Abstract
Various embodiments of systems and methods for providing navigation assistance are described herein. A navigation assistance request is received for commuting between the start waypoint and the destination waypoint. Based on the received request, the angle-orientation coordinates included in the angle-based navigation instruction are converted to direction-based navigation instructions. Finally, the direction-based navigation instructions are provided to a user. In one embodiment, the direction-based navigation instructions are stored in a directed weighted graph. The directed weighted graph may be used to determine navigation instructions for an intersection point. In one embodiment, crowdsourcing is used to collect the navigation instructions.
