DIGITAL PEN
A simple device that records what you write

This pen allows you to digitally record your writing and drawing,
without the need for special paper or any bulky hardware.

OPERATION
Remove the cap and clip it onto the top of whichever surface you please.
From here the cap observes the position of the pen and the pressure of its stroke.
The pen emits an infrared signal from near its tip when writing.
The cap watches this tip with its two flat fresnel lenses, and locates it through triangulation.
or it can be just used as a normal pen…

Once the cap is removed, it is attached to the page using its spring loaded clip.
The pen is then opened out to its full length.
Each time the cap is re-clipped, a new digital image is created.

Carry everything you need for digital recording and downloading on your person.
No need for a special docking station, special paper, tablet, wires or anything else.
To recharge the pen or download its store of image files, use the supplied credit card.

The method for downloading or recharging couldn't be simpler.
Take the plastic credit card, fold it into three, clip on the cap and insert into the USB slot.
The thickness of the double folded card is the same as the bottom part of a standard USB slot.
