Holographic screen

A holographic screen is a two-dimensional display technology that uses coated glass media for the projection surface of a video projector.

Additionally, the beam manipulation by the lenses can be used to make the image appear to be floating in front of or behind the glass, rather than directly on it.

This forms a virtual point of origin, so that the image source appears to be an imaginary object somewhere close to the glass.

When the user touches the screen, a tactile membrane film reacts to these movements, generating electrical impulses that are sent back to the computer.

Non-interactive holographic screens in shop windows can be coupled with artificial vision software to adapt ads based on the viewer's characteristics (age, sex, etc.).
