In the future we may wave at our smartphones

USA TODAY's Jefferson Graham thinks the new gesture controlled DJI Spark drone is the wave of the future in computing. Today, we move to the hands. In one of the most jaw-dropping tech demos of the year, drone manufacturer DJI this week showed off a new quadcopter that can be flown with hand gestures. Move your palm left to fly that way, extend your hand to land it. As someone who spends a lot of time flying drones and juggling with video-game like controllers to operate them, this is the holy grail. No more worries about connections and keeping my head down to operate--just wave my hands in the air and let the drone soar.
