Here’s Prothero. A pain in the ass this one was, but I got to try out some new ways of coloring lines and playing with layers

I am writing a 6 page paper 8 hours before it is due. I have work tomorrow. I am trash. I might also be hallucinating? And I just finished giggling about Shango who "pulls energy from the sky into his genitals" for 7 minutes straight.

Abstract

Background: Simulator sickness (SS) is a major problem which potentially limits interface applications that feature simulated motion. While display imperfections play a role, a large part of SS is motion sickness (MS). Sensory rearrangement theory holds that MS is related to conflicting motion cues; in the case of simulators, mainly a conflict between inertial cues (usually indicating no self-motion) and visual stimuli from the display (indicating self-motion). It is suggested that MS does not arise from conflicting motion cues per se, but rather from conflicting rest frames selected from those motion cues. There is strong evidence that the visual rest frame is heavily influenced by the visual background. Providing an independent visual background (IVB) consistent with the inertial rest frame may reduce SS, even when the simulator's content-of-interest (CI) is not consistent with the inertial rest frame. Methods: In two experiments, a circular vection stimulus was shown for 3-4.5 min in a head-mounted display, comparing see-through (i.e., IVB) to occluded (i.e., no IVB) modes. Measures included a standard SS questionnaire and a pre-exposure ataxia measure. Experiment 2 added a visual task which forced attention into the CI and a post-exposure ataxia measure. In both experiments, subjects rated the CI as significantly more visible than the IVB. Results: A large effect was found for the reduction of SS and ataxia in the first experiment, and for pre-exposure ataxia in the second. Conclusions: Future research will further test the IVB idea and examine applications to high-end simulators.
