Holograms

Holograms are a different technology than avatars. They are usually a three-dimensional (3D) recording of a real object, but they can also be computer generated. Holograms are primarily used in hybrid settings or in Augmented Reality (AR) settings, for augmenting with computerised 3D images of the physical world. They can be used in places such as museums, concert halls or meetings.

There are various ways of creating holograms, but to display them you need one or more holographic displays. These, could be augmented-reality glasses or a display that sits on the table or is wall-mounted and the image raises from it.

To capture or construct a 3D image, you can use your own mobile phone if it is equipped with a LiDAR camera. A LiDAR camera uses laser or infrared light to create a 3D representation of the surrounding environment. To create and display 3D holographic content you can view and interact with, you will need to capture a high quality mobile volumetric video. You will require a multi-sensor capture setup with several cameras shooting the object from different angles at the same time. A computer program that uses Artificial Intelligence (AI) will then put the images together and display or project them using the holographic displays into an object that seems to be floating in the air.
