We present TRAFA, a real-time predictive feedback system for procedural tasks that intervenes before errors are committed. TRAFA operationalizes predictive feedback through a Track-Forecast-Act framework that tracks hand and object state, forecasts user motion conditioned on scene context, and triggers feedback when a predicted action is likely to violate task constraints. We instantiate this pipeline in a sequential assembly setting and e","authors_text":"Dominik Bach, Fatemeh Jabbari, Juergen Gall, Lars Doorenbos, Marius Bock, Sassan Mokhtar","cross_cats":["cs.AI"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.HC","submitted_at":"2026-05-23T11:29:15Z","title":"TRAFA: Anticipating User Actions to Reduce Errors in Procedural Tasks with Predictive Feedback"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2605.24526","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":"sha256:1bca7aa7673e10dedeac2f459d9321626502cf70fa53473ce4540e8cda825687","target":"record","created_at":"2026-05-26T01:03:44Z","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":"1630234dfe3e687bfab77e6f67b888a21d0abce5865aaf1633bdcb653c98fe70","cross_cats_sorted":["cs.AI"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.HC","submitted_at":"2026-05-23T11:29:15Z","title_canon_sha256":"7b1c8f4232d79734fd3673efb605657cbf43874386413562e5fb366edbbf44fb"},"schema_version":"1.0","source":{"id":"2605.24526","kind":"arxiv","version":1}},"canonical_sha256":"8545e2b98f97ef0d50f4e24eb9ba2aaa826778063720d500e44d55a70991aa47","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"8545e2b98f97ef0d50f4e24eb9ba2aaa826778063720d500e44d55a70991aa47","first_computed_at":"2026-05-26T01:03:44.513941Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-26T01:03:44.513941Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"tEXVzcEIIi+1uu1NCUWLRcJtx87JOFUqZvJ4ka7G5JnrS6RepVVPGzqUZYLizXqj3ciX/3TioHmZucPTvtu2DA==","signature_status":"signed_v1","signed_at":"2026-05-26T01:03:44.514773Z","signed_message":"canonical_sha256_bytes"},"source_id":"2605.24526","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:1bca7aa7673e10dedeac2f459d9321626502cf70fa53473ce4540e8cda825687","sha256:7491c56e20e0c456596f29c806f853e28c661a80a5a80006996150728356e099"],"state_sha256":"262178cb1fb21d48eed2789f85071e8b9b87b5d89cef6ae4a74202f829e6be54"}
