Holograms

Holograms are volumetric data that can represent recorded footage, technical designs, or any content the sender chooses. Alongside voice, text, and video, they are one of the most common message formats sent through the galactic messenger network.

They are presented in two main ways: through wearables such as virtual headsets and heads-up displays, or through a Holo Projector, which allows glassless viewing.

A Holo Projector uses an array of color-coded lasers coupled to particle spitters that eject bright and dark holofluid particles. Lasers illuminate the bright particles as visible points of light in space, while the dark particles block ambient light to sharpen visibility. The process runs continuously, allowing interactive display.

Interaction produces a subtle tactile sensation, and objects placed above the projection surface will block the display above them. Resolutions vary; a small 10x10 cm display might carry around 100x100 diodes.

Holofluid consists of two particle types: bright particles that light up under laser illumination to form the outer silhouette of a projection, and dark particles that fill the interior and block stray light. Combined and continuously agitated by a projector, the two particles produce a legible volumetric image.
