Panagiotis Kourtesis, Josie Linnell, Rayaan Amir, Ferran Argelaguet, and Sarah E. MacPherson

TL;DR
This study introduces and validates the Cybersickness in VR Questionnaire (CSQ-VR), demonstrating its superior reliability and sensitivity over existing tools like SSQ and VRSQ for assessing cybersickness during VR experiences.
Contribution
The paper develops and validates the CSQ-VR, a new cybersickness assessment tool with better psychometric properties and the ability to incorporate pupil size as a biomarker.
Findings
CSQ-VR shows higher internal consistency than SSQ and VRSQ.
CSQ-VR better detects temporary performance declines due to cybersickness.
Pupil size predicts cybersickness intensity.
Abstract
Cybersickness is a drawback of virtual reality (VR), which also affects the cognitive and motor skills of the users. The Simulator Sickness Questionnaire (SSQ), and its variant, the Virtual Reality Sickness Questionnaire (VRSQ) are two tools that measure cybersickness. However, both tools suffer from important limitations, which raises concerns about their suitability. Two versions of the Cybersickness in VR Questionnaire (CSQ-VR), a paper-and-pencil and a 3D-VR version, were developed. Validation and comparison of CSQ-VR against SSQ and VRSQ were performed. Thirty-nine participants were exposed to three rides with linear and angular accelerations in VR. Assessments of cognitive and psychomotor skills were performed at baseline and after each ride. The validity of both versions of CSQ-VR was confirmed. Notably, CSQ-VR demonstrated substantially better internal consistency than both SSQ…
