<p>Conversion between image formats is relatively well automated.
You should be able to convert whatever file you have to a format
that your tactile device can accept. It doesn't follow,
unfortunately, that the resulting tactile graphic will be
meaningful and comprehensible to the tactile reader.</p>
<p>Both Graphiti and Monarch support manipulation of the tactile
graphic, once displayed. Particularly interesting is the option to
rotate the image by 90 degrees, as in landscape orientation.</p>
<p>On the subject of other devices, numerous tactile actuation
methods are disclosed in patents that have been issued during the
last several decades. There's an enormous distance between a
patent application and hardware that is available to the public,
as the history of this field has suggested. I don't know which
projects are currently active, or which have a real prospect of
commercial viability.<br>

<p class="MsoNormal"><span style="font-size:11.0pt">Unfortunately
there is not a standard format yet. Most of the companies
are doing their own thing. Monarch and Graphiti can handle
different file format but they can be regular images like
jpeg, png, bmp. Some o like the grpahiti have a csv file
style as well that you can make a text file to make the dots
at different highest and even cause them to blink. All of
the current ones has some way to take regular graphics and
show it to varying levels of success. All of them have ways
to change filters for either color or brightness or grey
scale and ways to invert from light to dark because
depending on hwo the tactile comes out it looks better
inverted or not.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt">There are
other displays like the Metech one, the Dot which uses the
same dots as the monarch. There is the Kadence and the
Kadence has some other displays that the company is working
on that uses the same dots. When we started working on the
Graphiti in before 2016 I don’t have the exact date it was
between 2013 and 2016 I can find it but just don’t have it
in my head. When we started work on it there were 65
different companies working on different technologies. I
might go back and revise that list and see how many I can
get a hold of now days.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt">There is

explosions. Pretty crazy if you ask me.<o:p></o:p></span></p>

Yes I have seen it. This is an off shoot of University of
Michigan and was<br>
called the Holy Braille. If you do a search you can
probably find a video<br>
on it. It runs on Air and the under lying technology
has a rubber mat<br>
like material that pushes up pins. It can run on a air
pump or CO2<br>
cartridge. It has micro vacuoles that open and close to
move the pins up<br>
and down. I like how compact the material is and I have
helped with some of<br>
my knowledge in the past . I have my worries about its
power source but they<br>
are showing the technology now and it can be resized to
make larger<br>
displays. I say the more types of technologies out there
the better. <br>
