From Science Fiction to the Lab: Feelable Holograms


From sci-fi to science lab: Holograms you can ‘feel’

Scientists have developed a new 3D imaging technology that can be seen, heard and even felt without a VR or AR headset.

After in «Star Wars» talking holograms have been shown and have become a popular aspect of many science fiction films. However, a team of engineers from the University of Sussex has created a prototype device that can simultaneously generate visual, auditory and tactile content..

From Science Fiction to the Lab: Feelable Holograms

At the heart of its work are focused ultrasonic waves that very quickly manipulate objects (in this case, a ball) in three-dimensional space to form an image in a small box with arrays of tiny speakers..

In fact, the system moves the particle using acoustics and illuminates it with red, green and blue light, controlling its color during fast scanning. Since changes occur in less than 0.1 seconds, the human eye perceives all changes as one solid image (like in old televisions).

Since the system works thanks to sound waves, it allows you to hear and even feel the hologram, which makes it as realistic as possible..

Although at first glance the technology seems entertaining, the developers claim that it has enormous potential in the field of computing and biomedicine, since it allows you to manipulate a substance without tactile contact..

In addition to scientific institutions, commercial organizations are also working in this direction. Samsung filed a patent last year for a display that projects a high-quality 3D image into its surroundings that can be viewed from any angle..
