Amazon patents delivery drones that react to people screaming

Amazon's drones could soon have a way to deal with unhappy customers who aren't happy with their deliveries. The firm has filed a patent to embed sensors in its drones that could react to voice commands and hand movements. This means the UAVs could respond to people screaming, waving their hands and making frantic or rude gestures during a delivery. Based on customer reactions, the drones could release the package, change their flight path or ask the human down below a question about the delivery, the patent suggests. Entitled'Human interaction with unmanned aerial vehicles', the patent was issued to Amazon on 20 March by the US Patent and Trademark Office. Diagrams show the drone reading human body language with commands such as'Receive human gesture' and'access gesture database', writes Los Angeles Times.
