Abstract

A smart necklace includes a body defining at least one cavity and having a neck portion and first and a second side portions. The necklace includes a pair of stereo cameras that is configured to detect image data including depth information corresponding to a surrounding environment of the smart necklace. The necklace further includes a positioning sensor configured to detect positioning data corresponding to a positioning of the smart necklace. The necklace includes a non-transitory memory positioned in the at least one cavity and configured to store map data and object data. The smart necklace also includes a processor positioned in the at least one cavity, coupled to the pair of stereo cameras, the positioning sensor and the non-transitory memory. The processor is configured to determine output data based on the image data, the positioning data, the map data and the object data.
