       [0002]    Recently, the touch panel and technologies are widely used in consumer product. The touch-control to the virtual object within the display increases convenience. Especially, it allows the user to control the image for enlarging, shrinking and rotating the virtual object by the user finger. 
         [0003]    In general, the presenter or the teacher employed blackboard or whiteboard to write down his points during the meeting or teaching. The listener should take note by hand writing. It is not convenience to the user at all. Currently, the computer is the typical tool during the teaching and meeting for presentation. However, the computer and the projector should be prepared before the teaching or the business presentation, and followed by projecting the information onto the screen. The one who presents the information can write none information on the screen, it is inconvenient to the user. A blackboard or whiteboard is required to fulfill the requirements for the presentation. The user needs many equipments and the setup of device is complicated and time-consuming. 
         [0004]    Therefore, large-size electronic panel is development to replace the white board. The computer output the information onto the display of the electronic panel, which is so called the electronic whiteboard. An electronic pen is provided to allow the user to write the text onto the display, even store or print out the text and take note. Some of the electronic panels offer the function to record and display the image file. 
         [0005]    However, there are some drawbacks to the electronic panel, for instance, the display panel size is limited, and no one can write information outside the screen. The user should erase the former information for writing further information. It is not so convenient. If the presenter or teacher requires opening several files at the same time, the user should switch among the files frequently by clicking icons. Further, the current system cannot offer dual way activities between the student and the teacher for the teaching and presentation. 
         [0006]    What is required is a more convenient system. 
       SUMMARY OF THE INVENTION 
       [0007]    In view of the aforementioned defects of the conventional method, the present invention discloses a multiple touch presenting system and method of the same.
