Virtual reality (VR) is a simulated experience that can be similar to or completely different from the real world. Applications of virtual reality can include entertainment and educational purposes. Other, distinct types of VR style technology include augmented reality and mixed reality.
A simulation is an approximate imitation of the operation of a process or system; that represents its operation over time.
SIMNET was a wide area network with vehicle simulators and displays for real-time distributed combat simulation: tanks, helicopters and airplanes in a virtual battlefield. SIMNET was developed for and used by the United States military. SIMNET development began in the mid-1980s, was fielded starting in 1987, and was used for training until successor programs came online well into the 1990s.
Virtual Heroes, Inc. is a developer of serious games in Raleigh, North Carolina, United States. It was founded in 2004.
Virtual reality in telerehabilitation is a method used first in the training of musculoskeletal patients using asynchronous patient data uploading, and an internet video link. Subsequently, therapists using virtual reality-based telerehabilitation prescribe exercise routines via the web which are then accessed and executed by patients through a web browser. Therapists then monitor the patient's progress via the web and modify the therapy asynchronously without real-time interaction or training.
Immersion into virtual reality (VR) is a perception of being physically present in a non-physical world. The perception is created by surrounding the user of the VR system in images, sound or other stimuli that provide an engrossing total environment.
The United States Army CCDC Ground Vehicle Systems Center (GVSC), located in Warren, Michigan, is the United States Armed Forces' research and development facility for advanced technology in ground systems. It is part of the U.S. Army Combat Capabilities Development Command (CCDC), a major subordinate command of the U.S. Army Futures Command. GVSC shares its facilities with the U.S. Army TACOM Life Cycle Management Command. Current technology focus areas include Ground Vehicle Power and Mobility (GVPM), Ground System Survivability and Force Protection, among others.
A robotics simulator is a simulator used to create application for a physical robot without depending on the actual machine, thus saving cost and time. In some case, these applications can be transferred onto the physical robot without modifications.

The Deployable Virtual Training Environment (DVTE) is a laptop based platform for a wide variety of training simulations in the USMC. TRASYS web. DVTE consists of two main components, the Combined Arms Network (CAN) and the Infantry Tool Kit (ITK). A typical DVTE suite consists of 32 laptops and a modified NVisor SX Head-mounted display (HMD).
The Infantry Immersion Trainer (IIT) is a mixed reality training facility prototype for small unit Infantry located in a 32,000-square-foot (3,000 m2) former tomato packing plant in Marine Corps Base Camp Pendleton, California. It has been in operation since November 2007. The original IIT is now known as IIT Phase I. A purpose built IIT was built adjacent to Phase I in Camp Pendleton. A second IIT was built in a historic warehouse in Camp Lejeune, NC and a third was built in MCB Hawaii.
An instructional simulation, also called an educational simulation, is a simulation of some type of reality but which also includes instructional elements that help a learner explore, navigate or obtain more information about that system or environment that cannot generally be acquired from mere experimentation. Instructional simulations are typically goal oriented and focus learners on specific facts, concepts, or applications of the system or environment. Today, most universities make lifelong learning possible by offering a virtual learning environment (VLE). Not only can users access learning at different times in their lives, but they can also immerse themselves in learning without physically moving to a learning facility, or interact face to face with an instructor in real time. Such VLEs vary widely in interactivity and scope. For example, there are virtual classes, virtual labs, virtual programs, virtual library, virtual training, etc. Researchers have classified VLE in 4 types:
SimCraft, a privately held company headquartered just outside Atlanta, Georgia, is the creator of a proprietary motion simulation technology and manufactures simulation equipment integrating this technology, including professional driver in the loop racing simulators. The motion simulator technology, in development since 1998, is designed to recreate the manner in which vehicles move in earth physics. The company offers a range of simulator products in the category of motion simulation that provide a tactile true motion experience for Motorsport Simulation and flight simulation. The company's core innovation and technology is the simulation of vehicle movement through proprietary physics based software interfaces and a patent pending hardware architecture based on Center of Mass principles of motion. The company's product applications range principally by variation in chassis design and material and are found in usage from military training/research, professional training, to individual simulation and gaming enthusiast entertainment.
Military Open Simulator Enterprise Strategy (MOSES) is a U.S. Army project evaluating the ability of OpenSimulator to provide independent and secured access to a virtual world.
A surgery simulator is computer technology developed to simulate surgical procedures for the purpose of training medical professionals, without the need of a patient, cadaver or animal. The concept goes back to the 1980s with video games, but only in the 1990s with three-dimensional graphics and the 2000s with the use of motion sensors for realistic movements has the technology been able to simulate the real situation. The most common type of surgery taught through this method is laparoscopic surgery, although it has also been used to do a trial run before other kinds of procedures.
Pointman is a seated user interface for controlling one's avatar in a 3D virtual environment. It combines head tracking, a gamepad, and sliding foot pedals to provide positional control over many aspects of the avatar's posture. Pointman was developed by the US Naval Research Laboratory (NRL) to support the use of dismounted infantry simulation for USMC training and mission rehearsal. NRL's goal in developing Pointman was to extend the range and precision of actions supported by virtual simulators, to better represent what infantrymen can do.
Virtual reality sickness occurs when exposure to a virtual environment causes symptoms that are similar to motion sickness symptoms. The most common symptoms are general discomfort, headache, stomach awareness, nausea, vomiting, pallor, sweating, fatigue, drowsiness, disorientation, and apathy. Other symptoms include postural instability and retching. Virtual reality sickness is different from motion sickness in that it can be caused by the visually-induced perception of self-motion; real self-motion is not needed. It is also different from simulator sickness; non-virtual reality simulator sickness tends to be characterized by oculomotor disturbances, whereas virtual reality sickness tends to be characterized by disorientation.
Virtual reality applications are applications that make use of virtual reality (VR). VR is an immersive sensory experience that digitally simulates a remote environment. Applications have been developed in a variety of domains, such as education, architectural and urban design, digital marketing and activism, engineering and robotics, entertainment, fine arts, healthcare and clinical therapies, heritage and archaeology, occupational safety, social science and psychology.
Gazebo is an open-source 3D robotics simulator. Gazebo was a component in the Player Project from 2004 through 2011. Gazebo integrated the ODE physics engine, OpenGL rendering, and support code for sensor simulation and actuator control. In 2011, Gazebo became an independent project supported by Willow Garage. In 2012, Open Source Robotics Foundation (OSRF) became the steward of the Gazebo project. OSRF changed its name to Open Robotics in 2018.
