In this paper, the problem of detecting whether the driver is using the phone during a trip is addressed. To do this, high-frequency data from the triaxial inertial measurement unit (IMU) integrated in almost all modern phone is processed without relying on external inputs so as to provide a self-contained approach. By resorting to a frequency-domain analysis, it is possible to extract from the raw signals the useful information needed to detect when the driver","authors_text":"Mara Tanelli, Sergio Savaresi, Silvia Strada, Simone Gelmini, Vincenzo Biase","cross_cats":["cs.LG","eess.SP"],"headline":"","license":"http://creativecommons.org/licenses/by-nc-sa/4.0/","primary_cat":"cs.HC","submitted_at":"2018-04-06T11:42:06Z","title":"Analysis and development of a novel algorithm for the in-vehicle hand-usage of a smartphone"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1804.02960","kind":"arxiv","version":2},"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":"sha256:3293d9a171ece5c55586fa5678cac2a35e87aa72490f294bd9be335e10343740","target":"record","created_at":"2026-05-18T00:06:50Z","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":"37e6ffd2d467ad7f83e86e13a2fe8334999aad33b087537dbea844861e373c5f","cross_cats_sorted":["cs.LG","eess.SP"],"license":"http://creativecommons.org/licenses/by-nc-sa/4.0/","primary_cat":"cs.HC","submitted_at":"2018-04-06T11:42:06Z","title_canon_sha256":"3a00d3bcf770167d5dea135aa9fbd7a12bbaf532358485df7dba9401d5c147ce"},"schema_version":"1.0","source":{"id":"1804.02960","kind":"arxiv","version":2}},"canonical_sha256":"7b5e9c6c1ba5f77c47b77fb2b36fc597886625f05811b8333db1a3e69b45f89e","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"7b5e9c6c1ba5f77c47b77fb2b36fc597886625f05811b8333db1a3e69b45f89e","first_computed_at":"2026-05-18T00:06:50.772516Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:06:50.772516Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"rp0gtxUJmIXmAbxNSORtfSuF44cW3EWJXftciGIsLUfBPAWYXnFJ4Lgwd1Fquuo70dQDYfoKbMQXgMuyTVGBCg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:06:50.773156Z","signed_message":"canonical_sha256_bytes"},"source_id":"1804.02960","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:3293d9a171ece5c55586fa5678cac2a35e87aa72490f294bd9be335e10343740","sha256:3135767429098d057b7a3c9c30eed7411fbb6dffbafc5dbb0d21ef8415035980"],"state_sha256":"f60312bfd830c848979cba39e26bcf0da718fd5b5852a9c9f509100f395c1fbb"}
