摘要： A method and a device for determining a device placement to optimize techniques, such as power management techniques, are described. The method, executed in a processor of a mobile device, comprises gathering data from at least one sensor associated with the mobile device. Based on the data gathered from the sensor, a device placement indicative of at least one of an orientation and a position the mobile device may be determined. Further, details pertaining to the device placement may be integrated with secondary classification data comprising at least one of historical data, device orientation data, and device motion data. Based on the integrated details, it may be inferred whether a user is engaged with the mobile device. When a user is not engaged with the mobile device, a brightness of the display is lowered in at least one stage to optimize power consumption and user experience.

摘要： A method and system for detecting an indoor threshold transition in a positioning state. The method may be executable using one or more processors and comprises, upon detecting a pattern of magnetic anomaly characteristics associated with a sequence of position changes of the mobile device, extracting the pattern, comparing the extracted pattern with a stored magnetic signature associated with the indoor threshold, and based on the comparing, inferring that the mobile device is one of transitioning in position and has transitioned in position across the indoor threshold.

摘要： A method and system for localizing a mobile device having a processor and a memory. The method comprises, using the processor, localizing the mobile device during navigation of a sequence of positions along an indoor area based on a data fusion of fingerprint data, detecting, using the processor, a boundary of a trusted-global positioning system (trusted-GPS) positioning region within the indoor area, and upon navigating to the boundary, localizing the mobile device based on GPS position data acquired at the memory of the mobile device.
