- Proper Amount of Information:
- Too much information on a screen can be confusing because it competes for attention.
- It makes visual searches longer and makes it harder to see a clear structure.
- Too little information is inefficient and might burden memory if spread across multiple screens.
- Present All Necessary Information:
- Ideally, provide all the needed information for an action or decision on one screen.
- Avoid relying on memory for information spread across different screens.
- Screen Density:
- Density calculates how much information is on the screen.
- It’s linked to complexity, as both measure “how much is there.”
- Two types of density:
- Overall Density: Measures the percentage of the entire screen filled with data.
- Local Density: Measures how tightly packed the screen is.
