set off an avalanche of news today when it announced the specifics of its new wearables SDK. A rumbling mass of “me, too!” announcements followed, as individual companies disclosed their own plans for wearable devices.

have yet to see what developers plan to do with the Android ar developer preview SDK. However, thanks to the intrepid code diggers at Android lice, we have some tantalizing glimpses of what to expect. Here’s what caught our eye in their report.

Say goodbye to angular watch displays

Voila! It’s an emulation of a round watch display, like the one featured on the as-of-yet-released Motorola Moto 360. Developers can tweak their apps to work within the confines of this relatively peculiar shape. Does it mean we might expect other shapes to crop up in the future—a heart shape, perhaps? Unlikely. But at the very least, we’re no longer limited to rectangular watch displays.

Everything is a card

You start off at the Home screen, which houses the clock app, voice input button, most recent app, but the user interface notifications stack appear similar to the Cards contained within Android’s Search app. expect that the Android-powered smartwatches that follow will essentially be an extension of Now’s capabilities, though it’ll also be interesting to see how third-party companies will integrate with it.

So… you like gestures?

Buttons are totally passé. Touch gestures are where it’s at. You can scroll through notifications by flicking up down, or peruse through the various actions for each app by swiping from right to left. According to Android lice, each action button occupies a full screen, so it’s all fairly self-explanatory. 

Voice control remains mysterious

The voice functionality didn’t work when Android lice delved into the developer preview SDK. For now, we can just offer up this YouTube video from the Android Development team on what to expect.
