Google reveals Android Wear operating system: Linux rules
Android Wear is a version of Android which is optimized for wearable devices such as smartwatches. One of the core components of Android Wear will be Google Now. Just like Google Glass, users will be able to say “Ok Google” to activate the ‘HAL’ and ask questions. Since it will work with Google Now, it will have access to your travel and Amazon orders so you can check status of your flight or package. You will also be able to get generic answers like scores from ongoing machine. Anything that you use Google Now for will be able to use with Android Wearable.
