Is the emotional mapping of lines caused by the motion they imply?
Different patterns of lines can express different emotions, but the reason for the metaphor has not been fully revealed. Some studies speculate that this may be caused by the motion implied by lines. In order to verify this speculation, this paper conducts an experiment on the relationship between the emotional expression of lines and the motion of lines. We created 87 different patterns of lines and visualized the motion implied by the lines as dynamic effects. The subjects chose descriptors from a list of 29 emotion words for samples. The results show that the test samples can well cover the classical two-dimensional emotional space and the emotional expression of lines is obviously related to their implied motion. The implied motion, compared with the static version, tends to shift towards the positive and high arousal in the emotional space. In addition, the speed of the motion affects emotional arousal.
