While the Android Wear emulator has been out for months, Google said at its I/O conference on Wednesday that the OS and hardware are now ready for consumers. Google is jumping into the wider wearables market with an Android-based OS designed for smartwatches and other wearables. Just like Android for phones and tablets, Android Wear is an OS that depends on OEMs to adopt and ship on their devices. Android Wear is primarily driven by voice commands and Google Now, which pops up cards it thinks would be useful on the home screen. Google's trademark "OK Google" hotword detection is here, and voice commands query Google and work the same way they do on Glass or Android. Android Wear's big leg-up on the competition is that it seamlessly works with every Android app, and unlike Samsung devices, Wear is compatible with any Android phone running 4.3 and above.
