Method and device for indoor positioning
First Claim
1. Method for positioning a user inside a building, wherein the user has a user carried device and the user carried device is provided with a direction sensor and a movement sensor, the method comprising the steps of;
- providing the user carried device with a vector map of the building, wherein the vector map comprises vectors and nodes representing possible movement paths for the user in the building,determining at the user carried device a starting point in the vector map representing a first position of the user,receiving movement information at the user carried device from the movement sensor regarding movement of the user in the building,receiving direction information at the user carried device from the direction sensor regarding the direction of the movement of the user, andestimating at the user carried device a new position of the user based on the vector map, the movement information and the direction information.

Abstract
The present invention relates to a method for positioning a user inside a building, wherein the user has a user carried device (100) and the user carried device (100) is provided with a direction sensor (110) and a movement sensor (110). The method comprises the steps of providing the user carried device with a vector map (220) of the building, wherein the vector map (220) comprises vectors and nodes representing possible movement paths for the user in the building; determining a starting point in the vector map representing a first position of the user; receiving movement information from the movement sensor (110) regarding movement of the user in the building; receiving direction information from the direction sensor (110) regarding the direction of the movement of the user; and estimating a new position of the user based on the vector map, the movement information and the direction information.

8. A user carried device for positioning a user inside a building, the user carried device comprising a direction sensor and a movement sensor, wherein the user carried device is provided with a vector map comprising vectors and nodes representing possible movement paths for the user in the building,
wherein the movement sensor is adapted to provide movement information regarding movement of the user in the building and the direction sensor is adapted to provide direction information regarding the direction of the movement of the user, and wherein the user carried device comprises a calculation unit that is adapted to, based on a starting point in the vector map representing a first position of the user, estimate a new position of the user based on the vector map representing possible movement paths for the user in the building, the direction information and the movement information.
