Motion-sphere is a technique to visualize a human motion. The Motion-sphere can express subtle motion accurately, thereby it can be an efficient tool for gesture recognition system. The system enables the human-machine interface. The current work proposes a gesture recognition system using a series of motion data as a trajectory, on a Motion-sphere. Unlike the use of skeletal or position data for motion recognition, the proposed work uses the trajectory data. In this study, we compare the existing gesture recognition system that uses 3D positions against the proposed Motion-sphere based system. In the 3D position data-base, Dynamic Time Warping(DTW) algorithm is applied to compare the sequence of motion by extracting keyframes. In 3D trajectory data, Levenshtein Distance on Trajectories(LDT) algorithm is used and no separate keyframe extraction is followed. The results of the experiment show that the Motion-sphere based system exhibits higher accuracy due to quantification of subtle body motions.

With the expeditious advancements in Motion Capture (mocap) systems, maneuvering motion data for extensive usage is a challenging task. In this paper, we propose a comprehensive technique to author new motion or modify existing motion data by considering vital motion parameters. Motion data is a collection of motion frames where each frame corresponds to the position and orientation of bone segments. Unit motion is a sequence of motion between any two keyframes captured either using a mocap system or authored using a conventional motion authoring tool. We consider a predefined set of unit motions to author precise human movements. Unit motion editing modifies swing, twist, and speed parameters to generate a consistent, accurate, and meaningful motion. The resultant unit motions are integrated into a meaningful sequence to synthesize various desired human movements. We demonstrate our work using a set of basic unit yoga motions to author meticulous and complete yoga movements.
