@grant-rogers I am aware of the User Presence State and I have used that, but it does not work if there is no configured calibration. You previously mentioned ‘at the minimum detect the ‘presence’ of a user through the ‘are eyes found’ function (documented within the EyeX SDK manual – Example: Engine states)’ which I thought was something different that I have not been able to find. I thought I may be able to use that without a calibration being done. Maybe I misunderstood what you meant.
