Bilateral lamps Desktop Visualizer type of physical Booth: This is the most common type of physical booth. Bilateral lamp used to adjust the desired light intensity physical booth, adjust the background compensation light flexible, easy to best presentation is displayed items. Unilateral light Desktop Document Camera: This is the more common type of physical booth. Unilateral lamp used to adjust the desired light intensity physical booth, to facilitate the best presentation is displayed items, different positions stand unilateral light varies, but does not affect the results. LCD monitor as a kind of stand options, easy to monitor the position of the presenter booth items. Floor Separate physical booth: This document camera is designed to save storage space. Because of the separation plate to make physical booth enhanced portability, moving within a small range of very convenient. Portable document camera: This document camera for users that require special portable design. Usually less due to high demand, high production costs, the price is relatively high. A typical use of physical stand now, with the wide spread of multimedia teaching equipment in schools, educational presentations designed specifically for physical product in a booth in this region has been more widely used. But some people are still lack of understanding, the following, we introduce three typical use of physical booth, to show its actual application scenarios in education, hoping to give users more intuitive understanding. 1. take advantage of the physical kind booth projection function can not scan images directly projected image screen, very convenient. Further, the exemplary process may be directly projected experimental operation. For example, observed with a microscope in biology class experiment can be carried out directly on the physical booth demonstration operation, the students each position can be clearly seen; in addition, during the demonstration test of chemistry, physics and other disciplines have intuitive features, through physical booth careful observation can be intuitive, to bring students the deepest impression. 2. On the physical booth directly writing on the blackboard blackboard direct projection booth in kind, very clear and intuitive. The industry has done a test: the same example, with chalk writing on the blackboard, computer gradually display, in-kind classic is tinted projection booth + write, these three means of comparison, finally, the method of the physical effects of a combination of performance and projection booth than the other two excellent. Because chalk writing on the blackboard behind the students see; computer displays like motion pictures, the students can not keep thinking; third method than the computer display a waste of time, but the actual effect is very good. Therefore, the actual situation of teaching, the use of physical booth and direct manner compatible blackboard explaining the math, physics and other disciplines focusing on examples of the thinking process, is a good way of teaching. 3. Physical booth old slide projector, slide kind booth can accumulate a lot of old school slide, slide again, "Please glow Spring", the kind of backlight booth opened, you can easily projection of these data, and , amplifying the effect higher than when using multiple projectors demonstrate the effect more clearly. In addition, now increasingly focused on interactive teaching, usually can have the use of physical projection booth to the student's work on a blackboard, the teacher gradually correct the problem solving process for commenting, teaching effectiveness stronger. Through the introduction of the above points, the user may be able to stand the physical products have a certain understanding. With the continuous development of information technology in education, and continuously improve customer awareness of physical booth products will have greater development in the field of education. -4-Axis machining chuck lathe chuck shorten the processing cycle tower line - which patrol the line shall comply with safety regulations?

Note With the continuous development of information technology in education and the deepening of education reform, teachers' teaching methods are constantly changing. Many schools in the promotion of multimedia assisted teaching, before those high-end physical booth also gradually into the ordinary classroom into. However, comparatively speaking, after all, a new kind booth teaching equipment, consumers also understand it is not very deep. In fact, physical booth during the installation and operation of which there are many details that need to know, so as to allow the product to achieve the best results, but also in order to effectively protect the product. Today, the era of network projector on for you a brief introduction, consumers can serve as a reference. 1, physical booth for teaching, pay attention to ensure a suitable distance between it and the projection screen while adjusting the focus, to ensure that the system can have the best display projection, all other devices should be placed and easy to wire without affecting the people watching place. 2. When using the remote control physical booth, should try to make the remote control transmitter physical booth at the mouth of the remote host receiving port, in order to achieve higher operating sensitivity; if you find the remote control does not work, then you first need to check the remote control whether the battery is charged, then sent to the remote control transmitter port and in-kind booth host remote control receiver port wipe clean to avoid dust affect the remote control work if the remote control still does not work at this time, then re-confirm the current Are you using a remote control and physical booth belonging to the same model. Professional HD video Cinda preferred booth at Showcase factory 3, at the beginning of the use of physical booth, the user should be based on different environments, to stand for what kind of operating parameters necessary adjustments. For example, try to use the projector at the projection material, in order to document camera focusing and zooming and positioning of the projected image; Second, we must use the environment to the light conditions to adjust the brightness of the projection booth in kind, contrast and color; the third point , but also to adjust the scanning frequency to adapt to different sources, eliminate unstable image, only prepare the above, in order to make physical booth in top working condition. 4, the choice of physical booth, in addition to interest resolution CCD technology such indicators, but also pay attention to the detection of a number of other indicators, such as black and white color reversal, reversing positive and negative film, the quality and quantity assist lamp sources, How much input and output ports, whether the serial interface, whether an infrared remote control functions, etc., of course, choose these indicators are licensed under the premise of funds carried out.

SXGA (1280 × 1024), also known as 1.3 million pixels, XGA (1024 × 768), also known as 800 000 pixels, SVGA (800 × 600), also known as 500 000 pixels, VGA (640 × 480), also known as 300,000 pixels (350,000 refers to the 648 × 488), (352 × 288), also known as 100 000 pixels.
