Patent CN107139606B
Updated October 29, 2026Multifunctional Pen with Handwriting Sensing, Vibration Feedback and Remote Display
Practicing handwriting or taking notes often means checking a separate copybook or screen to see if strokes are correct. This multifunctional pen puts the feedback directly in hand. Sensors at the pen core track the tip position, while a microprocessor decodes the movement and compares it against downloaded font libraries stored in memory. When a stroke is missing or extra, a built-in vibrator shakes to alert the writer immediately. A strip display on the barrel shows the text, and a wireless module sends both the written information and the closest matching font character to a remote data indicator with divided viewing areas showing guide grids. Users can download regular script or running hand fonts via USB before practice, and a microphone allows voice input when a switch button is pressed.

The problem
Students practicing handwriting and adults taking notes face the same difficulty: verifying whether the written strokes match the standard character shape requires looking away at a separate copybook or screen. This breaks concentration and slows down learning. Traditional pens offer no real-time feedback, so errors in stroke order or missing components go unnoticed until someone else reviews the work. Carrying physical copybooks adds bulk, and digital tablets replace the feel of actual pen-on-paper writing entirely.
The solution
This multifunctional pen integrates electronic sensing and feedback directly into a standard pen form factor to solve these issues.
- A pen tip position sensing device inside the barrel tracks the pen core using a miniature webcam, gyroscope, acceleration transducer and pressure sensor.
- The sensor data goes to a microprocessor containing a controller, arithmetic unit and comparator.
- Before writing, users download font libraries (such as regular script or running hand) into the memory through a USB interface.
- During writing, the arithmetic unit decodes the handwriting information, and the comparator selects the closest matching font character from memory.
- If the written text has a missing or extra stroke compared to the reference font, the controller sends a signal to a vibrator, which shakes to prompt the writer.
- A strip display on the barrel surface shows the decoded text, while a wireless communication module sends both the written text and the matched font character to a wireless remote data indicator.
- The remote indicator features a screen of about 5 cun or more, divided into two or more square viewing areas with implied grid patterns, showing the user’s writing and the reference character side by side.
- A microphone and switch button allow the writer to press the button and read out the character’s pronunciation, sending the voice signal to the microprocessor for decoding.

Who it is for
- Educational stationery brands looking to add an electronic handwriting-practice tool to their school supply catalog, giving students immediate physical feedback without needing a tablet.
- EdTech hardware developers building connected classroom tools who need a pen that pairs wirelessly with a larger remote display for teacher monitoring or group practice.
- Office supply wholesalers serving corporate buyers who want a note-taking instrument that digitizes meeting notes locally on the pen and transfers them via USB or wireless connection.
- Promotional product distributors sourcing unique electronic gifts for schools or training centers, where the pen’s dual display and voice input stand out from standard styluses.

Applications
Classroom handwriting practice
Students use the pen to trace characters while the sensors track their strokes. The vibrator alerts them instantly if they skip a line or add an extra one, allowing self-correction without waiting for a teacher to check their paper.
Calligraphy training clubs
Calligraphy students download specific font styles like running hand into the memory before a session. The remote data indicator sits on the desk, displaying the student’s live writing next to the master character in the grid-patterned viewing areas for direct comparison.
Corporate meeting notes
Professionals write notes during meetings using the pen’s standard writing function. Afterward, they connect the USB interface to transfer the digitized text stored in the memory to a computer, keeping physical notes and digital records aligned.
Language learning at home
Learners studying new characters press the switch button and speak into the microphone while writing. The microprocessor processes the voice signal alongside the handwriting data, combining audio pronunciation practice with stroke-order verification.
Where it is less suitable
- Standard everyday writing - Users who only need basic ink on paper will find the electronic compartment and charging requirements unnecessary.
- Wet or outdoor environments - The USB interface, microphone and exposed display surfaces require protection from moisture that standard sealed pens handle easily.
Frequently asked questions
What sensors are inside the pen?
The patent describes a pen tip position sensing device made of four components at the end of the pen core: a miniature webcam pointing toward the tip, a gyroscope, an acceleration transducer and a pressure sensor. Together they track the pen’s movement and pressure during writing.
How does the vibration feedback work?
When writing, the microprocessor decodes the sensor data and compares the strokes against a downloaded font library. If the comparator finds that a stroke is missing or extra compared to the reference character, the controller sends a signal to the vibrator inside the barrel, causing it to shake and alert the writer.
What is the wireless remote data indicator?
It is a separate device paired with the pen via a wireless communication module. According to the patent, it has a display screen sized at about 5 cun or more, divided into two or more square viewing areas with implied grid patterns. It shows the user’s written text and the closest matching font character side by side.
Does the pen support voice input?
Yes. The patent lists a microphone and a switch button inside the electronic compartment. When the user presses the switch button and speaks, the microphone captures the voice signal and sends it to the microprocessor for decoding.
How is the pen powered?
A power supply inside the barrel includes a rechargeable battery and a power supervisor that distributes electricity to the electronic components. The USB interface connects to the power supply for charging and to the memory for downloading font libraries.
Can the font libraries be changed?
The memory stores font libraries such as regular script or running hand. These are downloaded into the pen through the USB interface before practice, allowing different character styles to be loaded as needed.
Is the display on the pen itself large?
The patent describes the display on the barrel surface as having a strip shape. Exact dimensions are set in design and confirmed on prototypes to ensure the pen remains comfortable to hold.
Can this design be made and sold in the US?
The patent was filed only in China and is lapsed due to non-payment of annual fees, so it does not restrict the design in the US or in China. Electronic writing instruments may be covered by other US patents - see Patent & Production - so we recommend a freedom-to-operate check before volume production.
