Growing up in the country riding dirt bikes all the time I can tell you that a pair of goggles is required if you like being able to see. A bunch of people that ride off-road and do other sports like skiing that wear goggles also want to show off their skills on video to their friends that weren't around. The catch is that it's hard to find a camera that can withstand off road use and is small enough that it's not a bother to the user.
Liquid image has unveiled a new set of goggles called the impact series that has a 1080p camcorder integrated into the frames. This same company makes the line of scuba masks that have video cameras inside. The Impact series comes in black or red colors and the video camera is in the center of the goggles right above the bridge of the nose for a perfect POV.
The field of view is 136-degrees to take in all that the rider sees. The camera will record 1080p resolution video at 30 fps and can record 60 fps video at 720p resolution. It can also take still shots at 12MP resolution. The video and photos are stored to a microSD card and the goggles ship with a 4GB card and support cards up to 32GB. Pricing and availability for the goggles is unknown at this time.
