UX principles explained with illustrations.

User Experience (UX) gives life to a user’s digital journey. It is the enhanced pleasure, comfort and ease of using an app or website. UX design reinforces the mutual interactivity between the user and the interface. It integrates human psychology and emotions to heighten user satisfaction and provide a delightful product experience.

UX is an exalting design field in today’s digital world. Let us look into some vital theories which fortify the human-computer interaction through UX design.

Hick’s Law

Making choice easier for users

Hick’s law emphasizes on breaking down complex processes into more simplified and manageable steps. It pinpoints that the time taken to make a decision increases as the number of choices increase.Thus, users can become irritated, confused and leave the website. As a designer, you must focus on reducing the time taken by the user in taking decisions by providing minimal options at a time.

For example, you can remove unnecessary links, buttons, and text to ensure that the user is able to fulfill his task quickly. You can also shorten long lists and reduce the options where possible.

In a nutshell, Hick’s law is about keeping things simple and short to provide a high-quality user experience.

Fitt’s Law

Size and distance matters

Fitt’s Law describes that the bigger an object and the closer it is to the user, the less is the time taken to reach the targeted area.Accordingly, this law states that there are relationships between the amount of time taken by the user to move his pointer to the required element ,the size and the located distance of the element.You have to be vigilant of these factors when designing the interface.

For example, enlarging the size of the target (eg: button) makes it easier to click and increases the convenience of use.You can place frequently used buttons and links next to each other to speed up the interaction time and avoid muscular tension which can be caused when the objects are distributed.

Implementing this law cleverly, can give user’s a productive experience.

Jakob’s Law

Familiarity principle

Users browse several sites and would prefer your site to work in a similar way as other sites.Their past experiences in different sites manipulate them to create a mental model of what they want to see and where they want to see it.So, familiar design patterns make the user’s learning process easier.

It is better to have a familiar-looking interface for your site where components such as the next buttons are located on the bottom right corner, and links are highlighted from normal text. It is not necessary to relocate these standardized components to design creatively. Such changes of common patterns in websites can make your interface hard to work with creating an uncomfortable environment for the user.

Thus, you have to focus on the usability and familiar access pattern of the site when adding creative components.

Law of Proximity

Closer objects are related

This law explains how the human mind perceives objects that are grouped together as objects related to one another. The law of proximity helps the designer to organize the interface for users to easily scan and understand the information.

So when designing user interfaces that contain varieties of content, you can position similar contents close to one another. White spaces can be placed between groups to further enhance the user’s ability to differentiate the groups of content.

This law can support in designing user-friendly interfaces.

Law of Prägnanz

Law of simplicity

As humans we prefer things that are simple, clear and ordered as they are easier to process.Our eyes are clever enough to simplify complex objects and reduce information overload.The human mind is capable of identifying individual parts that makes up a whole object.

You can apply this law when designing your websites so that the users are at ease when they are able to interpret complex objects in the simplest form possible.

So instinctually, the users feel safer, comfortable and are able to understand and process information quickly and easily.

Aesthetic Effect

Attract attention

The human psychology spontaneously perceives that attractive things are easier to work with. Users are strongly influenced by the aesthetic appearance of any interface that appeals to their attention. Thus it is important to create a positive first impression of your website. A pleasant appearance can mask minor issues of your site. A visually appealing site has to be orderly, well designed and professional to attract users.

Mostly what users perceive as appealing depends on their cultural background and geographical regions.

So it is wise to design interfaces with a thorough study of the user’s geographical background and culture to create a user-friendly and appealing interface.

Doherty’s threshold

Respond quickly

Time is very precious to users. A system’s response time is very crucial in enhancing user experience. Users like to feel that their actions are quickly causing something to happen on the screen. A standard response time of less than 400 milliseconds is essential to create an efficient and effective interaction between the user and the interface.

So, the user feels that the system is responding instantly and thus their attention will be focused on the task at hand. Delayed responses distract users and annoy them. In case the system is unable to give an immediate response- continuous feedback and progress indicators should be provided to users, to assure them that the system is functioning well.

Timely response is a fundamental need for quality user experience.

Serial Position Effect

Respond quickly

This serial position effect is a theory built with regard to man’s ability to remember. Accordingly, it is said that man is able to remember the first and last contents in a serial list and is more likely to forget those in the middle of the list. So keeping this in mind, you must understand how to manipulate information and reduce stress on a user’s memory.

For example, you can highlight important information at the beginning and end while placing the less important details in the middle. You can also use cues or identification indicators such as arrows, transitions, and sounds to help the user remember. Maintain only task related information within the user interface.

A vibrant knowledge of the serial position effect can aid in creating powerful interfaces.

Peak–End Rule

Blissful experiences

This is one of the most significant rule in UX designing.It is based on what people remember and experience from their most intense moments- it may be positive or negative.Moreover people tend to recall negative experiences than positive ones.

So as designers, you have to focus on making users feel and cherish pleasant experiences on their journey within our site.You can get feedback from users and design peaking joyful experiences while avoiding negative events.

In conclusion, it is quite clear, how every minute human psychological and mental factor contributes to creating ideal user experiences. ”Design isn’t finished until somebody is using it”, such is the significance of human interaction in creating a delightful UX. As a UX designer, you have a wonderful opportunity to make a difference, and that’s what makes it an interesting career.
