Advanced Filtering Methods in Head Teleoperated Systems and Helmet Mounted Displays

Abstract

This paper address errors caused by vibration or turbulence in airborne helmet displays and teleoperation. It is shown by analysis and computer simulations that a modified version of the LMS adaptive noise suppression algorithm facilitates the separation of the large voluntary head movements from the vibration-induced small nonvoluntary head motion. Thus, the effects of the biodynamic interferences can be essentially removed. The results also indicate that errors in head tracking teleoperated devices can essentially be suppressed. Extensive man-in-the-loop laboratory simulations which validate the method are described. Biodynamic interference, Noise suppression, Adaptive filtering, Teleoperation, Helmet mounted displays.
