Privacy Implications of Eye Tracking in Mixed Reality
It addresses privacy concerns for users and bystanders in Mixed Reality, focusing on an incremental application of existing tracking techniques.
The paper examines the privacy challenges posed by eye and gaze tracking technologies as they become default features in Mixed Reality devices, highlighting the need to define and defend privacy in this new context.
Mixed Reality (MR) devices require a world with always-on sensors and real-time processing applied to their outputs. We have grappled with some of the ethical concerns presented by this scenario, such as bystander privacy issues with smartphones and cameras. However, MR technologies demand that we define and defend privacy in this new paradigm. This paper focuses on the challenges presented by eye tracking and gaze tracking, techniques that have commonly been deployed in the HCI community for years but are now being integrated into MR devices by default.
