Xbox Live Vision is a device that connects to your Xbox gaming console and allows you to video chat with your friends while you play games. It looks like a little camera that you can place on top of your TV or monitor. When you want to use it, you plug it into your Xbox and turn it on. It then captures your image and allows you to transmit it to others over the internet, so they can see you while you play. You can also use it to take pictures of yourself and add them to your gamer profile. It's kind of like having a little TV studio in your living room that lets you share your gaming experiences with your friends.
