Kryven, Marta, and William Cowan. Why Magic Works? Attentional Blink With Moving Stimuli International Conference on Perceptual Organization, York University Centre for Vision Research , 2015. Conference poster
Stage magicians know how to hide actions in plain sight. One method is to perform two actions in succession so that the audience attends to the first action, but misses the second. For example, a magician waves a magic wand and immediately drops a coin missed by the spectator. Such a technique resembles attentional blink, a phenomenon when the detection of the second of the two visual targets presented in close succession is impaired. We show that attentional blink may be used to create magic effects.

Kryven, Marta, and William Cowan. What does water look like? Proceedings of the Workshop on Computational Aesthetics, 2014. link
PDF
Computational Aesthetics is a leading conference in computer-aided and computer-generated art and design. This paper describes a series of psychophysical studies of perception of water. We examined how water may be represented in vision, which visual features contribute to recognizing water and whether the concept of water, a substance that does not assume a steady shape, might be represented by a canonical view. For a brief idea of what we did see presentation slides

Kryven, Marta, and Elodie Fourquet. Generating knitting patterns from a sketch: a CSP approach. Proceedings of the Symposium on Computational Aesthetics, 2013.
This paper describes a software system I built to rasterize drawings into knitting patterns. The rasterizer solves a search problem on the space of all raster images such that the solution is perceptually close to the original drawing and free of visual artifacts.
