes can be realized. This invention obtains PPT page information through a pre-edited plugin on the computer, converts the slides into images, and packages them together with notes and annotations into a data package, which is then sent to the mobile device. Simultaneously, the mobile device sends control information to the PC. This is a two-way interactive process.

[0115] The handheld terminal of this invention is a mobile phone terminal, and the mobile APP provides two interface modes to realize two display modes of the handheld terminal. The first mode is the basic interface, which displays all PPT pages at the top and allows users to slide to select the desired playback page. The middle part is the current PPT playback interface, which can be controlled by swiping left and right to turn pages and by clicking to play PPT animation effects. The bottom displays the notes for the current page, and the font size of the notes can be controlled as needed. The second mode is the annotation mode, which displays only the current PPT information and allows users to select a pen for annotation. The pen has two functions: one pen can save annotations permanently, while the other pen automatically clears annotations after a short period of time to ensure that the PPT content is clearly displayed.

[0116] It should be noted that the pen is only a tool for inputting annotations. Those skilled in the art can also choose tools such as the mobile phone's built-in input method to input annotations into the PPT on the handheld terminal interface according to actual needs. Therefore, this invention will not make any special explanation or limitation on this.

[0117] The mobile app of this invention allows for the display and selection of all PPT pages for playback, not limited to page up / down navigation, page navigation by navigation, or animation playback. The mobile app also allows for annotation and viewing of PPT notes on the currently playing page. Furthermore, it employs two drawing tools to input persistent and indicative annotations respectively, to meet different needs.

[0118] After importing the Office add-in, the add-in monitors the PowerPoint presentation's status. If the presentation is in progress, the add-in sends presentation information to a Windows service; this interaction occurs via process messages. The Windows service then interacts with the server using socket communication technology. The server then sends the messages to the mobile device. Similarly, the mobile device's control information for the PowerPoint presentation is sent to the Windows service through the server. The Windows service interacts with the add-in, and ultimately, the add-in reflects this control information on the PowerPoint interface on the computer.

[0119] Figure 7 This is a handheld terminal architecture diagram provided in an embodiment of the present invention; as shown below. Figure 7 As shown, it includes:

[0120] The communication module 710 is used to interact with the server in real time, so as to realize two-way real-time interaction between the handheld terminal and the playback terminal through the server.
