N2 - This study investigates whether emotions can be recognized through LED-only visual cues using color and animation patterns. 31 participants viewed six short videos representing basic emotions(Happiness, Sadness, Anger, Fear, Disgust and Surprise) and identified the emotion conveyed. Anger and Sadness were most accurately recognized, while Disgust and Fear were frequently misinterpreted. Participants cited color, blinking speed, and pattern rhythm as key influences. These findings highlight the potential of minimalist LED displays as lightweight, non-verbal communication tools in human-robot interaction, particularly for expressing high-arousal emotions.
