Design is really an act of communication, which means having a deep understanding of the person with whom the designer is communicating. In this post we will have a look at the second principle: FEEDBACK It is explicit information about the impact of the action taken by the user. How to achieve it? Users should be kept informed about what’s going on. Keep continuous information about the results of their actions and the current state of the product (system). Avoid confusion in the mind of a user as to the state of the product, i.e., processing, loading, searching, uploading, etc., or some other state change. After an action has been executed, it should be easy to determine the new state. What other examples you can think of to help Feedback?
