Designing is not just drawing with no intention, but design itself is so meaningful
Design’s world just like human’s world or we can say design’s world is the creation of human behavior from human’s world, we say it as human center art. That assumption could be put on UI/UX design as well. Here’s some law that we should pay attention of, because it would make different result of our design as UI/UX designer and researcher. I already packed it, so I hope it’s easy to understand.
Aesthetic-Usability Effect Law
Users believe that designs that look good also work well. It is linear with the theory of positive effect and it’s influence on cognition. Relationship effect between products and users has good side if that is good relationship.
Application:
Complexity
Color
Work well for long term success
Hick’s Law
Lots of option make the costumers browse, but fewer choices got them to buy it is call a Paradox of choices that say, less is more — too much choices is stressful. As designer we need to remember that user’s time is precious and user is not obligated to stay on our site.
Fitt’s Law
Human motor system need time required to move a target depends on distance to it. Instance, Interactive buttons should have size at least 1 x 1 cm to prevent fat finger errors. The movement it could be categorized as initial movement (fast) and final movement (slow) to recognize is it true button or not. Here’s a few tips to make interactive elements:
Pay attention of the size, at least 1 x 1 cm.
Mind the gap between elements.
Highlight or make it as oversized button if it important button.
Icon need label, make the area large
Label must be present along side an icon.
Goal-Gradient Effect
People only remember three types of experience
Good experience
Worst experience
End experience
In UI/UX field, this law come out as
Progress visualization
Fun activity and rewarding
Activity Tracking
Jakob’s Law
This law said that make a interface look like what the user familiar with, because it’s decrease the effort which is its good step to attract them.
Miller’s Law
Research says that the average people can only keep 7 (plus minus 2) items in their working memory. Things you should pay attention more are:
Don’t use unnecessary design
Organize content into smaller group
Avoid too many choices
Strive for readability
Use iconography
Parkinson’s Law
“We should be careful not to exhaust our available time on things that are merely good and leave little time for that which the best”
Tips: Set time as the weight of that task
Doherty Treshold
The art of understanding computer science, a computer and users interact at pace (<400 ms) to keep productivity and users attention. One of the solution is use animation to engage people while the processing happening in the background. Another solution is add progress bar to know how much time that they should wait, make it more tolerable.
Occam’s Razor
Less elements is good but we should prioritize the function, is it give bad impact to work flow or not? So, instead of decreasing elements we should analyze it first as a functionality. Consider completion only when no additional items can be removed.
Pareto Principle
The rules of 80/20
As a designer we should know what our priority to make an impact 80% of our 20% effort. So, we could bring the largest benefit to the most users.
Postel’s Law
Research result it shouldn’t be so objective full to user, a lot of consideration must be think of. Translating the input to your requirement to get the wonderful insights.
The Rule of Least Power
“Don’t use the advance technology for a little output.”
Example is use simple program languages for build simple output.
Law of Common Region
To know user behavior and how they finish the task, grouping elements is the solution. The goal of grouping element is to make the flow easy to do, not confusing them.
Tips
Make a section
Adding border
Defining the background such as color
Law of proximity
“The element that are closed each other consider as a group”
Law of Pragnanz
“People will perceive and interpret ambiguous and complexity as the simplest form possible, because that only use least cognitive effort.”
Peak End Rule
“Most people look at the end or peak not average moment they’ve been through”
Tips
Prioritize
Identify the time when the product at the good work
Serial Position Effect
Positioning is important, the best place to users easy to remember is first and last items
Example is navigation bar, far left or far right.
Von Restroff Effect
“The unique one always stand-out”
Zeigarnik Effect
“People remember uncompleted task better than completed task”
This article actually as my note when I learnt about design principle at UI/UX field, but I think I should share it so everyone could learn it too.
Lastly, I have quote that said “The best design is design that could answer human problem and communicate it to them”.
