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.
