Based on the type of projects I see currently happening I see three main responsibilities for an Interaction Designer. As a designer of Human-Computer interaction, one must represent
- How does it work?
- How does the process, the flow, the various states of the interface, the scenarios and exceptions work for user and the system in various contexts. A true understanding of everything related to how the system functions.
- How does it feel?
- In what way does the system interact with the user.
- What problem does this solve
- Stakeholder management; Provide insights in what has the most user or business value and what feature should be considered in scop of the minumum viable product.
