CEHAR reproducibility package: From wearable sensing to environmental decision support

This repository contains the reproducibility materials for the CEHAR study “From wearable sensing to environmental decision support: Mobility-context recovery and downstream decision robustness.”CEHAR links wearable sensing to environmental decision support through a multi-stage analytical chain comprising body-activity and carrier-context inference, environmental-information interface selection, feasibility filtering, opportunity-set construction, and preference-sensitive decision analysis.The repository contains 140 Phase-I IMU recordings and 220 Phase-II IMU recordings, together with validated metadata and trip-disjoint split manifests. For the Phase-II audio branch, raw environmental recordings are not publicly distributed because they may contain incidental speech and third-party copyrighted background audio. Instead, the repository provides a public-safe recording-level dataset containing 48 handcrafted acoustic descriptors for the 169 carrier-valid recordings.The repository also contains recovered research code and model configurations where available, prediction and statistical artifacts, carrier-interface consequence data, and the frozen UK reference workbook used for the downstream environmental decision analysis.The public package was assembled from preserved project evidence without retraining models or regenerating the reported machine-learning results.
