Phree Smart Pen: Now write on any surface, receive call, send texts

Phree a 3D Laser smart pen that lets you write on any surface created by OTM technologies has raised a whooping $1million on their kickstarter campaign which is 9 times over their goal of $100000. This smart pen writes on any surface showing  your writing in real time on your smartphone, tablet or PC screen. If you are in habit of jotting down anytime, anywhere, Phree is the smart pen for you. Phree Smart Pen is a result of over a decade of handwork and passion of Gilad Lederer co-founder OTM technologies and his passionate team.

Technology Used in Phree Smart Pen and it’s working

Phree smart pen uses patented technology called Optical Translation Measurement (OTM) that allows the smart pen to capture data written on any surface it can see and send that data to any app through Bluetooth to any Bluetooth enabled device. It uses a 3D laser interferenometer. This meter tracks the relative motion of a nearby surface by measuring the interference signal between a laser beam projected on the surface and the reflection form the surface. This system optically extracts the hand motion signals while writing and between strokes.


The signal-processing algorithms developed by OTM then translate the data collected by the smart pen’s (Phree) sensor into X-Y-Z motion data. Phree understands the motion of the writers hand in a similar way human eyes does i.e. three dimensional. The sensor of the smart pen then tracks both, the strokes made on the surface and the space between strokes as your hand moves. These motion are then recorded and sent to your smart phone, tablet which you can see in real time or later what ever is connected with smart pen.

The smart pen properly integrates with Android, iOS, windows  OS X and Linux  It supports most third party apps on Android, OSX and windows. With Android you can use Phree with almost any app like onenote, evernote, office and more like that. But that not in case of iOS, the support of Phree for iOS is limited, users can only take quick notes in iOS and will not be able to use other features.
