Claim 16:
17. An Augmented Reality (AR) based navigation apparatus for a movable body, comprising:
an image sensor attached onto the movable body, and configured to capture an image, and output image data; and
processing circuitry configured to:
detect a position of the movable body via a positional sensing system;
receive and store tidal current information based on the detected position;
calculate an estimated time for the movable body to reach a predetermined position of a tidal current captured on the image displayed on a display screen;
generate display data for displaying a first graphical user interface (GUI) for displaying the tidal current information corresponding to the predetermined position of the tidal current on the display screen;
generate the display data for displaying a second GUI on the display screen for displaying the tidal current information at the detected position of the movable body if the detected position of the movable body coincides with the predetermined position of the tidal current;
superimpose the first and second GUIs on the image; and
display the superimposed image on the display screen, wherein

the first GUI is configured for showing:
a first gauge including the estimated time to reach the predetermined position, a direction and a speed of the tidal current at the estimated time, and
a first triangle-shaped indicator movable around a periphery of the first gauge for indicating a direction of the tidal current with respect to an estimated heading direction of the movable body at the estimated time.
