Design should take into account the user's mental workload from "summary" of The Design of Everyday Things by Don Norman
Designers must consider the mental workload of users when creating products. This is crucial because users have limited cognitive resources, and if a design places too much demand on their mental capabilities, they will become overwhelmed. When users are overwhelmed, they are more likely to make errors and experience frustration. To minimize mental workload, designers should strive for simplicity in their designs. Simplicity means eliminating unnecessary complexity and making the interaction as straightforward as possible. By reducing the number of steps required to complete a task, designers can help users conserve mental energy and focus on the task at hand. Clarity and coherence are also essential aspects of reducing mental workload. Users should be able to easily understand the purpose of a product and how to use it. Clear feedback and guidance help users make sense of the system and reduce the cognitive effort required to operate it. Logical sequencing is another critical factor in designing for mental workload. Information and actions should be presented in a logical order that makes sense to the user. This helps users anticipate what will happen next and reduces the need to constantly reorient themselves. Transition words and phrases can also aid in reducing mental workload by guiding users through the interaction. Consistent use of language and visual cues helps users navigate the system more efficiently. Maintaining consistency in tone and style throughout the design is important for reducing mental workload. Inconsistencies can confuse users and force them to spend extra mental effort trying to make sense of the design. Grammar and syntax should be clear and straightforward, helping users quickly understand instructions and feedback. Confusing language or poorly structured sentences can increase mental workload and lead to user errors. Contextual understanding is crucial for designers to create products that align with users' mental models. By considering the way users think and perceive the world, designers can create intuitive designs that minimize cognitive strain.- Designing with the user's mental workload in mind is essential for creating products that are intuitive, easy to use, and enjoyable. By simplifying interactions, providing clear guidance, and maintaining consistency, designers can help users conserve mental energy and focus on achieving their goals.
