Camera firm Snap has unveiled an autonomous flying camera device which automatically captures pictures and video which can then be shared to Snapchat. Called Pixy, the small device takes off and lands in the palm of a user’s hand and tracks the head and body of the owner in order to follow and capture content of them. The camera company confirmed the Pixy would cost 230 dollars (£184), but did not reveal if or when it will be launched. What is your thoughts about the use of drones in data privacy ?
