Alexandre is currently finishing his PhD at ETH Zurich advised by Prof. Markus Gross, working simultaneously at the Computer Graphics Lab and at the industrial Disney Research Zurich lab. His thesis is focused on algorithmic and perceptual techniques leveraged to improve user experience with novel displays. In particular, his work touches on applied perception, 3D and multiview displays and HDR display. Before this, he completed his masters’ studies in Applied Mathematics at IMPA in Brazil, advised by Prof. Luiz Velho.

Novel display technologies give us the chance to enjoy content with additional realism. Some new display architectures are expected to soon become commercially available, in particular, autostereoscopic displays promise to deliver a glasses-free 3D experience. This freedom, however, comes with some significant limitations on the displays’ capabilities.
In this talk, I will present my recent work on Stereoscopic 3D. The methods discussed deal with a pervasive artifact that occurs when visualizing 3D content: the so-called “cardboarding” effect, where objects appear flat due to depth compression. Results of perceptual experiments performed to measure cardboarding, as well as computational techniques to avoid it using disparity remapping and other stereo cues will be presented.
