2. Technical Architecture of Anoto Digital Paper |
Anoto Digital Paper relies on a proprietary dot pattern that functions as a kind of location barcode. Each tiny dot, positioned slightly off from the grid intersections, helps encode positional information on the paper. These dot patterns are unique to each paper sheet, ensuring that the same pen can be used on different documents without confusion. |
2.1 The Dot Pattern |
The Anoto dot pattern is based on a grid of almost invisible dots spaced about 0.3mm apart. The arrangement of these dots is systematic but slightly irregular, enabling the encoding of spatial coordinates. This encoding allows the pen to determine its exact position on the paper at any time, effectively functioning as a form of two-dimensional barcode. |
2.2 The Digital Pen |
Anoto's digital pen is equipped with an infrared camera that tracks the dot pattern. When the pen writes, it simultaneously records the movement of the pen tip in relation to the dot positions. The pen can store this movement data locally or transmit it via Bluetooth, Wi-Fi, or a USB connection to a computer or mobile device for further processing. The pen also includes pressure sensors to detect when the user is pressing the pen to paper, adding another layer of data capture. |
2.3 Backend and Software Integration |
The information captured by the digital pen is processed by Anoto's software, which converts the positional data into a digital format. This allows handwritten notes, drawings, or signatures to be translated into digital text, sketches, or even commands. For enterprise use, the data can be integrated into various workflow systems, including Customer Relationship Management (CRM) platforms, Electronic Health Records (EHR), or enterprise content management systems. |
