What is the goal to achieve with the wallboard ? Less is more. Achieve the most synthetic and efficient presentation possible of the desired information. It is interesting to familiarize yourself with the main principles of UX design, which are often summarized in 5 main “laws”:
1. Complexity : Miller’s Law
The law : an individual can only “process” a limited number of visual elements: 7 “plus or minus 2” (therefore between 5 and 9 elements).
The application: Less is more, limit the amount of information on your screen
2. Ease: Hick’s Law
The law : Logically linked to the previous one, Hick’s law states that the time required to perform a task increases with the number and complexity of the choices to be made.
The application: frame the information reading grid as much as possible, and always choose the formatting that is most immediately understandable
3. Familiarity: Jakob’s Law
The law :Netflix, Amazon, Blablacar… we homo numeréricus are used to these interfaces that we use every day. We like stable cues, and more easily use visual models to which we are accustomed
The application: don’t reinvent the wheel! Base your mockup on proven designs
4. Position: Proximity’s law
The law : nearby visual elements (side by side, above-below…) tend to be “grouped” in the user’s mind.
The application: use zoning to group together indicators that “work” together in the same are of your screen
5. Distinction : Von Restroff’s Law
The law : in a set of visually similar elements, the one that differs the most will be seen the most, and better remembered.
The application:is there a more important KPI or OKR than everything else? Treat it differently from others (color, size, animation …)
