Abstract
A navigation method for a wearer of a see-through head mounted device, the method comprising: •—a wearer visualization parameter providing step (S1), during which at least one wearer visualization parameter is provided, •—a geo-position determining step (S2), during which the geo-position of the wearer along a route is determined, •—a geo-position comparing step during which the geo-position of the wearer determined during the geo-position determining step is compared to stored geo-positions along the route and •—a navigation visual aid function adapting step (S3) during which upon matching of the geo-position of the wearer with one of the stored geo-positions, the navigation visual aid function is adapted based on the wearer vision parameter and the geo-position of the wearer to facilitate the guiding of the wearer.
