The third generation of interactive laser pen, is composed of a locator and laser pen, can directly use the laser pen can write remote monitoring picture, also can directly use the laser pen in the projection screen or in the projection on the metope of writing, but also can operate a computer.
Introduction to the electronic teaching whip system
The electronic teaching whip system is a new type of computer information input and control system.It adopts the highlight of the semiconductor source to indicate the target location.Real-time analysis of target point coordinates using image sensing and hardware and software signal processing technology;Using the microcontroller to modulate the light pen, the control signal can be sent simultaneously.Communicate with computer, coordinate correction and signal analysis using computer's processing power, and realize interactive operation with computer.Based on the above characteristics, after using this system, using the system to provide the special light pen can not only achieve all of the mouse operation, but also can realize the function of some ordinary mouse cannot be achieved, such as virtual writing, etc.
The basic function of electronic teaching whip
An ingenious product of the latest patented technology.It can turn any normal projection screen into a high-resolution touchscreen.Using the light pen provided by the product, the speaker can operate the computer directly on the screen, which is more intuitive and faster than using any existing mouse.You can also write markers anywhere in the display area without needing to click on any menu commands.The software of the system also provides a virtual whiteboard function, which can replace the ordinary white board for writing and drawing, and the contents can be saved, replayed, printed and so on.
Industrial application and functional characteristics
In the press conference, product exhibition meeting, report meeting, teaching and other activities, the use of projector is more and more frequent and irreplaceable.However, there is a great drawback to using the projector, that is, it can not operate the system flexibly.We often see the speaker struggling to step down and groping for the keyboard or mouse to turn the page or open a picture or document.Sometimes need other people to cooperate work, explain the often need to make some mark off the cuff, computing, writing, which often need to provide another to prepare a whiteboard, this not only takes up space, and is not very flexible, which not only greatly affect the efficiency and effectiveness of the meeting or class, the speaker and the audience's emotions are affected.
If you use the sky painting electronic pointer, you will make a fundamental change in the situation.Once connected, first of all, the speaker is almost don't have to be concerned about the existence of the computer, because in the hands of the wireless light pen can be directly in front of the screen to complete all of the mouse operation, such as open the file and run the program object, drag the icon, click on the menu, the picture page and so on.
When need to write comments or picture, will don't need to roll up screen or in addition to prepare a whiteboard, as long as written in the products provided by a kind of using light pen, direct measurements can be written on the screen.The pen of green laser can be arbitrarily selected, all that is done is to click on the palette.The contents of the whiteboard can be stored on disk, replayed, remote playback through the network, or printed directly.Given the actual need to use, a special button is provided on a light pen, and any time you press this button, you can instantly mark anywhere on the Windows desktop.
Compared with the existing large-screen touch screen and remote mouse, this product has the following characteristics:
Intuitive human-computer interaction greatly improves working efficiency
Because of using light pen is on the projection of the projector screen for the fully functional, but also can do it "refers to the income", can almost forget when using computer, which is intuitive and convenient, greatly improved the work efficiency when using the projector, operability, flexibility and interesting.No assistants will be needed when the lecture is reported on the podium.This is the fundamental advantage of the product.
Applicable to any projection screen
Using the skymap system to turn any projection screen into a touch screen, the size of the screen has almost no limits in the normal range of projections that any similar product can't do.
Applicable to any PC machine
The system's signal receiver can be connected to a serial port or USB port of any standard desktop PC or laptop PC.
Easy to carry
The electronic teaching whip products are small, light weight and convenient to carry.
You don't need any supplies
When using the sky painting system for whiteboard writing, the writing is virtual and does not require any actual color pen, so it does not require any consumables except for the battery.Light pen normally USES very little power.
The connection is convenient and easy to operate
Due to the use of special photoelectric sensors, do not need to install any sensor on the screen, as long as the host when installation box placed near a projector or fixed installation, such as the ceiling, with laser beam auxiliary position can be adjusted.Basic functions are easy to use and easy to operate.
Instant annotation
Using the skydrawing system, the light pen can be used at any time, anywhere on the projector screen (but the information is not saved).
Excellent performance and low price
The work of this product and projector not only realizes all functions of the existing mouse and touch screen, but also provides some functions and features that the existing technology cannot provide.At the same time, the high cost is avoided because of the special technology.
