Animals use echolocation for hunting and navigation, but visually impaired humans also employ echolocation as part of their orienting repertoire while navigating the world. There are a few rare individuals who can echolocate very well without assistance. However, researchers at Boston University have developed a prototype device that can enhance auditory cues while navigating an environment.
