VisualTouch device. (A) Shows the interface presented on the smartphone through which the participants can create/send visual-touch stimuli. (B) Shows an excerpt of the interaction of a couple. On the left, the visual effect on the forearm of the interactant is produced by the use of the smartphone of the interactant on the right (due to a decay effect on the visual and short transmission delay, three red dots can be seen on the screen while there is only one on the smartphone). For a better understanding, short video excerpts are available online in Supplementary Videos 1, 2.
