# TactileEval Dataset

TactileEval decomposes tactile-graphic quality into five BANA-aligned quality
dimensions (view, parts, background, texture, line quality) across six object
families, yielding 30 task families and 14,095 option-level annotations. Each
record corresponds to a natural photo / tactile drawing pair and a specific
quality option with majority-vote label, vote counts, and provenance metadata.

## Repository layout

```
images/
  <Family>/<Object>/<Natural|Tactile>/*.{jpg,png}
processed/
  records_full.jsonl
  splits/{train,val,test}.jsonl
  family_splits/F{1..6}/{train,val,test}.jsonl
  dataset_summary.{csv,json}
```

JSONL fields:

| Field | Description |
|-------|-------------|
| `pair_id` | `NaturalRel::TactileRel` identifier |
| `task_family` | Task code (e.g., F1QL) |
| `option_id` | Option identifier (e.g., `too_thick`) |
| `option_description` | Plain-language description |
| `natural_image`, `tactile_image` | Paths relative to `images/` |
| `votes_total`, `positives`, `negatives` | Vote stats |
| `label` | Majority label (0/1) |
| `vote_fraction` | positives / total |
| `status_counts` | counts of approved/submitted ballots |

## Splits

- `splits/train.jsonl` (11,348 records)
- `splits/val.jsonl` (1,341 records)
- `splits/test.jsonl` (1,406 records)

`family_splits/` mirrors these splits per object family.

## Usage

```python
from datasets import load_dataset

ds = load_dataset("Adnank1998/TactileEval", name="full", split="train")
family = load_dataset("Adnank1998/TactileEval", name="family_f1", split="train")
example = ds[0]
print(example["natural_image"], example["label"])
```

Images are stored under `images/`; join the relative path returned in
`natural_image`/`tactile_image` with the local dataset root to load the files.

Available configurations:
- `full`: All families (default).
- `family_f1` through `family_f6`: Per-family subsets matching the paper splits.

Each split lives in `processed/`, enabling the Hugging Face dataset viewer via
the bundled `dataset_infos.json`.

Available configurations:
- `full`: All families (default).
- `family_f1` … `family_f6`: Per-family subsets matching the paper splits.

Each split lives in `processed/`, so the Hugging Face dataset viewer can load the files directly via the bundled `dataset_infos.json`.
