Holography

Holography is an integral part of most user interfaces, particularly that of the onboard computer in an individual's dermis. Holograms are used to make interactive displays as well as protective shielding, and is essential to any piece of equipment designed to be collapsible, such as most conventional weaponry.

Holograms are created by manipulating muons into stable lattice structures to form forcefields, which are invisible to the naked eye. In personal and vehicle shielding, for instance, this is preferred, but for interactive purposes the muon structures are infused with photons, giving the hologram the impression of being made of light.

The use of holography makes physical displays obsolete. Instead, anything from computer interfaces to simple signs are projected by holoemitters, either overlaying a surface or free in mid-air.
