Infrared interactive whiteboard should give top priority when considering purchase an interactive whiteboard not only for its substantial market share, but also its robust advantages.
In contrast to traditional blackboard, infrared whiteboard completely get rid of chalks whose dust will bring health problems. This new style of teaching method stimulates students’ interests and enlivens class atmosphere.
Operating principle
Around the whiteboard, there are pairs of infrared transmitters and receivers and infrared network are created between them. The whiteboard is covered by infrared network, and any nontransparent object contacting the surface will block infrared rays resulting in weakening or avoiding signals. Then the touch location is calculated.
Advantages:
Accurate positioning and high precision
No special pens. Common pen, finger and stylus will work.
Resistance against scratch.
Operating surface and sensing devices don’t have direct contact, eliminating wear and aging problems.
Advanced infrared multi-touch technology for precise location.
Long service life.
Lower cost.
