How does it work? Well, Wacom‘s EMR technology is based on electromagnetic resonance. With the help of sensors, an electromagnetic signal is detected, which combined with an alternating grid pattern generates a magnetic field. The magnetic field is reduced to approx. 5 mm above the surface of the glass and can thus register the position of the writing instrument as well as the angle and pressure. In other words, it’s magic!!
Please note that EMR technology is not compatible with IOS but works with most other devices (full details are in the document below).
