Towards Systematic Analysis of Cybersickness in High Motion Omnidirectional Video

Subjective Evaluation of Visual Quality and Simulator Sickness of Short 360$^\circ$ Videos: ITU-T Rec. P.919

“…• Vertigo Scale [83]: The single-question method proposed by Pérez et al, which evaluates simulator sickness stating the question "Are you feeling any sickness or discomfort now?" and using a five-grade scale (from "no problem" to "unbearable").…”

“…Also, Cybersickness Questionnaire (CSQ) was proposed by Stone III et al [80], derived from the SSQ by retaining only nine symptoms, also grouped by two factors (dizziness and difficulty focusing). In addition, there are quite a few single-scale questions such as Fast Motion Sickness Scale (FMS) [81], Misery Scale Index (MISC) [82], Vertigo scale [83], and Short SSQ [84] that can be used to assess sickness. This Short SSQ was compared to the long SSQ [76] in a subjective quality test with 360°videos, carried out by Singla et al [85].…”

“…Bad for 0 to 19, Poor for 20 to 39, and so on). Absolute Category Rating (ACR) is used by default, but others can be selected: Degradation Category Rating (DCR) and two different cybersickness scales [6], [7]. Custom 5-level categorical scales can also be added.…”

“…Several scales are included in the application: ACR, DCR, two simulator sicknes scales (Vertigo [6] and Dizziness [7]), and two 8-item presence scales: Spatial-Presence Experience Scale (SPES) [9] and mini-MEC-SPQ. Mini-MEC-SPQ is an aggressive subsampling of the MEC Spatial Presence Scale (MEC-SPQ) [10], using a single item for each of the 8 measured factors of Spatial Presence, instead of 4, 6 or 8 as in the original publication (Table I).…”
