Understanding and Measuring User Emotions: The Missing Puzzle Piece
summary
Emotion measurement uses concrete signals and tools: skin conductance = arousal (millisecond resolution, Biopac or Empatica/Shimmer wearables), heart rate deceleration flags aversive responses, pupil size and Tobii eye tracking index attention and arousal, and corrugator and zygomaticus EMG map unpleasant vs pleasant valence (or use Affectiva/iMotions for micro‑expressions). LIWC or human coding handles sentiment from text. Best practice pairs at least two methods, collects baselines, accounts for activity and light, and controls for cultural/contextual differences to avoid misinterpretation.
