This paper reports on a Short-Term Scientific Mission (STSM)sponsored by the Sonic Interaction Design (SID) EuropeanCOST Action IC601.Prototypes of objects for the novel instrument Reactablewere developed, with the goal of studying sonification ofmovements on this platform using physical models. A physical model of frictional interactions between rubbed dry surfaces was used as an audio generation engine, which alloweddevelopment in two directions — a set of objects that affordsmotions similar to sliding, and a single object aiming tosonify contact friction sound. Informal evaluation was obtained from a Reactable expert user, regarding these sets ofobjects. Experiments with the objects were also performed- related to both audio filtering, and interfacing with otherobjects for the Reactable.
