Hebei Hengshui Commodities expert Whiteboard Meeting whiteboard

z factory direct hotline 15503206662 cattle Manager product overview interactive whiteboard hardware and software electronic sensor whiteboard whiteboard operating system integration. Its core component consists of electronic sensors 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. Electronic stylus pen assume the dual function whiteboard and computer mouse, and its role to replace the traditional chalk. Teacher or student with a stylus directly on the whiteboard (equivalent to the traditional teaching of teachers and students operate on a blackboard with chalk), write or call the various software and feedback to the computer through electromagnetic induction and speedy adoption of the projector is projected to electronic whiteboard. Whiteboard operating system is present in the computer in a software platform that not only supports the exchange of information between man and whiteboard, computer, projector between, and it comes with a powerful subject material library and resource production tool library, and is a Compatible operating smart various software platforms, teachers are free to call a variety of teaching materials or application software on the whiteboard. Whiteboard set traditional blackboard, computers, projectors and other functions in one, so that teachers use very convenient. Advantages interactive whiteboard also support the copy, the whiteboard directly connected to the printer, carried through specific whiteboard pen writing on the blackboard, when you need to print, simply press the print button on the panel to achieve color or black and white printing. You can also use as a teaching whiteboard, whiteboard connects to the computer at this time is equivalent to an area of ??special whiteboard large tablet, can be above any writing, painting and instantly displayed on a computer, save the file as a graphic file. This function generally requires a dedicated application support. If by specific applications, interactive whiteboard can communicate over the network with other offices, meeting rooms, network conferencing 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. Optical Infrared fundamental principle; and projectors, infrared device placed in front of the projection screen for receiving and transmitting infrared signal. It 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 realized in the operation of the computer on the projection screen. 2. The ultrasonic Rationale: Place two ultrasonic receiving apparatus according to a fixed distance on both sides of the screen profile, the pen is used to locate a ultrasonic transmitter, ultrasonic waves along the surface of the screen when the pen moving on the surface of the screen, the emitted a receiver to be detected, by the received ultrasonic wave can be converted from the time the pen and two receivers. 3. The basic principle of electromagnetic induction: a radio frequency (RF) principle, install the sensor within the white board core, specific frequency signals sent by receiving electromagnetic pen achieve positioning. The basic principle of infrared technology formula: IR theory, infrared whiteboard surrounding achieve positioning of objects blocking the tube detect infrared light. 5. resistive pressure sensitive basic principle: resistive film technology, pressure sensitive positioning by detecting the resistance value. 6.CCD basic principles: DVTT technology (CCD optical scanning technology), showing one side of the line CCD array detector set and two fixed distance infrared emitter region, and the other three sides setting light reflecting film, distributed in two corners detect the blocked area CCD linear CCD reaction of the corresponding region, the calculated position of the object in the display area is an intersection test positioning.
