You are being invited to take part in a questionnaire regarding the usability of Virtual Reality Head-Mounted DIsplays (VR HMDs), which should take approximately 10 minutes to complete.Before you continue, please take time to read the following information carefully. If there is anything that is unclear, or you would like more information, please feel free to contact us, at the email addresses listed below. Participation is optional, and the questionnaire can be exited at any time. You must be aged 18 or over to take part.Researcher (PhD Student): Mark McGill Supervisor: Professor Stephen Brewster The purpose of this study is to gain an insight into current VR HMD usage habits (e.g. where are they used, what for, who is present etc.), as well as investigating potential day-to-day issues with their usage.You will be asked to answer a series of optional questions, predominantly multiple choice, with some optional written statements, lasting approximately 10-12 minutes in total. All information will be stored securely and kept anonymous. There is a completely optional question asking for your name and email address, if you wish to be notified of further studies in this area, but this information will be kept confidential and will be used only for contact purposes in the event of future research. For taking part in the survey, you will be entered into a draw for a £10 Amazon gift voucher (contact email required).Similarly, there is an optional question asking respondents to email us a picture of their typical VR HMD usage environment; these pictures may potentially be used in a publication, however with any obviously personally identifiable details censored/blurred. If you wish to take part in this aspect of the survey, please read the requisite question thoroughly and tick the checkbox in the form then email us your picture (n.b. if you do not tick the box, we cannot use your picture).The results of this study may end up being used in research publications, and possibly a doctoral thesis, but again with emphasis that all results will be anonymized. By hitting the "next" button you give your consent for the data you provide to be used, as described above.This project is part of an industrial studentship PhD being conducted at the University of Glasgow.
