Vibration has the potential to convey expressive and affective qualities, similar to how color communicates emotion in visual interfaces. However, systematic evidence for such correspondences remains limited. This paper presents a controlled perceptual study examining whether vibration amplitude and frequency elicit consistent associations with both emotion and color. Participants completed amplitude-only, frequency-only, and combined conditions while providing affective ratings (valence, arousal, and emotion labels) and selecting corresponding color attributes (hue, brightness, and saturation). Results showed that increasing amplitude led to higher arousal ratings and color selections with greater saturation but lower brightness, while increasing frequency modestly elevated arousal and biased hue toward warmer tones and higher saturation. Combined conditions produced the strongest arousal responses, with a significant amplitude–frequency interaction. Color associations showed parallel but nonsignificant shifts toward warmer and more saturated hues, suggesting partial convergence among vibrotactile intensity, emotional activation, and perceptual color warmth. These findings demonstrate that vibrotactile parameters can systematically shape perceptual and affective responses, offering a foundation for expressive haptic design.
