Technology advances at such a rapid pace that new innovations are emerging every day capable of creating a parallel reality. The latter goes through holograms with which you can interact. As you read it, they create the first holograms you can touch and feel.
A research group based on flexible electronics and detection technologies at the University of Glasgow has developed a holograms They use what is known as “aerohaptics.” With them they create real sensations in people’s hands, fingers and wrists when they touch jets of air.
The “aerohaptic” system has also made it possible to create a projection interactive of a basketball that the user can touch, roll and also make it bounce in an almost real way. All this is thanks to the air jets that provide a tactile feedback system. These jets are modulated as a function of the virtual surface of the ball.
Touching a virtual object without gloves provides the user with an almost real and natural interaction. An illusion technique of a virtual 3D image is used for the object. Glass and mirror systems simulate a two-dimensional image that appears to float in midair.
These first holograms that can be touched and felt were presented on the television show Star Trek: The Next Generation where an immersive 3D holographic projection was shown that could be palpated and that produced the sensation of controlling and feeling the object.
This research goes a step further in what refers to virtual reality and its advances. Technological development in this field could, for example, develop the avatar of a person who is on the other side of the planet and give a handshake. Researchers also talk that it could be the first step in creating something like a holodeck.
In addition, the development of this technology will also allow adding other functions such as making users feel cold or hot surfaces by modifying the temperature of the air flow. Investigations are also advancing in add aromas to this airflow thus making virtual objects can be smelled by users as they touch them.
Holograms have their origin in the middle of the 20th century and in the 21st century they are used in medical systems, in art, education and also in security and defense.
