EXPAND PRESENCE IN 
VIRTUAL REALITY SPACE
What is Virtual Reality? 
• Virtual Reality (VR) is the use of computer 
technology to create a simulated environment.
• Human beings are visual creatures, and display 
technology is often the single biggest difference 
between immersive Virtual Reality systems and 
traditional user interfaces.

Virtual Reality Technology
• Virtual Reality’s most immediately-
recognizable component is the head-
mounted display (HMD).
• While they are fun for people in universities 
and big labs, consumer and industrial 
wearables are the wild west.

Virtual Reality Glasses
• Virtual reality glasses or goggles are 
becoming increasingly popular in the 
gaming and entertainment spheres. 
• They are lighter and more comfortable to 
wear than the standard head mounted 
display (HMD) and many of them 
incorporate a range of interactive devices.

Types of Virtual Reality Glasses
• The types of VR glasses include:
– Virtual reality glasses for PC
– Virtual reality glasses for PS3
– Virtual reality glasses for Mac
• These glasses can be compared to a 
wearable computer monitor which along 
with an input device such as a data glove or 
joystick enables the wearer to experience a 
three dimension.

Head Tracking Systems
• More advanced versions of these glasses 
contain head tracking systems. 
• This system is connected to a computer 
which sends signals to adjust the images 
seen by the wearer as they move around 
their environment.

Architectural Purposes
• These glasses enable the wearer to see 
three dimensional images which give an 
illusion of depth of perception. 
• For example, if the wearer is using virtual 
reality for architectural purposes then they 
will be able to view a building at different 
angles, and walk through or around it.

Maps the Movements
• Many types of glasses contain a tracking 
system which maps the wearer’s 
movements and adjusts the images 
accordingly. 
• Each time the wearer moves his head, 
walks in a particular direction or takes 
some other form of action, the scene in 
front of him changes as he does so.

Illusion of 3D Depth
• The glasses enable the wearer to see two 
separate images which the brain combines 
into one. 
• This is what gives the illusion of 3D depth. 
This is often accompanied by video and/or 
sound which add to the experience..

Realistic View
• The aim is to present the wearer with a 
world which is realistic and behaves in a 
similar way to the real world. 
• Any delay or latency will cause a 
disconnection between the two and in 
some cases, feelings of motion sickness.

Medical Training
• Due to its interactive nature, medical and 
dental students have begun using VR to 
practice surgeries and procedures.
• It allow for a consequence free learning 
environment; the risk of inflicting harm or 
making a mistake while practicing on real 
patients is eliminated.
