XR Motion Dataset Catalogue

Overview

The XR Motion Dataset Catalogue, accompanying our paper "Navigating the Kinematic Maze: A Comprehensive Guide to XR Motion Dataset Standards," standardizes and simplifies access to Extended Reality (XR) motion datasets. The catalogue represents our initiative to streamline the usage of kinematic data in XR research by aligning various datasets to a consistent format and structure.

Dataset Specifications

All datasets in this catalogue have been standardized with the following specifications:

• Coordinate System: X (Right), Y (Up), Z (Forward)
• Rotation Representation: Quaternions
• Units of Measurement: Centimeters for spatial data
• Time Encoding: Milliseconds for time-related data

These specifications ensure uniformity and comparability across all datasets in the catalogue.

Conversion Scripts Repository

The alignment of datasets was facilitated by a series of conversion scripts, which are available in our GitHub repository: XR Motion Dataset Conversion Scripts. These scripts detail the process of aligning attribute names, coordinate systems, rotation representations, units of measurement, and time encoding.

Included Datasets

The catalogue includes the following datasets:

1. LiebersBeatSaber23
2. Boxrr23 – edit 2024-05-04: we are still working on providing the aligned version – in the meantime you find the original version here
3. BOXRR24 – WIP: we are currently working on the next version of the BOXRR-23 dataset, which will include significantly more user – we do our best to make it available later this year
4. LiebersHand22
5. LiebersLabStudy21
6. MooreCrossDomain23
7. RMillerBall22 request for permissions pending
8. VrNet
9. WhoIsAlyx

Installation and Usage

Loading the Dataset with Hugging Face datasets Library

To load a dataset from the catalogue, use the datasets library in Python. For example, to load the WhoIsAlyx dataset:

from datasets import load_dataset

dataset = load_dataset("cschell/xr-motion-dataset-catalogue", "who_is_alyx", trust_remote_code=True)

Loading Individual Recordings with Pandas

To load individual recordings, you can use pandas. Here's an example:

import pandas as pd

file_url_path = "hf://datasets/cschell/xr-motion-dataset-catalogue/who_is_alyx/player_02/2022-01-07.parquet"
recording = pd.read_parquet(file_url_path)
