The Bat is a wearable, indoor navigation assistant for the visually impaired. It is designed to be discreet when compared to other aids, such as a cane or service animal, which can give the user more independence. The user can use this device to freely roam around the interior of a building or enable the navigation system to be guided, with verbal instruction, to an exit.
