CaptainCook4D: A Dataset for Understanding Errors in Procedural Activities

(This page is under continuous update and construction.)

DISCLAIMER: The proposed data splits showcase the ways in which our dataset can be used. We do not claim that these splits are the best or the only way to use the dataset. We encourage the community to explore other ways to use the dataset and share their findings with us.

Annotation JSONs

---

File: step_idx_description.json

Can be used to map the step ID to the step description.

{
    "step_idx": "step_description"
}

File: step_annotations.json

Contains metadata for each recording where the nature of recordings is just limited to the boolean. For information about the error category and the error description please see complete_step_annotations.json

{
    "1_7": {
        "recording_id": "1_7",
        "steps": [
            {
                "step_id": 3,
                "start_time": "start_time",
                "end_time": "end_time",
                "description": "description",
                "has_errors": "has_errors"
            }, 
            ....
        ]
    },
    ....
}

File: recording_id_step_idx.json

Contains information about the steps ids in each recording. Note: Step IDs of repetitive steps are repeated in the order in which they are performed in the recording.

{
    "1_7" : [3, 1, 4, 12 ...],
   "1_10" : [3, 1, 4, 11 ...],
   ...
}

File: error_annotations.json

This file contains the complete error annotations for each recording. We attach errors that occur during each step as part of the steps. Here, tag describes the error category and description presents the error description. Here we exclude information about the person and the environment in which they are recorded.

[
   {
        "recording_id": "1_10",
        "activity_id": 1,
        "is_error": true,
        "step_annotations": [
            {

            ...
        ]
    },
    ...
]

File: complete_step_annotations.json

This file contains the complete step annotations for each recording. It includes complete information about a recording namely (a) the person, (b) the environment, and (c) the errors that occur during each step of the recording
