You might wonder what the difference is between a drone with a camera and a hover camera. The main difference is that a drone has to be steered, but a hover camera navigates on its own. You switch it on and let it go, and it hovers around you making videos with its integrated 13 megapixel camera. A separate camera takes pictures of the ground for orientation. The Hover Camera determines its position using an accelerometer and a gyroscope.
The ultimate version will have a panoramic scan mode so it can detect all the faces in its vicinity. The pictures are sent to the smartphone of the Hover Camera owner, who can select a person to be followed by the camera. The Hover Camera will be priced between 500 and 1,000 dollars.
