4. Devices to Assist Students
with Hearing Impairments
Hearing Aids
Infrared Systems
Audio Loops

5. Hearing Aids
 a miniature public address system worn by
the user (listener)
 works best in quiet, structured settings,
where the speaker is no more than a few
feet away and extraneous noise is
minimized

6. Infared Systems
transmit clean, clear sound
invisibly to hearing impaired
listeners
provide better hearing in public
places without the hassle of wires
and cords

7. Audio Loops
 a type of amplification system that was
introduced to meet the need to:
 control the sound level of the teacher’s voice
 maintain consistency in auditory cues between
home and school
 deal more effectively with background noise
 provide maximum mobility within a classroom.

8. Alternative Input Devices for
Students
with Physical Disabilities
Basic Adaptive Keyboards
Touch-Sensitive Screens
Voice Recognition

9. Basic Adaptive Keyboards
 These keyboards are excellent for individuals
with a limited range of motion or for individuals
who have a difficult time applying pressure to
keys.
 Standard keys were replaced with a larger keys
that are easier to see and touch

10. Touch-Sensitive Screens
 allows the user to simply touch the
computer screen to perform a
function
 There are software that enables
the users to create their own
overlays

11. Voice Recognition
• Voice recognition systems allow
students to operate a variety of
application programs, to dictate to a
word processor, and to enter data into
spreadsheets.
• the user can bypass the keyboard and
just speak to the computer

12. Devices to Assist Students with
Visual Impairments
Computer Screen Magnification
Closed-Circuit Television
Magnification (CCTV)
Braille Notetakers

13. Computer Screen
Magnification
 allow for the magnification of the
screen through the use of
special software
 the user can select a portion of
the screen and then enlarge that
section up to 16 times the
original size

14. Closed-Circuit Television
Magnification (CCTV)
is designed to enlarge any type of
text or graphic material by using a
small vertically mountedvideo
camera with a zoom lens directly
connected to a monitor for
displaying the image

15. Braille Note-takers
are small, portable devices that
enable students to enter and store
Braille characters in the form of
words and sentences.
most note takers allow users to
review what they have written by
listening to the text-to speech
function of the device
