“…Indeed, these more traditional approaches fall short in providing highly accurate kinematic information because they are (i) prone to human error, (ii) rater dependent, (iii) generally very time-consuming, and (iv) rarely comprehensive in characterizing full-body kinematics. Furthermore, even though kinematic estimates based on video cameras are not as precise as those yielded by infrared cameras [(e.g., systems such as Vicon, Optitrack, and Qualisys, see 9 , 42 , 45 , 46 , 47 , 48 , the former are less expensive, less cumbersome, and they do not involve wearing specialized markers, making this method very accessible and suited for ecological and field studies. 49 , 50 …”

“…A more recent study showed that two participants engaged in a classical movement coordination task (i.e. rhythmic synchronization of finger flexion/extension as in [18] but performed at a slower pace), generate submovements with a systematic temporal relationship to each other [19]. This finding suggests that when participants need to incorporate visual information provided by their partner to organize their motor output, this is reflected in nontrivial reciprocal coupling at the level of submovements.…”

Movements are naturally composed of submovements, i.e. recurrent speed pulses (2–3 Hz), possibly reflecting intermittent feedback-based motor adjustments. In visuomotor (unimanual) synchronization tasks, partners alternate submovements over time, indicating mutual coregulation. However, it is unclear whether submovement coordination is organized differently between and within individuals. Indeed, different types of information may be variably exploited for intrapersonal and interpersonal coordination. Participants performed a series of bimanual tasks alone or in pairs, with or without visual feedback (solo task only). We analysed the relative timing of submovements between their own hands or between their own hands and those of their partner. Distinct coordinative structures emerged at the submovement level depending on the relevance of visual feedback. Specifically, the relative timing of submovements (between partners/effectors) shifts from alternation to simultaneity and a mixture of both when coordination is achieved using vision (interpersonal), proprioception/efference-copy only (intrapersonal, without vision) or all information sources (intrapersonal, with vision), respectively. These results suggest that submovement coordination represents a behavioural proxy for the adaptive weighting of different sources of information within action-perception loops. In sum, the microstructure of movement reveals common principles governing the dynamics of sensorimotor control to achieve both intra- and interpersonal coordination.

“…In their study, the direction of exchanges was exclusively from the leader to the follower, the former had no way to perceive the movements of the follower. Recently such oscillatory submovements at 2–3 Hz were also found in birectional interaction between two individuals, using a visual synchronization task 33 . It is also noteworthy that studies have found neural correlates of submovements frequencies lying between 2 and 5 Hz in primary motor and sensory areas, which were phase-locked to movement speed fluctuating at those frequencies 27 .…”

“…Of particular interest could be the submovements that lie in the range 2-3 Hz, which are often attributed to time-delays in visuo-motor control loops (33). In the case of interaction between individuals, Noy et al (2011) (30), using a mirror-game in which a follower visually reproduced the leader's movement, found a 2-3 Hz jitter super-imposed to the slower main movement which itself had in average a frequency of 1.5 Hz.…”

Object-mediated joint action is believed to be enabled by implicit information exchange between interacting individuals using subtle haptic signals within their interaction forces. The characteristics of these haptic signals have, however, remained unclear. Here we analyzed the interaction forces during an empirical dyadic interaction task using Granger–Geweke causality analysis, which allowed us to quantify the causal influence of each individual’s forces on their partner’s. We observed that the inter-partner influence was not the same at every frequency. Specifically, in the frequency band of [2.15–7] Hz, we observed inter-partner differences of causal influence that were invariant of the movement frequencies in the task and present only when information exchange was indispensable for task performance. Moreover, the inter-partner difference in this frequency band was observed to be correlated with the task performance by the dyad. Our results suggest that forces in the [2.15–7] Hz band constitute task related information exchange between individuals during physical interactions.
