Samsung's selfie camera detects what your fingers are doing while typing on a table and converts that to keystrokes.
Again, there is another weird and wacky technology toy at the 2020 Consumer Electronics Show, an invisible keyboard. Actually, it is really a non-existent keyboard.
Samsung has finally found a positive use for the selfie camera; it detects what your fingers are doing while typing on a table and converts that to keystrokes. Presumably you train it to recognise where your fingers are and what key they would be typing.
It would be fine for a trained typist and it should be to able to keep up with the average two finger typists but how are they going to know where all the keys are when they often take ages to find them on a physical keyboard.
Perhaps Samsung could also add a projector to display a keyboard on the table. It looks like they are solving a problem that doesn’t exist.
