Typical example of the force as a function of time for Pair 12 in the one-coin condition. The blue trace represents the force recorded from participant A and the red trace represents the forces recorded from participant B. Both forces are in the horizontal direction. Condition 1 is the simplest environment for paired participants given that only one target was presented at a time. The force time series also shows an overlap of forces during the experiment, which again suggests that participants shared control of the device. If participants had distributed control over the device it would be visible in the time series as alternating peaks.
