A little background first
At the company I work for, we're working on an e-learning application, aimed (exclusively) at dentists and their teams. While trying to decide how important accessibility standards are to us, we started to consider dropping support for keyboard navigation.
I'm trying to come up with a list of circumstances that could lead to the use of a keyboard as primary (only) navigation instead of a mouse.
- Certain/muscle coordination affecting disabilities
- Blind/limited visibility
- Broken input device (mouse, trackball, etc)
- Preference (power-users)
I'm sure I'm missing a bunch, and I'd love to add some to this list.
