I've had the idea for a long time to create some kind of mobile phone case that had some kind of positional sensor in it. If you slumped into iPosture, this means your phone is closer to horizontal on its face. If you're lifting your phone up to use it at eye level, it's going to be vertical. Maybe the case could even blank out the screen when it passed a certain degree of horizontality.
As a long time massage therapist - I've seen the effects of iPosture for a long time. And even when I KNOW better, I still sometimes find myself in that position.
Great post. And I'm with you on that mission, sista.
