Abstract
For example, a method includes collecting orientation data from a mobile device as a user of the mobile device moves within an indoor space, generating orientation estimates for the mobile device from the orientation data, generating distance estimates representing distances of the mobile device to a wireless access point in the indoor space, storing the orientation estimates and the distance estimates together as a series of data blocks, constructing a plurality of trajectory segments from the orientation estimates, identifying identifiers for a last number of trajectory segments, using data blocks corresponding to the last number of trajectory segments, and identifying a predicted place within the indoor space to which the user is expected to go by using the identifiers to traverse a prediction tree, where branches of the prediction tree that are associated with the identifiers define a path that ends at a leaf node corresponding to the predicted place.
