Study Notes

Prototyping Phases

Prototyping is an essential part of the user-centered design process, involving creating tangible representations of a design to identify challenges, explore subtleties, and gather feedback.
Prototyping phases can be categorized as early design and late design.
Early design focuses on exploring different representations and generating low-fidelity prototypes, while late design involves creating high-fidelity prototypes for usability testing and refining the system through alpha/beta tests.

Low-Fidelity Prototyping

Low-fidelity prototyping emphasizes quick and inexpensive exploration of multiple design alternatives without getting bogged down in technical details.
Users are often more comfortable providing feedback on designs that appear less "finished," encouraging open criticism.
Methods include paper-based sketches, paper prototypes, and physical mock-ups using materials like paper and cardboard.

Sketching

Sketching encourages visualization and communication of design ideas.
It fosters a sense of openness and freedom, abstracting away unnecessary details.
Drawing ability is irrelevant, as sketching is about conveying the concept and exploring different possibilities.

Storyboards

Storyboards use a "comic book" approach to represent a series of keyframes as sketches, illustrating a sequence of interactions.
Originally used in filmmaking to convey scenes, storyboards provide snapshots of the interface at specific points in the interaction.
They help teams quickly evaluate the direction of the interface and can be used with user personas to understand user tasks.

Storyboarding the System

This approach to storyboarding focuses on conveying the context of use, including:
- Setting: People involved, environment, and the task being accomplished.
- Sequence: The steps involved and the events leading to the use of the system.
- Satisfaction: The user's motivation, the end result, and the need being satisfied.
It's effective for communicating the design concept and its context.

Storyboarding the Interaction: Example

This specific example demonstrates a sequence of interface sketches showing how a user might interact with a music player to create a playlist.
The storyboard captures different states of the interface, highlighting user actions and the resulting changes to the interface.
It allows the team to visualize the user's flow and identify potential areas for improvement.
