REVIEW ON THE EFFECTIVE USE OF AUGMENTED REALITY TO PEOPLE WITH
SPECIAL SKILLS
International Scientific ConferenceeRA-62011

• 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.

• 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

• 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.

• 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.

• 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.

• 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
[Evaluating the Post-Stroke Patients Progress Using an Augmented Reality Rehabilitation System, Alamri et. al., 2009]
• 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.

• 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.

• 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.

• 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.
