“…Similar vection advantages can be produced by adding horizontal/vertical simulated viewpoint oscillation to radial and lamellar patterns of constant velocity optic flow (Kitazaki and Hashimoto, 2006;Nakamura, 2010;Palmisano et al, 2007Palmisano et al, , 2008Palmisano and Kim, 2009). As with the simulated viewpoint jitter advantage for vection, this simulated viewpoint oscillation advantage is remarkably robust to changes in amplitude (0-1/3 to 0-1/5 of the forwards speed) and frequency (0.14-7.4 Hz).…”

“…Research suggests that viewpoint jitter and oscillation improve the vection experience by tapping into specialized processes used to perceive self-motion from naturally occurring patterns of optic flow (Bubka and Bonato, 2010;. While some recent research suggests that simulated viewpoint oscillation may improve vection by increasing the perceived rigidity of the optic flow (Nakamura, 2010), other evidence suggests that the mechanisms underlying these jitter/oscillation based improvements may be increased retinal slip (Palmisano and Kim, 2009) or reduced adaptation. Such studies have brought us tantalizingly close to a full understanding of the role of sensory conflict in the genesis of vection.…”

“…Thus, one possible explanation for the jitter advantage in vection is that jitter-induced optokinetic responses (OKRs) indirectly stimulated the vestibular cortex of our stationary subjects (e.g., via the mid-brain oculomotor pathways). It should be noted, however, that this eye-movement based explanation would have difficulty accounting for why the jitter advantage for vection persists when the observer keeps his/her eyes stationary (e.g., Palmisano and Kim, 2009). …”

“…To test the role that retinal slip plays in vection, Palmisano and Kim (2009) had their subjects engage in the following three different types of gaze while viewing jittering, oscillating and purely radial patterns of optic flow: (i) central/peripheral stationary fixation; (ii) central/peripheral directed looking; and (iii) gaze shifting from the centre of the display to the periphery. They found that simulated viewpoint oscillation always improved the vection in depth induced by radial flow, irrespective of whether instructions were to fixate, or look at, the centre or periphery of the display.…”

Sensory conflict has been used to explain the way we perceive and control our self-motion, as well as the aetiology of motion sickness. However, recent research on simulated viewpoint jitter provides a strong challenge to one core prediction of these theories -that increasing sensory conflict should always impair visually induced illusions of self-motion (known as vection). These studies show that jittering self-motion displays (thought to generate significant and sustained visual-vestibular conflict) actually induce superior vection to comparable non-jittering displays (thought to generate only minimal/transient sensory conflict). Here we review viewpoint jitter effects on vection, postural sway, eye-movements and motion sickness, and relate them to recent behavioural and neurophysiological findings. It is shown that jitter research provides important insights into the role that sensory interaction plays in self-motion perception.

“…Apart from fixation and staring, peripheral looking and gaze shifts between central and peripheral regions can also improve forward linear vection (Palmisano & Kim, 2009). Potential factors underlying this effect include faster local image velocities and increased retinal slip (local image velocity is higher in the periphery for radially expanding flow fields) as well as screen boundary effects as described in the following.…”
