  15. 15. HIGH ASSISTIVE TECH FOR INDIVIDUALS WITHVISUAL 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
  16. 16. 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
  17. 17. SCREEN MAGNIFICATION Some common screen magnifiers for Windows computers include:  ZoomText  MAGic  Supernova Screen Magnifier
  18. 18. SCREEN MAGNIFICATIONo 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 tool o If you do not have one ,do a Google search of a free tool to download and try and give it a shot o Report on twitter about your experience
  19. 19. 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
  20. 20. SCREEN READERS The most popular commercial screen readers include  JAWS  Window-Eyes  Supernova Screen Reader.  NVDA  Thunder  System Access to Go
  21. 21. SCREEN READERSo Also, most recent computer running Windows, Mac OS X or Linux have a screen reader built into them.o I would now like you to go into your own computer and try to find the screen reader function.

  22. 22. 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.
  23. 23. 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.
  24. 24. 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!
  25. 25. 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.
  26. 26. 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.
  27. 27. 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. http://youtu.be/J5nviwgNUas
  28. 28. 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.
