VR pod

A Visiontron, also referred to as tranquility lounger and simulation pod, is a large device allowing the user to experience virtual reality simulations in a controlled environment.

Characteristics
An oval pod, the Visiontron contains a single chair inside, with two high-resolution displays equipped with coils situated immediately in front of the user's face. The back and base of the chair contain all the hardware necessary to process the user's input into the simulation. The actual simulation runs through a processing center the Visiontron is connected to, such as a Think Machine 3600r mainframe, which is used in Vault 112.

The programming used in the different models varies by the intended purpose of the simulation. For example, the civilian versions used in Vault 112 have their built-in security protocols enabled, which are supposed to prevent harm from coming to the user in effect of injury or death within the simulation, whereas the military version used to simulate the Battle of Anchorage had its safety protocols disabled, resulting in cardiac arrest for the occupant in case they die within the simulation.

Capital Wasteland
Twelve loungers are on the main floor of the Vault 112, nine of which are inhabited by its former occupants, one by James, one being broken, and one reserved for the Lone Wanderer. Another lounger, which is occupied by Dr. Stanislaus Braun, is located in his office.

The loungers measure their occupant's vital signs, and are equipped with stasis devices, allowing for user to be kept alive for prolongued periods of time. A Vault 112 jumpsuit is required to enter a lounger, which runs the Tranquility Lane simulation, a virtual reality designed by Dr. Braun.

A single, enclosed simulation pod is located in the Outcast outpost. It is running a recreation of the Battle of Anchorage, designed by Virtual Strategic Solutions, for the purposes of analyzing the operation and mining all possible data. These simulations were later substantially altered on orders from General Constantine Chase.

Mojave Wasteland
The Hidden Valley bunker has four Visiontron virtual reality pods on Level 2, which run combat simulations based on old VR tapes salvaged by Head Scribe Taggart. The were used by members of the Mojave Brotherhood of Steel to hone their skills in combat during the lockdown, without having to actually participate in it.

Nellis Air Force Base contains three intact Visiontrons, which were used for pilots to be trained in virtual simulations of air combat against the Chinese Air Force, particularly Xian-85 fighters.

Appearances
The Visiontron appears in Fallout 3, its Operation: Anchorage add-on, and Fallout: New Vegas.

Behind the scenes
According to pre-release concept art, the Tranquility Loungers in Vault 112 were hooked up to a Simtek 6000 supercomputer.
