What Is Error and Types of Errors in Human-Computer Interaction (HCI)

Learn more about the nuances of what is error and types of errors in HCI (Human-Computer Interaction) with this video, expertly guided by Alan Dix and the Interaction Design Foundation (IxDF). This presentation delves into the Don Norman model to differentiate two primary categories of human errors: 'slips' and 'mistakes', essential concepts for anyone involved in UX design and HCI.

Alan Dix explains 'slips' as errors made during the execution phase despite correct intentions, and 'mistakes' as errors arising from incorrect goals or misunderstandings about system functionalities. This tutorial is packed with real-world examples that illustrate how these errors manifest during system use, including common scenarios encountered in email systems and recording tasks. The video offers actionable strategies to mitigate these errors by design, such as improving interface design to prevent slips and enhancing system feedback to correct misunderstandings, thereby reducing mistakes. These interventions aim to make systems more intuitive and forgiving, enhancing user satisfaction and reducing frustration.

Ideal for UX designers, HCI professionals, and anyone interested in understanding human errors in technology interactions, this tutorial emphasizes the importance of designing for error prevention. Learn from Alan Dix, a seasoned expert, as he provides insights on aligning system design with human behavior to minimize the frequency and impact of errors. By exploring the "types of errors in HCI," such as slips and mistakes, and discussing methods like interface adjustment and user education, this video is a crucial resource for improving user experience design. Engage with content that not only educates but also equips you to create more user-friendly and error-resistant systems.
