Metacommunication

In semiotic engineering, metacommunication refers to the overarching communication that takes place between a software designer and a user through the medium of the computer interface. The interface acts as the designer's deputy, conveying messages about what the system does, why it was designed that way, how it should be used, and what the designer believes about the user's needs and preferences. Metacommunication is distinct from direct communication because it is one-way (designer to user, mediated by the interface) and is necessarily incomplete — the computer cannot reproduce the full complexity of human language. Breakdowns in metacommunication occur when the interface's signs fail to convey the designer's intent, leading to user confusion, errors, or technology abandonment. In assistive technology design, effective metacommunication is critical because users may have diverse and complex needs that require clear guidance through configuration and customisation options.
