Previously, two main settings existed for two-character interaction generation: (1) generating one's motions based on the counterpart's complete motion sequence, and (2) jointly generating two-character motions based on specific conditions. We argue that these settings fail to model the process of real-life two-character interactions, where humans will react to their counterparts in real time and act as independent individuals. In contrast, we propose an online reaction policy, called Ready-to-React, to generate the","authors_text":"Huaijin Pi, Hujun Bao, Qing Shuai, Ruizhen Hu, Sida Peng, Xiaowei Zhou, Yujun Shen, Zhi Cen","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CV","submitted_at":"2025-02-27T18:40:30Z","title":"Ready-to-React: Online Reaction Policy for Two-Character Interaction Generation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2502.20370","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:38e0734b8cc53ec59b9ceb6b289aa8184b792b644245ea324d352357dcf7e710","target":"record","created_at":"2026-07-05T10:21:13Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"a07b459ae716d26c75c577ca4c858d8c3bce5393bb1a7ca97a0bb0c4a604e762","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CV","submitted_at":"2025-02-27T18:40:30Z","title_canon_sha256":"3d72dc68da98a7552e37d7e12a70c34c8cd758791f1921a60806f8ab79d8c848"},"schema_version":"1.0","source":{"id":"2502.20370","kind":"arxiv","version":1}},"canonical_sha256":"a42cd9fdc0423f2aba996cb9bbefc8e3f53ccc65af1d611f6f87da7a315b4d7e","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a42cd9fdc0423f2aba996cb9bbefc8e3f53ccc65af1d611f6f87da7a315b4d7e","first_computed_at":"2026-07-05T10:21:13.836872Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T10:21:13.836872Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"eatA4plO2oWQO9yPGgi9sVUEjVdLA5LFSZFWY/YIK5oRiJBwkztcNxQusrWCvfJdSP1DkzLQplOBG40MNyhNAQ==","signature_status":"signed_v1","signed_at":"2026-07-05T10:21:13.837375Z","signed_message":"canonical_sha256_bytes"},"source_id":"2502.20370","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:38e0734b8cc53ec59b9ceb6b289aa8184b792b644245ea324d352357dcf7e710","sha256:da0e4f455077eb12b8025259d86bb9ff6b9fad622cac19b7c1a4c3fc472c2db4"],"state_sha256":"05d769093646c07e1946ba404e6759db5d6ff8c46175f16760829202bb31801b"}
