VR User Study, 30min, $20

To Whom It May Concern:


We are looking for participants in our study that aims to evaluate a novel virtual reality (VR) exploration method that allows users to see around any number of corners. The study will take up to 30 minutes of your time. You will be compensated with a $20 Amazon gift card. Please see eligibility requirements below. Please also see the VR headset manufacturer’s warnings below.


We will collect the following data: how much you moved through the virtual environment, how much you rotated the view direction, and how many times you jumped from one virtual environment location to another. We will also collect your answers to a simulator sickness questionnaire, system usability questionnaire, and presence questionnaire. We will also collect the following data on a voluntary basis: age, gender, and experience with VR applications.


The study will be conducted in August-September 2023. If you are interested in participating, please email the experimenter Shuqi Liao at liao201@purdue.edu.

VR headset manufacturer’s warnings

Pre-Existing Medical Conditions


Consult with your doctor before using the headset if you are pregnant, elderly, have pre-existing binocular vision abnormalities or psychiatric disorders, or suffer from a heart condition or other serious medical condition.




Some people (about 1 in 4,000) may have severe dizziness, seizures, eye or muscle twitching or blackouts triggered by light flashes or patterns. This may occur while they are watching TV, playing video games, or experiencing virtual reality, even if they have never had a seizure or blackout before or have no history of seizures or epilepsy. These symptoms arise more commonly in children and young people. Anyone who experiences any of these symptoms should stop use of the headset and see a doctor. If you previously have had a seizure, loss of awareness, or other symptom linked to an epileptic condition you should see a doctor before using the headset.


Interference with Medical Devices


The headset and controller(s) may contain magnets or components that emit radio waves, which could affect the operation of nearby electronics, including cardiac pacemakers, hearing aids, and defibrillators. If you have a pacemaker or other implanted medical device, consult your doctor or the manufacturer of your medical device before using the headset or controllers. Maintain a safe distance between the headset and controller and your medical devices. Stop using the headset or controller(s) if you observe a persistent interference with your medical device.
