Android Wear adds a screen to your phone to simplify your life.

Google is heavily promoting that it aims to simplify your life at Google I/O and this year Android Wear joins the list to make wearables smarter to make your life easier. The aim of Android Wear is to be contextually aware, voice enabled, seamless, and mobile first. Android Wear brings glanceable, contextual notification from your phone to your wrist so that you can perform tasks quickly and easily on the go.

On stage, Google says that style is important and that Android Wear will support both square and circular screens. People check their phones on average 125 times a day and Android Wear will address that by showing relevant information on your wrist. Android Wear will have an always-on display, similar to how a watch works, so you don't have to turn it on when you need it.

Android Wear is controlled by gestures. Swiping left and right will scroll you through notifications and cards, swiping up and down will bring up different commands. You can also customize and change your watch faces as well.

Additionally, notifications will sync between a phone and a watch so when you're dismissing a notification on one, it disappears on the other as well. When you get a notification, your watch will vibrate to let you know.

Android Wear will show information like when your package will be delivered, and using the GPS location from your phone, when you get home, Android Wear will remind you to check for that package if you were gone all day. It could also track footsteps and allows you to use the microphone to activate Google Now and Google search.

Android Wear shows notifications

Android Wear watches will be water resistant at launch.

Google says the Android Wear SDK will be available today to developers and developers can code apps so that these apps deliver notifications to Android Wear automatically.

Voice will be a big component of Android Wear and Google demonstrated how Android Wear can be used to summon a ride using Lyft's ride service. When a user arrives at a destination, voice can be used to leave the Lyft driver a rating as well.
