Kinesthetics of dancing vs. cyclical movements

In this work, we analyzed and compared two patterns of movement according to a rhythmic signal (dancing vs. cyclical rhyth- mic movements) to create a more natural virtual dancing partner with haptic feedback. We observed linear movements to reduce …

The relation between disparity and velocity signals of rigidly moving objects constrains depth order perception

In two experiments, observers were asked to judge the relative depth of a probe and one or two flanker dots. In Experiment 1, we found that such judgments were influenced by the properties of adjacent image regions, that is, by the amount of angular …

Spatial integration in structure from motion

In three experiments we investigated whether the perception of 3D structure from the optic-flow involves a process of spatial integration. The observer's task was to judge the 3D orientation of local velocity field patches. In two conditions, the …

Short-term temporal recruitment in structure from motion

Temporal integration was investigated in the minimal conditions necessary to perform a structure-from-motion (SFM) task. Observers were asked to discriminate three-dimensional (3D) surface orientations in conditions in which the stimulus displays …

Illusory 3-D rotation induced by dynamic image shading

Observers' perceptions of the three-dimensional structure of smoothly curved surfaces defined by patterns of image shading were investigated under varying conditions of illumination. In five experiments, observers judged the global orientation and …
