(A) Experimental setup for the tracking task: participants were separated by a curtain and tracked a visual target presented on the monitor using handles of the dual robotic interface Hi5. (B,C) Learning analysis using the tracking error (B) and the SPARC smoothness metric (C). The different connection conditions were: “solo” (no connection), “soft” 0.29 Nm/rad stiffness, “medium” 1.72 Nm/rad, “rigid” 17.02 Nm/rad. The dots represent the average of the corresponding metric for a trial and the area around it represents the ± 95% confidence interval estimated based on the least square fit of a second order polynomial. The horizontal yellow bars correspond to the metric’s value in the initial trial. Figures 2(B,C), 3, 4, 5 were created using RStudio (Version: 1.2.1335; https://www.rstudio.com/).
