| # RawHandPip Sample | |
| This directory is a complete-episode sample of the DeskTaskTac RawHand pipeline. | |
| RawHand episodes use image-based hand keypoint detection and multi-view triangulation to recover hand state, together with tactile glove readings. This subset uses the same per-frame schema as `../AprilTagPip`; see `../README.md` for the DeskTaskTac field dictionary. | |
| ## Summary | |
| | item | value | | |
| | --- | ---: | | |
| | episodes | 10 | | |
| | frames | 10,974 | | |
| | task entries | 10 | | |
| | top-view videos | 10 | | |
| Episode indices and video paths are local to this subset and align with the files under `data/` and `videos/video.top_view/`. | |
| ## Layout | |
| - `data/episode_*.parquet`: frame-level episode data. | |
| - `videos/video.top_view/episode_*.mp4`: top-view MP4 videos. | |
| - `meta/features.json`: 38-field DeskTaskTac per-frame schema. | |
| - `meta/dataset_info.json`: dataset-level metadata, modality mapping, and coordinate systems. | |
| - `meta/episodes.parquet`: episode-level metadata. RawHand includes additional raw-hand processing fields. | |
| - `meta/tasks.jsonl`: task id to task-name mapping. | |
| - `meta/episode_records/*.json`: per-episode metadata records. | |
| ## Loading Notes | |
| - Resolve paths in `video.top_view` relative to this directory. | |
| - Treat `state.eef_*` and `state.left_eef_*` as right/left hand wrist or anchor poses in the first-person OpenCV camera frame. | |
| - `timestamp` is episode-relative seconds; `timestamp_ms` preserves the captured millisecond timeline. | |
| - `manus_frame_index` is commonly `-1` in RawHand episodes because this pipeline does not rely on a Manus/MoCap source in the same way as AprilTag episodes. | |
