In addition to presenting classical signal quality metrics—spatial accuracy, spatial precision and linearity—in ideal settings, we also study the impact of background luminance and headset slippage on device performance. We additionally present a user-centered analysis of eye tracking signal quality, where we highlight the potential differences in user experience as a function of device performance. This work contributes to a growing understanding of eye tracking signal quality in virtual reality headsets, where the performance of applications such as gaze-based interaction, foveated rendering, and social gaze are directly dependent on the quality of eye tracking signal.Text14 pages1 file (.pdf)enAttribution-NonCommercial-ShareAlike 3.0 United Stateseye trackingsignal qualitymeta quest proPreprint
