Abstract:

A key challenge in the design of Virtual Musical instruments (VMIs) is finding expressive, playable, learnable mappings from gesture to sound that progressively re-ward practice by performers. Designing such mappings can be particularly demanding in the case of non-contact musical instruments, where physical cues can be scarce. Unaided intuition works well for many instrument de-signers, but others may find design and evaluation heuristics useful when creating new VMIs. In this paper we gather existing criteria from the literature to assemble a simple set of design and evaluation heuristics that we dub articulacy. This paper presents a design case study in which an expressive non-contact finger-tracking VMI, Sound Spheres, is designed and evaluated with the sup-port of the articulacy heuristics. The case study explores the extent to which articulacy usefully informs the design of a non-contact VMI, and we reflect on the usefulness or otherwise of heuristic approaches in this context.
