A principle that states that users expect websites to work the same way as other websites or applications
Who is the prominent user experience (UX) researcher that Jakob's Law is named after?
Jakob Nielsen
Why do users expect your website or application to work the same way as other websites or applications?
Because users are already familiar with certain design patterns and user interface elements
What is the main benefit of simplifying the design of a website?
It makes it easier for users to navigate and find the information they need

To ensure that data is transmitted correctly
What is the purpose of being conservative in what you send, according to Postel's Law?
To ensure that data is transmitted correctly and can be interpreted by other systems
What is the 'Law of Proximity' in the context of Gestalt Principles?
Elements that are close together are perceived as a group
What is the purpose of the 'Law of Figure-Ground' in the context of UX design?
To separate visual information into a foreground and a background
What is the main idea behind the Gestalt Principles?
How humans perceive visual elements and group them together
What is the purpose of grouping related items together visually in UX design?
To help users understand the relationships between different elements
What is the 'Law of Continuity' in the context of Gestalt Principles?
Elements that are arranged in a smooth, continuous line or curve are perceived as a group
What is the purpose of being liberal in what you accept, according to Postel's Law?
To allow for variations in interpretation and help ensure that communication is not disrupted
Study Notes
UX Design Laws
- User experience (UX) is the overall experience a person has when interacting with a product or service, encompassing everything from usability to emotions and attitudes.
- UX laws are a set of principles that guide the design of user experiences, ensuring digital products and services are intuitive, easy to use, and meet user needs.
Hick's Law
- States that the time it takes for a person to make a decision increases with the number of options available.
- Too many choices can lead to frustration or indecision, and designers can reduce cognitive load by simplifying interfaces and minimizing options.
- The more options presented, the longer it takes to make a decision, as the brain has to process each option.
- Implications for website design: simplifying design can make it easier for users to navigate and find information.
The Law of Fitts
- States that the time it takes to move a pointer to a target depends on the size of the target and the distance to it.
- Larger targets that are closer to the user are easier to click on than smaller targets that are farther away.
- Movement time is influenced by the distance between the starting point and the target point, as well as the target size.
- The Fitts' Law equation describes the relationship between movement time, distance, and target size: MT = a + b log2(2D/W).
Jakob's Law
- States that users spend most of their time using other websites or applications, and expect your website or application to work the same way.
- Users expect consistency in design patterns and user interface elements, and deviation from established conventions can lead to confusion.
- Consistency is key, including consistent navigation, labeling, and design patterns.
- User testing is essential to ensure that design meets user expectations and is easy to use.
Miller's Law
- States that the average person can hold only 7 plus or minus 2 pieces of information in their working memory at any given time.
- Designers should limit the number of items presented to the user to no more than 7, in order to avoid overwhelming the user's working memory.
- Implications for navigation menus, forms, and chunking: grouping information into smaller, more manageable chunks.
Postel's Law
- States that "be conservative in what you send, be liberal in what you accept".
- Being conservative in sending data means conforming to established standards and protocols.
- Being liberal in accepting data means being flexible in interpreting and handling variations in communication.
Gestalt Principles
- Describe how humans perceive visual elements and group them together.
- Objects that are close to each other are perceived as related.
- Implications for UX design: grouping related items together visually, such as navigation items and form fields.
- Six laws of Gestalt principles:
- Law of Proximity: Elements that are close together are perceived as a group.
- Law of Similarity: Elements that are similar in appearance are perceived as a group.
- Law of Closure: Our brains fill in missing gaps to create a complete image or object.
- Law of Continuity: Elements that are arranged in a smooth, continuous line or curve are perceived as a group.
- Law of Figure-Ground: Our brains separate visual information into a foreground and a background.
- Law of Symmetry: Our brains perceive symmetrical objects as complete figures.
This lecture covers fundamental principles guiding user experience design, including Hick's Law, Fitts's Law, Jakob's Law, Postel's Law, Miller's Law, and Gestalt Principles.
