The laptop performer's hidden physical actions create an audience perception problem: is this live or playback?

In a laptop performance (audio or visual), the audience sees a person looking at a screen and occasionally moving a mouse or pressing keys. There is no physical gesture that unambiguously signals live creation. Unlike a guitarist (whose hand movements directly produce sound) or a dancer (whose body is the work), the laptop performer’s effort is invisible. This creates a credibility gap: the audience cannot verify liveness. This is not merely a perception problem — it shapes the emotional engagement. Strategies to address it: show the screen (code, interface), use live cameras with visible physical setups, add bodily gesture via controllers or gestural interfaces, or reframe the performance to make process visible.

Examples

Slub (live coding duo) projects their code terminal so audiences watch code being written as it generates sound. AVCENTRALEN built a visible physical ‘laboratory’ of miniature setups filmed live.

Assessment

Identify the specific problem the laptop performer has that a pianist does not, and propose two solutions with different trade-offs.
