Gaming technology used in drone planes

It looks like the ultimate new video game: the operator on the comfortable leather chair uses dextrous thumbs on a hand-held console to manoeuvre an aircraft, whose trajectory is shown on three large flat screens.

But the chair is for a qualified pilot and the landscape on the screen is downtown Baghdad - US defence company Raytheon Inc. is providing a first glimpse of its new control system for unmanned aerial vehicles, or UAVs.

The company says its Universal Control System, which uses some hardware from the gaming world, will shorten training time and help prevent crashes of the expensive drones by providing a more interactive experience for the pilot.

"We wanted the human to get into a cockpit and feel they are stepping into the system," said Mark Bigham, director of business development, at the Farnborough International Airshow outside London.

While older stations used just a keyboard, single screen and joystick, a key factor for Raytheon was making the system more intuitive, replacing key strokes with a game console, after talking with experts and discovering thumbs are the most energy efficient and accurate way to control a craft.

The leather chair is fully adaptable to individual users, who can also control a heating and cooling duct above their head at the touch of a switch.

And in a move away from what Bigham calls the "soda straw" view of most pilots of UAVs, the screens are augmented with digital images that provide a near 180-degree view

Other data, such as the health of the craft and where troops are located, is provided on a fourth screen, in much the same way that video games provide extra on-screen information on character health and ammunition levels.

Raytheon, headquartered in Waltham, Massachusetts, is hoping to capitalize on the rapidly growing use of umanned aerial vehicles in both military operations and civil environments around the world - the overall global market is set to go from US$3.5 billion to some US$55 billion in just 10 years, according to the Teal Group.

The war on terror has spurred the use of drones in combat areas, with unmanned aircraft currently flown by the US Air Force and the Royal Air Force in both Iraq and Afghanistan.
