Larger efforts at trying to determine emotions or mental health through things like social media use, or iPhone or iWatch use, have had very questionable results, and any claims of being able to detect emotions reliably are probably false.
Larger efforts to determine emotions or mental health through social media or devices like the iPhone or Apple Watch have produced iffy results, and any claims of reliably detecting emotions are probably false.
