Description

Synchronization indicating location briefing system and method thereof

The present invention relates to a synchronization indication position briefing system and method thereof, and more particularly to a method for synchronizing a light point coordinate indicated by an optical indicator on a developing plane of a projection module with an indication mode of the same light spot to other The presentation system and the method thereof on the imaging plane of the projection module effectively enable the remotely located presentation system to have a clear optical indication effect when synchronously playing digital content by means of synchronized remote control technology.

According to the general business or academic environment, it is very common practice to display digital content through the projection system. In the briefing, the briefer usually uses the briefing pen or computer mouse to control the flow of the briefing. Content, if the paragraph to be explained needs to be instructed, the briefer will also use the laser beam or the cursor driven by the mouse as an indicator to enable the participants to have a clearer understanding of the briefing. In addition, with the rapid advancement of technology, long-distance video conferencing is also emerging in business situations, while cameras providing remote video capabilities transmit local-end images to remote participants. In addition, the locally broadcasted newsletter data can also be transmitted synchronously so that the far-end participants can participate in the conference without being restricted by the long-distance space; however, the remotely located participants can usually only view from the display of the computer or television. The screen of the newsletter that is played by the local reporter, if the local briefer uses the optical When the indicator indicates the content of the briefing, the remote participant cannot see the position indicated by the briefer on the display. If the content indicated by the optical indicator cannot be effectively explained by the briefing person's dictation, the remote end Participants will have the phenomenon of "duck listening to the thunder", so that they can not effectively integrate into the discussion of the meeting or understand the focus of the local briefings, and even more, the remote participants may miss important The discussion made a different conclusion from the local participants, thus losing the meaning of the discussion at the teleconference.

Inventors of past patents have found that the shortcomings caused by teleconferencing have been improved, such as the "Light Point Remote Synchronous Display System and Method" of the Republic of China Patent No. I431525, which provides a local laser indication.

And the remote end system plays synchronously; however, the mark symbol S generated by the system post-production system is displayed on the playback screen of the remote end system, and since the mark symbol S is displayed on the play screen together with the image data system, it is easy The readers at the far end mistakenly believe that it is part of the newsletter and cause confusion in reading or comprehension; in addition, the number of local briefers is within the number It must be stored by computer, and then transferred back to the computer for data transmission through the projection system. In today's "Action Office" appealing, the system's briefers need to carry computers and projection systems, which often makes the convenience greatly reduced. Therefore, how to effectively integrate the computer and the projection system, and then use the remote synchronization control technology to enable the remote participants to clearly see the position of the optical pointer and clearly understand the briefer as if they were on-site.
