We’re still waiting for Apple to introduce its long-rumored iWatch. But Google today showed what it plans for mobile devices, beginning with watches including ones made by LG, HTC, Samsung and Motorola: The Android Wear software integrates voice commands and the kinds of location-based information that owners of Android smartphones and tablets access from their Google Now cards. “Just say ‘Ok Google’ to ask questions, like how many calories are in an avocado, what time your flight leaves, and the score of the game,” the company says in a blog post. “Or say “Ok Google” to get stuff done, like calling a taxi, sending a text, making a restaurant reservation or setting an alarm.” Android watches also will feed commands to smartphones and TVs. This company video illustrates what it has in mind.
