手机上的对话伙伴可以在没有身体接近或视觉反馈的情况下调整他们的走路姿势。当用户通过手机交谈时,我们通过加速计测量步态同步。利用希尔伯特变换来推断步态相位角,利用同步理论中的技术来推断对齐水平。实验条件包括使用振动触觉反馈,使对话中的一方意识到另一方的脚步。测试了三种互动模式:阅读剧本、讨论共享的图像和自发的对话。振动触觉反馈回路本身就足以产生同步,但当用户自发交谈时,会产生复杂的干扰效应。即使没有振动串扰,在自发说话的情况下,同步现象也会持续很长一段时间,这表明用户仅仅根据声音提示来调整他们的行走行为。
Conversation partners on mobile phones can align their walking gait without physical proximity or visual feedback. We investigate gait synchronization, measured by accelerometers while users converse via mobile phones. Hilbert transforms are used to infer gait phase angle, and techniques from synchronization theory are used to infer level of alignment. Experimental conditions include the use of vibrotactile feedback to make one conversation partner aware of the other's footsteps. Three modes of interaction are tested: reading a script, discussing a shared image and spontaneous conversation. The vibrotactile feedback loop on its own is sufficient to create synchronization, but there are complex interference effects when users converse spontaneously. Even without vibration crosstalk, synchronisation appeared for long periods in the spontaneous speech condition, indicating that users were aligning their walking behaviour from audible cues alone.
