Heard an interesting talk today by one of the other interaction designers in the BBC, he had a background in designing for mobile devices and was mentioning what the future was in this field.

Nokia have apparently filed a patent recently which uses ultrasonic transducers to emit sound waves which are then reflected back when fingers and hands block the path. This essentially means that the phone can recognise hand and finger movements in three dimensional space Minority Report style!
