Traditional lab-based play sessions do not capture naturalistic social behavior, and wearable video creates large volumes that strain manual coding. A machine-learning pipeline is introduced to analyze everyday interactions from 224 hours of camera-wear data collected from 64 children aged 3–5 in Leipzig since 03/2020, focusing on presence, face, gaze, and voice cues. Results use YOLO to reach 80% person detection accuracy and 0.9 F1 for face detection.","UC Merced  \nProceedings of the Annual Meeting of the Cognitive Science Society  \nTitle  \nLeveraging Machine Learning and Wearable Cameras to Analyze Children's Social Interactions  \nPermalink  \n[https://escholarship.org/uc/item/4r5284w3](https://escholarship.org/uc/item/4r5284w3)  \nJournal  \nProceedings of the Annual Meeting of the Cognitive Science Society, 47(0)  \nAuthors  \nSuffo, Nele-Pauline  \nMartin, Pierre-Etienne Zahra, Anam  \net al.  \nPublication Date  \n2025  \nCopyright Information  \nThis work is made available under the terms of a Creative Commons Attribution License, available at [https://creativecommons.org/licenses/by/4.0/](https://creativecommons.org/licenses/by/4.0/)  \nPeer reviewed  \n[eScholarship.org](eScholarship.org) Powered by the California Digital Library  \nUniversity of California  \nLeveraging Machine Learning and Wearable Cameras to Analyze Children’s Social  \nInteractions  \nNele-Pauline Suffo  \nLeuphana University, Lüneburg, Germany  \nPierre-Etienne Martin  \nMax Planck Institute for Evolutionary Anthropology, Leipzig, Germany  \nAnam Zahra  \nMax Planck Institute for Evolutionary Anthropology, Leipzig, Germany  \nDaniel Haun  \nMax Planck Institute for Evolutionary Anthropology, Leipzig, Saxony, Germany  \nManuel Bohn  \nMax Planck Institute for Evolutionary Anthropology, Leipzig, Germany  \nAbstract  \nDirect insights into children’s daily experiences are limited despite their importance for development (Rogoffet al., 2018) . Traditional methods, like laboratory play sessions, fail to capture naturalistic interactions. Wearable recording devices provide richer data, but their sheer volume challenges traditional coding. We introduce a machine-learning approach to analyze children’s everyday interactions. Sixty-four children (ages 3–5) in Leipzig, Germany, wore vests with small cameras, recording 224 hours of video since 03/2020 . Our analysis focuses on social interaction cues: person presence, face, gaze, and voice. Using YOLO11, we achieved 80% accuracy in person detection and a 0.9 F1 score for face detection. Preliminary results indicate children often spend time alone or with one person, with face presence in only 17.75% of frames. We will next integrate gaze and voice detection to assess child-directed speech. Our machine-learning approach provides novel insights into children’s natural social environments, advancing research on early development.  \n6423  \nIn D. Barner, N.R. Bramley, A. Ruggeri and C.M.
