Report Errors
Since the external activities of the visually impaired are still not free, it is urgent to find ways to resolve the inconvenience of movement and to expand the range of external activities. In this paper, we propose an IoT device and a navigation service application that recognizes the situation around the visual impaired and voices it. Ultrasonic sensors in the IoT device detect the presence of objects around them and provide different beeps depending on the location of the object to differentiate the object"s proximity. The surrounding objects in the input image through the camera of the IoT device may be recognized by the object recognition algorithm learned by deep learning. The navigation service application provides a customized UI for the visually impaired using voice recognition, TTS, and large icons. The proposed application finds pedestrian paths to the destination, displays all detailed paths on a map, provides voice guidance, and calculates the total walking time.
