1. Chunking: Chunking is a core strategy in UX design to manage limited working memory capacity. It consists of dividing information into smaller, more manageable chunks. For example, when designing login forms, input fields are limited to the most essential ones (username and password) to avoid overloading the user. Another clear example is the organization of navigation menus on websites, where elements are grouped into logical categories to facilitate navigation and reduce cognitive load.
2. Break Down Complex Tasks: For complex tasks, such as filling out a lengthy form or making an online purchase, breaking down the process into smaller, guided steps can significantly improve the user experience. This is known as “task breaking down” and helps users better handle information by not presenting it all at once.
3. Prioritise Content: It is essential to prioritise the graphic design email list most important information and present it prominently, while less crucial details can be revealed progressively through techniques such as progressive disclosure. This avoids overwhelming users with too much information at once and allows them to focus on the essentials at any given time.
4. Design Consistency: Maintaining consistent design patterns throughout the interface helps users quickly become familiar with the system and reduces cognitive load. Visual elements such as colors, fonts, and button styles should be uniform so that users don’t have to relearn how to interact with different parts of the system.
Practical Examples of Miller's Law
Amazon: Uses grouping to organize products into categories such as size, color, and features. This makes it easier for users to process and remember information, and make informed purchasing decisions.
Netflix: These streaming platforms group content recommendations into groups of around five to seven items. This helps users focus on a manageable set of options and makes decision-making easier.
Phone Numbers: A classic example of chunking is how phone numbers are presented. Breaking a long number into smaller segments makes it much easier to remember.
Conclusion
Miller’s Law underscores the importance of taking cognitive limitations into account when designing user interfaces. By applying principles such as grouping, content prioritization, task breakdown, and consistency in design, designers can create more intuitive and effective user experiences. These approaches not only improve usability but also increase user satisfaction and engagement. Understanding and applying Miller’s Law is crucial for any designer looking to create products that are easy to use and remember.
