Bouncing Balls of Exaggeration

A poster from VSS2019, finally about to submit the paper. Looking at animation, physics, and the impossible yet perceptually preferable exaggeration therein. Phillips, F., Schmidt, F., Noejovich, L., & Chakalos, G. (2018). Exploring the Uncanny Valley. Journal of Vision, 18(10),… Read More

Apples and Oranges

colorimeter device

A talk I gave at the Wolfram Technology Conference, 2019. In our “Computational Methods for Psychology and Neuroscience” course, we teach undergraduate students the fundamentals of computational thinking (as opposed to traditional “programming”) using a project-based approach. Over… Read More

Two recent submissions

So many things on the burner. First – The Veiled Virgin paper has been submitted. We didn’t put it on a preprint server yet, we’re trying to figure out what we want to do there. If you’d like… Read More

Temporal consequences of spatial acuity reduction

Space-time visual insanity. Some work I collaborated on concerning spatiotemporal vision. We have some very interesting findings hinted at in the ‘Puzzles’ section that I look forward to us getting out there. Temporal consequences of spatial acuity reduction… Read More

Effects of the Spatial Spectrum of Illumination on Material Perception

A little VSS 2019 fun with some old friends. Old as in length of time we’ve all known each other, not in geologic age. Like all good science, things changed a little between abstract submission and the actual… Read More

Objects, Materials, Exaggeration, and Perception

For a talk @ the ASU SciHub SciAPP Workshop on Science, the Arts & Possibilities in Perception. It is tempting to think of perception as some form of physical measurement. Indeed, animals seem to act as if they are… Read More

Why Does the Cortex Reorganize After Sensory Loss?


Investigating the Teleology of Cortical Reorganization A growing body of evidence demonstrates that the brain can reorganize dramatically following sensory loss. Although the existence of such neuroplastic crossmodal changes is not in doubt, the functional significance of these… Read More

Retina and LGN

A demonstration written in Mathematica to show the interaction of the retina and LGN on the sampling of image information from the eyes. You can play with the receptive field size to see how the whole “Hybrid Images”… Read More

VSS 2018 – Shape scission: causal segmentation of shape

Warts, cracks, causal shape segmentation. Research on shape perception usually focuses on the estimation of local surface geometry through cues like stereopsis, shading, or texture. Here, we argue that observers use these shape estimates to infer other object… Read More

VSS 2018 – Gravity and Ground Plane Geometry in Perspective Images

“The small things float to the top of… gravity” — Rickie Lee Jones Renaissance artists noticed that placing objects on a visible ground plane anchors them stably, making it easy to perceive their depth. Subsequently, they developed methods… Read More
