  The human visual system uses numerous cues for depth perception, including
disparity, accommodation, motion parallax and occlusion. It is incumbent upon
virtual-reality displays to satisfy these cues to provide an immersive user
experience. Multifocal displays, one of the classic approaches to satisfy the
accommodation cue, place virtual content at multiple focal planes, each at a di
erent depth. However, the content on focal planes close to the eye do not
occlude those farther away; this deteriorates the occlusion cue as well as
reduces contrast at depth discontinuities due to leakage of the defocus blur.
This paper enables occlusion-aware multifocal displays using a novel ConeTilt
operator that provides an additional degree of freedom -- tilting the light
cone emitted at each pixel of the display panel. We show that, for scenes with
relatively simple occlusion con gurations, tilting the light cones provides the
same e ect as physical occlusion. We demonstrate that ConeTilt can be easily
implemented by a phase-only spatial light modulator. Using a lab prototype, we
show results that demonstrate the presence of occlusion cues and the increased
contrast of the display at depth edges.
