Abstract:
A rule set is used to generate an indoor map of a building from partial map data. In one embodiment, the partial map data is based at least in part on crowd sourced trajectory data. In one embodiment, a probabilistic rule set describes relationships in space usage of the indoor building. Hypothesis testing is performed. A most likely complete layout is determined, based on the partial coverage data and the rule set, which preserves the partial map data.
Abstract:
A method, mobile device, and non-transitory computer readable medium for transmitting information. The method includes determining, by a mobile device, a distance between the mobile device and another device in response to a request for the mobile device to transmit the information. The method also includes determining, by the mobile device, whether the distance between the mobile device and the other device is within a threshold distance. Additionally, the method includes transmitting, by the mobile device, the information to the other device after determining that the distance between the mobile device and the other device is within the threshold distance.

Abstract:
Mapping through crowdsourcing includes determining, using a processor, segments for a plurality of trajectories, wherein each trajectory includes radio frequency (RF) data from a communication device, determining, using the processor, RF features for the segments, and forming, using the processor, clusters of the segments according to the RF features. One or more routes of a map are generated from the clusters using the processor.
Abstract:
In one aspect, a method for determining a location of a landmark using a map is described. Trajectory data is obtained indicating movement of a device at an area. The trajectory data indicates a landmark. A map is obtained of the area. At least a portion of the trajectory data is compared and/or matched with at least a portion of the map. Based on the matching, a location of the landmark is determined in the map. Various implementations involve system, devices and software relating to the above method.
