ABSTRACT
We describe a technique for displaying patterns that appear to move continuously without changing their positions. The method uses a quadrature pair of oriented filters to vary the local phase, giving the sensation of motion. We have used this technique in various computer graphic and scientific visualization applications.

Investigating motion sickness techniques for immersive virtual environments
PETRA '19: Proceedings of the 12th ACM International Conference on PErvasive Technologies Related to Assistive EnvironmentsMotion sickness is one of important issues in immersive virtual environments. In some cases it may last for hours after participation in the virtual experience. Reducing the amount of motion sickness in healthcare applications is of great importance. ...
Motion retrieval based on movement notation language: Motion Capture and Retrieval
CASA 2005With the increased availability of motion capture data, the volume of motion library grows so large that it is difficult for animators to manually browse the dataset to search desired motions for reuse. To address this issue, we implement a framework, ...
