READ ME File For 'Dataset in support of the thesis 'Motion Sickness During Low Frequency Lateral and Roll Motions in Isolation and in Combination: Effect of Visual Conditions with/without VR HMD Device' Dataset DOI: 10.5258/SOTON/D2814 ReadMe Author: Yahya Sumayli, University of Southampton ORCID ID 0000-0003-4850-5529 This dataset supports the thesis entitled 'Motion Sickness During Low Frequency Lateral and Roll Motions in Isolation and in Combination: Effect of Visual Conditions with/without VR HMD Device' AWARDED BY: Univeristy of Southampton DATE OF AWARD: 2023 DESCRIPTION OF THE DATA 1) The illness ratings: an illness rating scale (adapted from Golding and Kerguelen (1992)) was used to measure subjects’ motion sickness on a seven-point scale (from 0 to 6) during motion exposure. Subjects were asked every minute to rate their sickness using a number based on the illness rating scale (from 0 to 6) during motion exposure. Mean illness ratings were obtained by summing the illness ratings reported by a subject each minute and then dividing by the number of minutes of motion exposure. 2) The symptom scores: a symptom checklist was used to allow subjects to report symptoms they may experience during exposure to motion with/without use of a VR HMD device. Individual values for each symptom were added together to give a total symptom score. 3) MSSQ measures: Six measures of motion sickness susceptibility were obtained using responses from the motion sickness susceptibility questionnaire (MSSQ) devised by Griffin and Howarth (2000). This questionnaire was designed to determine how a person is susceptible to motion sickness, and what types of motion are most effective in causing that sickness (i.e., nausea, vomiting, etc.) in both land and non-land transport. The six measures of motion sickness susceptibility are illness susceptibility in the last year, Isusc(yr); vomiting susceptibility in the last year Vsusc(yr); total susceptibility to vomiting, Vtotal; total susceptibility to motion sickness in all types of transport, Mtotal; susceptibility to motion sickness in land transport, Mland; and susceptibility to motion sickness in non-land transport, Mnon-land. This dataset contains: Illness ratings, symptom scores and MSSQ measures, which are all described above. Date of data collection: The data were collected during four experiments from 2020 to 2022.
