Contour makes cool video cameras that you can wrap around your head so that you can take video while you’re skiing or otherwise engaged in an extreme sport. But the problem with these “head cams” is that you can’t see what is really within the frame of your camera’s viewfinder.

Contour is launching its Viewfinder app and a Connect View Card today that you can use to view your camera’s picture on the screen of your iPhone or iPod Touch. If you’re nutty enough to want a head cam, then you’re probably nutty enough to want this stuff, too. It goes to show that when you are clever enough to create technology for extreme athletes, you have to go on creating stuff for them that makes those earlier inventions more useful.

I’m not sure how many people really want to do this. But those who do probably want to do it really badly. So Seattle-based Contour probably has a pretty loyal market here. The $29.99 ConnectView card is a Bluetooth device that you insert directly into the ContourGPS camera. It connects with your iPhone or iPod Touch via Bluetoooth, using the free app. Then it can stream live video from your camera to your device, giving you a viewfinder so that you don’t have to take your head cam off. As Marc Barros, chief executive of Contour says, “Hands-free video just got a lot more hands-free.”
