Here is a simple idea I thought of. Most people who’s main computer is a laptop use a separate mouse because it can be awkward using a touchpad all day. A lot of  people who have these laptops also have mobile phones with bluetooth and a camera. Instead of using a separate mouse, why doesn’t someone adapt the camera sensor of a mobile phone to work as an bluetooth optical mouse? I don’t think it’s a huge design leap. You heard it here first!
