To learn how the interactive whiteboard, they succeed.
There are four main technologies used for the SMART Board to take the breath of each device can be. If possible, it is understood, will be able to take the lion's share of choosing his work.
1. Interaction with the resistive technology, the surface of the material consists of two thin slate-sensitive. Do not touch and have a minimum distance between them. When a pointing device such as a finger or pen is pressed on the board, the two sheets touch at that point. The team is able to see the position of the pointer.
2. Electromagnetic interaction in assets and liabilities are classified electromagnetic solenoid. The active nature of the interaction between them and the Board of Directors of the spring is also magnetic. In case of contact, which can make sense of the situation and transmitted to the computer? In the past interactions, only the bar magnet and its location can be transmitted to the computer via radio.
3. Optical interaction with this technology, the SMART Board emits infrared radiation and detects the position of the cursor. Infrared is activated when the pen touches the surface of the table. Then recognizes the position.
4. Ultrasound interaction is two types of this kind. One in which the interactive whiteboard has ultrasonic sensors to detect the position and the other in which the mouse is equipped with ultrasonic sensors. The first technology, there are generators and receivers of ultrasonic waves to every corner of the table. The location is what the oppression of the waves through touch. In the second sense of the common technology of ultrasound and position the pointer on the radio to the computer.
