Using typefaces with distinct characters can help users easily differentiate alphanumeric data. Choose typefaces that pass the I-L-1 test for data tables and information seen at-a-glance.
Users perceive interface design elements that differentiate the foreground (figure) from the background (ground) as something to focus on or interact with.
Things that move in synch are perceived as belonging to the same group and being different than other screen elements that stay put or move differently.
Visual design elements that are connected (for example, by a line) are seen as belonging together. This principle is strong enough to overrule small differences between the items.
Visual-design principles can be applied consistently throughout the process of creating a polished UX map. Start by choosing a tool, then create a visual system, establish the basic layout, and finally add content and make adjustments.
UI elements that are close together are perceived as belonging together, whereas users think that things that are apart play different roles in the interaction.
User interface elements that share one or more traits (such as shape, color, size, etc.) will be seen by users as being similar and belonging together.
To design accessible visuals, account for color contrast, don’t rely on color alone, make interactive elements easy to identify, provide useful alternative text for images, and test your visuals with real users.
The gestalt principles for visual perception make users see some graphical user interface design elements as parts of a whole, and others as being separate, and thus different.
In application design, prevent users from being overwhelmed by putting things in predictable places, using a clear visual hierarchy, and taking advantage of progressive disclosure.
Visual hierarchy can help users decide where to look in a user interface: what's most important can be shown by color and size, and what things belong together can be shown by proximity and common regions.
Grids help designers create cohesive layouts, allowing end users to easily scan and use interfaces. A good grid adapts to various screen sizes and orientations, ensuring consistency across platforms.
When choosing typography to use in designs, narrow down your options by understanding the most common classifications, looking for typefaces with multiple variations and distinct characters, and pairing typefaces together with consistency and readability in mind.
