Subject: NVDA + Flash and another question on PDF
No previous message | Next message →
Hi wonderful, helpful forum members,
Does anyone on this forum know about how well NVDA handles Flash? Our project has some training done in Flash and they are following accessibility guidance around Flash. JAWS seems to work okay, but I am seeing different results with NVDA so am not sure if NVDA + accessible Flash is actually possible.
My second question is regarding the built in reader in Adobe PDF. My experience with the built-in reader has been horrible. Do most blind/vision-impaired users tend to use their own screen readers vs. the built-in reader? I've searched but could not find navigation tips for using the built-in reader and when I click the up/down or right/left arrows the document jumps all over the place.
Thank you,
Robbie Ann Kohn

Hi Robbie,
Adobe Reader (if that's what you are referring to) does not have something built-in that I would call a reader targeting people with disabilities or special needs.
It does have a text-to-speech feature but I do not think many would claim it is especially good. It is definitely not a substitute for assistive technology.
Adobe Reader (on Windows) nevertheless exposes an internal programming interface to screen reader programs or other assistive technology. A screen reader - like JAWS or NVDA - can make use of that programming interface and deliver the actual functionality, like accessing and interacting with content in PDF files, assuming they are tagged PDF files.
In addition, for any PDF files that are not tagged already, Adobe Reader (and Adobe Acrobat) will offer to create tags on the fly. While this is based on heuristics, and will work better or not so good, depending on the PDF file, it enables some access to content that has not been prepared with accessibility in mind.
Regarding the quality of PDF access - I'd say that JAWS and NVDA are similar, and both are quite good at it. I can't comment on other screen readers.
