Website Design Analysis: Attention and Interaction Design

People-oriented design does not have to consider the endurance of ordinary people in general task execution. Because of limited human resources, strong demands, and inability to complete them. The effective conversion rate of energy is the key to measuring the interaction design quality.

1. Formula

Energy is generally composed of mental strength and physical strength. For Internet products, mental power is the top priority (non-production websites have low physical power consumption ). The mental power consists of attention, comprehension, and memory. This article will try to take attention as an example to analyze the characteristics and precautions of interactive design.

Attention itself can be concentrated, dispersed, and transferred. Concentrated generally out of clear needs and potential interests; scattered due to information interference and uncontrollable time; transfer generally occurs in the demand exploration phase.

In the unit of each element in the website information structure, with all the visual elements on each page, you can get the total attention "item" of the website ". Users use these items to meet their own needs. Interactive Design is the descriptive and organizer of these items. If attention is limited, the attention shared by each item should be fixed. In addition, because of individual differences, the levels of interests and needs are different, the following formula is obtained:

In addition to the "demand intensity", the "interest concentration", "time length", and "Number of visual items" values can affect the interaction design.

2. Interest concentration

Users' operation habits and interaction expectations on the Internet have their own unique mental models, sometimes different from those in real life. For example, in reality, we only need to look at the pictures, hanging them on a wall or holding them in our hands. The Internet is first a hyperlink integration platform, and secondly a presentation platform. Therefore, in addition to viewing the above images, the link is also given expectations. People expect more from it. Therefore, giving images more interactive content can directly increase user interest values.

Two typical designs of interest are: charts are better than tables, tables are better than texts, and quasi-materialized designs, including the text of anthropomorphic objects. The more specific the object is, the more secure and friendly people are. The friendly design that meets the laws of physics and provides timely feedback on operations and meets emotional needs can be used to add points of interest. And vice versa.

　　

 

The unavailable status is not a good design, especially when there are many conditions for activating it.

It is precisely based on people's yearning for graphics that visual design will have an undeniable impact on interactive design. I personally think that in interaction design, vision should be an important reference factor when it comes to interest-related parts. For example, the color of the control, text layout, and display of links.

3. length of time

An important difference between Internet Interaction Design and daily necessities interaction design lies in the concept of time between the two. In reality, time is an important cost and often affects people's decisions and emotions. In the network environment, physical strength and interpersonal burden are fully weakened, and most of the time is personal mental cost. If the demand and interest are well connected, the time can even be ignored.

Not to mention the extreme example of games, take the loading time of common products as an example. If the interest-oriented processing is proper (time computing tools such as progress bars and mini funnel belong to this column, and pre-loading is a requirement link), and users will not complain too much. In cases where attention is distributed, such as search, search, and browsing, users are concerned about items rather than time.

Note that there must be clear prompts at the beginning and end of a task with a strong flow to prevent attention overflow and unnecessary energy consumption.

4. Number of visual items

In general, the focus of interaction design is the item design. Such as determining the information structure, element dictionary, and visual form. Why is the larger the number of visual items, the smaller the attention? This is determined by cognitive features. The more options, the longer the steps, the more understandable people need. Understanding puts a lot of pressure on people. Therefore, you need to turn to inner attention and turn the attribute of attention tasks to logical attributes, reducing the interaction ability. In addition, people generally dislike lengthy forms, page jumps, and other situations due to the expectation of the time used for attention shifting, the demanding requirements for mouse and keyboard operations (physical strength. As a result, interactive forms such as "response expansion", "pop-up bubble", "pop-up window", and "tag" appear.

　　

 

Item organization and display method is a big topic

In addition to reducing the number of visual items in a good way of organization, element dictionaries and visual forms can also affect interest and use interest to increase attention. Taking the element dictionary as an example, it mainly plays a role in keywords. For example, "recommended for you" and "Let's listen together", "you may like" and "friends like. The attention of Arabic numerals is significantly higher than that of Chinese numerals. The "delete all" response speed is faster than "clear ". If you do not consider the use of the environment, "delete Michael's Weibo" and "delete Weibo", what will be better?

5. Summary

As a process science, interactive design requires a certain amount of time and energy. In the Internet field, attention becomes particularly important because physical factors are excluded. Taking the attention conversion rate as an opportunity, we can push the interaction design further to the user experience design.

The result of attention and understanding is memory. The impact of memory on interaction design will be discussed again next time.
