Using Pupil Reflection in Smartphone Camera Selfies
Researchers are using the reflection of the smartphone in the pupils of faces taken as selfies to infer information about how the phone is being used:
For now, the research is focusing on six different ways a user can hold a device like a smartphone: with both hands, just the left, or just the right in portrait mode, and the same options in horizontal mode.
It’s not a lot of information, but it’s a start. (It’ll be a while before we can reproduce these results from Blade Runner.)
