CHI '16


Summary

  • Shape and movement involve emotions
  • Experiment 1
    • asked 20 participants to make shape for the list of emotions
    • asked them to rate the emotions regarding Valence and Arousal to calculate Euclidian distance between emotions
  • Experiment 2
    • made videos of the shape-change
    • showed the videos to different 20 participants. They needed to choose one of the list of emotions or no emotion.


What I learned

  • Unique structure
    • Explicit Contribution section in Introduction
    • Instead of related work, used Background to give background knowledge such as Russell's Circumplex Model, to persuade that shape is related to emotion or nonverbal communication
    • Used dedicated sections for results. The result section has several subsections to interpret the result
  • Fleiss kappa
  • Referred Morphees paper to identify terms for shapes


How to improve

  • It might be different when the users could touch the movement -> described in Limitations.
  • As experiments 1 showed higher coherence, touching the interface may induce more accurate emotional interpretation.
  • If the participants were given less number of emotions, it would result higher accuracy. The high agreement of the axis (positive vs. negative Valence and high vs. low Arousal) shows the feasibility. In a future work, it may show feasibility of reduced number of emotions to convey shape-change to emotions.
