A method for a user to navigate in a surrounding world captured by one or more image sensors and displayed to the user in an image display area of a display device which in use is in front of the user's head and follows the movements of his head. When the user's head is directed in an area which the user can easily reach by turning his head, the display is controlled by his head direction. When the head direction reaches the edge of what the user can reach by turning his head, use is instead made of controlling by gaze direction of that displayed, in which case the point of the surrounding world pointed out by the gaze direction is continuously placed in a predetermined area of the image. The change occurs either automatically by the user's gaze direction being at the edge of the image display area or by a command, for instance with the user's voice or a motion of his hand. |
