It is possible to analyze the traffic to identify the orientation of the street and anticipate the turns. If the street structure is very rectangular like the United States or Canada, there is no ambiguity when talking about the next street on the right. If you are navigating with an indication of course and distance as the crow flies, any choice of street right or left will eventually lead to closer and closer to destination.
In hiking, it's the opposite, if you miss a turn, there will be no way to catch up except to retrace his steps. The trails may be ill-defined, you can easily make a half-turn without having the sense of traffic to signal disorientation etc.
The hike is a series of points to reach representing segments of straight lines. We report heading and distance to the next point in relation to the person's body. If the person turns around, the information is updated in the second following. When there are dangers, we indicate where to go safely. All proposed trips are checked for accessibility, security and relevance of the information provided.
To make several kilometers in autonomy in full nature is always a appreciated moment which restores confidence.
Since the first major experimental hike in 2011, GPS hiking in autonomy have become democratized.
We are looking for hikers interested in making their paths accessible to the blind.
