Interaction
Plane-Shape Perception Using Point-Contact Type Force Feedback Device

Although haptic rendering requires a high control rate (~kHz), modeling and simulation processes are much slower and can provide only discrete shape information. Haptic interpolation of such discrete shape fragments is thus vital. Our experiment on haptic thresholds in static plane-shape recognition gives useful results for interpolation algorithm design.

A Psychophysical Study on Human Perception of Surface

Human perception of surface reflectance properties is psychophysically examined, and the experimental results suggest that the perception is based on image features rather than the reflectance distribution itself.

The Analysis and Visualization of Metamorphopsia through 3D Scene Regeneration

Metamorphopsia is a vision disorder that transforms one's environment into an Escher-like world of fluctuating shapes and double vision. MAVES quantifies and visualizes metamorphopsia through 2D warping and 3D animation.

The Use of Distortion for Special Venue Films

This sketch discussed three Rhythm & Hues projects that used image-distortion for special venue ride films, so that when the animation is projected, it appears undistorted to the viewer.
