To get a better idea, it works in the same way as that of a camera’s shutter button, where you can “feel” a bunch of layers now whenever you press on your smartphone’s display, letting your finger(s) feel the actual sensation of how much pressure you actually apply to the display.
While the demonstration model at KDDI’s booth paraded just a couple of haptic layers, Kyocera has confirmed that they are able to offer up to seven layers on the entire screen’s surface. No idea on how soon can we see this technology be implemented in future smartphones and tablets, but we are already salivating ahead in anticipation.
