Abstract:
Techniques describe opportunistically capturing and tagging images with wireless information by a mobile device. The tagged image may be transmitted to a remote server, such as a crowdsourcing server, where the location at which the image was captured may be determined using visual features from the image. An association between the location and the wireless measurements may be used in building/maintaining a heatmap. In one embodiment, techniques are described for setting camera parameters for opportunistically capturing images and may include receiving at least one signal associated with at least one signal emitting device, determining information associated with the at least one signal emitting device using the at least one signal, setting at least one camera parameter for a camera coupled to the mobile device based on the information associated with the at least one signal emitting device, and capturing one or more images using the at least one camera parameter.
Abstract:
Systems, apparatus and methods for determining a beacon device are presented. A device selects a beacon device by computing travelling distances between a mobile device and respective locations for a plurality of beacon devices. The selected beacon device may be the beacon device the mobile device would reach first and may consider a course of the mobile device and what type of services are offered and needed from a particular beacon device.
Abstract:
Various methods, apparatuses and articles of manufacture are provided for use by one or more electronic devices to detect and/or respond to certain changes (anomalies) within a wireless signaling environment. For example, a first electronic device may receive a report of a threshold anomaly detected by a monitoring device deployed at a fixed predetermined position within a coverage area of a network service device, and may initiate an investigation by requesting that a second electronic device attempt to monitor certain transmissions of and/or actively communicate with a network service device. In response to a determination based, at least in part, on the investigation that the threshold anomaly represents a threshold change in status within the wireless signaling environment, the first electronic device may transmit a status report regarding the wireless signaling environment to another electronic device.
Abstract:
Methods, systems, computer-readable media, and apparatuses for detection of anomalies within indoor map information are presented. In some embodiments, the method includes receiving a digital map. The method may further include identifying one or more anomalies within the digital map using a software-based anomaly detection tool. The method may also include displaying one or more suggested corrections to a user based on the one or more identified anomalies. The method may additionally include correcting the one or more identified anomalies within the digital map.
Abstract:
Various methods, apparatuses and articles of manufacture are provided which may be implemented in various devices for use in characterizing environments. In an example, a mobile device may, gather a plurality of measurements during a period of time, including one or more first measurements generated by one or more environmental sensors, and one or more second measurement generated by a radio based, at least in part, on one or more wireless signals received by the radio. In response to a determination that the mobile device is to report a travel history corresponding to at least a portion of the period of time, the mobile device may generate a travel log based, at least in part, on at least one first measurement and at least one second measurement, and transmit the travel log to an external device.
Abstract:
Method, device, and computer program product, for augmenting metadata for a mapped location is described. Mapped location trajectory data for each of a plurality of mobile devices is received. Purchase transaction data for the respective mobile device at the mapped location is received from each of the respective mobile devices. The purchase transaction data is correlated with the mapped location trajectory data to determine a purchased product location within the mapped location. The metadata for the mapped location is augmented to include the purchased product location.
Abstract:
An appliance facilitates localization of a station (STA) in a network, for example, a short-range wireless network. An automatic response to a request for a measurement related communication is provided. The appliance can include a radio frequency (RF) interface and a media access control (MAC) section. The MAC section can receive the request and generate the automatic response immediately after a uniform period that is uniform among any such appliance within the network. The appliance performs only the generation of the automatic response, though the response can include additional information such as (x, y) coordinates of the appliance.
Abstract:
Methods and devices are described for providing localized secure navigation in conjunction with near field communication access control systems. In one potential embodiment, a mobile device such as a cell phone may communicate with a door access control point using near field communication to receive location access system information. The mobile device may then authorize download and execution of a local secure navigation module from a location access system using the location access system information for use in receiving location assistance data, based on an authentication level associated with the mobile device. Such location assistance data may be used by the local secure navigation module to provide location assistance when the mobile device is in a secure location. The location of the mobile device may then be tracked using at least the location assistance data and the communication with the door access control point.
Abstract:
Disclosed are systems, methods, and devices for aligning a path of movement of a mobile device with an indoor routing graph. In one particular embodiment, a mobile device may trace a path of movement from a starting point to a point of intersection with a routing graph that defines feasible movement within an area. Responsive to a detecting a point of intersection, a mobile device may estimate a contiguous route from one or more locations of the routing graph to a starting point.
Abstract:
In one implementation, a method may comprise: determining a topological representation of an indoor portion of a building based, at least in part, on positions or number of lines in an image of the indoor portion of the building; and comparing the topological representation to one or more stored topological representations, for example in a digital map of the building, to determine a potential position of the indoor portion of the building.
