- 52. Broad generaliza4ons/good guesses • Anima)on should serve a purpose. • Be consistent • Downgrade to fades • Use mo)on blur on fast, large moving elements • An)cipate and signal oncoming anima)ons • Reduce autoplay • No one likes parallax anymore
- 53. Issues facing standardizing accessibility • Extrapola)ng from unrelated research. • Research from homogenous sources. • Humans are inherently different.
- 54. It appears every user with Ves)bular disabili)es is unique and its hard to nail down a group of provoca)ve ac)ons that would significantly address a lot of the issues without significant impact on design. “ David MacDonald Invited Expert at the WCAG
