From action to sound: a challenging perspective for haptics

The link from action to sound is under-explored in virtual realities. The article categorizes the action-sound relations, proposing the term "ergotic" to refer to the case when there is a mechanical interaction between the subject and the sound source. Force-feedback devices and physically based models are indeed required for implementing virtual ergotic action-sound systems, able to engrave the energetic consistency of the physical action in the sound.
