Abstract
A navigational aid for use primarily by the visually impaired in the form of a virtual walking stick, comprising a location sensor and an inertial measurement unit, which can provide angle-dependent navigation directions to a user, and which can be used to record the three-dimensional locations of new objects of interest for later uploading and integration into a global map set of the region.
