Human Centered Design Approach: Designing User Interface

Psychology knowledge helps to create the design which will make users perform the actions they are expected to such as making a purchase or contacting the team.

Various studies on human psychology have been undertaken while monitoring objects in the real world. A human-first approach to system design includes a variety of elements ranging from color to size, size to element position, and so on. This research will come in handy when developing an interface for a mobile app to a genuine industrial remote.

In this blog, we will discuss various effects that we should take into account while creating products. So the following is a brief description of the effects and its description.

Von Restorff Effect

The “isolation effect,” also known as the Von Restorff effect, states that when a group of homogenous items is given, the element that stands out is more likely to be recalled.

Zeigarnik Effect

The Zeigarnik effect, named after the Soviet psychologist who investigated it, refers to the human inclination to focus on unfinished activities rather than completed ones.

The psychological stress created by an unfinished condition aids in the recollection of any essential knowledge required to complete the activity.You might be eager to learn more because the story is unfinished. That’s the Zeigarnik effect at work. Another common application of the Zeigarnik effect is in teaching. Exams that demand preparation and cramming before the test are frequent for students to take in school.

Hick’s Law

Hick’s Law (or the Hick-Hyman Law) states that the more stimuli (or choices) users face, the longer it will take them to make a decision. This provides a difficulty for all sorts of designers, making it critical to provide the most usable range of alternatives to avoid aggravating the user. A user, for example, may have already formed a judgment before viewing the stimuli. In that case, the time it takes him or her to act is likely to be less than if he or she had not previously decided on a course of action.

Serial Position Effect

The serial position effect refers to the psychological propensity to recall the first and last items in a list better than the middle ones. The serial position effect is a type of cognitive bias that comprises the primacy and recency effects.For example, if a person makes a long grocery list, the serial position effect indicates that they will remember the first and last few items on the list but will struggle to recall what is in the middle.

Law of Common Region

The principle of common region says that items within a boundary are perceived as a group and assumed to share some common characteristic or functionality. The border surrounding the three center circles in this picture makes them look linked and as part of the same group. Example: In TV remote the numberpad is often has a boundary aroun itself.

Law of Proximity

The law of proximity defines how the human eye perceives visual relationships. When compared to elements that are distinct from each other, elements that are close to each other are regarded to be connected.

With these laws, we can help users save a lot of time and effort while learning new topics. These consequences and principles will also assist us in avoiding human mistake and creating a safe design for humans.
