US Patent 9201143 Assisted guidance navigation

A navigation system helps users navigate through an environment by a plurality of sensors. The sensors include one or both of short and long range sensors that detect objects within the user's environment. Information obtained from the sensors' detection of objects within the user's environment can be used to help the user avoid colliding with objects within the environment and help navigate the user to a destination. The navigation system may provide the user with audible feedback regarding the objects with the user's environment and/or instructions regarding how to avoid colliding with an object and how to navigate to a destination.
