VISUAL IMPAIRMENTS  If you have a student who is blind or partially

sighted in your classroom some examples of assistive technology could include: Magnifying glass Software added to a computer enabling a student to

type and write Magnifying device that could help students read a book

or text in the classroom CCTV Braille device to read, write, and learn literacy sills Mobile device

In this session we will discuss some popular pieces of assistive technology for individuals who are blind or partially sighted. http://youtu.be/A2bsTOZ71Mw

BRAILLE

A way to write letters based on the 26 letters in the alphabet.

Braille is a system of characters made up of raised dots.

Other codes are used for subjects such as math, science, music, and computers.

Students learn to read Braille by moving both hands across the lines of Braille words from left to right.

BRAILLE

Created by Louis Braille It is the single most important invention for

people who are blind in history. http://youtu.be/sqQ3gdE7ks0

HIGH ASSISTIVE TECH FOR INDIVIDUALS WITH VISUAL IMPAIRMENTS INCLUDE

Screen readers Screen magnification Reading machines Video magnifiers Refreshable Braille displays Braille translation software Note taker recognition Mobile devices http://youtu.be/lLaUx7BJ4r0

Page 20: Assistive technology for students with visual impairments

SCREEN MAGNIFICATION A screen magnifier is a tool that can magnify

everything (text, photos, graphics, etc) on a computer or a mobile device screen.

When using a screen reader, it results in only part of the original screen image being visible to the individual.

Screen magnifiers can sometimes include extra features such as: Contrasting background and text colors Mouse pointers and cursors can be enhanced Some can even do basic screen reading functions

Page 21: Assistive technology for students with visual impairments

SCREEN MAGNIFICATION

Some common screen magnifiers for Windows computers include: ZoomText MAGic  Supernova Screen Magnifier

Page 22: Assistive technology for students with visual impairments

SCREEN MAGNIFICATION

o Also, most recent computer running Windows, Mac OS X or Linux have a screen magnifier built into them.

o I would now like you to go into your own computer and try to find the screen magnification function. (Try the control panel) o Access your screen magnification toolo If you do not have one ,do a Google search of a free tool to

download and try and give it a shoto Report on twitter about your experience

Page 23: Assistive technology for students with visual impairments

SCREEN READERS

A screen reader gives an individual user information from a computer or mobile device through a spoken digitized voice.

A screen reader can also offer a user more information than just reading text on a page such as: Whether text is underlined on a page Whether a page or link was checked Whether a box to checked or unchecked

SCREEN READERS

The most popular commercial screen readers include  JAWS Window-Eyes  Supernova Screen Reader.  NVDA Thunder  System Access to Go

READING MACHINES

A reading machine utilizes a camera or a scanner with Optical Character Recognition (OCR) software.

Basically it turns a printed document into electronic text.

This text can then be relayed to a screen to read in large print or read aloud by a screen reader.

Page 27: Assistive technology for students with visual impairments

READING MACHINES

A reading machine can be Standalone – it combines a camera and a

scanner, OCR software, monitor and/or screen reader as one device.

Computer-based - a camera or scanner and OCR software can be added to your computer, which will already have a monitor and screen magnifier or screen reader.

Page 28: Assistive technology for students with visual impairments

VIDEO MAGNIFIERS/ CCTV

A CCTV is an aid that uses magnification and it is made of a camera and a monitor.

The magnification level is much greater than for a hand magnifier

Can be standalone or portable!

REFRESHABLE BRAILLE DISPLAYS

A braille display is used with a screen reader to output screen information in a tactile form.

It consists of a number of cells which have eight pins which can be moved up and down to form braille characters.

Page 30: Assistive technology for students with visual impairments

BRAILLE TRANSLATION SOFTWARE

Braille translation software can be used to convert an electronic document such as one in Microsoft Word, into braille.

The result can then be printed by an embosser, which is a printer that uses pins to indent the dots onto paper.

Page 31: Assistive technology for students with visual impairments

NOTE TAKER RECOGNITION SOFTWARE

These have a QWERTY (standard type) or braille keyboard, but output speech rather than using a computer screen, and as a result are much smaller than mainstream laptops or netbooks.

A notetaker will have a calendar and contact database, and most have email and internet capability.

VOICE RECOGNITION SOFTWARE

Voice recognition provides an alternative way to control or input information to a computer or mobile phone.

You talk to the computer or phone and what you say is interpreted as commands or converted to electronic text. While it started out as an access technology, voice recognition is mainly now being marketed as something for everybody.

Voice recognition is becoming more widespread on mobile phones, and it will be interesting to see how this technology evolves.
