Well! While the humble touchscreen has become the standard interface for most smartphones, and capacitive displays make it a painless experience, the folk at start-up Qeexo think things could still be improved.
They developed a technology called FingerSense that could add even more functionality. Essentially, by using a small acoustic sensor, it measures the vibrations as objects tap the screen, and can tell the difference between them. So, for example, a knuckle tap could be used for “right-click.”
The tech is able to spot the difference between materials, too, so even when no finger is involved, it can register input, a great assistance to those with longer fingernails.
The fun doesn’t stop there, though, with the demo video that you can check it below, Demoed on a Galaxy SIII with a modified display, able to register stylus input, even without official support for it.
