Val Head's book addresses the question motion design students rarely get a direct answer to: when does animation actually serve the user, and when does it get in the way? Published by Rosenfeld Media in 2016, it covers timing, easing, feedback, brand personality and motion style guides, grounding each topic in UX research rather than aesthetic preference.
The UX focus makes it complementary rather than redundant to motion design practice. Where most motion design education focuses on how to animate, this book focuses on why and when. A useful counterweight for students whose instinct is always to add more motion.
