However, there is no user-friendly and unobtrusive technology to densely and reliably sample life in the wild. To address this gap, we present the design, implementation and validation of the EgoActive platform, which addresses limitations of existing wearable technologies for developmental research. EgoActive records the active infants\u2019 egocentric perspective of the world via a miniature wireless head-mounted camera concurrently with their physiological responses to this input via a lightweight, wireless ECG\/acceleration sensor. We also provide software tools to facilitate data analyses. Our validation studies showed that the cameras and body sensors performed well. Families also reported that the platform was comfortable, easy to use and operate, and did not interfere with daily activities. The synchronized multimodal data from the EgoActive platform can help tease apart complex processes that are important for child development to further our understanding of areas ranging from executive function to emotion processing and social learning.<\/jats:p>","DOI":"10.3390\/s23187930","type":"journal-article","created":{"date-parts":[[2023,9,17]],"date-time":"2023-09-17T23:57:46Z","timestamp":1694995066000},"page":"7930","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["EgoActive: Integrated Wireless Wearable Sensors for Capturing Infant Egocentric Auditory\u2013Visual Statistics and Autonomic Nervous System Function \u2018in the Wild\u2019"],"prefix":"10.3390","volume":"23","author":[{"given":"Elena","family":"Geangu","sequence":"first","affiliation":[{"name":"Psychology Department, University of York, York YO10 5DD, UK"}]},{"given":"William A.
