Conclusion
What is VR
• Virtual Reality: A computer
system used to create an artificial
world in which the user has the
impression of being in that world
and with the ability to navigate
through the world and manipulate
objects in the world.“
What is VR
• "Virtual Reality allows you to
explore a computer generated
world by actually being in it"
What is VR
• Technology requirements
– Hardware capable of rendering
real-time 3D graphics and highquality stereo sound.
• Example: Head Mounted Display
HMD
What is VR
• Technology requirements
– Input devices to sense user interaction and
motion.
– Output devices to replace user's sensory
input from the physical world with computergenerated input.
SpiderWorld
Originally designed to treat phobic
patients over come their fear of
spider.
Performance Criteria
and Results
• Results
– One of the best ways to alleviate pain is to
introduce a distraction. Because virtual
reality immerses users in a threedimensional computer-generated world, it
is uniquely suited to distracting patients
from their pain.
– Burn patients undergoing wound care
report that their pain drops dramatically
when they engage in virtual-reality
programs Functional magnetic resonance
imaging shows that virtual reality actually
reduces the amount of pain-related activity
in the brain.
Performance Criteria
and Results
• Results
– Virtual-reality programs can also
help phobic patients overcome their
fear of spiders, heights, flying or
public speaking. A specially
designed program is now being used
to treat post-traumatic stress
disorder in survivors of the
September 11 attacks.

In 2000 Peretz B, Bimstein E evaluates the effects of imagery
suggestions during administration of local anesthetic in
pediatric dental patients.
In 2007 Susan M. Schneider and Linda E. Hood explore virtual
reality (VR) as a distraction intervention to relieve pain in
adults taking chemotherapy treatments for breast, colon, and
lung cancer.
In 2003 Susan M. Schneider et al explore the use of virtual
reality as a distraction intervention to relieve pain in women
receiving chemotherapy for breast cancer.
In 2004 Susan M. Schneider et al explored the effects of a
virtual reality distraction intervention on chemotherapy related
symptom distress levels in 16 women aged 50 and older.
In 1998 Hiroshi Oyama described several VR researches for
palliative medicine at the National Cancer Center Hospital
Japan.
Possible Risks
• Motion sickness
• People who suffer from
panic attacks, those with
serious medical problems
such as heart disease or
epilepsy, are subjects for
psychological risks.
– Excluding those having
such a situation is a typical
solution.
Future Work
• New VR hardware and software will be
designed by The Human Interface
Technology Lab (HITLab)
– VR hardware predicted to further enhance
the effectiveness of VR.
– a miniature projector
– VR software will be designed to be
effective for a longer time, and is designed
to be used day after day by the same
patient.
Conclusion
• As a robust distraction technique,VR could be
used effectively as a complementary therapy
to alleviate patient’s pain.
• VR can ease pain, both physical and
psychological.
• It can create therapeutic environments for the
evaluating and treatment of medical
conditions and to support exposure of anxiety
disorders.
• The treatment makes the patient into a virtual
environment that contains the feared situation
rather than making the patient into the actual
environment
