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.

TL;DR: Five experts from the fields of postural and locomotor control present the work they have engaged in to understand how the brain uses multiple pathways of sensory feedback to organize movement behavior and how VR may help them understand or engage the mechanisms underlying sensorimotor integration.
Gravity estimation and verticality perception
TL;DR: Sensory information and computational processes underlying gravity estimation and verticality perception are reviewed, which serves to improve the precision of perception and resolve ambiguities in sensory representations by combining information from across the visual, vestibular, and somatosensory systems.
Electrical Stimulation of Semicircular Canal Afferents Affects the Perception of Head Orientation
TL;DR: It is suggested that motion-modulated stimulation of canal afferents by a vestibular prosthesis could potentially improve Vestibular percepts in patients lacking normalvestibular function.
Cybersickness without the wobble: Experimental results speak against postural instability theory
Mark Dennison,Michael D'Zmura +1 more
TL;DR: The link between postural instability and cybersickness is a weak one in the present experiment and the offset direction of perceived vertical settings matched the direction of the tunnel's rotation, so replicating earlier findings.
Four types of visual mental imagery processing in upright and tilted observers.
TL;DR: Performance in the image composition and detection tasks depended on body position, whereas there was no such effect for the transformation and resolution tasks.

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.
