Head mounted displays are often favored because they totally immerse the user in the simulation, but they weigh several pounds and are usually expensive. The BOOM is another kind of VR environment.

The user can move in a full circle and can also bend down to view objects. Control buttons on the handlebars usually serve as an interface, or other interface devices can be used in conjunction with BOOM including earphones and data gloves.
