Factory direct hotline 15503206662 cattle manager Product Overview interactive whiteboard hardware and software, electronic sensors whiteboard whiteboard operating system integration. It is a core component of the electronic sensor whiteboard, stylus, computer and projector components. Electronic sensor whiteboard is a blackboard with a normal size, large-sensitive screen in computer hardware and software support of the work, which acts as a computer monitor and replace the traditional blackboard. Assume the dual function of the electronic stylus pen whiteboard and computer mouse, and its role instead of the traditional chalk. Teacher or student with a stylus directly on the whiteboard (equivalent to the traditional teaching of teachers and students operating with chalk on the blackboard), write or call a variety of software, and then feedback to the computer through electromagnetic induction and quickly through a projector projected onto electronic whiteboard. Whiteboard operating system is present in the computer software platform, which not only support the exchange of information between man and whiteboards, computers, projectors between, but it also comes with a powerful discipline material library and resource production tool library, and is a compatible with a variety of operational intelligence software platform, teachers can freely call a variety of teaching materials or application software on the whiteboard. Set the traditional blackboard whiteboard, computers, projectors and other functions in one, so that teachers use very convenient. Advantages interactive whiteboard supports copying, whiteboard connected directly to the printer through a specific writing on the blackboard whiteboard pen, when you need to print, simply press the print button on the front panel can be realized in color or black and white printing. You can also use as a teaching whiteboard, whiteboard connects to the computer, then the whiteboard area equivalent to a particularly large tablet, you can write in any of the above, painting and instantly displayed on a computer, save the file as a graphic file. This feature generally require a dedicated application support. If by specific applications, interactive whiteboard can communicate through a network with other offices, meeting rooms, network meetings and distance learning. Products interactive whiteboard can be divided into five categories according to the principle: electromagnetic induction, infrared, ultrasound, pressure sensitive resistors, CCD and so on. 1. The basic principle of an optical infrared type; and projectors, is placed in front of the projection screen infrared equipment for receiving and transmitting an infrared signal. Can be adapted to use 20-120 inch projection screen, with the projector screen size changes. Projector projection screen projection screen or wall can be achieved in computer operation on the projection screen. 2. The ultrasonic Rationale: placing an ultrasonic receiving apparatus according to a fixed distance from the two sides of the distribution in the screen, the pen is used to locate an ultrasonic transmitter, ultrasonic waves along the surface of the screen when the pen moving on the surface of the screen, the emitted the receiver is detected by the received ultrasonic wave can be converted from the time T and two receivers. 3. The basic principle of electromagnetic induction: a radio frequency (RF) principle, installed in the sensor white board core, the specific frequency for receiving electromagnetic signals emitted by the pen to achieve positioning. The basic principle of infrared technology type: IR theory, infrared whiteboard surrounding achieve positioning of objects blocking the tube detect infrared light. 5. resistive pressure sensitive basic principles: resistive film technology, pressure sensitive position by detecting the resistance value. 6.CCD basic principles: DVTT technology (CCD optical scanning technology), which is displayed while setting CCD linear array detectors and infrared emitter region two fixed distance, another trilateral setting reflected light reflective film, distributed in two corners were used to detect the blocked area CCD linear CCD reaction of the corresponding region, to calculate the position of the object in the display area, an intersection test positioning.
