A navigation guidance system is provided which provides direction information form a remote server to a mobile user unit for guiding the user to a desired destination. The user unit may be a mobile telephone or PDA or the like. A query is input to the user unit either by text or by voice and is sent to the remote server. The mobile unit preferably includes a GPS receiver or the like so that the current location of the mobile telephone can also be transmitted to the remote server. Based on the information received from the user unit, the server determines the appropriate route guidance information and sends this back to the user unit. In a preferred form of the invention, the remote server continues to monitor the progress of the user unit in following the route guidance information and, where appropriate, sends updated route guidance information.
A navigation guidance system comprising a user unit and a remote navigation control server;
A system according to any preceding claim, wherein said output means comprises a display and wherein said navigation guidance information comprises geographical map data relevant to the user's request, for display on said display.
A system according to any preceding claim, wherein said outputting means comprises a display and wherein said navigation guidance information comprises text data relevant to the user's request, for display on said display.
A system according to any preceding claim, wherein said outputting means comprises a speaker for outputting voice signals, and wherein said navigation guidance information comprises voice signals conveying navigation guidance information relevant to the guidance request.
A system according to any preceding claim, wherein said remote server comprises a database including various geographic data and wherein said determining means is operable to filter said database for geographic data relevant to the received navigation guidance request.
A system according to any preceding claim, wherein said remote server is operable to service navigation guidance requests from a plurality of user units.
A system according to any preceding claim, wherein said user unit comprises a mobile telephone.
A system according to any preceding claim, wherein said user unit comprises position sensing means operable to receive signals from a positioning system and for generating therefrom a position indicating signal indicative of the geographical location of the user unit and wherein said user unit is operable to transmit said position indicating signal to said remote server.
A system according to any preceding claim, wherein said user unit further comprises means for determining the orientation of the user unit, wherein the user unit is operable to transmit this orientation information to the remote server and wherein the remote server is operable to send said navigation guidance information in dependence upon the received orientation information.
A system according to any preceding claim, wherein said user unit comprises a communications terminal which is operable to determine its own current location, and wherein said monitoring means is operable to interrogate said communication system to determine said new current location of the user unit.
A method of providing navigation guidance information from a remote server to a user unit, the method comprising the steps of:
A user unit comprising:
A remote server for use in a navigational guidance system, the remote server comprising:
