Google announced several updates to its smartwatch operating system Android Wear during its I/O 2015 keynote. These include a mode to more easily access content without using battery life, scrolling between content using your wrist and the ability to recognize emojis drawn by users.

Google introduced its Always On mode at the top of its Android Wear updates announcement during I/O 2015. This mode allows you to see and access whatever it is you have on your smartwatch screen, whether it's the time, a shopping list or Google Maps, in a low-power mode so that the app doesn't eat up too much of your battery.

This new batch of Android Wear updates also includes the ability to use wrist gestures for hands-free scrolling through the various apps on your smartwatch, literally with just a flick of the wrist. Your smartwatch will also be able to recognize emojis drawn by you and send the official corresponding symbol to the device of whomever you're sending it to.

Android Wear will also be updated with a new launcher that will allow you to access the more than 4,000 apps now built specifically for Android Wear on your smart watch, which includes everything from Amazon to Foursquare to Spotify.

These updates are expected to arrive with the latest release of Android Wear rolling out over the next few weeks. More Android Wear watches are also expected to launch by the end of the year.
