OMO

Smart devices for the visually impaired

By recognizing amplitude feedback of different frequencies and voice prompts, "OMO" provides guidance for the visually impaired through ultrasonic ranging technology. The visually impaired record the bad experiences encountered during a trip through the "OMO" and upload this feedback. These data form a visual map of the city through IoT technology. After the city managers collect this feedback, they will add or improve the accessibility facilities over time to create a better travel environment for the visually impaired.
