10 Basic Interaction Design Principles to Boost the UX Design

Interaction Design, also known as Interactive Design (IxD), is the field to design the behavior of human-computer systems. As an interaction designer, we have to create the content and functions of products that are useful, easy to use, user-friendly, technically feasible, and of commercial interest. All of these are meant to improve the user experience. This article is going to talk about 10 basic principles of interaction design. Whether it is for the traditional graphical user interface or for any smart electronic devices, you can’t find it more useful.

1. Follow the user’s mental model

2. Meet the user’s needs

3. Consistency

If I told you this is a part of the poster from a famous company, do you know which one? Ok, a little hint for you, a beverage company. That’s right, it’s Coca Cola, here is the original poster.

Why the first picture does not appear Coca-Cola’s logo, product images, product introduction and any other information, and you still can assure it is Coca-Cola? Because behind Coca-Cola, there is a system called VI (Visual Identity System) that guides all of its external image design. The essence of VI is the visual consistency through a high degree, to guide users to be forcibly associated with some kind of visual information and a business, or products.

The white streamers in the picture are actually the auxiliary graphics commonly used in the Coca-Cola VI system. The graphics appear on almost all Coca-Cola promotional materials. The colors (including the red background), the shapes, and the twisted angles are exactly the same, so when we saw the similar graphics and color, our brain will generate reactions “This is Coca-Cola,”immediately. This action drastically reduces a lot of cognitive costs.

In a certain type of product or an industry that can form a wider range of “consistent” and get everyone’s recognition. At this time, consistency will become “standard.”

4. Less is More

In 1979, Sony found that most users had far greater demand for playing than recording, so they removed the traditional recording function of the recorder, and even removed the essential external speakers. Moreover, they put the remaining part in a small box with a stereo headset. This is the Walkman.

In 2007, Apple streamlined the phone’s keyboard, and even cut off the traditional physical keyboard. Then, they launched the iPhone. Well, you all know the following story.

5. Use simple language instead of technical terms

6. Design for functional than the aesthetic

When it comes to art, many people are put the “design” and “art” together. In my opinion, design is completely different from the art. To put it simply, art gives people a sense of “feeling”, while the designed products are helping people to solve problems and needs.

But we have to admit that sometimes a little “emotional feeling” is needed beyond function. So in many cases, if a small “design” can make the user smile, even if it is useless, it is also a “good design”. Look at New York subway poem below:


So tired.

If late,

Get fired.

Why bother?

Why the pain?

Just go home.

Do it again.

The poem, by Norman B. Colp, is aptly titled “The Commuter’s Lament. “As swarms of city-dwellers make their morning and evening trek between the high-traffic subway stations, they need only to glance up to see a sympathetic message.” Who can say that is a bad design?

7. Don’t make me think

8. Intuitive

9. Allow user making mistakes

10. Provide feedback

When the user performs certain operations in the human-computer interaction interface, the system must give the feedback to the user in the form of discoloration, shape change, vibration, light emission, etc. immediately. The purpose is to inform the user that their operation is known by the device. For example, the design of the control center of iOS 11 design will highlight the clicked icon by the user and use a different color to let the user know his operations is completed, and the un-clicked icon will be grayed out so that the user can see the feedback at a glance of his operation.
