MOTION SENSORS
On-off buttons seem easy to replace with a bodily interface. But what are we going to do with touch screens and keyboards of vending machines, ticket boxes and ATM's? Motion sensors are available for typing without touching the keyboard. An example is Leap Motion. The motion sensor reads the fingers and creates a virtual skeleton to understand what movements the hands and fingers are making. The sensor virtually understands which button you press with which finger. These gestural interfaces can become the standard for ATMs, vending and ticket machines. It will make us feel like being in Steven Spielbergs' movie Minority Report in which Tom Cruise controls his computer by moving his hands in the air.
