Visually Impaired
Visual impairment (or vision impairment) is vision loss (of a person) to such a degree as to qualify as an additional support need through a significant limitation of visual capability resulting from either disease, trauma, or congenital or degenerative conditions that cannot be corrected by conventional means, such as refractive correction or medication.
Assistive Technology available:
1. Magnifiers
Visually impaired individuals will often use magnifiers to assist with reading and viewing. This device allows for independent viewing of material that would otherwise be too small to see. Magnifiers are ideal for a wide range of individuals, from young students to the elderly. One challenge of using this device in a classroom is that it is bulky and students may not bring it to class as needed. It may also cause a problem outside of the home, such as at the grocery store, for the same reason.
2. Optelec ClearReader+ OCR Reading and Scanning Device
This user friendly device offers high quality, multilingual voice output and fast optical character recognition (OCR) and text-to-speech recognition technology for the visually impaired. The intuitive portable reading assistant captures any printed material such as letters, newspapers and books, and reads text aloud using a naturally sounding voice. This device costs 2245.00$! And this is in US funds.
3. JAWS for Windows
This popular screen reader works with your PC to provide access to today’s software applications and the Internet for those who are blind or have low vision. Its multilingual synthesizer, Eloquence, speaks through the computer’s sound card, reading out information from the screen. This program is quite expensive, at 700.00$!
Ariadne GPS App
Cost: $5.99
Description:
Like a Guide Dog, this high tech assistive technology app
supports individuals who are visually impaired by enhancing their ability to be
mobile. If you have VoiceOver activated on your device, you will be able to
know the street names and numbers that are around you by touching them. You can
also explore a different region than the one around you by telling the app the
street and the city. If you
add your favorite points to the app database, you can be alerted when you get
closer than a certain distance to one of them.
Targeted Population:

using VoiceOver and gives you access to information that are normally
