Under the Hood: The Proprietary Tracking Technology Behind the Mentis™ Pen
Welcome to Part 2 of our exclusive 7-page deep-dive series on the future of digital writing technology. If you missed our first article comparing keyboards to handwriting, click here to catch up!
Now in its fourth generation, the Mentis™ Pen eliminates the need for older, unreliable acoustic or ultrasonic triangulation methods that traditionally suffered from lag. Instead, it utilizes a proprietary, independent optical coordinate capture system engineered with absolute spatial precision.
The physical mechanics rely on a high-speed, downward-facing infrared camera sensor integrated near the nib, positioned directly behind the pen’s writing tip. As the user moves across the tracking surface, this camera samples an invisible, non-repeating micro-dot coordinate grid matrix layered directly on the specialized paper or tablet canvas.
An internal Digital Signal Processor processes these raw image packets in real time, calculating precise 2D vector coordinate frames. Simultaneously, internal hardware measures physical writing force, tracking up to 8,192 discrete levels of pressure sensitivity to accurately mirror your true line weight digitally. This raw spatial and pressure data is instantly compiled into a clean digital vector format to be saved to internal storage or streamed via Bluetooth to your companion device.
