This paper proposes a technique that allows novice users to retrieve motions using a mobile multi-touch device. A user first inputs a motion that he wants to obtain by manipulating a part of a character skeleton with multiple fingers. The proposed system automatically retrieves a couple of candidate motions from a motion database and visualizes them to the user. He selects one of them and manipulates a different part of the skeleton. Then the system generates a new motion by synthesizing multiple motion data retrieved through different parts of skeleton manipulations. By manipulating skeletons and retrieving motions iteratively, the user can obtain his desired motion in an efficient and easy manner. A pilot study has been conducted using the proposed system to clarify problems to be solved and functions to be improved.

“…These systems are restricted to the control of a single part of the body. Oshita [2012] applied a statistics-based IK (style-based IK [Grochow et al 2004]) to control the whole body of the character. However, the synthesized poses are limited to certain given example poses.…”

AbstractIn this paper, we propose an interactive motion control interface with hand manipulation. Using f ngers and hands, the user can simultaneously control a large number of degrees of freedom. Our interface is inspired by the control mechanism of a real puppet, which is suspended by about 10 strings attached to different parts of the puppet's body and the controller. The puppeteer can move the puppet in a variety of ways by holding and moving the controller with the right hand and manipulating the strings with the left hand. Our interface was designed based on this puppet mechanism. The character's pelvis translation and head/body rotation are controlled by the user's right hand, while the character's legs are controlled by the right hand f ngers. The character's arms are controlled by the user's left hand and f ngers. We have developed a method to control a character's motion based on this interface design. In this research, we used a depth-camera-based hand motion sensing device to implement our prototype. Using such a camera-based device obviates the need for the user to wear any device. However, the chosen technology has some limitations in hand motion sensing. Our method has been designed to work well even under these constraints. In this paper, we present our interface design and implementation, as well as the experimental results and a discussion thereof.

“…However, they are difficult to use for choreographic composition because most preview animations after editing sequences. Though motion control systems with touch inputs have recently been developed as real-time systems [7], it is difficult to compose creative and effective choreographies because their motions are limited.…”

SUMMARY This paper reports an assessment of the feasibility and the practicality of a creation support system for contemporary dance elearning. We developed a Body-part Motion Synthesis System (BMSS) that allows users to create choreographies by synthesizing body-part motions to increase the effect of learning contemporary dance choreography. Short created choreographies can be displayed as animation using 3DCG characters. The system targets students who are studying contemporary dance and is designed to promote the discovery learning of contemporary dance. We conducted a series of evaluation experiments for creating contemporary dance choreographies to verify the learning effectiveness of our system as a support system for discovery learning. As a consequence of experiments with 26 students who created contemporary dances, we verified that BMSS is a helpful creation training tool to discover new choreographic methods, new dance movements, and new awareness of their bodies.
