Digital Pen

edit

The Digital Pen is an ink pen combined with a digital camera that digitally records everything that is written. It works by recognizing a non-repeating dot pattern printed on the paper. The non-repeating nature of the pattern means that the pen is able to determine which page is being written on, and where on the page the pen is.

The dot pattern can be printed on a professional offset printing press or on a laser printer. Dots are printed in black; other colors of ink are invisible to the pen's IR sensor. On a color laser printer, CMY can be mixed to produce a near-black color that is human-readable. For offset printing, Anoto developed an ink color called "Anoto substitute black", a non-carbon-based black ink that is invisible in the IR region, allowing the user to include human-readable black marks with the dot pattern without interference.

While some of Anoto's licensees have targeted the consumer sector, with, for example, learning toys, most licensees sell their products to providers who put together customized vertical market systems. Anoto also sells a software development kit (SDK), numerous software applications, and the Anoto Forms Solution (AFS). In addition, Anoto sells an ASIC design for the image processing component of the pen; most pen licensees use the same basic design of optical assembly and pen internals.

 
Simplified principle of the Anoto digital pen.
The camera identifies a 6×6 matrix of dots, each displaced from the blue grid (not printed) in one of 4 directions.
The combinations of relative displacements of a 6-bit de Bruijn sequence between the columns, and between the rows gives its absolute position on the digital paper.

Models include:

C.AI

edit

Cognitive Artificial Intelligence is a cloud based AI program designed for offline education use. A digital pen aggregates and converts written analogue data on paper to digital data, and combined with a diagnostics assessment platform, enables an AI algorithm to recommend an individualized study plans.

aDNA

edit

Anoto's dot pattern, when used with aDNA, allows for the unique and unobtrusive marking of physical objects. This then enables easy identification of individual objects using ubiquitous mobile devices such as phones and tablets. aDNA is opening up new possibilities for product innovation, marketing insights, and supply-chain control.

C-Pen

edit

Anoto used to develop and sell the C-Pen, a one-line text scanner.

Patents

edit

Anoto holds more than 300 international patents on their technology and some 300 additional patent applications.
