There are some who still question that motion cues enhance simulation. While we will concede that no motion is better than bad motion, this paper investigates three widely used motion algorithms vs. simming static; with no motion.

Motion Algorithms vs. Simming Static

The coordinated adaptive motion control algorithm was perceived as the most immerse for professional pilots with almost complete dislike of the simulation without motion cues; a static cockpit.

The study was conducted on a state-of-the-art six-degrees-of-freedom Stewart platform[1]. This same platform has been found, by one of the authors, to be adequately replaced by a 3 DOF rotational sim[2]; like the SimCraft sc830.

The three algorithms studied were the classical washout method, and two circa 1988; optimal control and the more accepted nonlinear coordinated adaptive motion simulation algorithm. The sim was also turned off and thus into a static simulator cockpit.

Professional pilots were studied during simulation of aerodynamic force as well as a full set of ground handling equations developed for the study. The conclusion reached by this study is that correct motion cues are preferred over no motion.
