“…Recent advances in wearable devices-lightweight "headcams" that record infant-perspective visual experiences and audio recorders that can capture daylong recordings of infant and adult speech-provide researchers with new ways to capture home experiences at scale [36][37][38]. Headcam recordings over the first two years of life show that the frequency of faces in infants' views decreases with age while that the presence of hands increases in frequency [37].…”

“…These full-day recordings di↵ered from brief laboratory observations: 12-month-olds were upright 50-70% of the time in laboratory play [19,23] compared with 30% of the time in the home. A future alternative may be to use lightweight inertial sensors [38]: Posture has been accurately classified in small samples of infants in controlled tasks [43], but soon these methods may be suitable for home recordings.…”

The first goal of this article is to review recent advances in understanding how new motor skills facilitate infants' exploration-the active acquisition of information about their environments. New postural abilities, such as sitting and walking, qualitatively change how infants can learn about objects, places, and people with with potential downstream e↵ects on infants' later cognitive and linguistic development. What's missing, however, is a characterization of how new exploratory abilities change infants' everyday experiences. Presumably, changes in opportunities for learning mediate the downstream e↵ects of posture on other developmental achievements. Accordingly, the second goal of this article is to discuss the importance of measuring the ecology of infants' everyday experiences and how they vary.

“…Herein, we introduce the TotTag -a novel tool for measuring natural patterns of physical proximity between children and caregivers. We propose that observing patterns of caregiver-child proximity as they unfold in real time and in a family's natural contexts (e.g., outside of the laboratory setting) provides a novel perspective on the early caregiving environment and fills an important gap by addressing the need for more ecologically-valid approaches to our understanding of children's early experiences (de Barbaro, 2019;Rogoff, Dahl, & Callanan, 2018).…”

The types of interactions that we believe to be most supportive of positive child development (e.g., joint attention, physical touch) take place in moments of close contact with others, and in the earliest years of life a child’s caregivers are the primary partners in these important interactions. However, we know little about the patterns of real-life interactions between children and their caregivers. To address this gap, we have developed a wearable, infrastructure-free device (TotTag) used to dynamically and unobtrusively measure real-time physical proximity between children and caregivers throughout the day. The present study examines the TotTag validity and reliability with data collected over two days from a family of four (30-month-old son, 61-month-old daughter, 37-year-old father, 37-year-old mother), including information about their patterns of interaction as well as how the children’s experiences might differ depending on proximity to their caregivers. We explored patterns of proximity across the day within each parent–child dyad and whether measurements corresponding to close proximity between child and caregiver would indicate periods in which increased opportunity for developmentally critical interactions occur. Each child also wore a widely-used wearable audio recording device (LENA) to collect time-synced linguistic input. Descriptive analysis of the TotTag data reveal wide variability in caregiver–child proximity over the course of the recordings. Further, results suggest that the amount of time spent in close proximity with a caregiver is associated with the quantity of a child’s exposure to adult language, suggesting that variations in proximity are linked to, though not synonymous with, the experience of adult speech. Potential implications for deepening understanding of early caregiver–child interactions are discussed.

“…It can therefore become a powerful tool for the management of chronic disease [24] and mental health problems [25][26][27], for example in monitoring and supporting behavioral change for adolescent mothers receiving psychological interventions. Given the great complexity and volume of digital data that can be collected through this technique, digital phenotyping has the potential to elucidate the complex interactions that in uence development [28] , psychology [29,30], and stress [31] in new ways. For example, features of movement extracted from passive sensing data have been associated with loneliness [30], worsening of depressive mood [32], and changes in state of patients with bipolar disorder [26].…”

“…Bluetooth beacons have been used to measure proximity to other individuals to study social contact [44], and they are acceptable and feasible among women in rural South Africa [46]. Social environment has been examined as an important factor in overall well-being [47] 28 , and opportunities exist to examine what measures of social interactions can tell us about the experiences of perinatal women.…”

Adolescent motherhood in rural Nepal: passive sensing data illuminates daily experiences in maternal lives

Background: Adolescent pregnancy, particularly in low-income settings, is associated with adverse health and social outcomes for both mother and child. Nepal has the second highest rate of adolescent pregnancy in South Asia alongside high rates of maternal depression and suicide. While the maternal morbidity risks of adolescent pregnancy are well researched, impacts on everyday lives, including behaviors and predictable patterns are less well-known. Passive sensing (geographic movement, physical activity, and proximity to infants using Bluetooth technology) is an emerging technology that can enhance the detection of behavior patterns. Given the risk of the postpartum period in LMIC settings, we sought to characterize normal behavioral patterns via passive sensing technology. Methods: We collected passive data over a two-week period with 22 mothers using phone-based GPS, accelerometry, and Bluetooth technologies. Passive data was aggregated for each mother, collapsed into hourly readings, and descriptively summarized. We triangulated this information in a constant comparative approach with a range of qualitative data including multiple in-depth interviews, a daily diary, and systematic fieldnotes. Results: Passive data illuminated a range of behaviors that varied across our participants. Women, during the average time window of 4am and 8pm, spent more than 80% of the day with their infants, were detected as ‘active’ 10-20% of the time in any given hour with peaks in the morning and mid-afternoon, and traveled fewer than 1675 meters from their homes. Household work, instrumental childcare, and household support, paired with the infant’s age, appeared to drive activity patterns. Women with higher amounts of activity and GPS movement had more household support for chores and childcare. Women with young infants had smaller amounts of activity and GPS movement. Women that had nearly no time away from their infant expressed overwhelming responsibilities and increased stress, but also role fulfillment in that time with their infant was an indicator of good mothering. Conclusion: We reveal typical behavioral patterns of rural adolescent mothers and highlight opportunities for integrating this information to improve health and well-being.
