Dot matrix digital pen
Writing instrument that transmits information out via Bluetooth or USB cable.
The dot matrix digital pen is a kind of invisible dot matrix pattern printed on ordinary paper. The high-speed camera at the front of the digital pen captures the movement trajectory of the pen tip at any time. At the same time, the pressure sensor transmits the pressure data back to the data processor. A new type of writing instrument that transfers out via Bluetooth or USB cable.
Product description
Different from ordinary paper and pens, this information includes paper type, source, page number, position, handwriting coordinates, motion trajectory, nib pressure, stroke order, pen running time, pen running speed and other information. The handwriting recording process is synchronized with the writing process.
When writing, the dot matrix digital pen stores the words or pictures written on the paper in the computer in the form of bitmaps to form a document, which can also be synchronously displayed by projection if necessary.

working principle
When the pen tip is pressed, the pressure sensor is triggered, and the built-in high-speed camera is activated to take pictures of the dot matrix passed by the pen tip at a speed of 100 frames per second, and the dot matrix coordinates, handwriting sequence, pressure data, movement speed and other information Passed to the built-in processor, and finally outputted through the Bluetooth or USB communication unit. With some pen types, data can be temporarily stored in memory and output when necessary.
Application broadcast
The technology of the dot matrix digital pen relies on the digital optical dot matrix technology. The software products derived from this technology are DoTnote, Symphony and Tnote, and these three software products must use the dot matrix digital pen as the core hardware facility.
DoTnote
While the dot matrix digital pen writes on printed materials such as notebooks and textbooks, the writing results are simultaneously saved to computers, tablets and smartphones, so as to achieve the goal of digitally storing, sharing and managing notes. Realize face-to-face writing, authentic reproduction, real-time synchronization, offline caching, annotation recording, text recognition, note playback, platform crossing and other functions.
The main applications of DoTnote are: personal note management, teaching electronic writing on the blackboard, student homework management and so on.
Symphony
When multiple people write on the paper with the dot matrix digital pen, their writing results will be synchronized to the computer, and the teacher can grasp the writing content of each person on the paper in real time.
Casual writing on paper is more likely to inspire inspiration and creativity;
Break through the existing communication mode and realize all-round information sharing;
Reduce the time communicators spend walking back and forth between their seats and the whiteboard;
All written communication content is automatically saved for easy review and review;
Wireless transmission mode, timely and efficient information exchange.
The main applications of Symphony are: interactive teaching classroom, interactive communication platform and so on.
Tnote
In the remote Internet environment, it breaks through the interactive mode based on video, voice and keyboard, and provides an interactive platform for writing on paper through a dot matrix digital pen.
Not limited by time and space
Share a whiteboard to write at will
Pick up a pen and paper to answer the questions
Can view written content
Convenient and quick realization of teaching recording and broadcasting
Anyone can write on the whiteboard
The main applications of Tnote are: distance teaching, distance meeting and so on.
