"Write" on any surface, Phree creates crisp facsimile of one's handwriting on your device

Ever had the feeling of wanting to take notes but not having a surface to do it on? The creators of Phree, a stylus that can record your scribblings on any writing surface using motion-sensing technology, feel your pain. Their solution allows you to “write” on any surface, interacting with the world more directly and practicing the endangered art of handwriting. Phree's crowdfunding campaign on Kickstarter begins today.

The stylus's breakthrough characteristic is its use of a technology called Optical Translation Measurement, which tracks motion over a much wider range of surfaces and with a wider dynamic range than other kinds of motion sensing. It uses a compact 3D laser interferometer (a laser beam projected on the writing surface that creates reflection). A small processor then translates this information to X-Y-Z motion. This creates a crisp facsimile of one's handwriting on your device.
