The Jigabot AIMe is an automated camera controller that can compose a shot to keep you in frame. AIMe uses a beacon called EmIT which can be tracked by multiple AIMes, despite being a small 2-inch square.
The pole for your camera is getting better and better with the Quik Pod DSLR/POV Ultra and Quik Pod Explorer 3. These are easy ways to get a self portrait and a better perspective of your action. Though this type of camera support has been around for some time now, seeing the updated versions is pretty cool.
