Confirmation is obtained from the user that the user's gaze is directed to a specified landmark in sight of the user and azimuth is computed between the user location and the landmark location extracted from the computerized map. Vocal prompts are provided and ancillary visual prompts are projected on the display to navigate the pedestrian. In a system, the user wears a head-mounted device containing the IMU and display and carries a GPS unit and a portable computing device coupled to the device and GPS unit and programmed to carry out the method.",
