Participant Information Sheet
- What am I being invited to do?
You are invited to allow data collected during your use of the BrainEye application to be used for research purposes.
You are seeing this information because you are using the BrainEye app and are legally able to provide consent in your region, or a parent, guardian, or other person with lawful authority to provide consent on behalf of the BrainEye app user. This document explains the research use of the data collected during the use of The BrainEye app, and will help you decide whether you wish to provide consent.
Your decision to allow or not allow research use of the data is entirely voluntary.
- What is the purpose of this study?
The purpose of this research is to better understand normal and altered eye movements as measured using smartphone technology.
By analysing eye movement data from a large and diverse group of users, we aim to:
● characterise patterns of normal and altered eye movements
● develop and validate algorithms that measure eye movement behaviour
● improve the performance and scientific validity of eye-movement-based digital biomarkers
● publish aggregated research findings in scientific journals and presentations
This research uses data that have already been collected during your use of the app. No additional tasks, tests, or data collection are required.
- Do I have to take part and can I change my mind?
No. Taking part in this research is completely voluntary. You or the person you are providing consent for, can continue to use the BrainEye app without consenting to research.Your decision will not affect access to the app or its features.
If you consent and later change your mind, you may withdraw your consent at any time without giving a reason.
If you withdraw:
● the data will be removed from future research analyses
● the data will also be removed from any aggregate research datasets or models where feasible
Withdrawal will not affect the ongoing use of the app.
- What do I have to do?
If you agree to take part, you will be asked to:
- Read this Participant Information Sheet
- Provide your electronic consent within the app by checking the box
No additional actions, tests, or appointments are required.
- Your time and expenses
There is no payment or cost associated with this research. Participation involves only the secondary use of data already collected during app use.
- What are the benefits of taking part?
There is no direct benefit to you for participating. The potential benefits are indirect and include contributing to scientific knowledge and the development of improved tools for measuring eye movements and brain function.
- What are the risks and discomforts?
This is an observational research study that uses existing data collected during your normal use of the BrainEye app. No additional tests, tasks, or interactions are required for research purposes.
The overall risks associated with this research are low.
The main potential risk relates to privacy, as the data include eye-movement information derived from video recordings of your face. These privacy risks are not new and are the same as those that apply to normal use of the app.
Information about how your data are collected, stored, protected, and transferred is provided in the BrainEye Terms and Conditions and Privacy Policy, which apply to all users of the app.
This research does not involve:
● any additional data collection beyond normal app use
● any additional video recording
● any changes to how your data are stored, protected, or transferred
● any new sharing of identifiable information
As a result, consenting to research does not increase your privacy risk beyond what already exists through use of the app.
No new physical, psychological, or medical risks are introduced by this research. No individual research results will be provided.
What sensitive information is being collected? BrainEye application will use your phone’s camera to record a video of your face and eye movements. This video is considered sensitive information because it is a recording of you.
How will my identity and privacy be protected? We take your privacy and the security of your data very seriously. We have put multiple layers of protection in place to ensure your information is kept safe and confidential:
7.1. De-identification: All of your data is coded using an alphanumeric identifier. While research datasets are coded and de-identified, there is a technical capacity for re-identification under strict governance controls. Access to identifiable information is limited to authorised personnel for approved purposes only.
7.2. Secure Storage: All study data is stored in a highly secure, encrypted format on a professional cloud server located in Australia. This is like placing your information in a digital vault that requires multiple keys to open.
7.3. Restricted Access: Access to the identifying and deidentified data is strictly limited to authorised employees on the research team for approved purposes, as detailed in section 8. How will my information be used.
7.4. Confidential Reporting: No identifying images will be used in publications or presented at conferences. Any results from this study that are published or presented at conferences will be combined with data from all other participants and will be completely anonymous. It will be impossible for anyone to identify you from these reports.
- How will my information be used?
Your data will be used only for the following research purposes:
● analysis of eye-movement patterns
● development and validation of eye-movement algorithms
● scientific publication and presentation of aggregated findings
● internal research and quality assurance related to eye-movement measurement
- Who is running and paying for this project?
This study is sponsored by BrainEye (Neuro Optica Operations Pty Ltd). It is important that you know that the researchers conducting this study are employees of BrainEye and may hold a financial interest (shares) in the company.
This has been declared to the Human Research Ethics Committee, which has approved a plan to manage this conflict of interest.
- Who has reviewed this project?
The Bellberry Human Research Ethics Committee, Australia has reviewed and approved this study in accordance with the Australian National Statement on Ethical Conduct in Human Research (2025). Should you wish to discuss the study with someone not directly involved, particularly in relation to complaints or your rights as a participant, you may contact the Director of HREC Operations, Bellberry Limited on 08 8361 3222.
For any questions about the study itself, please contact the Principal Investigator, A/Prof Joanne Fielding, joanne.fielding@braineye.com.
- What happens if something goes wrong?
If you have any questions, concerns, or complaints about how the study is being conducted, you should first contact the research team.

- Can I access my results or the results of the study?
You will not receive individual test results from this study. The BrainEye test used in this project is experimental and not designed or validated for clinical or diagnostic use. Providing individual results could be misleading or cause unnecessary concern, as the meaning of any single result is not yet scientifically established.
Once the study is complete, a summary of the overall study findings will be prepared in clear language and made publicly available through academic publication and on the BrainEye website (www.braineye.com). You are welcome to access these results to learn about the general outcomes of the research.
