This is a perfect example of the importance of including the user in the user experience design. The contributions from the experts on this site and very valuable and will help you a ton, but getting input from the actual users as early as possible in any design situation will highlight important details early and avoid you having to try and retro-design ...


My father has late-stage PD and after watching him use his Mac for the last 15 years here are some thoughts in no particular order: Assume the user can't use both hands or combinations of keys. My father uses his non-dominant hand with a track-ball because it shakes less, but has to use the keyboard and click with the same hand. Try that one out yourself ...

Could there a big voice activation control on each screen? I agree with another comment that it would be really useful to test the app with people with Parkinson's.

As a matter of fact, just following common WAI- ARIA guidelines is more than enough. Keep in mind that, like many people with ...
