{"doi":"10.1145/3769102.3774708","title":"Mobile Edge Testbed for Driving Behavior Data Collection and Cognitive Impairment Analysis","abstract":"Studying cognitive impairment and its impact on driving behaviors is crucial for enhancing public safety. To facilitate cognitive impairment studies, we devise a testbed for realworld driving data collection using ubiquitous mobile edge devices (i.e., smartphones) [4]. Toward this end, we develop an application for autonomous data collection using smartphones. To enable robust data collection in real-world driving scenarios, we design a coordinate alignment method that automatically aligns the smartphone's coordinate system with the vehicle's by continuously detecting stationary and straight-line acceleration periods. We also design a two-step segmentation algorithm that first utilizes gyroscope readings to segment rotation-based behaviors (e.g., turning) and then employs accelerometer data to segment non-rotation-based behaviors (e.g., braking). The processed data is then uploaded to a cloud server through WiFi connections for further analysis.","journal":null,"year":2025,"id":584004,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":0,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.8972,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2025-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":1496489,"name":"Bin Han","orcid":"0009-0001-1672-0358","position":1,"is_corresponding":false},{"id":1496490,"name":"Cong Shi","orcid":"0000-0002-7599-202X","position":2,"is_corresponding":false},{"id":1089743,"name":"Yan Wang","orcid":"0000-0002-3984-6973","position":3,"is_corresponding":false},{"id":340320,"name":"Tammy Chung","orcid":"0000-0002-1527-2792","position":4,"is_corresponding":false},{"id":1354255,"name":"Yingying Chen","orcid":"0000-0002-3994-766X","position":5,"is_corresponding":false},{"id":1466158,"name":"Honglu Li","orcid":"0000-0003-0194-7979","position":0,"is_corresponding":true}],"reference_count":4,"raw_metadata":null,"created_at":"2026-07-19T02:59:07.970345Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
