Conventionally, navigation devices have worked by giving the user visual directions, this one however, is more of an ear-pulling thing that will guide the user by tugging gently at the ears. The wearer will be made aware of the directions through this “ear pulling,” which the manufacturers found to be more efficient and lighter than the conventional hand/arm pseudo pulling force method. The lightweight device could actually find a wide range of applications, even for the visually impaired.
