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: 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 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: Methods and apparatus for processing positioning data are provided. In an example, a method for processing positioning data associated with one or more access points includes choosing, for inclusion in the positioning data, one or both of: (1) ranging model parameters to enable a mobile device to compute first heatmap data for multiple points in a ranging region of a heatmap, or (2) second heatmap data for a plurality of points in a non-ranging region of the heatmap. The method can also include transmitting the positioning data, such as to a mobile device. The positioning data can also include both the ranging model parameters and the second heatmap data when the ranging region and the non-ranging region fully or partially overlap, in which case the second heatmap data provides correction data to enable the mobile device to modify the computed heatmap data in the area where the two regions overlap.

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.

Points in at least a majority of a linear length of the path may be constrained so that they are disposed substantially equidistant between structural features that are bounding navigable spaces in a structure. The creating of the path may include selecting a connected component corresponding to some or all of the navigable spaces. A morphological process may be performed on the connected component to create the path.
