Out of the Box Technology

Smart phones and tablets are helping people with vision loss do many things that in the past had to be done with more costly, stand-alone assistive devices.

iPhone® and iPad®

The iPhone and iPad are currently the best devices available for people with reduced vision or who are blind. This is because both devices have built in accessibility options including VoiceOver, a screen reader that lets a person know auditorally what is happening on their multi-touch screen and helps the person navigate the screen even if they have no vision. Additionally, the IPhone and IPad have Siri for voice commands.

VoiceOver and a number of other accessibility options on the IPhone and IPad can be activated by going to Settings, next General followed by Accessibility. In Accessibility, you will find a variety of vision enhancing as well as speech options.

With VoiceOver on the IPhone and IPad, you can run your finger over the screen and the phone will name the app you are touching.

US Currency Reader

The Bureau of Engraving and Printing (BEP), in partnership with the Library of Congress' National Library Services for the Blind and Physically Handicapped (NLS), launched the free U.S. Currency Reader Program in 2015 as a means for blind or visually impaired individuals to denominate U.S. currency.

The currency reader, called iBill®, is a small hand-held device that denominates all U.S. currency in circulation in one of three modes: a clear natural voice, a pattern of tones, or a pattern of vibrations for privacy. The vibration mode also assists people who are deaf and blind in identifying a note’s denomination. The device uses a single AAA battery, which is included.

iBill

Currency reader applications are processed, and readers are shipped by the National Library Service – Library of Congress, which also administers a free library program of braille and audio materials for U.S. residents and citizens living abroad.

To request a free currency reader, individuals should complete the application located on Bureau of Engraving and Printing's (BEP) website at www.bep.gov/uscurrencyreaderform.html or call (844) 815-9388, toll free to request an application be mailed.


Music

Music Zoom ($19.95) is an iPad app specifically designed for musicians who are visually impaired. It allows the musician to view their music with as much magnification as they need. And, using a wireless foot switch, they can advance through their music while keeping both hands on their instrument.

Simple menus with large fonts and high contrast controls allow the musician to customize the appearance of their music to best suit their needs. They can adjust the magnification to make the music as big as they want/need it. If white on black contrast is easier to see, tapping the “invert colors” button will switch to reversed contrast. The scrolling speed of the music and working distance can be matched to each musicians’ preferences and the demands of the piece.

A wide variety of IPad mounts exist, allowing the musician to attach their IPad to a standard microphone boom stand if desired. This will enable the musician to position their IPad at a comfortable viewing distance, while not obstructing their instrument.
