- Perception of collisions between virtual characters

Version of Record online: 20 SEP 2016 | DOI: 10.1002/cav.1728
This paper investigates the accuracy of human observers in recognizing collisions between virtual characters. We show the result of two user studies, where participants classify scenarios as “colliding” or “not colliding.” On average respondents correctly classified 72% (static) and 68% (animated) of the scenarios. The maximum uncertainty was observed when the characters are overlapping slightly and that there is a significant bias towards answering “not colliding.” We also discuss differences in bias in the recognition of upper-and lower-body collisions.

We propose a method to generate hand motion from full-body motion. We train a support vector machine from a number of full-body motions with manually specified hand-pose keyframes in order to choose one of four key hand poses based on the full-body pose. We realize smooth transitions between key hand poses and add small movements of fingers for generating plausible hand motions.

Digital storytelling is a powerful pedagogical tool for young children. In this paper, we design an immersive storytelling environment that allows multiple players to use naturally interactive hand gestures to manipulate virtual puppetry for assisting narration. A set of multimodal interaction techniques is presented for a hybrid user interface that integrates existing 3D visualization and interaction devices including head-mounted displays and depth motion sensor. Experiments show great potential to stimulate young children's learning abilities through collaboration tasks.
- Anticipatory balance control and dimension reduction
Amir H. Rabbani, Michiel van de Panne and Paul G. Kry
Version of Record online: 13 JUL 2016 | DOI: 10.1002/cav.1726
Learned center-of-mass reference trajectories enable anticipatory control for a variety of tasks, including (from left to right top to bottom): fast changes of pose; punching; catching and lifting; pushing; hitting and pulling.
