Roll motion stimuli: sensory conflict, perceptual weighting and motion sickness

Brain Research Bulletin, 1998
In an experiment with 17 subjects, interactions of visual roll motion stimuli and vestibular body tilt stimuli were examined in determining the subjective vertical. Interindividual differences in weighting the visual information were observed, but in general, visual and vestibular responses added in setting the vertical. Despite the conflicting sensory

Ship Roll Motion Control [PDF]

, 2010
The technical feasibility of roll motion control devices has been amply demonstrated for over 100 years. Performance, however, can still fall short of expectations because of deciencies in control system designs, which have proven to be far from trivial due to fundamental performance limitations.

Rolling Perception without Rolling Motion

Perception, 2008
The texture of a rolling circle depicts the translational and rotational components of its motion. In the case of a homogeneous circle, however, visual cues to the rotational component of motion are absent. To examine how the visual system resolves undetermined motion cues, optically neutral circles were displaced so that changes in their orientation ...

Method rolls for Simulating Roll Motions of Ships

Ship Technology Research, 2013
Method rolls was developed to simulate non-linear roll motions of ships. The method was described already by Kroger in 1986, however in German language. Because the method is used frequently even now, this paper documents the method in English, including developments made in the meantime, but excluding the extension to damaged ships.

Planning motions of rolling surfaces

Proceedings of 1995 34th IEEE Conference on Decision and Control, 2002
Rolling between rigid surfaces in space is a well-known nonholonomic system, whose mathematical model has some interesting features that make it a paradigm for the study of some very general systems. It also turns out that the nonholonomic features of this system can be exploited in practical devices with some appeal for engineers. However, in order to

Motion planning of rolling surfaces

Proceedings of the 40th IEEE Conference on Decision and Control (Cat. No.01CH37228), 2002
In this paper, we address the issues of controllability and motion planning for the control system S/sub R/ that results from the rolling without slipping nor spinning of a two dimensional Riemmanian manifold M/sub 1/ onto another one M/sub 2/. In the first part of the paper, we describe precisely the control system under consideration together with ...
