Depending on which series the SMART board belongs to, 600 or 800, it functions through either resistive technology or through infrared optical imagery technology. Resistive touch technology responds to pressure placed on the board's surface. Infrared technology senses the touch through light interruption.Continue Reading
The 600 series SMART boards utilize the same resistive technology found in some smartphones, digital cameras and computers. Resistive technology screens have two surfaces that are coated with conductive material. The surfaces are separated by a pocket of air. When the screen is touched, pressure from the touch causes the two surfaces to meet and respond. The computer then responds to which area of the board's surface is touched.
The 800 series SMART boards utilize the more accurate optical imagery technology. Inside the SMART screen are infrared imaging sensors that also emit infrared signals. The surrounding surface is covered with retro-reflective tape. When the surface of the board is touched, it interrupts the light returning to the sensor from that angle. The computer senses the area that was touched through the precise angle.
Both the 600 series and 800 series SMART boards detect finger or pen point touches and utilize SMART notebook learning software. The 600 series is less reliable when dragging items across the screen because of its reliance on consistent pressure. The 800 series is capable of detecting multiple user inputs, and its technology is more reliable for controlling items on the screen.Learn more about Office Supplies
