文件，介绍了一个正在进行的研究项目的第二阶段处理的互动界面的实现。它是一种“免提”仪器，利用基于机载超声波的非接触式触觉反馈方法。本文将讨论的接口的三个主要元素/组件是：1。在超声波信号通过空气传播期间通过超声波信号的自解调产生可听声音; 2.超声能量在一个空间点中的凝聚，产生可听声音的精确触觉再现;以及3.前馈方法通过直接用手塑造触觉（超）声音，实现音乐家的实时干预。
paper, describes the second phase of an ongoing research project dealing with the implementation of an interactive interface. It is a "hands free" instrument, utilizing a non-contact tactile feedback method based on airborne ultrasound. The three main elements/components of the interface that will be discussed in this paper are: 1. Generation of audible sound by self-demodulation of an ultrasound signal during its propagation through air; 2. The condensation of the ultrasound energy in one spatial point generating a precise tactile reproduction of the audible sound; and 3. The feed-forward method enabling a real-time intervention of the musician, by shaping the tactile (ultra)sound directly with his hands.
