2. What is meant by specially abled?...
This phrase is used because it supposedly humanizes disabled people by
focusing on their abilities rather than on their impairments.

Archery

3. Specially Abled Persons

4. Category of Disabilities
• Mobility
• Cognitive
• Visual
• Hearing

5. Assistive Technology
Any product, instrument, equipment specially
designed or adapted for improving the
functioning of a person.

6. What are the needs for assistive
technology?
According to WHO 2004 report, about
0.5% of a world population need prosthetic or
orthotic devices, about 1% need a wheelchair,
and about 3% need a hearing aid [1,2].

7. Technologies for enhancing their abilities
• Prosthetic limbs
• Assistive devices for Visually impaired
• Assistive devices for Cognitive aids
• Assistive devices for Mentally Retarded
• Hearing Aids

8. Prosthetic Limbs
Cosmetic
• Cosmetic prostheses do not improve function but are used to improve a person's
appearance after the loss of a body part.
• Prosthetic implants are also available to correct facial deformities from disease
or trauma.
• Like hands, fingers, feet and toes.

9. Prosthetic Limbs (Cont’d)
• Mechanical Limb
Cable operated limbs work by attaching a harness and cable around the opposite
shoulder of the damaged arm.

10. Prosthetic Limbs (Cont’d)
• Orthotic devices
Externally applied device used to modify the
structural and functional characteristics of the
neuromuscular and skeletal system
• EMG based
Use surface electrodes for picking up the
muscle activities for moving the artificially
connected limbs.

11. Prosthetic Limbs (Cont’d)
• Bionic limbs
biology and electronics
Use electrodes to sense muscular impulses in the
residual limb; electronic control systems detect
those signals and amplify them to power electric
motors that operate the prosthetic limb as though it
were real. In other words, the patient thinks "I want
to move my arm," their brain stimulates muscles in
the residual arm, the electronic system commands
the electric motors to move and the prosthetic limb
shifts accordingly [3].

12. Standing Frame
• Active standing provides lower body range of
motion and upper body strengthening
• Standing Frame is used throughout spinal cord,
stoke, cerebral palsy, multiple sclerosis and
other neurological rehabilitation.

13. Clubfoot Brace
• Children's who loose ligaments between
ankle and foot. It necessary to reduce the
60 degrees to 40-50 degrees.
• The space between the heels of the shoes should be the same.
• Clubfoot Brace sometimes called an AFO (Ankle Foot Orthosis)

14. Other Assistive Devices
Wheelchairs
• Wheeled mobility device on which the
person sits
• Manual and Powered Wheelchairs
Walkers
• Walking frame for disabled and elderly people
who need additional support to maintain balance
and stability

15. Cont’d
Scooters
• Scooter mobility aid is equivalent to a wheelchairs
but configured like a motor scooter.
Canes and Crutches
• Reduce stress on the affected limbs
• And persons become more mobile
• Adult walker, rollators, canes, crutches

16. Cont’d
Feeding Robot
• A dining robot that gives the power to people with special abilities to
control their meals.
• Robot arm that can scoop food from a bowl and deliver the food to the
mouth.

17. Assistive Devices For Visually Impaired
Braille And Braille Embossers
• Braille is a system of raised dots formed into units
called braille cells [4]
• Braille embosser imprints the raised dots of braille onto
a page
• Duxbury, Megadots and braille 2000 are the braille
translation software
Large-print And Tactile Keyboards
• The "bump dots" on the keys help the user to
find right keys in a tactile way.

18. Rattle Soccer Ball
• Instead of having a few bells inside the ball,
dozens of "rattlers" carefully installed between
the layers of the ball near the outside makes
sound even with the slightest movement [5].
White Cane
• White cane are used for peoples who are blind or visually impaired.
Its primary uses are as a mobility tool and as a courtesy to others.
• Long cane, Guide cane, support cane, fold cane,
Kiddie cane are the type of White cane
Cont’d

19. Cont’d
Hoople
• LASER
• Ultrasonic [6]

20. Cont’d
GPS navigation
In addition to obstacle avoidance, the ideal navigational aid also must address
two other key aspects of independent travel: orientation (the ability to monitor
one’s position in relationship to the environment) and route guidance (the
ability to determine a safe and appropriate route for reaching one’s destination)
[6].

21. Cont’d
Tactile Paving
• It is a surface pattern of truncated domes, cones or
bars detectable by long cane or underfoot which are
used to alert the visually impaired of approaching
streets and hazardous surface or grade changes [7].
Smart Glasses
• It consist of video camera that mounted on the top and control unit which is small
enough to fit in a pocket and software that provides
images of objects close-by to the see-through
displays in the eyepieces of the glasses [8-9].

22. Desktop Video Magnifier
Electronic devices that use a camera and a display
perform digital magnification of printed materials
Screen magnification software
Software that interfaces with a computer
graphical unit to present enlarged screen content.
Cont’d

23. Assistive devices for Cognitive Aids
Electronic Math Work Sheets
• Software programs that can help students
through math problems.
• Helpful for who have trouble aligning math
problems with pencil and paper.
Speech Recognition Programs
• Writing technology strategies that includes
pencils to computer input by voice.

24. Cont’d
Talking spell checkers and electronic dictionaries
• Aid to support poor speller select or
identify appropriate words
Variable-speed tape recorders
• Pre-recorded text or to capture spoken
information and play it back later

25. Cont’d
Abbreviation Expanders
• Software allows to create, store, and re-use abbreviations for frequently-used
words.
• Beneficial for people who struggle with
writing skills.
Word Prediction Programs
• Software helps a user during word processing
by “predicting” a word that the user intends to
type.
• Helpful for proper spelling, grammar, and
word choices, with fewer keystrokes.

26. Cont’d
REMINDER WATCH
• This device might help in structuring everyday life.
• Reminder watch reminds to get dress up, having breakfast,
request to going bed
TIME LOG
• Visual count down timer
• Timer for lunch is coming, or to a couple of hours for
a special assignment

27. Cont’d
HANDY ASSISTIVE PLANNING TOOL
• Control over one tasks
• Planning tool that can program for selective activities
• It will notify the signal of expiration of time or
delineate periods of time for his tasks.

28. Assistive Devices For Hearing Impaired
Body Worn Hearing Device
• Wires from a body worn unit are connected to molded ear pieces.
• used for poor dexterity and require a high powered aid.
BTE Hearing Aids With Ear Molds
• Microphone part that fits behind the ear and an
ear piece fits inside the ear.

29. Cont’d
Canal Hearing Aid
• Small enough to fit almost entirely in ear canal
Ear Hearing Aid
• Microphone and all other parts of the hearing aid contained
within a molded ear piece which sits inside the ear canal.

30. Cont’d
Audio Induction Loop (also Hearing Loop)
• It is a special type of sound system use by people with hearing aids, provides
a magnetic, wireless signal.
• In the public announcement system users set a tele-coil (T) switch to hear
announcements directly through their hearing aid receiver.
