An editable interface for motion data retrieval based on Labanotation

In this paper, we design a natural interface based on Labanotation, a 2-D graphical editable movement symbols, to describe the desired motion as input. A weighted directed hierarchical graph is built. Graph edge represents a unique motion from one pose to another pose and indexes by Labanotation symbols for retrieval. A motion metric is proposed to measure similarity between two motions based on Laban Movement Analysis (LMA) on the middle level. Experiments show that the presented system is easy to use and have a high quality of retrieval results. This interface can be easily applied on the mobile devices.
