Your Hand Will also be Your Smartphone Very Soon
Using a special camera that combines high-speed vision and two rotational mirrors, Masatoshi Ishikawa and his team at the Ishikawa Oku Laboratory, said that they have found a method to project a device's display screen or keyboard onto the palm, or any other surface, so that people can operate it remotely in their home or office, ABC News reported.
Ishikawa said that the technique can detect movement of a 3-D object every two milliseconds, in other words, the high-speed vision allows the program to track moving objects, so users would be free to walk with the phone image in palm, without the display ever shifting.
Also the ultrasonic wave emitters are beamed by the computer system, so that user feels the keyboard pressing against their skin, without anything being in their hand.
Ishikawa said that the sensation is the equivalent to a 3-gram or 0.1- ounce object.
