Lost in the supermarket? Can no longer shop happily? Fret no more, if British researchers have their way.

A team led by Paul Watson at Newcastle University is working on GPS navigators that would help elderly people find their way through supermarket aisles, according to the Daily Telegraph.

"Many older people lack the confidence to maintain 'normal' walking habits," he tells the newspaper. "This is often due to worries about getting lost in unfamiliar, new or changing environments."

Watson's also working on an "ambient kitchen" that would help people with Alzheimer's disease remember where they put the sugar.

Sensors on drawers and cupboards would feed into a computer, which would remind users where things are if it sensed they were getting confused.
