100 Things Every Designer Needs to Know About People (Voices That Matter)

Don’t make assumptions. What is obvious to you as the designer may not be obvious to the people using what you’ve designed.

If you’re going to give an extrinsic reward, it will be more motivating if it is unexpected.

Choose a point size that is large enough for people of various ages to read comfortably.

Better yet, use short videos as examples.

If you have to make a trade-off on clicks versus thinking, use more clicks and less thinking.

Use stories as much as you can, even for what you think is factual information.

Use a font with a large x-height for online viewing so that the type will appear to be larger.

If you want people to remember something, then you have to go over it again and again. Practice really does make perfect.

Provide ample contrast between foreground and background. Black text on a white background is the most readable.
