The Location Manager aims to calculate the device pose (position and orientation) as accurate as possible using various input sources. The performance of pose e-stimation can be characterised by the following measures:
• Accuracy --> describes the average offset between real and estimated device pose
• Standard Deviation --> describes to which extend the estimated pose “jumps” around the real device pose
• Update Rate --> describes how often the device pose can be updated.
To maximise the performance, the Location Manager combines and filters estimated poses from various Pose Estimation Systems based on their estimated error levels. Pose Estimation systems can be activated and deactivated using the Pose Estimation Systems Setting. Currently the following pose estimation systems are available:
