DETERMINING MOTION IN INDOOR SPACE USING PROBABILISTIC REPRESENTATION OF MOTION TRANSITION

A method and a device for determining motion of a device are described. In an example, a plurality of points-of-interest (POIs) are identified in a pedestrian area of an indoor space and, with each POI, a probabilistic representation of motion transition of a device from the POI is associated. The probabilistic representation of motion transition is indicative of a probability distribution of likely directions of motion that the device can exhibit from the POI. Further, a map of the indoor space is generated based on the association and the map is usable for ascertaining motion of the device in the indoor space.
