Intuitive Control of Scraping and Rubbing Through Audio-tactile Synthesis (2401.05757v1)

Abstract: Intuitive control of synthesis processes is an ongoing challenge within the domain of auditory perception and cognition. Previous works on sound modelling combined with psychophysical tests have enabled our team to develop a synthesizer that provides intuitive control of actions and objects based on semantic descriptions for sound sources. In this demo we present an augmented version of the synthesizer in which we added tactile stimulations to increase the sensation of true continuous friction interactions (rubbing and scratching) with the simulated objects. This is of interest for several reasons. Firstly, it enables to evaluate the realism of our sound model in presence of stimulations from other modalities. Secondly it enables to compare tactile and auditory signal structures linked to the same evocation, and thirdly it provides a tool to investigate multimodal perception and how stimulations from different modalities should be combined to provide realistic user interfaces.
