Human Computer Interaction Questions
Human error in HCI refers to mistakes or incorrect actions made by users while interacting with computer systems or interfaces. It occurs when users deviate from the intended or expected actions, leading to undesired outcomes or errors. Human error can be categorized into different types, such as slips, lapses, mistakes, and violations.
Slips are unintentional errors that occur due to the user's failure to execute a correct action. For example, pressing the wrong button or selecting the wrong option on a menu.
Lapses, on the other hand, are also unintentional errors but occur due to the user's failure to remember or recall the correct action. For instance, forgetting to save a document before closing it.
Mistakes are cognitive errors that happen when users have incorrect mental models or understanding of how a system works. This can lead to incorrect actions or decisions. For example, misunderstanding the purpose of a specific feature and using it inappropriately.
Violations occur when users intentionally deviate from the prescribed rules or guidelines of a system. This can be due to various reasons, such as time pressure, lack of knowledge, or personal preferences. Violations can lead to errors or system failures.
Understanding human error in HCI is crucial for designing user-friendly interfaces and systems. By considering potential sources of human error, designers can implement strategies to prevent or mitigate errors, such as providing clear instructions, feedback, and error prevention mechanisms.
