Abstract: Methods, systems, computer-readable media, and apparatuses for reducing a set of access points to be used for mobile device positioning are presented. In some embodiments, a subset of access points may be selected from a set of access points. A trial set of access points may be generated by removing the subset of access points from the set of access points. A coverage quality may be determined for the trial set of access points. In response to determining that the coverage quality of the trial set of access points exceeds a threshold coverage quality, the subset of access points may be removed from the set of access points.

Abstract: Methods and devices are described for optimizing display of information such as map data on a mobile device. Certain embodiments may include receiving, at a mobile device, a first and second set of placement data associated with a first and second object. The mobile device may then determine overlap between a representation of the first object and the second object in a rendering of an image comprising the representation of the first object and the second object, using a set of viewing parameters, the first set of placement data and the second set of placement data. The set of viewing parameters may be adjusted to reduce overlap between the representation of the first object and the second object in the rendering of the image. In additional embodiments, 3D enhancements to two-dimensional map objects may be added to enhance the presentation of the information.

Abstract: Disclosed are devices, methods and storage media for use in determining position information for imaging devices or mobile devices. In some implementations, a landmark is identified in an image which is obtained from an imaging device which in turn is positioned at a location and in a pose. A virtual two-dimensional image that would be visible from the landmark is determined based, at least in part, on the pose. The location or position information is based, at least in part, on the virtual two-dimensional image.

Abstract: Techniques for displaying navigation information on a mobile device are provided that include a method that includes obtaining an indication of a position and an indication of a direction associated with the mobile device, using the indication of the position, the indication of the direction, information regarding identities of POIs within a geographic region of interest, and information regarding areas associated with the POIs to determine at least one relevant POI, of the POIs, that is associated with the position and direction, and displaying at least one visual indication associated with each of the at least one relevant POI on the mobile device. The appearance of the at least one visual indication is dependent on at least one of a distance from the mobile device of the relevant POI associated with the visual indication or presence of a known physical barrier between the mobile device and that relevant POI.

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.
