# CoWear-watch

This dataset contains only CoWear sessions marked `enabled` in the current
manual usage-mark file.

## Contents

- `data/processed/<date>/session_*/groundtruth/align.csv`: watch truth only.
- `data/processed/<date>/session_*/measure/align/watch/`: cropped watch
  accelerometer and gyroscope only.
- `manifest.csv`: one row per exported session.
- `splits/`: the original fixed CoWear session split filtered to exported rows.

Each session physically contains only the retained overlap segment. The crop is
the longest continuous intersection of watch truth, watch accelerometer, and
watch gyroscope. Continuous segments use `max_gap_s=0.200`. The
output `timestamp_ms` and `alignedTimestampMs` remain on the absolute aligned
clock; `time_s` and `alignedRelativeS` are rebased to the exported overlap
start.

The source data is not modified. The export used:

- enabled marks: `/home/zyshe/code/zyshe/insight/CoWear/reports/ricloc_watch_usage_marks.json`
- reviewer alignment results: `/home/zyshe/code/zyshe/insight/exports/watch_direct_relay_offset_preview/manual_alignment_results.json`
- enabled sessions found: `241`
- sessions exported: `241`
- sessions skipped for missing/invalid overlap: `0`
