ConfLab: A Data Collection Concept, Dataset, and Benchmark for Machine Analysis of Free-Standing Social Interactions in the Wild

ConfLab is a multimodal multisensor dataset of in-the-wild free-standing social conversations. It records a real-life professional networking event at the international conference ACM Multimedia 2019. Involving 48 conference attendees, the dataset captures a diverse mix of status, acquaintance, and networking motivations. Our capture setup improves upon the data fidelity of prior in-the-wild datasets while : 8 overhead-perspective videos (1920 x 1080, 60fps), and custom personal wearable sensors with onboard recording of body motion (full 9-axis IMU), privacy-preserving low-frequency audio (1250Hz), and Bluetooth-based proximity. Additionally, we developed custom solutions for distributed hardware synchronization at acquisition, and time-efficient continuous annotation of body keypoints and actions at high sampling rates.

General information: 

The dataset contains:

1. EULA: (DOI: 10.4121/20016194, required for access): End-User License Agreement needs to be filled out in order to request access because data contains pseudonymized data. Once completed, please return to SPCLabDatasets-insy@tudelft.nl. Private links to download the data will be sent to you when your credentials are reviewed and approved. Note for reviewers: please follow the same procedure described above. TUDelft Human Research Ethics Committee or a member of the Admin staff will handle your access requests for the review period to ensure single blind standard. 
2. Datasheet (DOI: 10.4121/20017559): data sheet summary of the ConfLab Data
3. Samples (DOI: 10.4121/20017682): sample data of the ConfLab dataset 
4. Raw-Data (DOI: 10.4121/20017748): raw video and wearable sensor data of the ConfLab dataset. 
5. Processed-Data (DOI: 10.4121/20017805): processed video and wearable sensor data of the ConfLab dataset. Used for annotations and processed for usability. 
6. Annotations (DOI: 10.4121/20017664): annotations of pose, speaking status, and F-formations.
