    • Example methods, apparatuses, or articles of manufacture are disclosed herein that may be utilized, in whole or in part, to facilitate or support one or more operations or techniques for logo detection for indoor positioning for use in or with a mobile device. Briefly, in accordance with one implementation, a method may include extracting, at a mobile device, visual features from one or more images captured via a camera sensor of the mobile device; and estimating a location of the mobile device based, at least in part, on a match between extracted visual features and one or more brand-specific visual signatures associated with one or more points of interest of one or more known locations. In some instances, an estimated location of a mobile device may be refined based, at least in part, on at least one additional POI of one or more POIs of one or more known locations.

    • The subject matter disclosed herein relates to systems, methods, apparatuses, articles, and means for determining at least one navigational coordinate system to be utilized in conjunction with transports and/or mobile devices. For certain example implementations, a method by a mobile device that is at least proximate to a transport may comprise identifying a first navigational coordinate system, with the first navigational coordinate system being associated with the transport and enabling navigation within at least one navigable area of the transport. A second navigational coordinate system may also be identified. The mobile device may determine to utilize at least one of the first navigational coordinate system or the second navigational coordinate system based, at least in part, on one or more predetermined conditions. Other example implementations are described herein.
    • 本文公开的主题涉及用于确定要与传送和/或移动设备结合使用的至少一个导航坐标系统的系统,方法,设备,物品和装置。 对于某些示例性实施方式,移动设备至少邻近传输的方法可以包括识别第一导航坐标系,其中第一导航坐标系与传输和启用导航在至少一个可导航区域内相关联 运输。 还可以识别第二导航坐标系。 至少部分地基于一个或多个预定条件,移动设备可以确定利用第一导航坐标系或第二导航坐标系中的至少一个。 本文描述了其他示例实现。

    • The subject matter disclosed herein relates to systems, methods, apparatuses, devices, articles, and means for map handling for location based services in conjunction with localized environments. For certain example implementations, a method may comprise storing map information corresponding to a particular localized environment that is associated with a particular location context identifier, with the particular localized environment comprising an indoor environment corresponding to at least a portion of a building structure; receiving update information applicable to the map information corresponding to the particular localized environment, with the update information being associated with the particular location context identifier; updating the map information corresponding to the particular localized environment based at least partly on the update information so as to produce updated map information; and providing the updated map information to one or more mobile devices that are located at the particular localized environment. Other example implementations are described herein.
