Professor Bob Stone loves the smell of napalm in the morning.
He's less keen on raw sewage, burning vegetation and diesel exhaust, but at the click of a mouse any and all can be wafting through his office at Birmingham University.
It's just one of the techniques the computer scientist is using to make video games more realistic. Stone is helping to develop technology likely to end up in home games consoles to create realistic "smell effects."
Players will experience the odors of, say, the racetrack or the battlefield. His research also has a more immediate goal: to train future recruits to the British military.
Stone, a member of the university's school of engineering, is being part-funded by the Ministry of Defense to build, as he puts it, "serious" games.
