Moving visual scenes influence the apparent direction of gravity.
TL;DR: When an observer views a wide-angled display rotating around his line of sight, he both feels his body tilted and sees a vertical straight edge tilted opposite to the moving stimulus.

Abstract: When an observer views a wide-angled display rotating around his line of sight, he both feels his body tilted and sees a vertical straight edge tilted opposite to the moving stimulus. Displacement of the perceived vertical increases with stimulus speed to reach a maximum (averaging 15 degrees) at 30 degrees per second.

A theory of visual stability across saccadic eye movements
TL;DR: From a review of the physiological and psychological evidence, it is concluded that no subtraction, compensation, or evaluation need take place and the problem for which these solutions were developed turns out to be a false one.
Neural Processing of Gravito-Inertial Cues in Humans. IV. Influence of Visual Rotational Cues During Roll Optokinetic Stimuli
L. H. Zupan,Daniel M. Merfeld +1 more
TL;DR: It is predicted that illusory tilt caused by roll optokinetic cues should lead to a horizontal vestibuloocular reflex compensatory for an interaural estimate of linear acceleration, even in the absence of actual linear acceleration.
Representation of Gravity-Aligned Scene Structure in Ventral Pathway Visual Cortex.
TL;DR: The ventral visual pathway in humans and non-human primates is known to represent object information, including shape and identity, but this work shows the ventral pathway also represents scene structure aligned with the gravitational reference frame in which objects move and interact.
Perception of postural verticality in roll and pitch while sitting and standing in healthy subjects.
Jeannine Bergmann,Standislav Bardins,Christian Prawitz,Aram Keywan,Paul R. MacNeilage,Klaus Jahn +5 more
TL;DR: Even though the SPV assessment while sitting and standing resulted in similar mean values, the larger variability and the higher sensitivity to visual stimuli while sitting suggest different strategies for verticality estimation while Sitting and while standing.
Multisensory contribution in visuospatial orientation: an interaction between neck and trunk proprioception
Jason McCarthy,Patricia Castro,Patricia Castro,Patricia Castro,Rachael Cottier,Joseph Buttell,Qadeer Arshad,Qadeer Arshad,Amir Kheradmand,Diego Kaski +9 more
TL;DR: In this article, the authors investigated the contribution of proprioception to verticality perception and further investigated whether changing the body position without moving the head can modulate visual dependence, the extent to which an individual relies on visual cues for spatial orientation.

Differential Effects of Central Versus Peripheral Vision on Egocentric and Exocentric Motion Perception
TL;DR: Simultaneous presentation of conflicting central and peripheral optokinetics stimuli has shown that exocentric orientation depends on the peripheral stimulus whereas optokinetic nystagmus and egocentric motion perception rely on the center of the visual field.
