Query: Subtle Contact Nuances in the Delivery of Human-to-Human Touch
  Distinguish Emotional Sentiment   We routinely communicate distinct social and emotional sentiments through
nuanced touch. For example, we might gently hold another's arm to offer a sense
of calm, yet intensively hold another's arm to express excitement or anxiety.
As this example indicates, distinct sentiments may be shaped by the subtlety in
one's touch delivery. This work investigates how slight distinctions in
skin-to-skin contact influence both the recognition of cued emotional messages
(e.g., anger, sympathy) and the rating of emotional content (i.e., arousal,
valence). By self-selecting preferred gestures (e.g., holding, stroking),
touchers convey distinct messages by touching the receiver's forearm.
Skin-to-skin contact attributes (e.g., velocity, depth, area) are optically
tracked in high resolution. Contact is then examined within gesture, between
messages. The results indicate touchers subtly, but significantly, vary contact
attributes of a gesture to communicate distinct messages, which are
recognizable by receivers. This tuning also correlates with receivers' arousal
and valence. For instance, arousal increases with velocity for stroking, and
depth for holding. Moreover, as shown here with human-to-human touch, valence
is tied with velocity, which is the same trend as reported with brushes. The
findings indicate that subtle nuance in skin-to-skin contact is important in
conveying social messages and inducing emotions.
