Learn Human Psychology and Behavior to Unlock Great User Experience
when I get to know some great influencing technique.
An Organization spend quite a lot of time on many research methods to understand human habits, behavior and needs. Thorough studies shows that there are many usage patterns that every customer goes through consciously or not while using any product whether digital or physical. Some exceptional personals have identified some human habits, behavior, needs and by addressing them they created some great UX Laws.
Fitt’s Law
The time to acquire a target is a function of the distance to and size of the target.
In 1954, Psychologist Paul Fitts, while examining the human motor system, discovered that the longer the distance to a target, and the smaller the target’s size, the longer it takes to acquire that target.
This law applies primarily to those elements, where the purpose is to find and select.
This is why the more important keys on a keyboard like Space, Enter and Shift are often larger than the rest of the keys.
These are some screen where the organization followed this UX law.
Hick’s Law
The time it takes to make a decision increases with the number and complexity of choices.
This means that the increase in time taken becomes less significant as the number of choices continues to increase. In other words, the risk of information saturation/overload rises when website visitors encounter too many options. This will almost certainly have a bearing on how quickly they abandon their user experience by leaving.
Some companies have this basic rule of UX engrave into their product very well.
Jocob’s Law
User spend most of their time on other sites. This means that users prefer your site to work the same way as all the other sites they already know.
It means that sometimes your urge to create something entirely unique and fancy might hamper the user experience simply because the user is not familiar with it.
The law was coined by Jakob Nielsen, director of Nielsen Norman group that he co-founded with Dr. Donald A Norman, Apple’s Vice-President of Research.
If you are ever going to set up e-commerce, the smartest option is to follow the structure of a similar ecommerce site.
Tesler’s Law
In any system, there’s a certain amount of complexity that cannot be reduced.
While working for Xerox PARC in the mid-1980s, Larry Tesler realized that the way users interact with applications was just as important as the application itself. The book Designing for Interaction by Dan Saffer, includes an interview with Larry Tesler that describes the law of conservation of complexity. The interview is popular among user experience and interaction designers. Larry Tesler argues that, in most cases, an engineer should spend an extra week reducing the complexity of an application versus making millions of users spend an extra minute using the program because of the extra complexity. However, Bruce Tognazzini proposes that people resist reductions to the amount of complexity in their lives. Thus, when an application is simplified, users begin attempting more complex tasks.
Von Restorff Effect
When multiple similar objects are present, people will likely remember the one that differs from the rest.
The theory was coined by German psychiatrist and pediatrician Hedwig von Restorff (1906–1962), who, in her 1933 study, found that when participants were presented with a list of categorically similar items with one distinctive, isolated item on the list, memory for the item was improved.
The law is mostly found in use, in pricing pages of products, where most of the pricing packages are same other than a few variations in the text. Companies use this to their advantage by highlighting their preferred pricing in a different color, shape, and size to bring focus onto that item.
There are an ocean like volume of Human behaviors and psychology to understand and work on them to deliver seamless and effortless USER EXPERIENCE.
