Tingly projections make beamed gadgets come alive

Tingly projections make beamed gadgets come alive: Ishikawa's system detects and maps the position of an object 500 times per second and projects an image onto it. It automatically controls a camera's pan and tilt angles to ensure it is locked onto an object no matter how fast it moves...

...The information about the exact location of your hand and the orientation of the projected keypad is fed to a second system, called the Airborne Ultrasound Tactile Display...

The sensation on the hand is generated by sound beamed by 2000 or so ultrasonic wave emitters... The carefully timed and directed sound beams can make any spot vibrate within a given cubic metre.
