6. 1950’s visionary cinematographer Morton Heilig built
a single user console called Sensorama. This enabled
the user watch television in three dimensional ways.
In 1961,Philco Corporation engineers developed the
first HMD known as the headsight.
HISTORY OF VIRTUAL REALITY

7. In 1988,commercial development of VR began.
In 1991,first commercial entertainment VR system “Virtuality” was released.
It was in 1965 IVAN SUTHERLAND envisioned what he called the “Ultimate
display”.

8. TYPES OF VIRTUAL REALITY
VR Systems can be divided into three groups.
Non immersive systems (like workstations) see information about the real
world,presented via-computer location based services,GIS.
Augumented reality systems(like HMD)
stay in real world,but see simulated objects.
Immersive systems(like CAVE) see simulated world and “be” in that simulated
world.

9. AUGUMENTED REALITY
“STAY IN REAL WORLD,BUT SEE SIMULATED OBJECTS”
 Augumented Reality can be used for
training as well as for assembly purpose.

10. HARDWARE USED IN VR
The Logitech 3D mouse Figure is based on a ultrasonic position reference
array,which is a tripod consisting of three ultrasonic speakers set in a
triangular position,emits ultrasonic sound signals from each of the three
transmitters. These are used to track the receiver position,orientation and
movement.It provides proportional output in all 6 degrees of freedom:X,Y,Z,
Pitch,Yaw,and Roll.

11. MOTION TRACKERS
The Motion tracking system is based on magnetic sensors which
are attached to the user. Most common are sensors measuring the
intensity of a magnetic field generated at a reference point.The
motion of the different segments is tracked using magnetic
sensors. These sensors return raw Data(e.g positions and
orientation) expressed in a single frame system

12. VIRTUAL REALITY APPLICATIONS
ENGINEERING AND DESIGNING:
 VR is widely used in engineering and designing process
 It gives better understanding of the design and facilities changws wherever
necessary
 It helps to reduce the time and cost factor.
 Examples: Building construction,car designing

13. VIRTUAL REALITY IN MEDICAL FIELD
• Healthcare is one of the biggest adopters of virtual reality which encompasses surgery simulation,phobia
treatment,robotic surgery and skills training.
• VR finds it’s application in nursing,dentistry,health issues for the disabled.
