HoloFlex: A Flexible Holographic Smartphone with Bend Input

We present HoloFlex, a 3D flexible smartphone featuring a lightfield display with 16,640 microlenses. HoloFlex renders "holographic" images providing motion parallax and stereoscopy to multiple users with a resolution of 160x104 pixels, without glasses. Images are rendered into 12-pixel wide circular blocks, each of which displays a fish-eye view of the 3D scene as observed from a particular viewpoint. The lenses distribute each pixel in a direction that preserves the angular information of light rays. Touch input allows for x,y input, while bend sensors allow users to control the z dimension, by squeezing the display.
