-
We can only hold 4 items in our short-term memory, so limit the number of options you show at any time.
-
Focus on the top tasks, with the ability for the user to access other options of required.
Example menu or dropdown:
- Choice 1
- Choice 2
- Choice 3
- More...
- If you can't reduce the number of options, group them into chunks.
- Break more complex interactions into smaller steps.
- (don't forget to implement Limited Options and Chunking)
- Make the most common option the default.
- Make sure the most important information is the most prominent.
- Don't distract the user with secondary information.
