Virtual reality (VR) is a multidisciplinary area of research
aimed at interactive human–computer-mediated simulations of
artificial environments. An important aspect of VR-based systems
is the stimulation of the human senses – usually sight, sound,
and touch – in such a way that a user feels a sense of presence
in the virtual environment. Sometimes it is important to combine
real and virtual objects in the same real or virtual environment.
This approach is often referred to as augmented reality (AR),
when virtual objects are integrated into a real environment.
Typical VR applications include simulation, training,… more…
