OTM technologies invented an optical translation measurement (OTM) sensor that precisely tracks hand motion across virtually any surface, in a wide dynamic range. they managed to engineer and build a compact, low-cost optical sensor that fits at the tip of a pen-like device. the combination of breakthrough technology and ergonomic, the company designed a user-friendly pen named ‘phree’. 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 signal is then translated to X-Y-Z motion information by our signal-processing algorithms running on a very small, integrated electronics component. 

size of a traditional pen

it’s thin and it has an oval cross section, so it’s both useful and comfortable. the touch display always faces the user for easy activation and with touch sensitivity the pen can change to a highlighter, red, blue colors, or even from messaging to dialing capabilities. it’s thin and it has an oval cross section with a touch-screen for context-sensitive interaction with various applications that connects to any smartphone with bluetooth technology. the display shows icons for 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. with a successful kickstarter campaign, OTM plans to ship ‘phree’ by march 2016.
