Human Computer Interaction Questions
There are several different types of human errors in HCI, including:
1. Slip errors: These occur when a user intends to perform a certain action but makes a mistake in executing it. For example, pressing the wrong button on a touchscreen or clicking on the wrong link.
2. Mistake errors: These occur when a user has an incorrect understanding or mental model of how a system works, leading to errors in interaction. For example, misunderstanding the purpose of a certain feature or misinterpreting the meaning of an icon.
3. Capture errors: These occur when a user's attention is diverted or interrupted, causing them to forget or skip a step in a task. For example, being interrupted by a notification while filling out a form and forgetting to complete a required field.
4. Mode errors: These occur when a user unintentionally performs an action in the wrong mode or context. For example, typing a password in a username field or sending an email to the wrong recipient.
5. Data entry errors: These occur when a user makes mistakes while entering data, such as typing errors, transposing numbers, or selecting incorrect options from a dropdown menu.
6. Cognitive overload errors: These occur when a user is overwhelmed with too much information or too many options, leading to confusion and mistakes in decision-making or task completion.
7. Feedback errors: These occur when a user does not receive appropriate or timely feedback from the system, making it difficult for them to understand the outcome of their actions or to correct errors.
It is important for designers and developers to consider these types of human errors in HCI to create user-friendly interfaces and minimize the occurrence of errors.
