Can computers auto adjust screen brightness via your pupil constriction?


Wouldn't this be more convenient than having to constantly adjust brightness manually?

I think we solved this with ambient light sensors like, a decade ago.

Other than needing a sensor there may be an interesting feedback effect between the light from the monitor and pupil size.

Also between non-light related pupil size changes. On an online call you may see some emotional reaction by how the lighting of a face changes.

Only if they had some form of pupil constriction sensor. Without a constriction sensor the computer has no way to know how constricted your pupils are.

Or you could take a dose from two separate classes of drugs to adjust screen brightness?
