There isn’t a specific term or concept known as “UX law.” It’s possible that you may be referring to “UX principles” or “laws of UX,” which are guidelines and heuristics that inform the design of user experiences. These principles are derived from research, best practices, and observations about human behavior and cognition. They help UX designers create effective and user-centered interfaces. Here are some commonly recognized principles or “laws” of UX:
- Hick’s Law: This law states that the time it takes for a person to make a decision increases with the number of available options. It suggests that reducing complexity and providing clear choices can improve decision-making and user experience.
- Fitts’s Law: Fitts’s Law states that the time it takes to reach a target depends on the size of the target and its distance from the starting point. It emphasizes the importance of making interactive elements larger and placing them within easy reach to enhance usability.
- Jakob’s Law: Jakob’s Law states that users’ expectations are shaped by their experiences with other familiar interfaces. Designers should consider established design patterns and conventions to create interfaces that are intuitive and align with users’ mental models.
- Law of Proximity: The Law of Proximity states that items that are close to each other tend to be perceived as related or belonging to the same group. Designers can use this principle to visually group related elements and create meaningful relationships within the interface.
- Gestalt Principles: The Gestalt Principles, such as proximity, similarity, closure, and continuity, describe how humans perceive and organize visual information. Understanding these principles helps designers create interfaces that are visually cohesive and promote efficient information processing.
- Miller’s Law: Miller’s Law suggests that the average person can only hold around seven (plus or minus two) items in their working memory. Designers should consider this limitation when presenting information and break it down into smaller, more manageable chunks.
- Law of Prägnanz: The Law of Prägnanz, also known as the Law of Good Figure or the Law of Simplicity, states that people perceive and interpret ambiguous or complex stimuli in the simplest, most organized way possible. Designers should strive for simplicity, clarity, and visual hierarchy to aid users in quickly understanding and interpreting the interface.
These principles are not strict rules, but they provide valuable insights into human behavior and perception, allowing designers to create interfaces that are intuitive, efficient, and user-friendly.
