Talk to the hand

 

Sir, – There is another weird and wacky technology toy at the 2020 Consumer Electronics Show in Las Vegas, 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 we 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.

I’m not sure what it will type for the two-fingered gesture I am thinking of. – Yours, etc,
