Scientists out of Britain have managed to create realistic 3D holograms that can be seen with the naked eye, heard and even felt.

A team of scientists working at the University of Sussex in southern England has managed to use technology to create a prototype called Multimodal Acoustic Trap Display (MATD). This prototype has the ability of "simultaneously deliver visual, auditory and tactile content". This is done through using sound waves or "acoustophoresis" that move and manipulate particles to form an image.

The team spoke out about how they achieved this, saying "Our system traps a particle acoustically and illuminates it with red, green and blue light to control its color as it quickly scans the display volume." Due to the system being developed with sound waves, it allows the hologram to not only be seen but also heard and felt.

One of the scientists in the team, Ryuji Hirayama says that the 'feeling' sense is extremely important to making the hologram real, saying "Even if not audible to us, ultrasound is still a mechanical wave and it carries energy through the air. Our system directs and focuses this energy, which can then stimulate your skin to feel content."

"The feeling of the tactile sensation is like a gently spraying your hand with pressurised air."

Jak's love for technology, and, more specifically, PC gaming, began at 10 years old. It was the day his dad showed him how to play Age of Empires on an old Compaq PC. Ever since that day, Jak fell in love with games and the progression of the technology industry in all its forms. Instead of typical FPS, Jak holds a very special spot in his heart for RTS games.
