The importance of feedback loops from "summary" of The Design of Everyday Things Indian ed. by Don Norman
Feedback loops are crucial in the design of everyday things. They provide users with information about the results of their actions, helping them understand the system better. This feedback can be in the form of sounds, lights, or physical sensations that inform users about the status of the system. For instance, a clicking sound when a button is pressed indicates that the action was successful, while an error message on a screen informs users about a mistake they need to correct. Feedback loops play a significant role in simplifying the interaction between users and systems. By providing immediate and relevant information, feedback helps users make informed decisions and take appropriate actions. This feedback can guide users through complex tasks by breaking them down into smaller, more manageable steps. For example, a progress bar that fills up as a file is being downloaded gives users a sense of how much longer they need to wait, making the process less frustrating. Moreover, feedback loops enhance the clarity of the user experience by reducing uncertainty and ambiguity. Clear and consistent feedback helps users understand the cause-and-effect relationship between their actions and the system's response. This transparency builds trust and confidence in the system, encouraging users to explore its capabilities further. For instance, a thermostat that displays the current temperature and the desired setting helps users adjust the settings accordingly. Feedback loops also promote coherence in the user interface by creating a seamless flow of information between users and systems. By providing continuous feedback, systems can adapt to users' preferences and behaviors, making the interaction more intuitive and efficient. This adaptability allows users to learn and improve their skills over time, leading to a more satisfying user experience. For example, predictive text input on a smartphone learns from users' typing patterns to suggest relevant words and phrases.- Feedback loops are a fundamental aspect of design that enhances the simplicity, clarity, and coherence of everyday things. By providing timely and relevant information, feedback helps users navigate systems more effectively and confidently. Designers must prioritize feedback mechanisms in their designs to create intuitive and satisfying user experiences.
