Problems solved by technology

However, due to the performance of PDA software and hardware and the functions that can be developed on the software platform are very limited, it can only realize some basic functions provided by demonstration software such as page turning and display mode switching, and generally wireless projectors are relatively expensive. The primary use cases for these demonstration devices are also not very popular

Embodiment 1

[0036] Such as figure 1 . The control terminal is a removable tablet computer A with a touch screen and a stylus and is equipped with a control terminal program. The demonstration terminal is a desktop computer host D and a display E connected to it. The mobile tablet computer A has a built-in Bluetooth C1. Demonstration The host computer has a built-in Bluetooth C2.

[0037] Among them, the control terminal program installed on the mobile tablet computer is developed by Visual C++. It has demonstration interface display and plotting input graphics box, lecture note text box, line drawing type selection frame, control buttons, Bluetooth communication module, and imports package There are control and bluetooth interface access function library files provided by the external program interface function provided by the demonstration software. The program structure is as image 3 shown in the dotted box.

[0038] Among them, the control of the external program interface functio...

Embodiment 2

[0043] Such as figure 1 . The control terminal is a removable tablet computer A with a touch screen and stylus and equipped with a control terminal program, and the demonstration terminal is a desktop computer host D and a projector F connected to it and a projection screen G projected by the projector F (computer host Indicated by the dashed box after D).

[0044] The removable tablet computer A has an external Bluetooth C1, and the demo computer host D has an external Bluetooth C2.

[0045] Wherein, the control terminal program that mobile panel computer A is equipped with is the same as that in embodiment 1.

[0046] Install Microsoft Office software on the mobile tablet.

[0047] Its demonstration process is as described above. The demonstration result is projected to the projection screen G through the projector F and displayed on the projection screen G.

Abstract

A slide projector showing system capable of wirelessly transmitting plotting information is characterized in that a control terminal is a movable panel computer which comprises a touch screen and a touch pen and is loaded with a control terminal program; a showing terminal is a display or a projector connected with a host computer and a projection screen matched with the projector; the movable panel computer has a built-in or external Bluetooth; and the host computer has a built-in or external Bluetooth. The control terminal program is in real-time response to plotting or marking of a speaker on the showing interface; and the plotting information can be wirelessly transmitted to the showing interface of a showing computer through the Bluetooth, and the identical plotting pattern can be synchronously displayed on the showing interface. Therefore, the showing screen has the function of an electronic whiteboard and can be operated movably in the field.

Description

technical field [0001] The invention relates to a slide presentation, in particular to a slide presentation system for wirelessly transmitting plotting information. Background technique [0002] Slideshow presentations have replaced traditional blackboard or whiteboard explanations in many occasions. They have the characteristics of rich pictures and texts, easy use of various multimedia technologies, large amount of information and high speech efficiency, but unlike blackboard writing, they can be modified arbitrarily, handwritten and marked in the explanation. Lack of vividness, real-time interaction, randomness and other characteristics, especially the classroom teaching in schools sometimes even seems dull and boring, which restricts teachers' improvisation, and students are also at a loss for turning pages like a revolving lantern. [0003] At present, although there are some improvement methods, such as using blackboards and slide lamps together, one of the two must be...
