The new holograms are touch manipulated and will potentially take laser technology to a whole new level.
A group of Japanese scientists have created holograms that are touchable and can be controlled even by fingertips.

Researchers used Femtosecond laser technology to manipulate three-dimensional virtual objects while they are in the mid-air. This laser technology emits high frequency laser pulses that last just a fraction of a second, exactly one millionth of one billionth of a second and respond to human touch.
The latest discovery has opened up a new avenue in laser technology which has implications for many fields including entertainment, medicine and architecture. The big plus is the laser is touchable. Otherwise, current technology is highly reactive and unsafe for touching. The touching ability will take enjoyment to a whole new level and will make people feel that they are actually in a real situation.
“You can’t actually feel the videos or pictures, and although you can project a video, you cannot interact with it by touching it,” said lead researcher Dr Yoichi Ochiai of Tsukuba University. “So, if you can project an image in a three-dimensional form, and if you can touch it, then you can make something where you’ll think that there actually is something there.
“People’s daily lives would change if we use a bigger laser in a bigger space where people can interact with it, and to see how it can be used in a situations where three dimensional communication is necessary such as a construction site or in the medical field.”
Experiments to create touchable holograms have been done before but they proved harmful and the laser beams burned human skin when they were touched.
According to PulseHeadline, researchers are hoping to improve the technology and will possibly create a computer keyboard that can beam light onto person’s lap and allow the users to virtually touch each other during a video chat or while playing a virtual reality game.
