17 Reading printed documents with
KNFB Reader
The KNFB Reader app enables you to read a wide variety of printed documents within seconds after
taking a picture. This is a great way to read printed memos, books, magazines, most restaurant menus,
and virtually any other kind of document typically printed from a personal computer.
Note that character recognition accuracy depends on many things, such as lighting, text quality, text
script, etc. Best results will occur with good lighting and standard black and white print outs.
WARNING: The KNFB Reader app is an app which has been optimized for use on your BrailleNote Touch,
however it is also an app which is offered at a cost on the Google Play Store. Any updates to the
BrailleNote Touch version of KNFB reader will be distributed from HumanWare in partnership with KNFB
technologies. These updates may arrive at varying times to the Google Play Store version of the app. In
addition, the full KNFB user guide found in the KNFB app is generalized for use on any device. It is for
example not advised to place your BrailleNote Touch upon a stand, which was not customized for such
use. This option is available for some smartphones which stands have been manufactured for this
scanning purpose.
17.1 Launching KNFB Reader
To launch KNFB Reader, from the main menu, press K or navigate to KNFB Reader and press ENTER or
one of the cursor routing buttons.
17.2 Taking a picture, reading, and
saving documents
When KNFB Reader is launched, you will be in the Image Capture screen. With the screen facing up,
place your BrailleNote Touch down with the camera in the center of the document with your Touch in
the same orientation as the document. Then, lift your Touch straight up to an appropriate distance;
about 3 to 5 inches away from the document.
To take a picture, with your focus on the “Take Picture” button, simply press a cursor routing button.
Alternatively you can press the Touch’s Action button, located on the right side of the device. You will
hear a camera shutter sound. For best results, avoid moving the BrailleNote Touch while the picture is
taken.
When the text is recognized, it should appear in Braille on the display. Navigate with your left and right
thumb keys or press SPACE with DOT 1 or dot 4 to move line by line through the recognized content.
You can save the document by navigating to and activating the Save Document button, or use first letter
navigation by pressing S.
