Interaction design: The key to measuring the quality of interactive design

Article Description: attention and interaction design.

People-oriented design, we must consider the ordinary people in the general task of the implementation of the tolerance problem. Because the person's energy is limited, again strong demand, powerless to complete is also in vain. The effective conversion rate of energy is the key point to measure the quality of interactive design.

1. Formula

Energy generally consists of mental and physical makeup. For Internet products, mental habitat (the physical consumption of non-production sites is very low). And the composition of brain is divided into attention, understanding and memory. In this paper, we will try to analyze the characteristics and precautions of interactive design with attention as an example.

Attention itself can be concentrated, dispersed and transferred. Concentration generally out of clear demand, potential interest; dispersion is due to information interference and uncontrollable time; The shift generally occurs in the stage of demand exploration.

The site information structure within the elements of the unit, plus each page of all visual elements, you can get the total attention of the site "item." Users use these items to meet their own needs, and interactive design is the description of these items, organizers. If we assume that attention is limited, then each item should be given a fixed value. Plus because of individual differences, the level of interest and demand is different, we get the following formula

In addition to the "demand intensity", the "interest concentration", "length of Time" and "number of visual items" three values, interaction design can have an impact on it.

2. Concentration of interest

User's operating habits and interaction expectations on the Web have their own unique mental models, sometimes different from real life. For example, in reality, our request for pictures is just to look, hang on the wall or hold it in hand. And the Internet is first a hyper-link integration platform, followed by a display platform. So the picture above is also given to the link's expectations. People's expectations of it have become richer. Therefore, giving pictures more interactive content can directly enhance the user's interest value.

The two typical design ideas for interest are that charts are better than tables, tables speak louder than texts, and physical and chemical design, including the copy of the object. It can be said that the more specific the object, the more people feel safe and cordial. and cordial and polite, in line with the laws of physics, the operation of timely feedback, to meet the emotional needs of the design, can add points for interest. Vice versa.

The unavailable state is not a good design, especially if the conditions for activating it are relatively long

It is based on people's yearning for the graphic, visual design will have an impact on the interactive design can not be underestimated. The individual thinks that in the interactive design the part that is related to the interest, the vision should become the important reference factor. For example, the color of controls, the layout of copywriting, the way links are displayed, and so on.

3. Length of time

An important difference between the design of Internet interaction and the interaction design of daily necessities is the concept of time. In reality, time is an important cost, often affecting people's decisions and emotions. In the network environment, physical and interpersonal burdens are fully weakened, most of the time is only personal mental costs. If demand and interest converge well, time can even be overlooked.

Not to mention the extreme example of the game, the ordinary product loading time for example, if the interest-oriented processing (progress bar and micro-funnel, such as time calculation tools belong to this column, and preload is a demand convergence), users will not produce too much complaining. It involves searching, searching, browsing, and so on, and the user is almost concerned with the item rather than the time.

It should be noted that the process of a relatively strong task, start and end must have a clear hint to prevent attention overflow, resulting in unnecessary energy loss.

4. Number of visible items

In general, the task of interactive design is the design. such as the determination of information structure, element Dictionary, visual form and so on. Why do you say the larger the number of visual items, the smaller the attention? This is determined by the cognitive characteristics. The more options, the longer the process, the more people need to consume understanding. There is a greater pressure on understanding, which requires recourse to inward attention, the task attribute of attention, to the logical attribute, resulting in a decrease in the ability to interact. Combined with the expectation of the time spent on attention transfer, the demanding (physical) of the mouse and keyboard, people generally resent the lengthy forms, page jumps, and so on. Then there appears the interactive form of "response expansion", "Pop-up bubble", "Window", "label" and so on.

The organization and presentation of items is a big issue

In addition to using good organization to "reduce" the number of visual items, element dictionaries, visual forms can also affect interest, use of interest to enhance attention. Take the element dictionary as an example, the function mainly plays in the key word. Like "I recommend to you" and "We listen Together" in the "Together", "You may like" and "friends also like" in the "Friends" and so on. Arabic numerals are significantly more attentive than Chinese numerals. The "Remove all" response rate is faster than "empty". If you do not consider the use of the environment, "delete John Weibo" and "Delete micro-blog", that effect is good?

5. Summary

Interaction design, as a process science, requires a certain amount of time and energy loss. From the Internet perspective, attention becomes particularly important because of the exclusion of physical factors. With the attention conversion rate as an opportunity, we can take the interactive design to the user experience design to advance one step.

The result of attention and understanding is memory, the effect of memory on interaction design, and the next time we communicate.
