Study Notes

Prototyping Overview

Prototyping is essential for gathering user feedback on designs, typically incorporating mockups of dialogue boxes.
Local prototypes are short-lived, focusing on specific design issues and can evolve into various prototype types as needed.

Fidelity of Prototypes

The fidelity level indicates how complete a prototype appears to users, rather than its technical accuracy.
Prototypes can be categorized into low, medium, and high fidelity, each serving distinct purposes in the design process.

Low-Fidelity Prototypes

Not precise representations, low-fidelity prototypes convey abstract impressions of the design.
These prototypes are used early in the design phase when details are undecided to avoid unnecessary effort.
Paper prototypes exemplify low fidelity, offering significant user experience value relative to input costs.
Despite their simplicity, low-fidelity prototypes can be surprisingly effective and are a valuable design tool.

Medium-Fidelity Prototypes

Medium fidelity bridges the gap between low and high fidelity, often used when more detailed representations are needed.
Wireframes are a common medium-fidelity method, showcasing layouts and user interface components effectively.
These prototypes are useful in intermediate and detailed design stages.

High-Fidelity Prototypes

High-fidelity prototypes provide greater detail, mirroring the final product's appearance, behavior, and functionality.
Essential for evaluating design details, high-fidelity prototypes facilitate refinement before implementation.

Comparison of Prototype Types

Low-Fidelity Prototypes:
- Strength: High flexibility and low cost of fixes; ideal for early design phases.
High-Fidelity Prototypes:
- Strength: Realistic appearance comes at higher costs for changes; suited for later stages.

Coding Implications

Programming teams may wish to start coding too early; this can hinder design flexibility and lead to resistance against changes.
It's crucial to manage timing and avoid premature coding to keep the design adaptable until it's appropriately established.

Paper Prototypes in Design Reviews

Early paper prototypes lack functionality but can effectively showcase the appearance and basic sequencing of interfaces.
Useful for initial design reviews, they help visualize the intended user interaction without providing interactive functionality.
