Holo room

From ROI Wiki

A Holo Room is a specialized room located on an Earthfleet starship, base, colony or any other location owned or controlled by Earthfleet or the Brayburn Society created with the intention of providing either a simulated training or entertainment environment built around Solidic Holograms. Standard holo rooms (not to be confused with the "holodecks" of Star Trek) are approximately 10x10x10feet in size and can accommodate up to 4 people. For more than 4 people, larger rooms are available.
