A. Filtering procedure: only contacts of duration at least T	Average daily number of distinct other children in contact	Average daily cumulated duration of contacts with other children, in minutes
T = 0	47.4	176
T = 40 s	20.8	100
T = 1 mn	11.8	65
T = 2 mn	4..1	28
T = 3 mn	2.2	19

A. Average number of children with whom a child was in contact, computed over one day, and average total time spent daily in contact with other children. In both cases, a filtering that retains only the contacts with duration at least equal to T is applied (T = 0 or 20 s corresponds to taking all contacts into account, given the available 20 s time resolution). B. Average number of children with whom a child was in contact, computed over one day, and average total time spent daily in contact with other children. For both quantities, a filtering procedure is applied that retains only the links between children who have spent an amount of time at least equal to W in face-to-face proximity (W = 0 or 20 s corresponds to taking all links into account).
