If you've ever tried to play a Wii game with sunshine streaming in the window, you'll know that the TV-top sensor bar can't handle the brightness and simply stops responding.
Now, however, a new motion detector from Panasonic Electric Works promises an end to such frustrations, as it works in direct sunlight.

The unnamed detector will go on sale to hardware manufacturers next April, with Panasonic hoping to shift about 100,000 units by 2011.
Numbers like that mean it won't end up in consumer applications at first, but those could well come later if it works out in the industrial field. That might include self-parking cars or interactive billboards.
Another giveaway is the price per unit – a cool ¥1million (£6,130). Now, that would increase the console price quite a bit.
