Crucially, the display surface and

Crucially, the display surface and display driving electronics are effectively
decoupled, which allows arbitrary curved display surfaces
to be designedand iterated without modifying the conventional planar image source. In addition, the same optical
elements can also direct light from the display surface to an
image sensor allowing position and proximity of user hand
to be tracked. Touch, proximity and position sensitivity of
PAPILLON is an important contribution of this work.
