    摘要: Various methods, apparatuses and articles of manufacture may be implemented for use in one or more computing platforms to adaptively provide and/or obtain indoor navigation assistance data (INAD) update(s) for use by a mobile device. An INAD update may, for example, comprise a subset of INAD available for an indoor environment. Such a subset may be determined based, at least in part, on a bounded region in an electronic map of the indoor environment. Such a bounded region may, for example, have a shape and/or a size based, at least in part, on at least one parameter indicative of a motion state of the mobile device.

    摘要: The subject matter disclosed herein may relate to methods, apparatuses, systems, devices, articles, or means for facilitating mobile device positioning. For certain example implementations, a method for a mobile device may comprise identifying an uncertainty of at least one estimate of a location of the mobile device. Signals to acquire that are transmitted from multiple transmitters for use in at least reducing the uncertainty of the at least one estimate of the location of the mobile device may be prioritized based, at least in part, on one or more characteristics associated with the multiple transmitters and at least one constraint on the at least one estimate of the location of the mobile device in accordance with a navigational path of the mobile device. Other example implementations are described herein.

    摘要: The subject matter disclosed herein relates to systems, methods, devices, articles, apparatuses, means, etc. for mobile device positioning in a constrained environment. For certain example implementations, a method may comprise obtaining an estimated velocity distribution and an estimated direction of movement distribution of a mobile device for a current position based at least in part on routability information for a constrained environment. A subsequent position of the mobile device may be estimated based at least in part on the estimated velocity distribution and the estimated direction of movement distribution for the current position. Other example implementations are described herein.

    摘要: Techniques for determining the position of a mobile wireless device are provided. The techniques include a method for determining the position of a mobile wireless device that includes receiving signal characteristics of a signal received from the mobile wireless device at a wireless access point of a Wireless Local Area Network (WLAN), determining an orientation of the mobile wireless device relative to the wireless access point, determining a compensation factor based on the orientation of the mobile wireless device relative to the wireless access point, and determining an estimated position of the mobile wireless device based at least in part on the compensation factor. The compensation factor compensates for the effect of user occlusion on at least one characteristic of the signal received from the mobile wireless device.

    摘要: Techniques are provided that may be implemented in various methods and apparatuses to allow an electronic device to determine when it is transitioning or has transitioned from a first environment to a second environment based, at least in part, on at least one measured parameter. The measured parameter may be based, at least in part, on one or more received wireless signals associated with one or more wireless signal transmitters, and/or one or more signals associated with one or more non-radio sensors. The electronic device may then affect operation of a navigation function (e.g., having a trajectory estimation filter) based, at least in part, on the measured parameter.

    摘要: Various techniques are provided which may be implemented in one or more methods, apparatuses, and/or articles of manufacture for use with and/or in a mobile device to obtain this date/trajectory estimation us within an indoor environment. In an example, a mobile device may apply a motion model to propagate an estimated state of the mobile device from a first state corresponding to a first location of an electronic map representing an indoor environment to a second state corresponding to a second location of the electronic map, based, at least in part, on one or more sensed parameters. The mobile device may further validate the estimated state as propagated in response to a determination that a trajectory from the first location to the second location crosses a transition feature of a barrier presented by at least one obstacle identified in the electronic map.
