Ask HN: Can computers auto adjust screen brightness via your pupil constriction?
Wouldn't this be more convenient than having to constantly adjust brightness manually?
- pwg 2y ago> Can computers auto adjust screen brightness via your pupil constriction? 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.
- talldayo 2y agoI think we solved this with ambient light sensors like, a decade ago.
- amichail 2y agoIt helps but it doesn't completely solve it.
- ano-ther 2y agoOther 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.
