In addition to enriched the guidance service, there could be another perspective, which is activated
when users choose which direction that they want to follow in instruction list view and then pointing the
camera of the smartphone to the ground. A compass-based arrow could be shown in this view. According
to the device’s orientation it always points to the user direction waypoint. Show basic description of this
waypoint, as well as the distance of it, so user is able to get the most important information to reach the
next waypoint with just a quick look.
