1. A navigation system, comprising:
- a plurality of spaced apart short range echo-location sensors, at least two sensors in conjunction with each other configured to triangulate upon objects within a user'"'"'s environment at a single point in time to determine information relating to the objects within the user'"'"'s environment and information relating to avoiding objects within the user'"'"'s environment;
at least one long range navigation sensor that determines geographical information relating to the user'"'"'s geographic location;
wherein the information relating to the objects within the user'"'"'s environment, the information relating to avoiding objects within the user'"'"'s environment, and the geographical information relating to the user'"'"'s geographic location are provided to the user by a wearable transducer.

Abstract
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.
