Across the globe, artificial intelligence (AI) technologies are increasingly shaping the lives of visually impaired individuals, empowering them with new tools for independence and engagement. Two notable innovations poised to revolutionize daily routines include the "Be My AI" application and the WeWalk cane, both of which demonstrate how digital advancements can bridge accessibility gaps.
Louise Plunkett, who suffers from Stargardt disease — causing progressive vision loss — utilizes apps like "Be My AI" which leverages ChatGPT technology to generate detailed descriptions of images. This application allows users to identify common objects, read product labels, and navigate their environment more easily. "It's incredibly convenient," Plunkett notes, though she acknowledges the app’s propensity for overly complex descriptions.
Initially, "Be My AI" relied on human volunteers providing descriptions via video calls. Recently, its features have evolved, embracing AI capabilities for tasks like analyzing images sent through messaging platforms. The future vision for this tool includes real-time video assistance, potentially allowing users to receive live descriptions of their surroundings without delay.
On the hardware front, the WeWalk cane stands out as another significant development. This AI-powered device is not just any ordinary white cane; it incorporates smart technology capable of obstacle detection, navigation assistance, and even public transport updates, all of which can be accessed via simple voice commands. Advocates from organizations like the Royal National Institute of Blind People highlight the transformative potential of AI technologies like this, emphasizing their ability to significantly ease day-to-day challenges faced by those with vision impairments.
Meanwhile, Dot Inc., collaborating with Microsoft and Hanyang University, has recently announced the upcoming launch of DotVista—a game-changing AI application developed for Windows 11. DotVista will render images as tactile experiences on the Dot Pad, enabling visually impaired users to explore shapes, such as animals and well-known monuments, through touch.
Officially set to debut in the second quarter of 2025, DotVista will feature educational functions like the Accessible Zoo, which serves to familiarize students with various animal shapes, and the Fruits Classification function, which assists users—empowering them not only with navigational aids but also with tools necessary for quality control and other job tasks.
The Dot Pad itself is noteworthy; it converts text and images to braille, enabling users to access rich information through touch. Dot Vista's use of on-device AI models radically transforms routine experiences, opening up new possibilities for the visually impaired to engage with the world around them effectively.
Professor Yongjae Yoo, whose scholarship at Hanyang University nurtured this project, expresses optimism about the broader impact of such innovations on the lives of visually impaired individuals globally. He believes, "Korea's innovative startup technology will enrich the lives of visually impaired adults worldwide." Indeed, Dot Inc. aims to create far-reaching accessibility solutions for over 280 million visually impaired people worldwide.
Not to be outdone, the Pittsburgh Robotics Discovery Day showcased numerous startups working on technologies to aid the visually impaired. At this year's event, ForSight Assistive Devices presented the Pathfinder, which uses 3D sensing technology to create vibrations alerting users to nearby obstacles. Co-founder Lyman Petrosky, inspired by the 1968 Star Trek episode featuring a blind character using sensory clothing, remarked, "It's been a dream for 50 years and now technology is making it possible." Their prototype aims to hit the market soon, signifying great strides toward practical navigation aids for the visually impaired.
Discovery Day also featured Agility Robotics, which introduced Digit, their humanoid robot capable of safely lifting and moving packages. Initially utilized away from human workers, improvements on Digit due for release will enable closer collaboration with humans.
Another notable display was from Hellbender, which has been developing multi-camera devices capable of mimicking human depth perception. These could significantly benefit tasks requiring visual analysis across various fields, including robotics and autonomous driving.
Such events highlight the multitude of options becoming available; as AI continues to advance, the accessibility technologies for visually impaired individuals evolve as well, creating opportunities for greater independence and participation. Each innovation, from tactile displays to AI-driven navigation aids, emphasizes the capacity of technology to uplift and empower individuals facing challenges, showing there’s light at the end of the tunnel — and technology is leading the way.
