Interaktionslogik

Interaktionslogik is a concept used in German-language discussions of interaction design and human-computer interaction to describe the logical structure that governs how users interact with a system. It encompasses the sequences of user actions, the system responses, state transitions, and the rules that link input to feedback. The term is frequently used to analyze how an interface guides behavior, maintains consistency, and supports task completion across different contexts and modalities.

Its core components include input modalities (touch, voice, keyboard, gesture), system states (idle, processing, error), rules of interaction (what commands are valid, what feedback is provided), and feedback mechanisms (visual, auditory, haptic). Design goals emphasize clarity, predictability, efficiency, and error resilience. Modeling approaches often draw on state machines, task analysis, and cognitive walkthroughs to capture how users move through tasks and how the system should respond at each step.

Applications appear in consumer software, mobile devices, voice assistants, interactive kiosks, automotive user interfaces, and industrial control environments. Challenges include latency, ambiguity in user intent, accessibility across abilities, and consistency across platforms. Ongoing work explores adaptive interfaces that adjust logic to user goals while maintaining safety and explainability, as well as cross-disciplinary methods integrating psychology, linguistics, and design practice.
