Description

System for joint reading document and method for the same}

The present invention relates to a document joint reading system and method, which is a document joint reading system and method, which enables documents to be viewed jointly.

Each user owns various types of terminals such as personal computers, smartphones, and tablets, and the user intends to use data stored in the terminal while carrying at least one terminal. As data communication is possible by wired or wirelessly and data communication is possible for each terminal owned by the user, the need to use and share the stored data with each terminal owned by the user without time and place restrictions increases. Became.

Accordingly, a cloud system, which is a system that allows users to share desired information through a virtual storage space and use the information on a desired terminal anytime, anywhere has been developed.

There are various cloud computing methods that can use IT-related services such as data storage, network and content use through the Internet at once. Cloud computing is a combination of various computing concepts and communication technologies such as virtualization computing, utility computing, on-demand computing, etc., and is a single virtual computer or It refers to a technology that implements a service and provides various software, security solutions, and computing capabilities in an on-demand manner by users accessing it.

As the use of such a cloud system is gradually increasing, the case of performing a single document editing operation on multiple terminals using the cloud system is also increasing. More specifically, there are increasing cases in which one terminal reads an electronic document file stored in a cloud system to edit an electronic document, and another terminal reads the same electronic document file to edit an electronic document.

When using such technology, in addition to providing files stored by users, recent cloud systems also provide synchronization services. More specifically, the electronic document file is synchronized between the cloud system and the terminal performing electronic document editing, so that the electronic document file finally saved in the terminal where editing was performed can be read directly from another terminal without the need to perform separate storage. A service that can be edited is provided.

However, the cloud system's electronic document file synchronization service has not yet reached a satisfactory level in terms of user convenience. For example, when a presenter turns a page of a document on the presenter terminal during a presentation, the pages of the same document displayed on the conference participant terminal are synchronized and thus inconvenient.

In detail, it is often necessary to read documents jointly in various cases, such as a meeting for work, a situation where a teacher and learner exchange opinions using a classroom or communication equipment. At this time, there may be a case where a plurality of users have to read a single document, and there may be cases in which the same page is viewed according to the progress of the presenter or instructor.

In the past, printing materials were distributed or the speaker's laptop was connected to a large screen by HDMI to display the screen and viewed together, or by sending it to individual devices via USB or e-mail, calling the page number and passing it over.

This not only causes inconvenience as a large number of users perform such cumbersome procedures in various environments and situations, but also often outputs unnecessary printed data, and causes a lot of loss in terms of time.

In addition, in the situation of conferences, international conferences, and broadcasting/seminars, it is more difficult to jointly read these documents, causing inconvenience to be published and distributed as books or publications.

Therefore, when a presenter opens a channel (room) by designating a document to be distributed, it operates in the cloud, so it is possible to open a channel (room) by logging in to the service regardless of the device and specifying the document on the cloud. The opened channel (room) is given an arbitrary URL, and all invited users can access this channel. The presenter can open and maintain a channel (room) for as long as he wants, and can delete the room at any time. All of this can be done with one click.

Here, the document control authority may include the authority to turn the page of the document, edit the document, enlarge and reduce the document, and change the mouse position. That is, the presenter turns the page of the document being presented, edits it, It refers to the authority to manipulate various document interfaces such as enlarged or reduced display of the document screen or change the position of the mouse positioned on the document during presentation.

Also, depending on the level of the presenter, the authority to control documents may be granted differently. For example, an employee-level presenter has the authority to turn document pages and enlarge and reduce documents only, whereas a manager-level presenter can edit documents in addition to document page turning and document enlargement and reduction for presentation documents. You can give permission to do it. As described above, by giving different document control rights for each speaker level, the presenter can prevent the presenter from controlling the document in all areas.

As shown in Fig. 5, the presenter who has acquired the document control authority determines whether the presentation document can be controlled according to whether the document control authority is obtained through the presentation session, and when the presentation document is controlled, the presenter controls the document. According to the contents, the cloud server 300 synchronizes the presentation.

In the process of accessing the presentation document reading room (S420), the participant terminal 400 used by the participant invited from the presenter accesses the presentation document reading room to view the presentation document. Participants invited by receiving the presentation document viewing room URL from the presenter can access the presentation document viewing room URL through a document viewer provided in advance to view the presentation document.

The presentation document control process (S430) is a process in which the presenter terminal 200 controls the presentation document through the presentation document control screen. Here, in order to control the presentation document, the presentation document control screen is displayed on the presenter terminal 200, and the presenter can control the document through the presentation document control screen. To this end, such a presentation document control screen includes a presentation document display field 10 in which a presentation document is displayed, and an operation button display field 20 that is operated to flip a page of the presentation document forward or backward, as shown in FIG. Will be equipped.
