1. A tactile feedback navigation system comprising:

  • a first sensor operable to detect the global orientation of the user to produce a first output, said first sensor being an on-board sensor portable by a user, or an off-board sensor positioned distant from the user;

    a sensor detector operable to detect geographic co-ordinate position (in terms of latitude and longitude) of the user to produce a second output, said geographic co-ordinate position being provided to indicate latitude and longitude, said sensor detector being an on-board sensor portable by a user, or an off-board sensor positioned distant from, the user;

    a second sensor operable to detect 3-directional accelerations of the user to produce a third output, said second sensor being an on-board sensor portable by a user, or an off-board sensor positioned distant from the user, and any combination of the first output, the second output and the third output individually or collectively being sensor outputs;

    a plurality of tactile actuators operable to provide directional information to a landmark and its inherent coordinate system, placed in the cardinal locations (North (N.), South (S.), West (W.), and East (E.)) aligned on a body part upon which a scale system is superimposed that repeats itself in degree ordinates; and

    each cardinal location is exactly separated by 90 degrees;

    at least one tactile actuator operable to provide distance information to a landmark;

    a wireless communication apparatus operable to communicate to an internet network via an external device;

    an integrated power management and portable power source; and

    a controller in communication with the sensors operable to receive and process at least one on-board sensor output and at least one off-board sensor output into an optimal accurate estimate of global position in terms of latitude and longitude and the position, and size of objects and terrain in the immediate environment, wherein the controller is operable to activate adjacent actuators in succession so as to indicate an intermediate point between two actuators by interpolation.
