Today I realized that the #android camera app shifts seamlessly into an #assistant mode when it detects that it is near-transverse (parallel to floor) or near-level when coronal (parallel to wall): it adds custom reticles to help you get it just right. It also has a little haptic bump when you get it perfect. Now if only you could tell it to automatically take when perfect or respond to voice—having to double-press side buttons often unlevels it again. #ModesOfInteraction #ux
