Abstract: A method of navigating a visually impaired user, a navigation system and a guiding robot used in the system. The method includes the steps of: receiving a plurality of location referencing signals from a plurality of signal sources; processing the location referencing signals to determine a current location of the user in a predetermined area; planning an optimal path for the user to travel from the current location to a destination location; providing guiding information associated with the optimal path to the user; obtaining a travel instruction from the user to travel along the optimal path; and moving a guiding robot according to the travel instruction provided by the user along the optimal path until the next travel instruction is required to further move the guiding robot.
