Abstract:
There is provided a solution comprising detecting that a positioning device is within a predetermined control area associated with a building, acquiring a first sequence of magnetic field measurements carried out by the positioning device, wherein the first sequence represents at least one of the magnitude and the direction of Earth's magnetic field; determining that an operational environment of the positioning de-vice has changed between an indoor environment and an outdoor environment when a at least one predetermined criterion with respect to the first sequence is met; and causing actuation of a predetermined software function in or with respect to the positioning device when the operational environment of the positioning device has changed.
Abstract:
A mobile apparatus, a computer program for a mobile apparatus, and a method in a mobile apparatus. A string is obtained. A location associated with the string is obtained. Then, a location-based search for location-dependent data is performed on the basis of the location and one or more independent expressions within the string such that the location-dependent data is relevant within a predetermined distance from the location. Finally, at least a part of the location-dependent data is displayed on a map.
Abstract:
There is provided a database entity for generating a search database, comprising: at least one processor and at least one memory including a computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the database entity at least to: acquire, from each of the plurality of mobile devices, an indication of at least one object; acquire a reference Earth's magnetic field, EMF, fingerprint representing at least one of magnitude and direction of the EMF in a location and/or environment to which the at least one object is related to; associate each object with the corresponding reference EMF fingerprint; and generate a database of associations between the reference EMF fingerprints and the objects.

Abstract:
There is provided an apparatus, wherein the apparatus is caused to acquire a location estimate of a positioning device that is to determine its location inside a building, wherein the location estimate is acquired on the basis of an indoor non-magnetic field based location discovery system; access an indoor Earth's magnetic field, EMF, map of plurality of buildings, wherein the indoor EMF map represents at least one of magnitude and direction of the Earth's magnetic field affected by the local structures of a corresponding building; and select a part of the indoor EMF map on the basis of the location estimate of the positioning device, wherein the selected part of the indoor magnetic field map includes the indoor EMF map for the area in which the positioning device currently is.
Abstract:
A method in a processing apparatus includes: obtaining measurement data generated by one or more information sources; selecting one or more parts of a map; and processing the measurement data with a state estimation algorithm within the confines of the selected one or more parts in order to determine an estimated state of a mobile apparatus.
Abstract:
An initial indoor location inside a building is obtained with indoor positioning for a consumer mobile apparatus. Information relating to a common catalog including products available from a plurality of retail outlets inside the building is transmitted to the consumer mobile apparatus. A purchase order of products selected based on the information relating to the common catalog is received from the consumer mobile apparatus. A subsequent indoor location is obtained with the indoor positioning for the consumer mobile apparatus. If the subsequent indoor location is inside the building, a delivery location of the products inside the building is determined with the consumer mobile apparatus, and a delivery order of the products determining the delivery location and collection instructions for the products from the retail outlets inside the building is transmitted to a courier mobile apparatus.
Abstract:
There is provided an apparatus configured to perform operations comprising: acquiring motion data sets from the plurality of mobile devices; estimating route models of the travelled routes on the basis of the motion data sets; generating EMF fingerprints for the travelled routes by associating the acquired EMF data sets with corresponding points of the route models; and determining the locations of the routes with respect to each other on the basis of at least one of the following: the EMF fingerprints and the route models.
Abstract:
Disclosed is an apparatus caused to acquire information indicating a measured magnetic field vector and information relating to an uncertainty measure of the measured magnetic field vector in at least one known location inside the building, wherein the indicated magnetic field vector represents magnitude and direction of the earth's magnetic field affected by the local structures of the building, and to generate the indoor magnetic field map for at least part of the building on the basis of at least the acquired information and the floor plan.
