The design was teased first in the general keynote during the 360-degree video demo for the living room. The presenter speaks into a Shield TV remote to do a voice search for 360-degree videos. The UI of the search results looked similar, but notably different from the current Leanback template.
The results have a white shadow on a dark background, contrasting with the dark shadows standard with material design. The sidebar has a home and a playlists icon. There’s also settings and an overflow icon. The user’s profile icon appears in the top-left corner, perhaps making account switching more convenient, or perhaps not.
To make certain that this new UI is coming to Android TV specifically, take a look at a clip from the “What’s New in Android TV” session, where they are opening a video from the new launcher into YouTube. Although it appears for a split-second before buffering the video, you can see the same user interface and style.
This new design will likely launch soon, with the 360-degree video feature. At that time we will be able to better assess the new design and how it may improve upon the current interface.
