1. Method of determining the motion of a pedestrian, comprising the steps of:
- determining at least one position of at least one identified portion of the pedestrian, projecting said position(s) on at least one plane, and deriving the motion from the position(s) projected on said at least one plane.

Abstract
The motion of a pedestrian is evaluated by determining at least one position of at least one identified portion of the pedestrian, projecting the positions(s) on at least one plane, and deriving the motion from the position(s) projected on the at least one plane. Typically the position(s) are determined in three-dimensions, e.g. of the feet. It is possible to project on two different planes to provide three-dimensional navigation information.

33. Method of determining the motion of a pedestrian, comprising the steps of:
-
determining a relative separation between identified body portions of the pedestrian, and deriving from said relative separation a projection on at least one plane over which said pedestrian evolves or over a plane having a component along a direction over which said pedestrian evolves.
