In order to determine a way to make people in close proximity more intimate, I imagined a social situation in which nonverbal communication would be of great importance: a party, crowded with people who you both like and dislike. I also used The Nonverbal Dictionary to refresh my familiarity with the nonverbal methods I learned in Speech and Debate class in high school.
The arm-cross is a classic nonverbal cue that is "unconsciously used to alleviate anxiety and social stress." A study on college students even found that "women use open arm positions with men they like, but cross-arms with men they dislike." The study concluded that men show no difference in this regard, but I beg to differ, as I know I cross my arms when I'm talking to people I dislike.
Since the goal of this week's project was to increase intimacy, it would make sense that a reduction in arm crossing could facilitate more intimacy. My design prototype is a shirt with a pressure sensor band underneath the fabric across the chest, which would detect the presence of the wearer's arms in a crossed position.
When pressure is detected, a light shock is applied to the wearer's arms, causing them to immediately release their standoffish posture. A few times of this shock therapy is all that's required for a more intimate social experience. The results can be seen below:
