Relationship descriptors for interactive motion adaptation

Abstract: This paper presents an interactive motion adaptation scheme for close interactions between skeletal characters and mesh structures, such as moving through restricted environments, and manipulating objects. This is achieved through a new spatial relationship-based representation, which describes the kinematics of the body parts by the weighted sum of translation vectors relative to points selectively sampled over the surfaces of the mesh structures. In contrast to previous discrete representations that either o… Show more

“…The result generated by our method (Figure 7 (c)) shows the body parts are coordinated such as the knees) to keep the COP to be lying over the support polygon. The results highlight the advantage of our proposed method over another real-time motion adaptation approach [Al-Asqhar et al 2013] in which physical constraints can be enforced in our method to produce physically feasible motions. The readers are referred to the attached video demo to evaluate the quality of the retargeted motions.…”

“…However, existing methods except either cannot handle close interactions well, or even they do, their convergences is either slow (such as [Ho et al 2010]) or have issues handling physical constraints (such as [Al-Asqhar et al 2013]) which can be important for some applications.…”

“…5 we show the application of motion editing using our technique. We synthesize some locomotion using animator supplied data and use Spatial Descriptors [Al-Asqhar et al 2013] to edit the result. This advanced motion editing technique expresses an animation in terms of its environment which allows an animation to be naturally deformed to follow some terrain.…”

“…For example our work could be used in conjunction with Motion Layers [Lee and Shin 2001], Motion Warping [Witkin and Popovic 1995], Full-Body Inverse Kinematics [Yamane and Nakamura 2003], and Relationship Descriptors [Al-Asqhar et al 2013]. Because our approach is in real-time it allows for a tight feedback loop between these motion tools and animator edits.…”

“…et al [2010], which is based on a new structure called Interaction Mesh. This new structure is particularly efficiently to represent implicit spatial relationships between body parts, and has also been extended to account for relationships between human motions and its environment [Al-Asqhar et al 2013;Ho and Shum 2013].…”
