Time-varying perceived motion mismatch due to motion scaling in curve driving simulation

Effects of Motion Cueing on Curve Driving

A curve negotiation task at a prescribed and constant velocity was performed in the presence of external disturbances. The driver’s goal was to simultaneously minimize the heading error and lateral position error. The present paper investigates the separate contributions of the road tracking and the disturbance to the heading and position errors, and more important, the effect of motion on thes...

Illusory motion due to causal time filtering

A new class of patterns, composed of repeating patches of asymmetric intensity profile, elicit strong perception of illusory motion. We propose that the main cause of this illusion is erroneous estimation of image motion induced by fixational eye movements. Image motion is estimated with spatial and temporal energy filters, which are symmetric in space, but asymmetric (causal) in time. That is,...

High Accuracy Relative Motion of Spacecraft Using Linearized Time-Varying J2-Perturbed Terms

This paper presents a set of linearized equations was derived for the motion, relative to an elliptical reference orbit, of an object influenced by J2 perturbation terms. Approximate solution for simulations was used to compare these equations and the linearized keplerian equations to the exact equations. The inclusion of the linearized perturbations in the derived equations increased the high ...
