Amazon dreams up a drone that will understand your hand signals

Amazon was just issued a patent for a UAV that can interpret gesture and vocal commands, a device that could in theory be used to deliver packages. First spotted by GeekWire, the patent describes a drone-like device outfitted with various sensors, cameras and other equipment that could recognize gestures such as a person waving it towards them or someone shooing it away. In some very entertaining illustrations, the patent shows the UAV approaching a human who's waving at it wildly. This isn't the only device that incorporates human gesture as a control mechanism. DJI's Spark drone can be directed with arm movement and a recent Samsung patent shows a drone that can track users' eyes, heads and hands and can be controlled through gesture.
