Is it time for the Internet giant to expand into the world of physical gadgets? I guess Callum Peden, a UK designer, thinks so. He's created the concept of a "Google Vision" device, which basically takes Google Maps to a more personal level.The concept brings three features into one handheld gadget -- a retractable LCD screen, a digital camera, and GPS functionality. What this would allow you to do is to take pictures of anything and it will automatically map it. So if you can't remember where that doctor's office is, you can just pull out your Google Vision, provided that you've snapped a picture of it previously.It could also apparently be able to connect wirelessly to the Internet and recognize nearby landmarks and download information about the area, so while you're on vacation it could turn into a virtual tour guide. It's quite an interesting concept, and something that I think has a shot of making it to retail, though it may take a while.
