The Relationship between Spatial Velocity, Vection, and Visually Induced Motion Sickness: An Experimental Study
Open accessAbstract
Spatial velocity (SV), a product of scene complexity and navigation velocity, is a metric to quantify virtual scene movement for the study of visually induced motion sickness (VIMS) (So et al., 2001). As SV increases, VIMS increases, peaks, and then decreases. Watching VIMS provoking stimuli of similar SV is hypothesized to produce similar levels of vection and VIMS. An experiment was conducted to test the hypothesis. Ten participants were exposed to five visual motion oscillating along fore-and-aft axis at different frequencies (from 0.05 to 0.8Hz). The r.m.s. velocity was kept constant and the frequency changes were achieved by changing the amplitudes of oscillation. These five stimuli had similar SVs. To our surprise, participants reported significantly different vection as the frequency increased even though the SVs were kept the same (p < 0.001). Levels of VIMS was not significantly different because the exposure duration was too short (20 seconds). A second experiment using stimuli with 30 minutes was conducted. Preliminary results indicated that levels of nausea significantly changed when viewers were exposed to visual oscillations with similar SVs but different frequency. Modifications to the previously reported SV metric are proposed.

Each is checked against this paper’s own text: does it say what the citing paper says it does?
Bonato et al. (2009) found that dual-axes rotations elicited more VIMS than single-axis rotations, while the level of vection remained unchanged.
“Although dual-axes rotations elicited more VIMS, the level of vection remained unchanged compared to the single-axis condition.”

The available indexed passages contain only article information and publication metadata (no section or page label). Searches for Bonato et al. (2009) and for the dual-axis versus single-axis comparison found no passage addressing VIMS or vection levels, so the claim cannot be checked against our copy. (LLM, conf=0.72)

“For example, Bonato et al. (2009; see also Chen et al., 2011) exposed their participants to a video containing optic flow rotations along a single axis or along a combination of two axes.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
