15.5.2 Importing Graphs
Teachers can import graphs to the BrailleNote Touch to give their blind students an idea of their spatial
aspect. One way this can be done is by first finding an image of the graphic on Google Images, saving it,
and opening it with Windows Paint. Then, they can save the image as monochrome bitmap (.BMP) using
the Save As function of Windows Paint and transfer this file on the BrailleNote Touch to be read.
15.5.3 Exporting Graphs
It is possible to export KeyMath graphs to an image viewing software or gallery. When your graph is
generated, simply select the export graph image item in the contextual menu or press ENTER with I, and
you will be asked to select to which application you wish to export your image. Alternatively, it can be
exported to an embossing app connected to the embosser, and emboss the graph directly from your
BrailleNote Touch.
15.5.4 Generating Tactile Preview of a Graph
To generate a tactile preview of a graph, press SPACE with T or select the option in the contextual menu.
You will be able to feel Braille characters on the display which by themselves don’t have significant
value; their arrangement in relation to other characters as you scroll the display down with the next or
previous thumb keys, defines a shape and gradually forms a larger graphic image, such as a circle, a
diagonal, etc. To comprehend the whole shape, scroll up and down to dynamically feel the whole shape.
The faster you scroll the display with the next or previous thumb keys, the more you will be able to
comprehend the image. Imagine that you are looking at a graph paper one line at a time. Press any
cursor routing key to have the BrailleNote Touch tell you the “y” position of your cursor.
16 Reading and editing Braille documents
with KeyBRF
Opening .brf and .brl
files
BrailleNote Touch includes KeyBRF, a software designed to open .brf or .brl files. These common Braille
file types are directly written in Braille. There are two ways to open a Braille file with KeyBRF. One way is
to open KeyFiles, find your .brf or .brl file, and activate the file – the file should automatically open with
KeyBRF. Alternatively, select and activate All Applications from the main menu, then select and activate
KeyBRF. From the KeyBRF menu window, activate the Open option and find the file you wish to open.
