Virtual Reality Annotator: A Tool to Annotate Dancers in a Virtual Environment

摘要

In this paper we describe the Virtual Reality Annotator, a visualization tool that allows users to dynamically annotate dancers in a virtual reality environment. The current annotation types supported are sketches, speech-to-text, and highlighting. Each type of annotation can be applied to a bone or a set of bones of the skeleton data or a set of points of the point-cloud data. Using a wireless mouse, users can interact with the 3D objects of the virtual reality space, specifically a 3D menu that allows to choose the type of annotation and desired color as well as the skeleton and point cloud data. Examples of usage of this system using data from expert dancers are presented and discussed as well as suggestions for future work.
