Digital devices are great, but they can also be annoying when it comes to writing or drawing. Most of the time you must rely on your fingertips to do the typing or drawing for you, and what you wanted to write or draw might not come out the way you imagined. A new pen called “Phree”, created by Israeli company called OTM Technologies, aims to change the dependency that most of us have when it comes to writing or drawing in digital form.

The Phree pen looks a lot like a regular pen in both size and shape. The difference is that you can use the Phree pen to write on any surface (from a table to a wall), and then transfer that writing directly to your target device.

Phree uses a sensor called a 3D laser interferometer (激光干涉仪). The laser beams are projected (投影) on the surface and they will be reflected back to the interferometer. By analyzing these beams’ tracks, the laser interferometer measures the hand motion while writing.

The pen connects with your phone via a Bluetooth. Phree can be used to take notes using various applications on the target device. The notes will appear on the target device whenever you open it. You can even receive, write and send text messages using the device display (显示装置) and it can function as an earphone. Phree can also be used as a regular computer mouse whenever it is connected to a target device. The device can also be used as ID equipment as it can precisely analyze the way a person writes.

“We see Phree as a standard input device in the mobile world, in the same way the mouse became a standard part of PC use. We also see benefits to emerging technologies like AR and VR headsets, interactive TV, and IoT (Internet of Things ).” Gilad Lederer, co-founder of OTM Technologies said.
