INTECH Dual User Electromagnetic Interactive Whiteboard Technology Principle
To enrich operations,INTECH dual user electromagnetic interactive whiteboard inherits all the advantages of INTECH M series electromagnetic technology,while innovates the way of interactivity by allowing two users to write on the board simultaneously.
The dual user operating is realized by using two pens transmitting different frequencies,detected by internal coil sensors to calculate the coordinates of pens’ different interacting.
