Final answer:
To reduce the need for memorizing commands in interactive applications, providing consistent command structures is key, as it makes command logic predictable and user interfaces intuitive.
Step-by-step explanation:
To reduce the need to memorize commands in interactive applications, we should provide consistent command structures. This approach allows users to learn the logic and pattern behind the commands, making it easier to predict and remember them. Unlike increasing the complexity or randomizing sequences, which would make memorization more difficult, consistency helps in building a user-friendly interface where commands are intuitive. Furthermore, eliminating the user interface is not a viable solution, as interfaces offer visual cues and interactions that reinforce command recall. In the case of modeling in scientific research, models are simpler to analyze than the complex reality they represent, which is why scientists may use them instead of analyzing the real system directly.
