Technology Focus series: How can volumetric displays help utilise more information?

Volumetric displays are 3D visual representations that can be viewed from angle and without glasses or headsets. They are still in the development stages but have the potential to add value to current display technologies.

Volumetric displays are a branch of the 3D display family. A visual representation of an entity is created by the emission, scattering, or relaying of illumination throughout a 3D space (Holographic displays only scatter light at a 2D surface), with the emitters being co-located with the real image points. Volumetric displays can be viewed without glasses or headsets. The user can view the display from any angle because the emitters are co-located with the real image points.
