Real-time descriptions of surroundings for people | Newswise
The quick and clear mental image of the real world helps people who are blind or have low vision focus on other tasks, or just enjoy the things around them A world of color and texture could soon become more accessible to people who are blind or have low vision through new software that narrates what a camera records. The tool, called WorldScribe, was designed by University of Michigan researchers and will be presented at the ACM Symposium on User Interface Software and Technology in Pittsburgh next week. The tool uses generative AI (GenAI) language models to interpret the camera images and produce text and audio descriptions in real time to help users become aware of their surroundings more quickly. It can adjust the level of detail based on the user's commands or the length of time that an object is in the camera frame, and the volume automatically adapts to noisy environments like crowded rooms, busy streets and loud music. The tool will be demoed at 6 pm EST Oct, 14, and a study of the tool -- which organizers have identified as one of the best at the conference -- will be presented at 3:15 pm EST Oct. 16. "For us blind people, this could really revolutionize the ways in which we work with the world in everyday life," said Sam Rau, who was born blind and participated in the WorldScribe trial study. "I don't have any concept of sight, but when I tried the tool, I got a picture of the real world, and I got excited by all the color and texture that I wouldn't have any access to otherwise," Rau said. "As a blind person, we're sort of filling in the picture of what's going on around us piece by piece, and it can take a lot of mental effort to create a bigger picture. But this tool can help us have the information right away, and in my opinion, helps us to just focus on being human rather than figuring out what's going on. I don't know if I can even impart in words what a huge miracle that truly is for us." During the trial study, Rau donned a headset equipped with a smartphone and walked around the research lab. The phone camera wirelessly transferred the images to a server, which almost instantly generated text and audio descriptions of objects in the camera frame: a laptop on a desk, a pile of papers, a TV and paintings mounted on the wall nearby. The descriptions constantly changed to match whatever was in view of the camera, prioritizing objects that were closest to Rau. A brief glance at a desk produced a simple one-word description, but a longer inspection yielded information about the folders and papers arranged on top. The tool can adjust the level of detail in its descriptions by switching between three different AI language models. The YOLO World model quickly generates very simple descriptions of objects that briefly appear in the camera frame. Detailed descriptions of objects that remain in frame for a longer period of time are handled by GPT-4, the model behind ChatGPT. Another model, Moondream, provides an intermediate level of detail. "Many of the existing assistive technologies that leverage AI focus on specific tasks or require some sort of turn-by-turn interaction. For example, you take a picture, then get some result," said Anhong Guo, an assistant professor of computer science and engineering and a corresponding author of the study. "Providing rich and detailed descriptions for a live experience is a grand challenge for accessibility tools," Guo said. "We saw an opportunity to use the increasingly capable AI models to create automated and adaptive descriptions in real-time." Because it relies on GenAI, WorldScribe can also respond to user-provided tasks or queries, such as prioritizing descriptions of any objects that the user asked the tool to find. Some study participants noted that the tool had trouble detecting certain objects, such as an eyedropper bottle, however. Rau says the tool is still a bit clunky for everyday use in its current state, but says he would use it everyday if it could be integrated into smart glasses or another wearable device. The researchers have applied for patent protection with the assistance of U-M Innovation Partnerships and are seeking partners to help refine the technology and bring it to market. The research was funded by U-M.

AI-powered software narrates surroundings for visually impaired in real time
A world of color and texture could soon become more accessible to people who are blind or have low vision, via new software that narrates what a camera records. The tool, called WorldScribe, was designed by University of Michigan researchers and will be presented at the 2024 ACM Symposium on User Interface Software and Technology in Pittsburgh. The study is titled "WorldScribe: Towards Context-Aware Live Visual Descriptions" and appears on the arXiv preprint server. The tool uses generative AI (GenAI) language models to interpret the camera images and produce text and audio descriptions in real time to help users become aware of their surroundings more quickly. It can adjust the level of detail based on the user's commands or the length of time that an object is in the camera frame, and the volume automatically adapts to noisy environments like crowded rooms, busy streets and loud music.

University of Michigan researchers have developed WorldScribe, an AI-powered software that provides real-time audio descriptions of surroundings for people who are blind or have low vision, potentially revolutionizing their daily experiences.
Researchers at the University of Michigan have developed a groundbreaking AI-powered software called WorldScribe, designed to provide real-time audio descriptions of surroundings for people who are blind or have low vision. This innovative tool, set to be presented at the 2024 ACM Symposium on User Interface Software and Technology in Pittsburgh, has the potential to revolutionize how visually impaired individuals interact with the world around them 12.
WorldScribe utilizes generative AI (GenAI) language models to interpret camera images and produce instant text and audio descriptions. The system comprises:
The tool adapts to user needs by:
The software employs three different AI language models to provide varying levels of detail:
Sam Rau, a blind participant in the WorldScribe trial study, expressed excitement about the tool's potential:
"I got a picture of the real world, and I got excited by all the color and texture that I wouldn't have any access to otherwise. This tool can help us have the information right away, and in my opinion, helps us to just focus on being human rather than figuring out what's going on." 1
The quick and clear mental image provided by WorldScribe could significantly reduce the mental effort required for visually impaired individuals to understand their surroundings, allowing them to focus on other tasks or simply enjoy their environment 12.
While promising, WorldScribe still faces some challenges:
Researchers are seeking partners to refine the technology and bring it to market, with the goal of integrating it into more user-friendly wearable devices like smart glasses 12.
Dr. Anhong Guo, an assistant professor involved in the project, highlighted the significance of WorldScribe in the field of assistive technology:
"Providing rich and detailed descriptions for a live experience is a grand challenge for accessibility tools. We saw an opportunity to use the increasingly capable AI models to create automated and adaptive descriptions in real-time." 12
This advancement represents a shift from task-specific AI assistive technologies to more comprehensive, real-time support systems for visually impaired individuals, potentially opening up new possibilities for independence and engagement with the world around them.
