Join Billy Hollis for an in-depth discussion in this video Cognitive design principles, part of UX Design for Developers.
- [Instructor] Let's move on to some design principles…concerning people's cognitive limitations…and capabilities.…It seems every developer thinks all buttons…should be the same size.…Almost every application I see does that.…Why?…There's no law about it.…Fitt's Law is a design principle…that suggests varying size of buttons…based on importance or frequency of use.…Bigger buttons are easier to find and use.…Here's an example from a popular humor site called Imager.…
Notice the Next Item button is large and colorful…to be easy to find.…The Back button is right next to it…with good proximity indicating the relationship…but it's smaller and less prominent.…But if developers have a bad tendency…to violate Fitt's Law it's nothing to their habit…of violating this design principle.…HIck's Law is common sense.…It says you will have a harder time…finding the option you want if it's in a large group…of options you must scan through.…
That seems obvious,…but I see applications all the time…where there are hundreds and hundreds of menu options…
