Perceiving Object Shape from Specular Highlight Deformation, Boundary Contour Deformation, and Active Haptic Manipulation
Haptic and visual ‘contours’ It is well known that motion facilitates the visual perception of solid object shape, particularly when surface texture or other identifiable features (e.g., corners) are present. Conventional models of structure-from-motion require the presence of… Read More
Haptic shape discrimination and interhemispheric communication
Touching. In three experiments participants haptically discriminated object shape using unimanual (single hand explored two objects) and bimanual exploration (both hands were used, but each hand, left or right, explored a separate object). Such haptic exploration (one versus… Read More
Creating noisy stimuli
So much noise. A method for creating a variety of pseudo-random `noisy’ stimuli that possess several useful statistical and phenomenal features for psychophysical experimentation is outlined. These stimuli are derived from a pseudo-periodic function known as multidimensional noise…. Read More
Perceptual representation of visible surfaces
What is a surface, anyway? Two experiments are reported in which we examined the ability of observers to identify landmarks on surfaces from different vantage points. In Experiment 1, observers were asked to mark the local maxima and… Read More
Mathematica / Wolfram Language support for Microsoft VSCode
I whipped up some simple syntax support for Mathematica / Wolfram Language in Microsoft’s VSCode. Grab it here: marketplace.visualstudio.com/items?itemName=flipphillips.wolfram-language.
Travels in the uncanny valley
Here’s a screencast of my talk at the Rochester Institute of Technology Symposium on VR/AR Technology. It is from 3 December and a little low-key, so drink a little coffee before you start watching so you don’t fall… Read More
Enhancing research with Plenary Labs
A new pub with some good friends on the impending doom of science funding and what to do about it. Authored well before the new administration was a gleam in our collective eyes. Citation: Pawan Sinha, Peter… Read More
Fuzzy Logic package for Mathematica
I was working on a project in Gießen last week and needed some code I wrote back in the late 1980’s / early 1990’s. Sadly, this is no replacement for the super cool FuzzyLogic Mathematica package (RIP). It… Read More
Glaven Object Files
I’ve posted the Glaven STL and OBJ object files in the Software, Data & Geometry section. Go have a look and let me know if you use them or even download them for that matter.
