The actor’s lips move at the centre of the screen. Their voice leaves a loudspeaker several metres away. Nobody points towards the wall.
The picture supplies location. Sound accepts it.
A dubbed line arrives late. The mouth closes before the final word. Several people shift in their seats. The same voice that felt attached to a face now seems to hover in the auditorium.
Prototype one.
A payment tone sounds. The screen remains unchanged for half a second. The tester presses twice.
Prototype two.
The visual state changes first. The tone follows late. The tester waits, then asks whether payment completed.
Prototype three.
Colour, movement and tone change together. The tester continues.
The tone is identical across all three versions.
Prototype four removes colour. One tester misses the change.
Prototype five removes tone. Another tester looks away during the visual transition and asks what happened.
Prototype six adds a short vibration at the same instant. The state remains legible through more than one sense.
Prototype seven delays only the vibration. Two testers look back at their hands.
Prototype eight moves the confirmation to the corner of the display. Eyes follow the movement and the central message is missed.
Prototype nine keeps every signal together and shortens the transition. One tester describes it as faster although processing time is unchanged.
The session notes contain no theory of ventriloquism. They contain presses, pauses, questions and the moment each signal arrived.
At 16.42 the laptop speakers are accidentally muted. The final tester sees the state change and continues. The vibration motor remains disconnected.
