A Method for Supporting Recognition of Remote Bodily Gestures
Katsuhiko Kaji, Naomi Yamashita, Keiji Hirata · Institutional Repositories DataBase (IRDB) · 2010
The 3D structure of body movements and gestures becomes distorted when a sequence of those movements and gestures is captured by multiple cameras and displayed on multiple 2D screens at a remote site. This increases the chances of remote people losing sight of those gestures, possibly making it difficult to understand the meaning intended by the gestures. To alleviate such problems, we propose a visual augmentation technique, called ``remote lag,'' that applies the concept of telepointer traces to the bodily gestures made in a videoconferencing system. Remote lag is a visual effect that overlays a user's past motion image onto his/her real-time image. Author Keywords Remote lag, videoconferencing system, lagged image, optical flow.
