We report in this paper on work in progress to develop gestural interfaces that allow for simultaneous multidimensional control. An example of simultaneous multidimensional control can be found in music composition and sound design, in which task the control of timbre involves many inter-dependent parameters simultaneously. For any sound designer or sound composer the control of these parameters involves a significant amount of cognitive processing to coordinate his or her motor system when mouse-and-keyboard interfaces are used. Thus, to reduce the cognitive load for the sound designer, it is necessary to design a human computer interface that implements data reduction and/or an interface that exploits the capability of human gestures to effortlessly vary many degrees of freedom simultaneously. In terms of data reduction, sound synthesis models that parametrize timbre independently at a perceptual level only generate a limited number of timbres. While the human hand is well-suited for multidimensional control due to its detailed articulation, most gestural interfaces do not exploit this capability due to a lack of understanding of the way humans produce their gestures and what meaning can be inferred from these gestures. In order to facilitate quick prototyping and experimentation with a multitude of gestural analysis methods, we are approaching the design problem by creating a set of tools that facilitate the computation of various gesture features and parameters.
