Visual Simulations/Virtual Reality Systems

Visual simulation is the use of a graphics interface to interact in real time with a simulation running on one or more computer systems. A virtual reality environment, which can be used to support a visual simulation, creates a 3D full immersion experience with user interaction. The user can then interact with the features of this virtual environment, and these digitally created features can, in turn, be dynamically modified to meet the objectives of the simulation.

Not all simulations require a virtual reality environment. Many are set up using traditional computer video displays or projection systems.

A virtual reality system combines operating software with environmental data-such as CAD designs, digital video or computer generated images-to enable a user to interact in real time with this virtual environment through a series of input/output devices.

• Sight: head-mounted display or goggles
• Sound: speakers or headphones
• Touch: data gloves and haptic devices
• Smell: currently in development

The operating software for a virtual reality system must coordinate the interaction of these components and, through IO devices, provide realistic reactions and responses to the user's actions.. VRSim has developed its own software solution known as the EndeaVR Suite.

Virtual reality systems and visual simulations are used to solve a variety of problems in such diverse areas as product design, product life cycle management (PLM), manufacturing, training and the visualization of complex data. VR can also be used in the entertainment industry (games, gambling, and amusement attractions), retail (product demos, design testing), and sensory activities (relaxation, personal physical simulation).
