Visual Associations in Augmented Keyboard Performance

What is the function of visuals in the design of an augmented keyboardperformance device with projection? We address this question by thinkingthrough the impact of choices made in three examples on notions of locus ofattention, visual anticipation and causal gestalt to articulate a space ofdesign choices. Visuals can emphasize and deemphasize aspects of performanceand help clarify the role input has to the performance. We suggest that thisprocess might help thinking through visual feedback design in NIMEs withrespect to the performer or the audience.
