This pencil has two modes: 1. write, 2. work as a wireless mouse.
Using this mouse someone could copy the examination question for a cooperating partner outside the door, and the partner could then help solving the problem by translating it back to the person where the examination takes place...
Copying
in examinations is a bad idea, but that would work, and this kind of pen could have many other uses.
Most fortuitous.

So, sort of like a stylus, but with the sensor in the stylus
rather than in a trackpad, a wireless link and an ability to
write? Yes, that would be neat. |

You might *just* be able to do this optically, somewhat
like an optical mouse, with fibreoptics emerging near the
pencil point (or, better, pen nib). Alternatively,
accelerometers in the body of the pen might work. |

But this wouldn't work as an exam cheating tool - you
could transmit from the exam room, but how do you get
the information back? |
|
| |
//how do you get the information back// small lead weights within the pencil body, shifted by servo motors. The limp-wristed user draws the pencil smoothly from left to right, and the moving weights wiggle it enough to produce lettering. |
|
| |
//how do you get the information back?// pocm's lead weight system, combined with a segway-like gyroscopic balance, and the cheater's pen can fill in the test answers by itself |

Dictate via radio is an easy way. |

Pretty sure you need a fixed angle of reflectance. Why not just have a scanner pen? |
|
| |
If the ink is clear until it comes into contact with air, then we could optically track the rotation of the pen's ball-point, from inside the pen. |
|
| |
Of course, this wouldn't detect movements that occur when the pen isn't in contact with the paper, so it would have to be combined with MB's accelerometers in the body of the pen. |
