Would it be hard to build a mouse emulator TOH? [not relevant]
If the phone is connected to a laptop for charging and data transfer then it could be used as a mouse too, right? An Other Half with an optical sensor, some software (for onscreen buttons) and voila! A mouse for your laptop.
And I would never forget to bring my mouse again...
Or, you could use the optical sensor that's already there: the camera. The "Mouse TOH" would only need to provide light and elevate the camera a bit from the surface (because if the camera lens lies right on the surface there's no room for light to get in), and software would detect the movement.
This would hardly make a very good mouse though, as the camera is not the optimal sensor for this kind of use... Probably would make more sense to include a proper optical sensor like you suggested :) But it could be done as a simple and cheap solution.
