Hi Alastair, It’s been awhile since I’ve followed this one, but I agree with David that “motion” by itself is not clear. Most definitions of “animation” include motion or movement in the description. I get what you’re after reading what you wrote: >“Motion and scaling” are the ones we are confident are definitely issues. Colour changes, blinking and scrolling information (e.g. a teletype banner type thing) are not definitely issues, so I’d rather not try and cover those and leave it open to comments of over-reach. As written, I don’t think this scopes out scrolling marquees since there’s obviously motion there. I’m guessing you also want to exclude little things like a spinning coin? Or would that be dependent on size? Maybe use a word or phrase to refer to motion which includes position change of elements?

For motion the dictionary definition is it, scaling less so. Would “sizing” work better than scaling? “For non-essential motion or sizing animations triggered by a user action…” Would that negate the need for a definition? Cheers, -Alastair From: David MacDonald I support the new wording, with a definition for motion and scaling
