An artificial intelligence (AI)-powered backpack developed by University of Georgia (UGA) researchers can help vision-impaired wearers navigate their environment.

The tool employs a Luxonis OAK-D spatial 4K camera equipped with an on-chip edge AI processor and Intel's Movidius image processing technology.

The camera is bundled inside a vest or fanny pack, while Intel's OpenVINO toolkit is used for inferencing; the system can operate for up to eight hours via a pocket-sized battery, while the backpack also holds a lightweight computer with a global positioning system unit.

The UGA researchers said the system can detect obstacles and relay the wearer's whereabouts through audio prompts, as well as reading traffic signs and identifying changes in elevation.
