fiber-optic pen may help scientists understand dyslexia - writing pad for pc
A new fiber-
Optical pens may help to reveal the unique brain patterns of patients with dyslexia, such as dyslexia.
Engineers at the University of Washington made the device by hollowing out ballpoint pens and sticking two fiber optic fibers to the center.
One fiber glows on a custom writing board with a continuous color gradient, while the second fiber transmits the light back to the color sensor in the nearby computer.
By identifying the change of color when the pen moves on the keyboard, the computer records the path of the pen in a real waytime movie.
"We need an absolute measure of where they are," said Frederick Ritz, an engineer involved in the project . ".
"So we can't just use the board to determine the relative movement.
We really need to know where they put the pen on the mat.
"The team designed a pen that can be used in the brain --
Scanning a functional magnetic resonance imaging (fMRI) machine that allows a person to track brain patterns when writing.
Functional magnetic resonance imaging (fMRI) reveals blood flow, a measure of brain activity.
By analyzing the brain scan next to the computer
The team wants to identify brain regions associated with specific writing disorders symptoms and generate pen path records.
Pens may also help to examine brain patterns in Sports patients
Damage to diseases such as Parkinson's disease or multiple hardening.
Other similar devices already exist, including the fMRI-

The new pen is the simplest and cheapest tablet, priced at around $100.

Life Science, Reitz told.
"It took a little bit of time for the software to figure it out, but it's now public --
So the hurdles are hurdles.
"The team is trying to speed up their fibers --
And plan to test the improved model in the next few months.
The study was presented in detail in April in the journal Sensors, and was published in June 18 at the annual meeting of the human brain mapping organization in Seattle.

In today’s fast-moving business environment, traditional posters and static displays are no longer enough to capture customer attention. Businesses are increasingly turning to indoor digital signage displays to improve communication, promote products, and create more engaging customer experiences.
From retail stores and shopping malls to corporate offices, restaurants, schools, hotels, and healthcare facilities, indoor digital signage has become an essential solution for delivering dynamic content in real time.
At ITATOUCH, we provide high-brightness indoor digital signage displays with customizable hardware and software options, helping partners and businesses create tailored digital communication solutions.
Introduction: Why Traditional Interactive Displays Are No Longer Enough
As smart classrooms and hybrid workplaces continue to evolve, many organizations are facing a common challenge: traditional interactive displays can no longer meet the growing demand for visual clarity, intelligent collaboration, and long-term performance.
In education, teachers need smoother writing experiences, better visibility in bright classrooms, and seamless hybrid teaching tools. In corporate environments, businesses require professional video conferencing, high-quality presentations, and reliable systems for efficient collaboration.
This is where the next generation of premium QLED interactive flat panels makes a significant difference.
With innovations such as QLED Local Dimming technology, 4K UHD display, AI camera systems, optical bonding, and flagship-level processing power, modern interactive flat panels are becoming more than just displays—they are transforming into complete smart collaboration hubs.
In today’s competitive retail environment, attracting customers starts before they even enter your store. A high brightness window display is one of the most effective tools for increasing foot traffic, promoting products, and enhancing brand visibility in shopping malls, retail stores, restaurants, beauty salons, banks, and commercial spaces.
Unlike standard screens that appear dim under strong ambient light, ultra high brightness window displays are specifically designed for storefront applications, delivering vivid visuals and clear advertising content even in direct sunlight.
In today’s fast-evolving education and corporate environments, traditional lecterns are no longer enough. Schools, universities, and training centers are upgrading to smart digital podiums to create more engaging, efficient, and technology-driven learning spaces.
A Smart Digital Podium is more than just a lectern — it is an all-in-one interactive teaching solution that integrates display, control system, audio, connectivity, and multimedia management into one streamlined platform.
As education and corporate environments continue to evolve, the demand for smarter, more flexible display solutions is growing rapidly. Traditional blackboards and whiteboards still play an important role in teaching and meetings, but they no longer fully meet the needs of modern classrooms and collaborative spaces. This is where the Interactive Blackboard comes in — a next-generation solution that seamlessly integrates interactive flat panel technology with traditional writing boards, creating a powerful and intuitive experience for users.
Designed for flexibility, customization, and real-world usage, the interactive blackboard bridges the gap between conventional teaching habits and advanced digital tools.
ITA TOUCH operates a 20,000+ sqm smart manufacturing facility in Shenzhen, equipped with dedicated production lines for interactive displays and digital signage.
We welcome factory visits, online inspections, and OEM audits.
