For people with visual impairments, reading is not only a way to access information, but also an important path to explore the world, learn, and grow.

However, traditional paper Braille books have long faced challenges such as high production costs, limited content availability, large size, and difficulties in carrying.

A regular book can become several thick volumes after being converted into Braille, increasing both the cost and the difficulty of access.

Finding a more convenient way for visually impaired users to read and explore knowledge has become an important challenge in accessible technology.

Starting from Real Needs: Building a “Digital Library” for Braille Readers

In 2021, while conducting user research, Angelo Li（Li Cheng） discovered the challenges faced by visually impaired people in accessing books.

A regular copy of Journey to the Center of the Earth contains only 142 pages and costs just a few dozen yuan. However, after being converted into Braille, the same book can become three thick volumes and cost several hundred yuan.

This experience inspired Angelo Li（Li Cheng）with an idea:

“Could we create a Braille Kindle, allowing visually impaired users to freely choose what they want to read?”

With this vision , Angelo Li（Li Cheng） and his team began developing a new generation of Braille display technology.

During the early stages of development, the team visited Chongqing Special Education Center and spent time with visually impaired students, attending classes with them and learning about their reading needs and daily challenges.

This experience changed the team’s understanding:

A product should not only work technically — it must truly fit the long-term needs of its users.

9 Iterations and 6 User Testing Rounds: From Prototype to Real User Experience

After completing the first prototype, Angelo Li（Li Cheng）sent the device to a visually impaired couple he knew for real-world testing.

The users shared their feedback:

“The device is convenient, and it provides access to many books. But there are still details that need improvement.”

One of the most important issues was Braille dot spacing.

For a comfortable and accurate tactile reading experience, the distance between Braille dots needs to be controlled within approximately 2.5 mm.

However, the first prototype had a dot spacing of 3 mm.

Although the device could already display Braille, the team realized that achieving a truly comfortable reading experience required further optimization.

Based on user feedback,Angelo Li（Li Cheng）and his team redesigned key structures and continued improving the technology.

After more than a year of development, the product went through:

• 9 major design iterations
  
• 6 rounds of user testing

The team eventually developed a smaller, more stable, and more user-friendly Braille display solution.

One Device, Like a Portable Braille Library

Today, the Wiltrue Future 30-Cell Portable Braille Display has become an important tool connecting visually impaired users with the digital world.

Through refreshable electronic Braille cells, the device converts digital information into tactile output in real time.

Users can connect the device to computers and smartphones and work with mainstream screen readers to access:

• Digital books;
  
• Learning materials;
  
• Workplace documents;
  
• Everyday text information.

For user Li Yong, the device feels like:

“A portable library. It is small, but it contains many books.”

Compared with traditional paper Braille books, where raised dots may become worn and less clear after long-term use, digital Braille provides a more stable and sustainable reading experience.

Making More Knowledge Accessible Through Touch

From discovering the challenges of Braille reading to developing practical accessibility technology, Wiltrue has always focused on one principle:

Technology should begin with real human needs.

Through continuous innovation in Braille displays, smart hardware, and digital content ecosystems, Wiltrue aims to help more books, learning resources, and professional knowledge become accessible to visually impaired users.

The journey from one book to a library is not only about technology — it is about creating more equal opportunities to learn and explore the world.

一本书，到一座图书馆：Wiltrue让盲文阅读拥有更多可能

对于视障人士而言，阅读不仅是获取信息的方式，更是认识世界、学习成长的重要途径。

然而，传统纸质盲文书籍长期面临体积大、制作成本高、携带不便等问题。

一本普通书籍转换为盲文后，往往需要数倍篇幅，甚至从一本书变成多册厚重书籍。这不仅增加了阅读成本，也限制了视障用户获取更多知识的机会。

如何让更多书籍能够以更加便捷的方式被阅读，成为WilTrue持续探索的方向。

从真实需求出发，打造属于视障用户的“数字图书馆”

2021年，在一次调研过程中，郦铖了解到视障群体在阅读方面面临的困难。

一本普通的《地心游记》只有142页，价格几十元；但转换为盲文后，却可能变成厚厚三大本，价格也上涨到数百元。

这让郦铖产生了一个想法：

能不能做一款“盲文Kindle”，让视障用户也能够自由选择想阅读的内容？

带着这个目标，郦铖和团队开始了盲文点显器的研发。

研发初期，团队前往重庆市特殊教育学校进行调研，与视障学生一起学习和交流，深入了解他们在阅读和学习过程中遇到的真实困难。

这段经历让团队意识到：

产品不仅需要实现功能，更需要真正满足用户长期使用中的细节需求。

9次迭代，6次用户测试：从技术原型到真实体验

第一版盲文点显器完成后，郦铖将设备交给自己认识的盲人夫妇进行试用。

用户反馈：

“点显器很方便，里面有很多书籍可以阅读，但还有一些细节需要优化。”

其中，一个关键问题是盲文点位间距。

为了获得更好的触摸阅读体验，盲文两个点之间的距离需要控制在约 2.5mm以内。

而第一版产品的点距为 3mm，虽然能够实现基本阅读，但仍无法达到最佳体验。

根据这些真实反馈，团队决定重新优化产品结构和核心技术。

经过一年多持续研发，产品经历：

• 9次整体迭代
  
• 6次用户测试

最终推出了更加小巧、稳定、易用的新版本盲文点显器。

一台设备，像一座随身携带的盲文图书馆

如今，无界方寸30方盲文点显器（WilTrue Future 30-Cell Portable Braille Display）已经成为帮助视障用户连接数字世界的重要工具。

通过电子盲文点阵动态变化，设备可以将数字内容转换为触觉信息。

用户可以连接电脑、手机，并结合主流读屏软件，实现：

• 电子书阅读；
  
• 学习资料获取；
  
• 工作信息处理；
  
• 日常文字浏览。
  

对于用户李永而言：

“这个点显器很小巧，里面的书也很多，就像一个便携的图书馆。”

相比过去阅读纸质盲文时，长时间触摸导致盲文点逐渐磨损、模糊的问题，数字盲文设备提供了更加稳定和持久的阅读体验。

让更多知识通过指尖被感知

从第一次发现盲文阅读困难，到持续优化数字盲文技术，WilTrue始终坚持从用户真实需求出发。

未来，WilTrue将继续探索盲文显示、智能硬件和数字内容生态的发展，让更多书籍、学习资料和专业知识能够被视障群体平等获取。
