Although Nielsen's top ten availability principles do not have a direct visual impact on webpage design, they are an important guiding and reference basis for webpage interaction effects. They are worthy of in-depth study and research by every web designer.

Who is Nielsen?

 

Jakob Nielsen, a doctor of human-computer interaction, published the "Top Ten availability principles" in January 1, 1995 ". The web usability master has taught Web designers the relevant knowledge, although his views have not been readily accepted by all people, it may even bring about some controversy, but he still cannot shake the status of top leaders in the Web usability field.

 

A brief description of Nielsen's top ten availability principles

 

1. Visibility principle: the system status has feedback and the waiting time should be appropriate.

2. Environment apt principle: Use the user language instead of the developer language to stay close to the actual life rather than academic concepts

3. Withdrawal and redo principle: Operation errors can be rolled back

4. consistency principle: the expression of the same thing and similar operations should be consistent everywhere

5. Error Prevention principle: confirm the key operations and eliminate misoperations as soon as possible.

6. The principle of accessibility: recognition is better than memory, providing necessary information prompts (visible and easy to retrieve) to reduce the memory burden

7. flexible and efficient principle: you can design custom operation methods for new users and experts and adjust quick operations.

8. ease of use principle: reduce irrelevant information and reflect concise and aesthetic feeling

9. Fault Tolerance Principle: Give the user a clear error message and help the user easily recover from the error

10. human help principle: smooth application without document is certainly better. Generally, documents are necessary and also provide convenient retrieval functions. It is designed to describe User Tasks and list specific implementation steps, and not too long.

 

How to Use the Nielsen availability principle in design work?

 

1. Principle of visibility

The premise of guiding user behavior is to provide feedback and response to users in a timely manner. The visibility is especially reflected in users' clicks, scroll bars, waits, and even keyboard operations. A good experience will certainly give a real-time response.

 

2. Environment principles

This aspect is mainly manifested in the design of web icons and text, and it is possible to avoid some quasi-materialized or metaphor elements that need users' thinking. At the beginning of the design, we need to fully investigate the environment where the mainstream user groups are located and use the expressions that give them the most visibility.

 

3. Cancel redo Principle

Users may encounter misoperations when using the webpage. In this case, they should fully release the user's free control and give the user a bottle of "regret ".

 

4. consistency principle

This principle is well understood. In short, it is necessary to keep the design elements in the website consistent, reducing users' thinking time.

 

5. Error Prevention principle

Webpage Interaction designers should first imagine various "hand slides" during user operations. Therefore, measures to prevent user errors should be taken into consideration in design, such as restructuring webpages, or some special validation information to avoid unnecessary troubles caused by "Hand slide.

 

6. accessibility principle

This principle can be understood as the "Lenovo function" in the input method ". Imagine more possibilities for users and let users see what they want in the first place.

 

7. flexible and efficient principles

Today's Interaction designers are too many new users, so they even ignore the usage habits of middle-level users. Web designers must always remember that webpages are designed for the majority of users, so that they can be used flexibly and efficiently to be accepted by most users.

 

8. Yi Principle

Most users browse webpages in the form of a careless view, so it is very important to highlight the page focus and minimize irrelevant information.

 

9. Fault Tolerance principles

Fault Tolerance refers to a system error in the website itself. The website is obligated to minimize the impact on users. If some errors cannot be avoided, the creative 404 page users are also willing to accept the full order.

 

10. Principles of human assistance

The necessary help prompts and instructions can improve users' preference for the website. websites that are full of "human touch" will make users more interested in browsing.

 

AnyForWeb Summary

 

Nielsen's availability principle is of great help to Web Interaction designers and product managers. Interactive Design and user experience are a design form that focuses more on practice. Therefore, we constantly learn from our experiences and understand the specific characteristics of our industry, design Works will naturally be deeply rooted in the hearts of the people, and will be favored and praised by the user group.
