Flat UI Elements Attract Less Attention and Cause Uncertainty
If you're involved with web design, this study from Nielsen Norman Group has some good advice on your clickable elements.
"Using eyetracking equipment to track and visualize users’ eye movements across interfaces, we investigated how strong clickability signifiers (traditional clues such as underlined, blue text or a glossy 3D button) and weak or absent signifiers (for example, linked text styled as static text or a ghost button) impact the ways users process and understand web pages."
The post explains the study and results in great detail. In a nutshell:
- Design your sites with low information density.
- Stick with traditional and consistent layout.
- Place important interactive elements where they stand out from surrounding elements.
