Beyond Intuition: The Laws That Guide Exceptional User Experience Part-II

Doherty Threshold: User Engagement

The Doherty Threshold, also known as the “Goldilocks Zone,” suggests that there’s an ideal response time for computer systems and applications to keep users engaged. If a system’s response is too fast, users may not feel in control; if it’s too slow, they may become frustrated.

UX designers aim to optimize response times in digital interfaces to keep users engaged and satisfied. For example, responsive design and efficient loading times contribute to meeting this threshold.

Murphy’s Law: Error handling

Murphy’s Law is a general principle stating that “anything that can go wrong will go wrong.” In UX, this law reminds designers to anticipate and plan for errors and unexpected user behaviors.

Designers incorporate error-handling mechanisms such as informative error messages, clear instructions, and intuitive navigation paths to help users recover from mistakes or unexpected situations gracefully.

Von Restorff Effect: Emphasizing the unusual

The Von Restorff Effect, also known as the “isolation effect,” suggests that when multiple similar items are presented, the one that is different or unique tends to stand out and be remembered more.

UX designers can use this principle to draw attention to critical elements, such as important messages or calls to action, by making them visually distinct from the surrounding content.

Tesler’s Law (Law of Conservation of Complexity): Emphasizing the unusual

Tesler’s Law suggests that complexity in a system remains constant; it simply shifts between the user and the designer. This means that while users may not see complexity in the interface, it’s often managed behind the scenes.

Designers aim to minimize user-facing complexity by simplifying interfaces while maintaining necessary functionality. This ensures that users have a straightforward experience, even if the underlying system is complex.

Progressive Disclosure: Guiding User Exploration

Progressive Disclosure involves revealing information gradually, starting with essential information and providing more details as needed. When the users are bombarded with excessive information all at once, their cognitive load increases. The higher the cognitive load will higher the frustration and decrease the user experience. By presenting information gradually, the designer reduces this load and makes the experience more manageable.

UX designers use progressive disclosure to guide users through complex interfaces or workflows. For example, in a settings menu, showing basic options first and allowing users to delve deeper if needed simplifies the experience.

In conclusion, we can say- “The best products don’t focus on features, they focus on clarity.”- Jon Belt

The above statement resonates deeply with the core principles and laws of UX. Clarity can only be achieved if the designers and product owners apply these laws to their products. These Laws not only simplify user experience but also boost trust, enhance satisfaction, and ultimately determine the success and longevity of a product in the marketplace.
