Key Design Principles

These core concepts appear across all eras:

The Big Five (1992 Macintosh HIG)

1. Metaphors from the Real World Use familiar objects to guide users intuitively

2. Direct Manipulation See-and-point rather than remember-and-type

3. See-and-Point (WYSIWYG) What you see is what you get

4. Consistency Uniform appearance and behavior across apps

5. User Control Forgiveness, modelessness, perceived stability

Evolution Across Platforms

Principle	Lisa (1980)	Mac (1987)	NeXT (1993)	Aqua (2001)	iPhone (2008)
Core Metaphor	Office/Documents	Desktop	Workspace	Digital Environment	App Launcher
Input Method	Mouse	Mouse	Mouse	Mouse	Touch
Visual Style	Monochrome	B&W/Color	NeXT Gray	Translucent	Skeuomorphic
Primary Action	Click	Click	Click	Click	Tap
Navigation	Menus	Menus	Menus	Menus	Gestures
