Outline

This paper raises the possibility that VR and virtual spaces will become an important part of our daily lives due to the advancement of computer hardware, sensor technology, and artificial intelligence, and focuses on eye-tracking technology in VR environments. Eye-tracking can enhance the understanding of users’ visual attention and cognitive processes as well as hands-free interaction, but it also carries the risk of personal information leakage when combined with presented stimulus information. Therefore, this paper reviews major studies on eye-tracking, VR, and privacy from 2012 to 2022. In the eye-tracking section, the entire pipeline from pupil detection and gaze estimation to data analysis is covered, and in terms of privacy and security, the focus is on eye-based authentication and computational methods to protect the privacy of individuals and eye-tracking data. Based on this, three major research directions focusing on privacy issues are presented, and an extensive literature review on the potential of eye-tracking in VR and privacy issues is provided.

Takeaways, Limitations

Takeaways:
It presents the possibilities and applications of eye tracking technology in VR environments.
Provides an in-depth understanding of privacy issues in eye tracking data.
We present computational methods and research directions for protecting eye-tracking data privacy.
It suggests the potential for development of child-based authentication technology.
Limitations:
It only covers research from 2012 to 2022, so it may not fully reflect recent trends.
The three proposed research directions are presented in general terms without specific methodologies or experimental designs.
There may be a lack of consideration for differences in various VR environments and eye tracking systems.
There may be a lack of concrete analysis of the effectiveness and limitations of privacy protection technologies.
