A Reusable Model for Emotional Biped Walk-Cycle Animation with Implicit Retargeting

چکیده
This paper presents a reusable model for rapid animation of the walkcycle of virtual biped characters, with implicit retargeting of motion capture to any character, regardless of dimensions. Despite modern software continuously improving the quality of automatic assistance, the process of animating a biped character still requires substantial manual intervention. Our research contributes to this field by creating a theoretical model for emotional character walking, defining a series of proportional variables which can be changed to create different emotional walk cycles. We used motion capture data to assign real-world values to these variables, which are then used to procedurally create ‘emotional’ walk cycles. Due to the fact that we avoid fixed values and work solely with proportions, the system implicitly retargets the data to any biped body shape, regardless of the size and structure of the skeleton.

متن کاملHumanoid Gait Synthesis with Moving Single Support Zmp Trajecories
The control of a biped humanoid is a difficult task due to the hard-to-stabilize dynamics. Walking reference trajectory generation is a key problem. Reference generation techniques with the so-called Linear Inverted Pendulum Model (LIPM) are reported. Improved versions of the LIPM based reference generation are obtained by applying the Zero Moment Point (ZMP) Criterion, widely employed in the s...
متن کاملBiped Walk Learning Through Playback and Corrective Demonstration
Developing a robust, flexible, closed-loop walking algorithm for a humanoid robot is a challenging task due to the complex dynamics of the general biped walk. Common analytical approaches to biped walk use simplified models of the physical reality. Such approaches are partially successful as they lead to failures of the robot walk in terms of unavoidable falls. Instead of further refining the a...

The focus of studies in the field of passive walking has often been on straight walking, while less attention has been paid to the field of turning motions. In this paper, the passive motions of a finite width rimless wheel as the simplest 3D model of passive biped walkers was investigated with a focus on turning motions. For this purpose, the hybrid model of the system consisting of continuous...
