Android Wear is an open source operating system for wearables developed and maintained by Google. It is a port of the Google Now card system for notifications to smartwatches, released in early fall 2014.
Sony’s next-generation wearable, the Smartwatch 3, has recently appeared in the Google Play store at $250. It’s also available from Verizon. It has been at the IFA in Berlin, but there still isn’t a definitive release date on this particular piece of hardware.
Microsoft has recently unveiled the first Android Wear keyboard that reads your handwriting. Simply draw out your letters and it magically outputs alphanumeric characters. It’s great for writing short replies to texts.
