Thank you for your interest in our pilot study on web-based Virtual Reality interactions! Please read the following information carefully and, if you choose, provide your consent. If anything is unclear or if you need more information, please contact the study team.

Overview. We want to understand if web-based VR technologies can be used for behavior experiments. Participation in this psychological experiment consists of two parts. In the first part, we will assess basic demographic variables (age, weight, handedness) and personal opinions regarding health, gaming, and eating. In the second part, we will forward you to a simple web-based Virtual Reality environment, in which you will have to collect items with your VR-controller. Please complete the entire survey from within your VR-setup on a webXR-compatible browser (you will have to enable webXR in the second part).

The entire procedure will take about 15-20 minutes.
You need a 6-DOF VR headset (Oculus Rift, Quest, HTC-Vive) and webXR-enabled browser to complete the study! Unfortunately, Oculus Go, Samsung Gear VR, and Playstation VR, as well as Safari browser are not supported! 

Contact information. This study is a student project by psychology bachelor and master students at the University of Tübingen, Germany, supervised by Dr Philipp Schröder (philipp.schroeder@uni-tuebingen.de).

Study aim. To stop an already initiated action is a crucial ability. Here, we test a novel Virtual Reality (VR) web-based test to measure stopping on VR headsets with motion controllers, such as Oculus Quest, HTC-Vive, and OpenVR headsets. We want to understand if people's attitudes influence their stopping abilities.

What to expect. This study involves some short questionnaires on your demographic variables (age, experience with VR, weight and height) and attitudes towards eating. Next, you will be forwarded to a VR scene in which you have to pick up objects and regularly interrupt your movements. In the questionnaires, there are many similar items; these items are designed on purpose to answer our research questions. There are no open questions. The whole procedure will take 15-20 minutes.

Who can participate. To participate, you must be at least 18 years old. Everyone from within a VR headset with motion controllers (e.g., Touch, Wand, or Knuckle controllers for Oculus Quest, Oculus Rift, HTC-Vive) can participate in the study. If you are uncertain regarding your device, or if you experience any technical issues with access to the subsequent page, please contact Philipp (philipp.schroeder@uni-tuebingen.de).

Anonymity & Confidentiality. All information you provide will only be seen by the responsible researchers working on this project and not be shared in non-anonymised form. We will only collect and record non-personal data from you. 
Use of your data. The data collected in this study will be presented as part of academic papers or presentations. All data are processed and stored on dedicated servers of the research institution in Germany. Once we complete data analysis, we may store all data in an anonymised form online on a dedicated framework such as the Open Science Framework (OSF) website, which allows other researchers to check on our analyses and potentially run their own analyses on the data. At that point, we will delete all other data we have of you. We not collect personal identifiable information such as your email or IP address.
Possible risks. As we invite you to reflect on your current mood and attitudes towards gaming and eating, you may think of unpleasant or distressing events and experiences in your current life situation. This may cause you distress similar to thinking or telling a friend or relative about these events and experiences.

Further information. Participation in this study is entirely optional and you can withdraw from the study at any point in time. We can only include full submissions including both parts of the study in our data analysis. If you decide not to take part, you can simply close the browser page, there are no disadvantages. You can cancel your participation at any point in time.
