摘要：
A method for providing directions to a blind user of a smart device is described. The method includes detecting, by at least two sensors and in response to a selection of a find mode of the smart device, image data corresponding to a surrounding environment of the smart device and positioning data corresponding to a positioning of the smart device. The method also includes receiving, by an input device, the desired object or the desired location. The method also includes determining, by a processor, the initial location of the smart device based on the image data, the positioning data and map data stored in a memory of the smart device. The method also includes providing, by the output device, the directions to the desired object based on the initial location of the smart device and the map data.
