Phree – Make the world your paper: The world’s first unrestricted, high resolution, write-virtually-anywhere mobile input device

iCrowdNewswire - Jun 3, 2015

Phree – Make the world your paper


Phree™ is the world’s first unrestricted, high resolution, write-virtually-anywhere mobile input device.

We live in a world of screens. But writing or drawing on them isn’t always spontaneous and doesn’t always feel natural, especially if they’re put away somewhere. Screens are useful, sure. We love our screens, too. But sometimes, they’re just too limiting.

Phree lets you write, draw, annotate, and express yourself in countless other ways. On virtually any surface.

 Even here. (Yes, here.)

And when we say “virtually any surface,” this is just one more example of what we mean.

Phree™ will easily connect to all your devices: phone, tablet, laptop, TV…anything with a Bluetooth connection. And Phree is compatible with software and apps like Office, OneNote, EverNote, Acrobat, Google Handwriting Keyboard, Viber and more. So you can instantly sketch or jot down ideas, notes, thoughts, email addresses and phone numbers…whatever crosses your mind!

 You’ll use Phree in ways you never expected.

It even functions as a headset and has an integrated screen for brief texts. When you get one, just write back and send.

 Phree lets you go beyond the screen to express yourself more quickly and easily.

Phree in the News

User quotes by people who’ve tried Phree prototypes in NYC, London, San Francisco and Israel:

“I love the way Phree feels in my hand.”

“It feels like using a pencil.”

“I’m surprised and very pleased with the weight and feel of Phree.”

“Phree seems like a natural extension of the smartphone. Like it’s been there all along.”

How was Phree born?

All of us have amazing dexterity and control over a tool held by our fingers – be it a pen, pencil or scalpel. We learn to exercise this control at such a young age and practice it so often that it becomes truly effortless.

For real-time on-screen digital ink rendering, the latency between our writing motion and the perceived ink trace needs to be an eye-blink – nearly instantaneous – for it to feel “right.” We also want to be able to write and sketch wherever we are and whenever we want to. When you want to jot something down, you don’t want to unlock your phone, open an app and wait.

Well, we cracked this.

At OTM Technologies, we invented our Optical Translation Measurement (OTM) technology that precisely tracks hand motion across virtually any surface, in a wide dynamic range. We managed to engineer and build a compact, low-cost optical sensor that fits at the tip of a pen-like device. The combination of one-of-a-kind, breakthrough technology and ergonomic, user-friendly design brings you Phree.

The Design

A lot of thought and prototyping was invested in Phree to ensure a great user experience. It’s thin and it has an oval cross section, so it’s both useful and comfortable. And when you hold Phree in a writing position, the touch display always faces you for easy activation. Just touch to change from a pen to a highlighter. Or from red to blue. Or from messaging to dialing.


Length- 142mm     Width-18mm   Weight- 30 gr

Thickness- 8.5mm

Color: Phree prototypes are in Black, Graphite, Silver and Gold. We will survey backers during the campaign to determine color preference.

The Case

We designed a functional and practical case to carry and charge Phree. The case has embedded wireless charging – you charge your Phree by simply putting it in its case and placing the case on a wireless charging pad (not included). 

The case cap attaches magnetically to the body of the case to form an adjustable stand for any smartphone. Just place your phone in the stand, begin writing or drawing off-screen with Phree and voilà – you have an instant mobile workstation that actually works. Phree can be ordered with or without a case.

Transforming the case into a mobile workstation: 1. Closed case 2. Remove cap 3. Attach cap to base 4. Place phone in holder

How does Phree™ work?

The patented OTM sensor is a compact 3D laser interferometer. It tracks the relative motion of a nearby surface by measuring the interference signal between a laser beam projected on the surface and the reflections from the surface. The beauty of this system is that it extracts the motion signal optically.

The signal is then translated to X-Y-Z motion information by our signal-processing algorithms running on a very small, integrated electronics component.

The OTM sensor can measure the motion of any object that we can see with our eyes, in three dimensions, with extremely high resolution and very high accuracy, up to a distance of about one inch from the object. It therefore continues to measure hand motion between strokes. The sensor uses the same laser used in optical mice and is eye-safe at any distance.

Sensor Specs

 Phree Overview

Phree’s graphical touch-screen is used for Bluetooth connection and context-sensitive interaction with various applications. The standard icons on the display include notifications – messages and phone calls. When used with specific applications the display will change to allow quick interaction with common features. For note taking, for example, the display may show pen, eraser, and highlighter. The touch panel recognizes single fingers and swipe left/right.

Opportunities for Developers

An open API allows developers to make use of the screen for specific interaction with their applications. The API provides access to additional sensor information such as vertical (Z) motion data, as well as access to the accelerometer.

With our $749 DEVELOPER PACKAGE REWARD, developers get the earliest production version of Phree and its case, with our SDK (Software Development Kit including hardware) and technical support to optimize the use of Phree with their apps. The SDK will be delivered well ahead of our first product shipments.  Be a part of our developers community.

Opportunities for Partners

We would love to cooperate with partners to expand the use of Phree.

Phree enhances human interaction in areas such as Augmented Reality (AR) and Virtual Reality (VR), Biometric identification, Gaming, Interactive TV, and more.

Both AR and VR headsets present input challenges that call for creative solutions. Phree offers a unique ability to use the amazing hand-eye coordination we naturally possess to get fine control of objects in the AR/VR world even when we do not look at or see our hand.

For Biometric identification, Phree brings the ability to sign and write passwords anywhere, at high resolution, and by adding tracking of the tip motion also between strokes.

Phree’s use as gaming controller or remote control for interactive TV are additional areas where we see large partnering opportunities.

We welcome interested parties to make use of our $10,000 PARTNER WITH US REWARD to explore your creative ideas.

Thanks in advance for your support!


We have been developing our OTM technology for over a decade, meticulously perfecting the OTM sensor’s performance and preparing it for mass production while patiently waiting for the market window of opportunity to open for Phree. With the recent surge in the mobile Internet, wearables and personalized messaging, we believe the time has come to free the Phree and make it mainstream.

All the founders of our company have extensive physics and engineering backgrounds. We have assembled a multidisciplinary team of professionals to bring Phree to the market. We carefully assessed all the challenges and risks that are inherent in any project like this. We overcame significant technological barriers and are very pleased with Phree’s performance. Still, we have our work cut out for us to make sure that Phree is a well-engineered product that is a joy to own and use and that can be manufactured in large numbers for a reasonable price. We are working on these things day and night.

The challenges we’re facing now are the ones that are an inevitable part of the process of taking any working high-tech prototype into mass production. The prototype electronics, now consisting of large development boards, are being transformed to small scale components that will fit the product design. Additional challenges include system integration with the various components, establishing the production process and most importantly, ensuring that we deliver the best user experience with Phree. We firmly believe that we will be able to meet these challenges and deliver Phree to our backers with complete satisfaction. From the launch of this campaign until delivery, we promise to keep you all fully updated on our work and progress. Should any unexpected issues or delays arise, we will keep you in the loop and handle it with transparency.
