We humans are created in such a way that we interact with everything, it could be any item, animal or a person. Either a woman interacting with her sister on the phone or interacting with computers at the office. When the quality of our interactions determines the quality of our lives then there should be a field that focuses on it, which happens to be interaction designs.

Psychology is the study of human minds, behaviour, and perceptions. Interaction design denotes the ways in which we communicate with the computers. So basically it’s Human-Computer interactions.

While using an application, psychology is the major aspect of user’s experience. Accordingly, we can make changes in the interface by knowing how the users appreciate those designs so we can create a more impactful interface.

The main psychology behind interaction design is to create such an interface which is smooth, attractive and user friendly at the same time.

Most importantly we should keep in mind the design we create is easy to use, compelling, intuitive and attractive at the same time.

How people really think….

 Law of proximity: When the objects are close or proximate to each other we consider them as a group. This happens because we humans are wired in such a fashion that we unite them and form a group altogether.

Similarly, when a UI is designed we should take into consideration that the user will put things together as if they are related to each other. Basically, law of proximity allows us the ability to read the words as a whole.

Progressive Disclosure: It refers to the increase of complexity in a progressive manner by keeping the UI clean and uncluttered as people get overwhelmed by too much of information.

Take for example, on the checkout page, instead of giving entire options for selecting different dates for delivery on the same screen, it redirects to a different one. This minimizes the clutter on the screen.

Minimizing Cognitive Load: When there is a mental effort which involves difficulty in the processing of a certain information it is defined as cognitive load. People have limited time to pay attention and if the load of the UI design is more then the user won’t stay there for long.

For example, too many options will repel the user making them feel more puzzled. So there should be definite options at a given point of time.

Visuals: To create a relationship between a user and a design, aesthetics and visual appearance plays an important role. The visuals like spacing between the words, the color of the UI design should be pleasant because of which pattern sticks with the user that it’s easy to use and intuitive.

When the interface is user-friendly then it becomes compellingly engaging and yet outstanding which is the only psychology behind interaction designs. Creating interaction designs with a human touch is the rightest way to build products, be it web or mobile. Because eventually, the purpose is communicating something with users in a simplistic and easily understandable manner.
