REVIEW ON THE EFFECTIVE USE OF
AUGMENTED REALITY TO PEOPLE WITH
SPECIAL SKILLS

• We have live view of real world environment, in
which details are augmented by a PC using sensor
inputs. Not visual recreation of an environment that is
not real, as Virtual Reality does.
• Augmented Reality supplements real world in stead
of completely re-creating it like Virtual Reality does.

Ronald T. Azuma, 1997]

• Augmented Reality is when a PC is used
as tool to make a task easier for a
human to perform. Visual objects include
more information than a human can
detect with his senses.
• Physiotherapists and doctors agree that
Augmented Reality helps patients’
rehabilitation.Fig.: http://www.extratech.gr

Disabled Children: A Preliminary Study, Richard et. al., 2007]

• A non-immersive recreational and educational augmented
reality application, dedicated in aiding disabled pupils by
allowing them to handle virtual objects in a simple and
intuitive way.
• Four virtual fruits are placed randomly on the left page of the
book. Pupils are asked to place the identical virtual fruits into
the same position on the right page.

Children: A Preliminary Study, Richard et. al., 2007]

• After finishing pairing, the program uses virtual cues ( blue
and red circles) to help the kid recognise any mistakes that
might have done.
• There are also auditory cues in order to give more help to the
kids.

7
• For the application’s development, Microsoft Visual C++ 6.0
and OpenGL Library were used.
• A webcam was used for pattern
recognition.
• 3D models built with 3DStudioMax.

8
• The research team end up with the conclusion that the
application has many pedagogical purposes.
• It is easy for teachers or parents to implement it at school or
at home, respectively.
• The application’s difficulty level can be adjusted to meet the
demands from a wide range of ages.

• A research team used
Augmented Reality to cope
with a 25-year-old woman’s
cockroach phobia. Virtual
cockroaches were displayed
on the woman’s hands. After
some sessions, her phobia for
cockroaches has been
eliminated.

• A camera attached at woman’s
head-mounted display (HMD)
enabled her to see the real
world around her.
• A relatively old fashioned
computer added the virtual
cockroaches that were
designed using 3DStudio and
exported in VRML format to the
environment.

• Post-stroke therapy carried out in an enhanced
environment, leads to faster rehabilitation.
• The fact that Augmented Reality system automates some
therapy procedures, allows therapist to supervise more
patients simultaneously.
• The patient can see his hand moving into a virtual
environment, through a Head Mounted Display (HMD).
[Evaluating the Post-Stroke Patients
Progress Using an Augmented Reality
Rehabilitation System,
Alamri et. al., 2009]

The necessary equipment
is the following:
 A webcam
 A head mounted
display (HMD)
 A data glove
 The decision support
engine
o The webcam captures the
real environment.
o The head mounted display
renders the processed
scene back to the patient.

• The first exercise asks the
patient to move a mug
numerous times, back and
forth a shelf.
• The patient must follow the
path provided by the PC.
• The PC program fills
randomly the shelf with
virtual objects.
13

• In the second exercise, the
patient has to move a real
object into 3 dimensions,
following a predefined plot.
• The exercise reviews the
patient’s ability to keep the
hand as steady as possible.
14

• Using ultrasonic sensors
to generate a 3-D baby’s
model.
• Ability to examine the
fetus and plan a
Caesarean in advance
with high accuracy and
completely harmless.

• Using Augmented Reality
to help guide the needle
during a breast tumor
biopsy.
• More accurate results
• Less error chances

• Augmented reality can be used to
forestall traffic accidents. Road-
line highlighting and closing car
notification are only some
examples.
• For many years Augmented
Reality is used at football courts to
help referees with their decisions.

• People with special skills can be extremely assisted in their everyday life
while Augmented Reality is able to ease their pain.
• New elements and devices enable and improve clinical utility of
evidence-based treatments.
• Mobile devices interventions can assist with management of chronic
diseases.
• Augmented Reality can be used for improving physical activity &
kinesiology.

Augmented Reality Rehabilitation System, Alamri et. al., 2009]

19
• Mental reaction in front of virtual entities of disabled children.
• Improving children decision making through 2D & 3D plant entities.
• Autistic & trisomic children could express positive emotions.
• New teaching methods can be developed with emphasis on
disabled children using more playful ways.

20
• Children treatment for emotional problems using cognitive
behavior therapy principles & augmented reality.
• Augmented Reality is a really promising scientific field that
involves numerous specialties.
• Further Research & Development in Augmented Reality is
imperative.
