Innovative Dot Pad from South Korea Makes Images Touchable for the Visually Impaired

While braille is widely used by the visually impaired, accessibility to images on the web and smart devices has been difficult.

Dot Inc. continues to create innovative tech to improve the lives of the blind and visually impaired worldwide with the Dot Pad, whose tactile display technology makes images touchable.

While people sometimes rely on visuals to understand complex topics, the 285 million blind and visually impaired people worldwide are unable to do so. Tactile books are sometimes scarce, expensive, and impractical and audio descriptions often fail because sometimes words simply aren’t enough to explain complex information.

With these difficulties in mind Dot Inc. working with the creative direction of Serviceplan Innovation, has launched the Dot Pad, a potential game-changer in accessibility tech.

 
 

Dot Pad is a tactile graphics display device for the visually impaired. It can display any visual content from any source because the innovative Dot Image Processing technology uses Al to analyze and understand visual input and present it accurately on Dot Pad’s tactile display of 2,400 dots.

Thanks to Dot’s collaboration with Apple, Dot Pad integrates seamlessly with iOS and iPad OS, thereby giving users access to the 2.2 million apps on the App Store, right out of the box says the brand. Dot Pad also reduces dependence on tactile textbooks and audio descriptions for graphical content.

“In the 21st century, it didn’t make sense that visually impaired people cannot access graphical information in a digital way,” said Dot Incorporation co-founder Ki Kwang Sung, who co-founded the company with Eric Ju Yoon Kim.

 
 

“There are a lot of innovations out there in every industry, including education, jobs and social network services… the requirement of graphical information is getting higher, which means visually impaired people are getting cut off. Even in the pandemic situation, remote work and education was mandatory… but they didn’t have any solution to do that.”

Hardware and software innovation in sync

Until now, the development of functional tactile graphics devices was hindered by both hardware and software. Conventional tactile devices use piezoelectricity to power their actuators, making them bulky and expensive.

“Dynamic tactile graphics is a completely new experience for the visually impaired, and a huge opportunity for everyone, from content creators to brands and businesses.”

Additionally, the translation of visual content into something tactile is complex, says Dot Inc. Simple vectorization or edge detection algorithms aren’t capable of producing tactile graphics that are suitable for blind users. It requires computational intelligence to understand what’s in an image and decide what’s important to the audience.

Dot Pad solves these problems with a combination of innovative hardware and software.

Dot Actuator

At the core of the Dot Pad sits the third generation of the innovative Dot actuator technology. While conventional tactile devices use piezoelectricity to power their actuators, Dot Pad uniquely relies on electromagnetism, which reduces size, weight, power consumption and price by more than ten times.

This dramatically increases usability and makes the Dot Pad affordable for the majority of blind and visually impaired users.

While the Dot actuator technology is protected by 30 patents, it’s licensed to other manufacturers to give as many people as possible the chance to benefit from it.

Dot Image Processor

It requires computational intelligence to understand what’s in an image and decide what’s important to the audience. To create comprehensible tactile content, Dot Pad relies on the innovative Dot Image Processor. It’s an AI that was trained with millions of existing visual and tactile graphics, to be able to analyze, understand and segment visual content, and translate it to tactile graphics most suitable for blind users.

Supported by big tech, universities, and governments

Launched in early 2022, Dot Pad has earned interest from the media as well as public and private institutions worldwide, with millions of dollars in orders the company said in a release.

The Dot Pad technology is even being shared with competitors to give visually impaired people all around the world access to tactile graphics. Dot Pad technology is permanently installed in public kiosks in Busan, South Korea.

“In the 21st century, it didn’t make sense that visually impaired people cannot access graphical information in a digital way.”

Dot Inc. is partnering with many educational and governmental institutions like UC Berkley, Carnegie Mellon University, McGill University, Columbia University, Busan Public Transportation, and the National Museum of Korea among others.

“When we started to partner with Dot Inc. in 2015, the idea of Dot Pad was a wild dream,” said Alexander Schill, Chief Creative Officer, Serviceplan Group .

“For seven years, we worked together to develop innovative devices and software that makes text accessible to the visually impaired. But the goal was always to go beyond. With Dot Pad, we’re now literally entering a new dimension. Dynamic tactile graphics is a completely new experience for the visually impaired, and a huge opportunity for everyone, from content creators to brands and businesses. My mind bursts when I think about what can be created with Dot Pad. It’s the end of one journey, and the beginning of a new one.”
