Google Cast UX
Google Cast enables users to fling content from their phone their TV or audio device. For the most part, the Cast user experience is very brief, but to make it great requires each app to implement it the same way.
At Google I/O 2015, I shared guidelines and best practices for enabling Google Cast in your app. I also walk through some examples to demonstrate specific concepts.
If you ready to get started, check out the Cast UX Guidelines that I helped publish for developers.
