Hi Ange,
Thanks, I hadn't even thought about separate instructions for trackpads or screen readers! How much detail do you give for each option? Do you point out everything on the player or just a few things? I'm not sure where to be descriptive and where to trust that my audience knows their chosen technology.
Hi Phoenix,
In general, I would say rule of thumb: if you do not know your audience, never assume.
To satisfy client preferences for a comprehensive, catch-all overview, the way I set it up is: after choosing an option the user is taken to a slide that explains all the features of the player that are applicable to their choice: e.g. where it is; what it does; how to access/ interact with it... . This way knowing whether the user is familiar or not doesn't present a problem, and it's not an annoying frustration if they are familiar, they can easily skip it. Note: I always make the seek bar accessible on this slide, and I always have the Continue button enabled so the user can skip the slide and start the course if they realize they already have the know-how.
