Researchers from the Johns Hopkins Utilized Physics Laboratory and Whiting Faculty of Engineering have developed a navigation system for blind and visually impaired customers that faucets synthetic intelligence (AI) to create a semantic map of their atmosphere — instructions from that are fed again utilizing a vibrating headband, voice prompts, and spatial sounds.
“Conventional navigation techniques for the visually impaired usually depend on primary sensor-based mapping, which may solely distinguish between occupied and unoccupied areas,” explains lead researcher Nicolas Norena Acosta of the staff’s work. “The brand new semantic mapping strategy, nevertheless, supplies a a lot richer understanding of the atmosphere, enabling high-level human-computer interactions.”
The staff’s moveable navigation system makes use of a mix of depth-sensing and visible-light cameras fed right into a machine studying system, which may flip the info right into a “semantic map” of the consumer’s environment. For the partially sighted, that is then fed again as a simplified view of the world with solely probably the most essential data highlighted; for the absolutely blind, a vibrating headband mixed with spoken-word and spatial sound cues performs the identical process.

“The problem was making a system that would synchronize and course of a number of varieties of sensory knowledge in actual time,” Norena Acosta notes. “Precisely integrating the visible, haptic and auditory suggestions required subtle algorithms and sturdy computing energy, in addition to superior AI methods.”
“The potential influence of this work on affected person populations is substantial,” provides principal investigator Seth Billings of the staff’s work. “This might result in higher social inclusion and participation in every day actions, in the end enhancing the general high quality of life for blind and visually impaired people.”
The staff introduced its work on the SPIE Protection + Business Sensing 2024 convention earlier this yr; a medical trial is at present underway, with outcomes anticipated this summer time.
