Computers are very visual devices Software companies aim to please the masses, not necessarily to help the minorities As touch devices become more and more prevalent, blind users are left behind Current assistance software cannot keep up with the progress of major corporations’ design 3 September 21, 2009 Joseph Conlin

Blind unemployment is on a decline * Unemployment still at 70% ** Workplaces rely on a person’s ability to quickly use computer systems Interactive systems are not designed for assistance software *Forbes: Blind people in the workplaceForbes: Blind people in the workplace **Bnet: America’s blind unemployment…Bnet: America’s blind unemployment… 4 September 21, 2009 Joseph Conlin

1.3 million blind adults in United States as of 2002 93,600 blind school age children Estimated 1.6 million blind adults by 2015 and 2.4 million by 2030 September 21, 2009 Joseph Conlin5 Data provided by: National Federation of the BlindNational Federation of the Blind

Vario Connect series ◦ Translates typed text and output into Braille ◦ Basically a Braille command line ◦ Does not fix the problem of interactive menus September 21, 2009 Joseph Conlin6 Images from: Baum Braille DisplaysBaum Braille Displays

Tactile Response ◦ Concept for a Braille display ◦ Only exists in drawings ◦ Does not recreate screen, only displays its own software ◦ Too small for large interactive applications ◦ Uses primitive technology September 21, 2009 Joseph Conlin8 Images and information from: Tactile ResponseTactile Response
9
Combination of the two technologies ◦ Use the small plastic dots from the Vario devices and place them into a larger grid using the concepts from the Tactile Response device. ◦ Three states of a dot Depressed Normal Raised ◦ Allow user to press down on any dot and have it register to the computer that an action was performed September 21, 2009 Joseph Conlin9
10
Hardware ◦ Device to raise and lower a grid of dots and sense when any of them are depressed ◦ Covered with a plastic sheet to protect dots and minimize wear and tear September 21, 2009 Joseph Conlin10
11
Find edges of on screen items, redisplay them as patterns of dots. Translate text into Braille for display on the screen September 21, 2009 Joseph Conlin11
12
Need for new hardware ◦ Proof of concept is simple enough to create ◦ Full sized device will be extremely difficult Braille translators are still very primitive ◦ Does not recognize special characters ◦ Total of 256 Braille characters in the 8 dot system ◦ Numbers and character cases are difficult to accurately display abc = abc ABC = abc 123 = 123 September 21, 2009 Joseph Conlin12

Computers are increasingly difficult for blind users to utilize Visual GUIs designed around a user’s ability to see are getting more and more complicated to the point that accessibility software can no longer keep up We need a device that will translate visuals into a physical form that blind people can feel and interact with the same way we do with a screen September 21, 2009 Joseph Conlin13
