Principles of User Interface Design
“To design is much more than simply to assemble, to order, or even to edit; it’s to add value and meaning, to illuminate, to simplify, to clarify, to modify, to dignify, to dramatize, to persuade, and perhaps even to amuse.” — Paul Rand
Clarity
Clarity is the most important aspect of any user interface. But, to be effective, people must be able to recognise it. They must understand why they would use it and what it’s helping them interact with. Users will foresee what will happen when they use it, and then successfully interact with it. There’s no room for confusion. Clarity encourages confidence which leads to further use. One hundred clear screens is preferable to a single cluttered one.
Interfaces exist to allow interaction
Interfaces exist to allow interaction between humans and the digital world. They help us clarify, manage expectations, and access services. The act of designing interfaces is not art, it’s utilitarian (designed to be useful or practical rather than attractive). They need to do their job effectively. However, the best interfaces can inspire, evoke, mystify, and intensify our relationship with the world.
Conserve attention at all costs
We live in a world of distractions. It’s hard to read in peace without something trying to interrupt us and direct our attention elsewhere. Attention is precious.
Don’t litter the side of your screen with material, it’s a distraction. Remember why the screen exists in the first place. If someone is reading, let them finish reading before showing that advertisement (if absolutely necessary). Respect attention and your readers be happier, and your results will be better. When engagement is the primary goal, attention becomes the prerequisite. Conserve it.
