After reading a few posts about not liking to only have audio and/or audio/video content it got me thinking about more then just people without speakers or headphones. What if physically a person can't see or hear, how would they have access to support items that are only screencasted. This article from National Network of Libraries of Medicine-Pacific Northwest Region helps us to think about making sure our web content is accessible to all. While it is not just about screencasts I think it is pertinent to the discussion because we can't just think of our "normal" or "regular" users, we need to think of all our users.
Actually I thought about that
Actually I thought about that a lot. So much of the design of the web has to do with people who are not deaf or blind.
When I went to experiment with sound I realized I was microphone disabled. So that meant I had to do the whole thing in captions (or deal with loading all the software onto another computer etc etc). I am happy to say my screencast has no audio, well except for the sound of the typing.
Yes, it's important to keep
Yes, it's important to keep in mind that people's needs and capabilities are very diverse. From interning at the SJSU King library, I know that their screencasts must to adhere to certain standards (screen dimensions, text and background color, closed captions, etc.) in order to be ADA-compliant.
