摘要:
Systems, apparatuses, and methods for correcting systematic errors in positional data of electronic devices configured to navigate across a surface. An apparatus configured to correct positional errors may comprise one or more navigation sensors, and a position module configured to control the one or more navigation sensors to capture a plurality of navigational measurements and adjust the navigational measurements by one or more scaling factors to determine a translation path of the apparatus over a medium. The one or more scaling factors may be constructed by capturing a plurality of navigational measurements to determine a detected translation path of an apparatus, comparing an actual translation path of the apparatus to the detected translation path of the apparatus, and generating the one or more scaling factors based at least in part on a difference between the actual translation path and the detected translation path. Other embodiments also are described.
