Interactive Whiteboard
IW The interactive whiteboard is a large touch screen that works as a part of the system which also includes a computer and a projector. With the help of the projector image computer desktop is projected onto the surface of the interactive whiteboard. In this case, the board serves as the screen. With the projected image on the board, you can work, make changes and notes. All changes are recorded in the appropriate files on your computer, can be saved and subsequently edited or copied to removable media. In this case, the electronic board operates as an input device.
Board can be controlled using a special stylus and using the touch of a finger. It depends on what kind of technologies have been used in the manufacture of boards. Communication boards and computer-sided, and a finger or a pen (stylus pen) interactive whiteboard acts as a mouse. Currently interactive whiteboards are widely used in classrooms of schools as a means of computer support lesson in the training center, meeting room. When working with an interactive whiteboard, the projector can be replaced by a document camera, which gives the opportunity to further diversify the learning
Types of electronic whiteboards. Interactive whiteboards are the forward and reverse projection, and are distinguished by the type of installation projector. When the projector is a direct projection to the board, for rear projection - the board. Most interactive boards - boards direct projection. To the projector are not interfered with the work of the teacher and the students, it is recommended to work with the board to use Ultra-projector, which can be attached to the mount directly above the board. Interactive whiteboards are active and passive.
The board by using electromagnetic and resistive technologies must be connected to the computer and power supply wires. On the boards created using electromagnetic and laser technologies can only work with a special electronic marker. Boards based on resistive, ultrasonic and infrared technology support work as a special marker, or any other object, such as a finger. Infrared and ultrasonic technologies are often combined. Board, produced on the basis of micropitting technology to connect to the network or computer does not need. The main working tool in the design of such a board is the stylus, which transmits the data to a computer using the built in in a Bluetoothtransmitter.
