Important questions to consider when designing for interaction include the following:

- Defining how the user interacts with the interface: What does the user do with their finger, stylus, keyboard, or mouse to interact with the interface?

- Giving users clues about behaviors before actions are taken: What does the appearance (color, shape, size, animation, etc) of an element or system tell the user about what happens when an action is performed?

- Anticipating and mitigating errors: What kind of constraints are put in place to prevent errors? In the case of an error, what kind of error messages are provided for the user to correct the problem?

- Considering system feedback and response time: How long does it take between an action being performed (for example: clicking a button) and the product responding? What kind of feedback is given to the user once the action is performed?

- Strategically thinking about each element: Are you following standards? (Fitt's law, metaphors, having an understanding of how elements function)

- Simplifying for learnability: Is the format as simplified as possible for the users? (This includes decluttering, number of choices, removing complexity, using familiar user flow patterns)
