Students with visual learning disorder have to face the biggest challenge of “printed materials” inside and outside the school. The modern development in science has given birth to Assistive Technology that is helping in designing, developing and improving assistive, adaptive, and rehabilitative devices for people with disabilities and disorders. The use of Assistive Technology, in Learning-Related Vision Problems, can help such students to improve their performance and use their learning potential more efficiently.

2. Learning Disabilities
A disorder in one or more of the basic
psychological processes involved in
understanding or in using language or
in performing different task.
4. Impairment vs Disability
Impairments: Loss of physiological or
psychological function due to an injury,
illness, or congenital (inborn) condition.
Disability: Loss or limitation of opportunities
to take part in society on an equal level due
to social and environmental barriers.
5. Types of Sensory Disability
Visual impairment
Hearing impairment
Olfactory and gustatory impairment
Somatosensory impairment
6. Types of Visual Impairment
Partially sighted Low vision
Blind
7. Some possible effects
Slowdown the learning process
Delay academic achievement
Reduce employment opportunities
Limited participation in society
Low earnings
Decrease the quality of life
8. How to reduce the effect
of disability?
I am successful
because I use
Assistive
Technology
9. What is Assistive technology or
Adaptive Technology (AT)?
Devices designed or modified to help
individuals in overcoming physical or
cognitive difficulties, impairments,
and disabilities
11. Assistive Vs Educational
Technology
AT is more personal to the student
ET is more classroom-based
12. Types of Assistive Technology
Access Controls/ environment
Daily Living Aids
Assistive Mobility
Assistive Listening
Communication Aids Class room
Visual Aids
13. Assistive Visual Technology

Olfactory and gustatory impairment:Impairment of the sense of smell and tasteSomatosensory impairment:Insensitivity to stimuli such as touch, heat, cold, and pain
Partially sighted - a person can see but with some difficulty; Low vision - a more severe impairment of vision, person is unable to read at a normal viewing distanceat a normal viewing distance, even with the aid of eyeglasses or contact lenses; They use a combination of vision and other senses to learn. It can be Myopia (shortsightedness) or Hyperopia(longsightedness) Blind - a person having no useful sight."Totally blind" students learn via Braille or other non-visual media."Legally blind" indicates that a student has less than 20/200 visionColour Blindness Inability to perceive colours in a normal fashion.
Doctors and teachers often attribute the behavior to attention deficit disorders (Novak, 2009)
improve their lives and increase their independence and productivity.
Impairments: loss of physiological or psychological function due to an injury, illness, or congenital conditionDisability: loss or limitation of opportunities to take part in society on an equal level due to social and environmental barriers.
A fine difference and sometime no difference
Visual Aids:This includes large-print books, books on tape, magnifiers, talking computer software, and Braillers.
AT can help your child learn the classroom material in a way that they can understand it. It can also help reduce the barriers your child may face that may prevent them from being at the same level as their classmates. Some examples of AT include:
Computer-based instruction can support other learning activities. a student with poor visual skills may access information about a specific topic using text reading computer software.
