interaction-design

Designing user flows and state machines involves mapping user tasks, defining screen states, and annotating transitions to ensure coherent experiences. This approach reduces cognitive load by clarifying controls, feedback, and information flows across traditional and spatial interfaces.

Interaction design is the process of defining how users interact with digital products through controls, feedback, and information flows. You need it when bridging user needs and system capabilities to reduce friction, ensuring intuitive micro-interactions and clear state transitions in prototypes.

Applying usability heuristics to validate interfaces extends beyond traditional screens to emerging paradigms like spatial, conversational, and gesture-based interfaces. It involves performing heuristic reviews and accessibility considerations to document deliverables such as user flows and prototype specifications.

The best way to document micro-interactions for handoff is creating wireframes and prototypes with clear annotations for developers. This includes specifying component states, state diagrams, and design-system-aligned deliverables to streamline collaboration.

Mapping state transitions for a login signup flow requires defining clear state requirements, feedback mechanisms, and error handling. You sketch key screens, annotate component states, and document user flows to ensure a coherent, low-friction authentication experience.
