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 .)
