Abstract : The presented study is part of a general framework consisting in designing an intuitive control strategy of a generic synthesis model simulating continuous interaction sounds such as scraping, sliding, rolling or rubbing. For that purpose, we need to identify perceptually relevant signal properties mediating the recognition of such sound categories. Some studies tend to suggest the existence of acoustic features related to velocity or periodic modulations but, to our knowledge, the auditory distinction between these interactions is still not well-known and no formal investigations have been conducted so far. This study aimed at presenting a perceptual evaluation method, with brings to the light the differences between these interaction sounds. Such sounds were synthesized based on existing models and a morphing procedure between these sound categories was used to create intermediate sounds. Then, sounds were evaluated by subjects in a categorization task. Analyses of data revealed characteristic signal morphologies associated to each interaction sound category, thereby useful for the design of intuitive control of the generic synthesis model.
