Not only do our sensors know where the fingers are, they also know how much force is applied to the glass. This opens up new possibilities for your application by controlling the operation via pressure, for example an amount of intensity.
But IMPAsensitive can also detect panic reactions – for example, if a stronger pressure is applied as a reflex or the hand is suddenly taken from the glass.
There are no limits to your ideas. Switching functions, for example between upper and lower case, but also between different operating levels, are just one example.
