Interactive 3D Holograms You Can Touch & Feel

Whilst holographic technology is not yet widely available to the general public, it's usually only a matter of time before state-of-the-art technology becomes the standard. It's also true that the evolution of technology moves at such a fast rate that not much times passes before standard technology becomes outdated.

Holographic technology has already been developed and whilst it is generally only seen on television, it won't be long until holographic devices, such as television sets, mobile phones, tablet PC's and watches are the norm. That is, until holographic technology becomes outdated and we move on to the next revolutionary step in our technological development.

Now researchers at the University of Tokyo and the Nagoya Institute of Technology have come up with a new interactive type of holographic technology which they have named Fairly Lights. Fairly Lights technology uses a femtosecond laser which emits pulses at a quadrillianth of one second (a femtosecond). The pulses stimulate matter in order to form voxels (light emitted by plasma) which are used to draw 3D holograms.

According to the researchers, "Shock waves are generated by plasma when a user touches the plasma voxels. The user feels an impulse on the finger as if the light has physical substance."

In other words, whilst the 3D objects are essentially only made of light and are therefore not tangible, the impulse which is generated by the plasma when it's touched gives the user the illusory experience of feeling the objects as though they are really there. Whilst the holograms are currently only very small, measuring in at 1-cm squared, the researchers have stated that they are indeed scalable.
