[accessibleimage] Re: tactile and auditory representations of neuroimaging data

Hi Nayab,

A lot depends on the types of images that you will be working with,
and what you need to know about their content. If it is, say, about
fMRI slices with false color for any activated areas, you could use
The vOICe to import the image and toggle one of its color filters
to hear the colored areas in relation to the inactive (usually grey)
brain background. You can also apply zoom and other tricks.

Of course there will always remain problems that are hard to convey
without a lot of practice and experience, much like a sighted doctor
can see many things in an x-ray or fMRI scan that most sighted people
would not or barely notice. Hope you will find a good mix of tools.
By the way, The vOICe runs under Microsoft Windows so you would have
to copy your images from one platform to another.

Best regards,

Peter Meijer

Hello,

My name is Nayab Begum, I’m a psychology student at Aston university and
registered blind.
I am hoping to pursue a career in neuroimaging, and currently trying to
find ways to make the technique more accessible.  This will involve being
able to access complex brain images in colour as well as graphs.
I was wondering whether anyone might be able to recommend the most
appropriate assistive technology for tactile diagrams?  We’ve been looking
into electronically refreshable devices, but there doesn’t seem to be
anything on the market, and we’re not sure it would provide sufficient
level of detail.  From our research, the most advanced technology seems to
be the tiger embosser, although this also seems to have its limitations.
If anybody knows about the phantom device, and if it is sold in the UK,
that would also be very helpful.
Another option we’re looking into is converting images to sound-does
anyone have any experience with this?
Also, for the data analysis, we use matlab and scientific linux.  We’re in
the process of installing Ubuntu to use the orca speech software, but
we’re not really sure how much i twill be able to read.  If anyone has
experience with using linux with a Braille note taker, I’d also be really
interested to know how compatible it is.

We would be really grateful for any advice

Many thanks

Nayab
