However, the method for transitioning inter active motions considering the character's diverse mesh shape has yet to b e studied. We propose a Spatio Cooperative Transformer (SCT) to retarget t he interacting motions of two characters having arbitrary mesh topologies. SCT predicts residual of root position and joint rotations considering th e shape difference between the source and target of interacting characters . In addition, we introduce an anchor loss function for SCT to maintain ge ometric distance between interacting characters from source to target char acters. We also propose a motion augmentation method with deformation-base d adaptation to prepare a source-target paired dataset with identical mesh topologies. In experiments, our method shows higher accuracy for semantic preservation and lower artifacts of inter-penetration between interacting characters for the unseen character and motion than the baselines. Moreov er, we conduct a user evaluation across various shapes of characters, span ning low-to-high interaction levels to show better semantic preservation o f our method compared to previous works.\n\nRegistration Category: Full Ac cess, Full Access Supporter\n\nLanguage Format: English Language\n\nSessio n Chair: Jungdam Won (Seoul National University) URL:https://asia.siggraph.org/2024/program/?id=papers_778&sess=sess117 END:VEVENT END:VCALENDAR
