1. A method for tracking a user, the method comprising: receiving a depth image that includes a target; scanning a first orientation to a first side of the target; scanning the first orientation to a second side of the target; identifying a first point of reference on the target from the scan of the first orientation; scanning a second orientation to a third side of the target, based on the first point of reference; scanning the second orientation to a fourth side of the target; identifying a second point of reference on the target from the scan of the second orientation; generating a bounding box based on the reference point of the scan of the first orientation and the reference point of the scan of the second orientation; and using the identified bounding box to adjust a model of the target.
