提出了一种实时合成不同材料上的脚步声的系统。该系统基于麦克风，允许用户与自己的鞋子进行交互。该解决方案将我们的系统与之前需要使用传感器增强的特定鞋子的系统区分开来。麦克风检测用户的真实脚步声，并据此估算地面反作用力 (GRF)。这种GRF用于控制基于物理模型的声音合成引擎。描述了系统在交互的有效性和保真度方面的评估。
A system to synthesize in real-time the sound of footsteps on different materials is presented. The system is based on microphones which allow the user to interact with his own footwear. This solution distinguishes our system from previous efforts that require specific shoes enhanced with sensors. The microphones detect real footsteps sounds from users, from which the ground reaction force (GRF) is estimated. Such GRF is used to control a sound synthesis engine based on physical models. Evaluations of the system in terms of sound validity and fidelity of interaction are described.
