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.

  • Example: perceptual disabilities, brain injury, minimal brain dysfunction, dyslexia, and developmental aphasia
  • 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.
  • Amazing Video Magnifiers - Specializing in Telesensory video magnifiers which enable people with low vision, including Macular Degeneration, to see to read and write. AmbuTech - Manufactures mobility canes for the visually impaired and the disabled community. Big Type Company, The - Large print date calendars, address books, check registers and bold ink 20/20 pens. BlindSoftware.com - Offers accessible freeware and shareware downloads for the visually impaired. C Tech - Distributor of low vision products and adaptive technology for the blind, visually impaired and learning disabled.

  • Assistive technology in Teaching students with vision problem Dr. Amjad Ali Arain Dr. Azhar Mehmood Mr. Sheikh Tarique Mahmood 3oth March 20121st international Conference on Metal Health
  • Learning DisabilitiesA disorder in one or more of the basic psychological processes involved inunderstanding or in using language or in performing different task.
  • Classification of disabilities Attention Deficit DisorderDevelopmental Disabilities Autism . Down syndrome Dyslexia Alzheimers Disease Anxiety Disorder DepressionMental Disabilities Dyscalculia Intellectual disability Phobia Sensory disabilityPhysical Disabilities Mobility Impairment
  • Impairment vs DisabilityImpairments: Loss of physiological orpsychological function due to an injury,illness, or congenital (inborn) condition.Disability: Loss or limitation of opportunitiesto take part in society on an equal level dueto social and environmental barriers.
  • Types of Sensory DisabilityVisual impairmentHearing impairmentOlfactory and gustatory impairmentSomatosensory impairment
  • Types of Visual ImpairmentPartially sighted Low visionBlind
  • Some possible effectsSlowdown the learning processDelay academic achievementReduce employment opportunitiesLimited participation in societyLow earningsDecrease the quality of life
  • How to reduce the effect of disability? I am successful because I use Assistive Technology
  • What is Assistive technology or Adaptive Technology (AT)?Devices designed or modified to helpindividuals in overcoming physical or cognitive difficulties, impairments, and disabilities
  • History of Assistive Technology.
  • Assistive Vs Educational TechnologyAT is more personal to the studentET is more classroom-based
  • Types of Assistive TechnologyAccess Controls/ environmentDaily Living AidsAssistive MobilityAssistive ListeningCommunication Aids Class roomVisual Aids
  • Assistive Visual Technology in Class room Old New Large print charts  Video projectors Special Markers  NiteWriter Pen Bold line notebook  Large Keyboards Books Tablet Watching glass  CCTV
