Most interactive flat panels for education use infrared (IR) technology that embeds the touch overlays in the bezel. This produces an invisible grid of IR beams and sensors that detect touch when the plane of the grid is broken by touch.
Although an excellent multi-touch solution, IR technology has several issues:
• Solid objects, resting a palm, or other obstructions can block the IR beams.
• Performance can be affected by extremely bright sunlight.
• Touch can be recognized without having to make contact with the surface, which isn’t always intuitive.
If you find the ActivPanel to respond too sensitively, please ensure that the connected computer is set to the optimum resolution for your model, and (where applicable) you have paired the ActivPanel digital pen.
Using the ActivPanel digital pen as a stylus, without pairing it, can cause the ActivPanel to treat it as a touch input because it breaks the IR grid before it touches the surface. Pairing the ActivPanel digital pen enables the use of both left and right click, and allows the ActivPanel to distinguish between hovering (digital pen not touching the surface) and writing (digital pen touching the surface).
