300 Vibrotactile Stimuli in Mobile Devices: Exploring and Estimating the Effect of 5 Vibrotactile Parameters on Emotional Responses

This paper explores the emotional responses of vibrotactile stimuli in mobile devices. Previous studies have limitations in parameter setting, experimental equipment, and emotion estimation. To address these, we constructed a parameter system and conducted an experiment with 25 participants to explore emotional responses to 300 vibrotactile stimuli. Quantitative results revealed that all 5 parameters significantly influenced emotional responses. Qualitative results indicated that participants’ perceptions of vibrotactile stimuli influenced by various factors, including physical perception differences, personal cognition and experiences, emotional resonance, and crossmodal perception. In addition, an artificial neural network model was developed to estimate vibrotactile emotional responses, demonstrating sufficient accuracy. This study provides guidelines for the emotional design of vibrotactile feedback in mobile devices.

本文探讨了移动设备中振动触觉刺激（vibrotactile stimuli）引发的情绪反应。以往研究在参数设置、实验设备及情绪评估方面存在局限。为解决这些问题，我们构建了一套参数体系，并招募25名参与者开展实验，探究其对300种振动触觉刺激的情绪反应。定量结果表明，所有5个参数均对情绪反应产生显著影响。定性结果显示，参与者对振动触觉刺激的感知受多种因素影响，包括物理感知差异、个人认知与经验、情绪共鸣及跨模态感知（crossmodal perception）。此外，我们开发了人工神经网络（artificial neural network）模型用于评估振动触觉情绪反应，其准确性达到了足够水平。本研究为移动设备中振动触觉反馈的情绪设计提供了指导依据。
