| The makers say 
				their safe and 'friendly' drone offers a new and innovative way 
				for brands to interact with their audiences in public settings. 
				Where current advertising is often limited to displays and 
				billboards, Skye can float safely around and interact with 
				people.
 "It's a unique flying machine which is safe enough to interact 
				with. So you can touch it in flight; it's basically filled with 
				helium which provides most of the uplift," said Daniel Meier, 
				co-founder of company Aerotain which developed the Skye drone.
 
 Despite being around three metres (approx. 10 ft) in diameter, 
				Skye is extremely agile and able to perform almost any movement 
				instantaneously thanks to its four small electric motors. Its 
				engineers designed algorithms that keep it on course, even when 
				performing a range of aerial tricks.
 
 "This is where the magic happens; four motors are allowing it to 
				perform any movement, so you can really move it in the air like 
				a flying eye," Meier told Reuters while demonstrating Skye's 
				operation. "There is a computer on board which knows exactly how 
				it's orientated in the world, and then it gives commands to the 
				motors to actually align it to where you want it to be. And 
				there are four motors on it which can rotate around their axis 
				and with them you can precisely control it in any environment, 
				basically."
 
 Skye is lightweight, which combined with its small energy 
				requirements, give it a flight time of about two hours on a 
				single charge.
 
 By eliminating exposed rotor blades typical of most drones, Skye 
				makes it possible to operate around crowds without fear of 
				injury.
 
 Meier added that regular drones could also be dangerous if they 
				malfunction. "There is even one bigger issue; that is if the 
				electronics fail it will just fall down to the ground. This 
				can't happen with Skye because helium is providing the buoyancy, 
				so if ever something goes wrong it becomes a huge balloon and 
				people could play with it," he said.
 
 Aerotain says its technology could disrupt the advertising 
				industry by allowing companies to engage directly with the 
				public in a way never seen before. At public events, such as a 
				sports game or concert, Skye can autonomously float above the 
				crowds or with a pilot at the controls. Skye's surface can be 
				designed individually, for instance to depict a product or to 
				show the name of a brand, with its uniqueness naturally 
				attracting people's attention. It's also strong enough to carry 
				on-board cameras for live streaming and aerial cinematography.
 
 Skye is currently on display in the Swiss Pavilion at the CeBIT 
				2016 technology fair in Hanover, Germany.
