User Experience (UX) Laws to follow while Building a Digital Product

Good and Effective user experience plays a vital role for any of the product which is going to be Be launched in the market very soon, and designers from all over the world are now taking A step towards making their products better and better in usability by taking care of UX process very seriously. But there are some product designers and design researchers who are still learning the UX part and the UX Design Laws to keep their product usable & functional to make user spend more time using that mobile app.

As design is never ending process and new trends are keep coming, some products don’t make it to the market due to weak user experience resulting less user base for the products having a good concept and real world application. And to solve this UX problem there are several UX Design rules which one can use to make their product more usable and functional.

Here you will get to know about some UX rules in part 1.

1) Doherty Threshold

Productivity comes when a computer and its users interact at a speed, which ensures that there will not be any waiting on each other.

This law simply explains about providing system feedback within 400ms in order to keep users engaged and for increased productivity. If system responds slowly and taking more time to respond to user, it will make huge difference if its late by few hundred milliseconds.

I would like to give a Short Title to this : Rapid Response

2) Fitts’s Law

Time to access/acquire a target depends on the distance to the target and size of the target.

Fast movements and small targets results in greater error rate, so by applying fit’s law error rate can be reduced, Fitt’s law is widely applied in UX and UI Designs.

I would like to give a short title to this: Bigger & Closer the Target, Faster and Accurate the Action.

3) Hick’s Law

Decision making time increases with the complexity of choices.

In depth, more choices will make user to think longer for their selection and to make a decision. Simplify the choices for the user by breaking the complex tasks into small steps.

I would like to give a short title to this: Lesser the Complexity of Choice, Faster the Decision

4) Jakob’s Law

Every user will prefer that your site will work the way other websites work as they are familiar with the same design pattern. This means that for your product you can simplify the learning process for users by giving them the design patterns that they are used to see everyday.

I would like to give a short title to this: Familiar the pattern, More the usability

5) Law of Common Region

Elements will be grouped based on their behaviour if they are sharing an area with clearly defined boundary. Adding borders around the group of elements is easy way to show group separation from other region.

I would like to give a short title to this: Grouping objects by Boundary makes it easy to differentiate

6) Law of Prägnanz

User will understand and interpret complex images and shapes as the simplest possible form,

Appreciate if you like it! It will inspire me to do more of it 👏🏻
