You Control This Tiny Drone Simply By Moving Your Hand

With just two taps of a button, lights began blinking, propellers started to swirl, and a tiny camera set about studying my face. All I had to do was release the miniature drone from my grip and it was instantly airborne. Such is the experience with the new DJI Spark, the company's smallest and cheapest drone yet. The $499 drone -- half the price of the company's high-end Mavic Pro -- is about the size of a soda can, making even the compact Mavic look gargantuan in comparison. But the Spark's most compelling feature is the ability to launch and pilot the drone entirely through hand gestures.
