Patent: User aware odometry correction technology

Publication Number: 10191539

Abstract

Systems, apparatuses and methods may provide for technology to detect a pose drift condition with respect to a head mounted display based on one or more first signals, to detect a reduced perception state with respect to the head mounted display based on one or more second signals, and to trigger a correction of the pose drift condition during the reduced perception state. Additionally, the reduced perception state may correspond to, for example, a blinking condition, a saccadic motion condition and/or an increased head rotation rate.

Background

Augmented reality (AR) and virtual reality (VR) applications may estimate headset motion (e.g., rotation and translation) over time (“odometry”). Some headsets may operate based on inside-out tracking (e.g., MICROSOFT HOLOLENS). Inside-out tracking may lack an absolute reference landmark and thus may introduce an accumulating error (“drift”) in the pose of the user. While there may be methods to correct the drift, human perception may be very sensitive to any inconsistencies or discontinuities introduced by such corrections.
