Fannal introduces Hover Sensing; touch-free technology for bacteria-free interactions between people and displays

Hover sensing allows the touch screen sensor to detect and track the movements of a finger that is not in physical contact with the touch screen. The chip can detect and track objects up to a distance of 35 mm from the touch screen. Touch-free technology allows for bacteria-free interactions between people and displays. Hover supports one-finger hover up to 30 mm detection and 25 mm tracking range.
