Measuring the sub-group and movement alignment networks. a) Narrative chart represents proximity dynamics of a team. Each colored line represents a team member, close lines indicate moving sub-groups. Team members are either on ground level or above ground level. The sub-group network summarizes how long each team member was in a sub-group with which each other team member. Darker links indicate pairs that were together in a sub-group for more than 60% of the mission. b) Examples of high and low mutual information between two activity level signals. Activity level signals change more often simultaneously in the top graph as opposed to those shown in the bottom graph. Consequently, mutual information is higher for signals shown in the top graph. The movement alignment network summarizes how well team members aligned their activity levels in time. Darker links indicate pairs of team members that showed higher motion alignment than 60% of all other pairs in the data set.
