  • Publication number: 20140253371
    Abstract: Disclosed are apparatuses and methods for enabling the use of global navigation satellite system (GNSS) signals indoors. The method may include determining a first indoor position of the mobile device based on indoor transceiver signals. The method may also include determining, based at least in part on the determined first indoor position, that global navigation satellite system (GNSS) positioning signals are available. The method may also include determining a second indoor position of the mobile device based, at least in part, on GNSS positioning signals.

  • Publication number: 20140257687
    Abstract: An embodiment is directed to generating a polygon representation of a plurality of points of interest (POIs) in a scene having a corresponding base level map of the scene, and creating a new level map including a reduced number of polygon representations of POIs on the basis of elimination of POIs having a lower than specified POI importance level. In another embodiment, a mobile device (e.g., the user device) can specify the specified POI importance level to trigger the generation and delivery of the new level map which conforms to the specified POI importance level so that the new level map can be displayed to a user of the mobile device (e.g., in conjunction with navigation instructions to one or more of the remaining POIs).

  • Publication number: 20140253582
    Abstract: Methods, apparatuses, and devices for rendering indoor maps on a display device of, for example, a mobile device, are presented. In one example, a processor of a mobile device may receive identifiers, such as alphanumeric identifiers, for points of interest (POI) and map at least portions of the identifiers to colors within a suitable color space, such as a RGB color space.

  • Publication number: 20140240350
    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.

  • Publication number: 20130205202
    Abstract: Systems and methods are provided for transforming a document into interactive media content. A system can include a memory for storing computer executable instructions and a processing unit for accessing the memory and executing the computer executable instructions. The computer executable instructions can include an engine to generate a dynamic composition of the text blocks and visual blocks of the document, based on semantic features of the text blocks and the visual blocks, to provide the interactive media content.

  • Publication number: 20090113350
    Abstract: A system and method of visually summarizing a hierarchically structured set of digital objects and for facilitating efficient access to such objects through the selection of representative summary objects. These digital objects are typically media objects such as digital image files, digital video clips, digital audio objects, such as “MP3” files, or other digital documents, such as text documents, that can be collected by a user and distributed over a variety of storage media and storage locations.
