Digital blackboards allow a computer screen to be projected onto a surface for teaching purposes. There are different types, including large format boards controlled by touch, portable boards using a laser pointer, and tablet monitors. The technology behind digital blackboards can use electromagnetic, infrared, or resistive methods to detect input on the board and send it to the connected computer.

2. I am going to speak aobout: Definition Types of digital blackboards Technology of the digital blackboards

3. Definition: The digital blackboard consists in a computer connected to a video-proyector, that projects the image of the screen on a surface, and you can control the computer.

4. Types of digital blackboards and Advantages. Digital blackboard of big format: You can control it with a finger.

5. Portable digital whiteboard: You can control it with a laser pointer

6. Tablet Monitor You can control it with a tablet monitor

7. Technology of the digital blackboards Electromagnetic: using a pointer, there are magnetic sensors across the screen to react and send a message to the computer when they are activated by contact with the pointer. Infrared: The marker pure infrared signals when in contact with the surface. Resistive: the panel of the board is composed of two separate layers, the exterior is deformable to the touch.
