Description: Under conditions of misaligned, or non-natural, visual-motor mappings, accurate spatial control of human movement is difficult. Historically operators have learned to compensate for these misalignments through extensive practice. A display concept is proposed to facilitate adaptation to this control difficulty by providing historical and predictive trajectory information using an augmented reality technique. An experimental platform to test the display concept is developed. The rapid adaptation to several rotationally misaligned visual-motor mappings conditions is tested with three modes of the proposed display (historical information, predictive information, and both) and a control using a sequential aiming task. Global performance measures, analysis of trajectory characteristics, and correlations with spatial abilities are reported. The performance detriment of the rotational misalignments follows the typical pattern of results seen in the literature. Predictive information appears to assist adaptation to some conditions of misaligned visual-motor mappings; however this finding is highly constrained.
