There have been sustained efforts toward using naturalistic methods in developmental science to measure infant behaviors the real world from an egocentric perspective because statistical regularities environment can shape and be shaped by developing infant. However, there is no user-friendly unobtrusive technology densely reliably sample life wild. To address this gap, we present design, implementation validation of EgoActive platform, which addresses limitations existing wearable technologies for research. records active infants’ via a miniature wireless head-mounted camera concurrently with their physiological responses input lightweight, ECG/acceleration sensor. We also provide software tools facilitate data analyses. Our studies showed that cameras body sensors performed well. Families reported platform was comfortable, easy use operate, did not interfere daily activities. The synchronized multimodal help tease apart complex processes are important child development further our understanding areas ranging executive function emotion processing social learning.
