Holograms have been created that can be touched

The TV series Star Trek: The Next Generation introduced millions of people to the idea of a holodeck: a realistic three-dimensional holographic projection of a complete environment where you can interact with your environment and touch objects. Now scientists have invented a system that makes this idea a reality.

Holograms are increasingly being used in our daily lives: they are used in medical systems, education, art, security and defense. But so far, visual images remain only visual. A team of flexible electronics and sensing researchers at the University of Glasgow has developed a hologram system using "aerohaptics," which creates a sense of touch using jets of air. These jets of air create a sense of touch on people's fingers, hands and wrists.

Technology can allow us to shake the hand of a colleague who is on the other side of the world and with whom we are communicating virtually - to feel the touch and to shake hands. And what prospects are opening up for sites like OnlyFans or PornHub, one can only guess. The main thing is not to catch cold in the air currents.

In some ways, this is a step up from the current generation of virtual reality, which requires you to wear a headset, glasses, and smart gloves or handheld controllers to provide haptic feedback. Adding a sense of touch can give holograms an extra dimension without having to wear gloves to feel contact with objects.
