5 narrated scenes. Press play, listen and read along — the points appear as they are explained. Use ‹ Prev / Next › or the scene bar to jump to any scene.
A technician typing commands, a child tapping a tablet and an ATM user choosing from a menu are all using a user interface. Each design suits a different person.
Narration uses your device’s built-in voice. No sound? Switch to “Captions only” — the captions advance on their own.
Copy these into your notebook in your own words — that is how they stick.
How the user communicates with the computer.
Typed commands; fast for experts, hard for beginners.

Windows, icons, menus, pointer; easy but needs more resources.
Finger gestures; natural, small-screen accuracy issues.
Input and output together: ATM, POS, tablet.
Concept, ergonomic, braille.
User skill, task, device and resources.
