Abstract: A camera's field of view is determined using image data and location information. Accurate augmented reality representations are provided based on the determined field of view in an absence of a priori knowledge of the camera's field of view.

Abstract: Methods are disclosed for providing alternate reality (e.g., virtual reality) representations to users. Exemplary methods employ data collections (e.g., stacks) which affect the virtual representations of baseline virtual models. Data collections contain layers which contain deltas. The deltas specify modifications to the baseline virtual reality world or model. The deltas may be geocoded, while the layers that contain them may not be geocoded. Separately selectable layers are used to temporarily modify or substitute baseline data or virtual elements (e.g., virtual objects) that are ultimately presented to a user on an output device. Conflict resolution algorithms harmonize conflicts between layers of a collection.

Abstract: Methods and devices are disclosed which provide modification, editing, or extension of augmented reality and virtual reality representations of real world spaces using elevation information obtained from image processing of real world images.

Abstract: Augmented reality augmentations are selected or modified based on accuracy or confidence information concerning locations and orientations.

Abstract: A system and method for estimating the position of wireless devices within a wireless communication network combines measured RF channel characteristics for the wireless device with one or more predicted performance lookup tables, each of which correlates an RF channel characteristic to some higher order network performance metric and/or a position within an environmental model. Measured RF channel characteristics for wireless devices are compared against the performance lookup tables to determine the sent of lookup tables that most closely match the measured RF channel characteristics. The positions within the environmental model corresponding to the selected set of matching lookup tables are identified as possible locations for the wireless device. The performance lookup tables are uniquely constructed by site-specific location, technology, wireless standard, and equipment types, and/or the current operating state of the communications network.

Abstract: A computerized model provides a display of a physical environment in which a communications network is or will be installed. The communications network is comprised of several components, each of which are selected by the design engineer and which are represented in the display. Errors in the selection of certain selected components for the communications network are identified by their attributes or frequency characteristics as well as by their interconnection compatability for a particular design. The effects of changes in frequency on component performance are modeled and the results are displayed to the design engineer. A bill of materials is automatically checked for faults and generated for the design system and provided to the design engineer. For ease of design, the design engineer can cluster several different preferred components into component kits, and then select these component kits for use in the design or deployment process.
