Title: Multi-source multiple documents comparison display (presentation or discussion) system

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention is a multi-source, multiple document comparison display system for presentation or discussion, which is installed in a host computer and displayed on a public screen as a multiple document comparison interface using the computer&#39;s auxiliary display system. 
     2. Description of the Prior Art 
     In recent years, different types of application equipment and software have emerged due to rapidly developing network technologies and high transmission rates. With conventional systems gradually being replaced by interactive technologies such as the Internet and computer equipment, a conventional projector for documents projected to and displayed by a single projective machine is limited in its usage, and provides neither interactional functions nor real-time connection to another device. Such a conventional projector system or device also fails to provide a simultaneous display of related information. 
     A conventional projector system or device is an inconvenient tool which fails to promote interaction or coordinate networks simultaneously and is unfavorable with regard to data being updated or downloaded directly thereto, so that any new, updated version of software must be downloaded to a private computer first and hence requires extra time or work. 
     SUMMARY OF THE INVENTION 
     The object of the present invention is to provide one multi-source, multiple document comparison display system for presentation or discussion as a computer&#39;s auxiliary display system. The system is installed in a host computer (Host) for connecting clients, and the multiple document comparison interface system is immediately displayed on a public screen. 
     Another object of the present invention is to provide a multi-source multiple document comparison display system for presentation or discussion with a document collection stage and a comparison display stage, which includes the following stages: 
     (1) Document collection stage: The comparison interface is selectively split to and arranged as a number of different quadrants and displayed according to multiple documents. The documents may be transmitted from different mobile sources, devices or carriers via a cable network or a wireless network with the multi-source multiple documents comparison display system for presentation or discussion being activated by a host computer (Host); 
     (2) Comparison display stage: The distinct thumbnails for compressed documents are arranged and displayed on a public screen and provided with control buttons, each of which can be clicked to check one document&#39;s content individually. 
     The data transfer devices which facilitate multiple and real-time sources of documents comprise: 
     Document Camera (DC) providing immediately shot data such as a document and an object; 
     Tablet personal computer (PAD) or notebook computer for documents or data in any page being immediately transported to a host computer via a cable network or a Wireless Local Area Network; 
     Smartphone providing real-time data via a Wireless Local Area Network; and 
     Mobile device used to transport documents or data which can be received by a host computer and displayed on a public screen. 
     A further object of the present invention is to label information which is necessary to document comparison or presentation on a document in the system, and simultaneously offer a user&#39;s mobile device (or host computer) a mechanism of real-time voting. 
     These features and advantages of the present invention will be fully understood and appreciated from the following detailed description of the accompanying Drawings.
