

Expert System give the
computer the ability to
make suggestions and act
like an expert in particular
field.
Expert systems have been
used to monitor complex
systems
like
nuclear
reactors, perform medical
diagnoses, and develop
marketing plans for a new
product or new investment
strategies.

16. Virtual Reality Systems
 Immersive
virtual reality, which means the

17. Virtual Reality
A Head-Mounted Display
The
head-mounted
display (HMD) was
the first device of its
kind, providing the
wearer
with
an
immersive experience.

18. Virtual Reality
A Data Glove
Realistic interactions
with virtual objects via
such devices as a
data glove that senses
hand position allow for
manipulation,
operation, and control
of virtual world.
