A tiny screen is mounted on the right hand index finger nail. Software on your touch-operated telephone, slate or computer obtains location information from proximity sensors, and feeds a repeat of the area beneath your finger to the nail-mounted screen. This way, you can always see what is beneath your finger even as you penguin press it.
