Paper prototyping is a technique that allows you to create and test user interfaces quickly and cheaply. It's easier to change a prototype than the final design. 

This 40-minute training video demonstrates how to build paper prototypes and get usability feedback from real users early.

The demonstrations in the video feature web, applications, mobile devices, and hardware user interfaces.

Benefits

• Instant download in MP4 and WMV formats
• Learn a fast and inexpensive technique to get user feedback early in a design project
• Learn to convince skeptical members of your team who do not believe that it is possible to test unpolished designs; showing beats telling.
• Good educational video for Human Factors and INteraction Design students

Topics covered

• Introduction: What is paper prototyping and why you should use it
• Materials: What paper prototypes look like and how they're created
• How to represent widgets and interactions. Get tips on:
  • sketching screens
  • representing user interface widgets
  • simulating complex interactions such as drag & drop, scrolling, and multimedia
• Testing websites with low fidelity prototypes (hand sketches)
• Testing websites with higher fidelity prototypes (computer-created prototypes)
• Testing mobile devices
• Testing hardware and kiosks

Stills from the video

Low-fidelity paper prototypes just require paper and pen to simulate an interface:

High-fidelity paper prototypes are made via desktop publishing programs or design software such as Photoshop or Illustrator:

All manner of interfaces can be simulated using paper. For example, mobile applications:
