User interactions are influenced by their previous experiences.
The Law of Past Experience (also know as the Law of Familiarity) refers to the principle that users bring with them knowledge and expectations from their previous interactions with interfaces, websites, or apps. When a design aligns with these past experiences, users can easily navigate your site or app. However, if it doesn’t, users might get confused or frustrated.
Background
The concept comes from the understanding that humans rely on patterns and familiarities. When we encounter something new, our brain automatically tries to relate it to something we already know. This is especially true in the digital world where consistency can lead to better user experience. If a user has spent years interacting with a particular type of interface or design, they will expect similar interfaces to function in the same way.
Law of Past Experience Design Example
Did you know there was actually a physical “floppy disk” we used to use?! This is the same floppy disk icon that’s often used to represent the “save” function in many apps and software. For many modern users, especially the younger generation, a floppy disk is an outdated technology they might have never used. However, because of its widespread use in past software designs, it’s become a universal symbol for saving work.
Design takeaways
- Consistency is Key: Ensure that design elements are consistent across different parts of the interface.
- Leverage Familiar Patterns: Use icons, symbols, and layouts that users are already familiar with.
- Educate When Deviating: If you’re introducing a new design pattern that deviates from the norm, ensure you provide guidance or tutorials.
- Test with Real Users: Always test your designs with real users to understand their past experiences and how they might influence interactions with your design.
