In Wizard-of-oz Mockup, sounds are created live using a microphone, or with the help of electro-acoustic sound generators, using objects, your voice and body sounds, and rendered "acousmatically" (without a visible source). This happens synchronously to the interaction, just as Foley is synced to film. This creates a near-perfect illusion of interactive sound design without it having to be functionally implemented.
Especially in the early stages of the project, this allows maximum flexibility and open-mindedness. Thus, the first sound design ideas can be tested and adapted live, from a "sonic concept sketch" to a full-blown function demonstration.
Specifically, you will be using MuLab as a host for multisampler arrangements in real-time to interact with your application. Midi keyboards are used as real-time controllers. "Wizards" create and control sounds hidden behind a curtain or similar and one or more people perform the interaction. It should also be possible for someone in the audience to try out the artifact / interaction.
Process of a Mockup Demonstration
Brief explanation of the setting and function of the prototype
Interactive demo with audience tryout: People from the audience can try out the interaction themselves
If necessary, further explanation of the concept and the implementation
Presentation of the results of the field trial
Discussion in the audience: What worked, what did not work?
