Gestalt Principles
Important set of principles. To made your interface more simple and experience better…
Weber’s Law
When we redesign a product, we should think about how the users adapt to the changes. Usually, if your product has a drastic change, no matter how good the new design is, the users would still think the old one is better. This is a natural human behaviour.
Status Quo Bias
As humans, we rely on our emotions and experiences from our past, in order to make decisions faster. We imprint past decisions, which was deemed successful, as shortcuts in our brains…
Recognition over Recall
Asking users to name 3 things from memory consumes remarkably more brain energy than if we ask users to select 3 things from a predefined list. Every time we make users think, there is a considerable chance we will lose them and they will drop out…
Progressive Learning
We should allow novice users to learn progressively, how to use the user interface. Here, you need to lay out a clear learning path for users, one that allows them to start with basic skills and move on to something more advanced step by step, in increments.
Past experiences
“Elements tend to be perceived according to an observer’s past experience.”
Occam’s Razor
Occam’s Razor put simply, states that “the simplest solution is almost always the best.” With the flexibility and power of the web and our design tools, it is easy to get carried away. The result is a very complicated site or design that may have a lot of functionality and information, but is difficult to use, build and maintain.
Mental Models
The law states that it is significantly easier for users to understand and learn something new if they can model it off of something they already understand…
Law of Common Region
Elements tend to be perceived into groups if they are sharing an area with a clearly defined boundary.
Law of Prägnanz
People will perceive and interpret ambiguous or complex images as the simplest form possible, because it is the interpretation that requires the least cognitive effort of us.
Jakob’s law
Jakob’s law was invented by Jakob Neilsen, a user advocate. This law states that your users prefer your website to work in the same way as other websites…
Instant Expertise
Your interface you should take advantage of the user existing skills. If users can apply skills they have from other areas of their lives, you’ll save them the trouble of learning something completely new…
Hick’s Law
Law states that with every additional choice the time it will take for one to make a selection increases. In short, the more options your website has the more difficult it will be to use…
Fitts-Law
Fitts’ Law can be described as “The time required to move to a target is a function of the target size and distance to the target.”
Doherty Threshold
Productivity soars when a computer and its users interact at a pace (<400ms) that ensures that neither has to wait on the other.
Direct Interaction
An interface should imitate the user’s interaction with the physical world by having a direct correlation between user action and interface reaction.
Completion
If your application is geared toward a purpose with an end goal, you can utilize the fact that our need for closure drive us toward a well defined end-goal…
Cognitive load
If users find interaction with an interface difficult, their mental effort or cognitive load is high. Users don’t want keep thinking about how to manipulate the interface…
Authority
People, who identify with authority figures, trust their taste and often believe that it fits their own – or at least they wish it did…
Appropriate challenges
If we give new users a task that is too hard, they are going to feel stress and anxiety. If we give users a challenge that is too easy, they will feel bored…
80 / 20 Rule
The pareto principal stipulates that 80% of outputs in a complex system are caused by 20% of total inputs. Explained simply, a large percentage of outcomes are caused by a small percentage of inputs (the actual numbers are not always 80/20.) What does this mean for web design? Lots of things.
