W8 L1 - HCD and Prototyping

HCD vs UCD

Human-Centered design focuses on impact on stakeholders too. User-Centered design focuses on just the users.

4 Stage Model of UCD

Research - Understand users’ needs

Requirements - What problems and pain points will be solved for the users?

Design - Create solutiopns based on requirements

Evaluation - Test designed solutions with real users

Scenarios

Put personas (architypes of target users) into motion, with an example of how they might use the system

Storyboarding

• Walk through of scenario

• Representation is pictorial

• Prototype features not finalised

Sketching

Focuses on design of interface

• Low effort, fast to produce

• Help with ideation

Prototyping

Primitive form of implementation

Soft vs Hard Prototyping

Soft:

• Underlying hardware already exists

• Best suited for apps, websites, etc

Stages of Soft:

• Story boarding, sketching, paper prototypes, static/dynamic UI

Hard:

• Similar to product design

• Underlying hardware doesn’t exist

• Hardware prototype is required to validate/prove theory

Required When:

• Designing a new piece of hardware

• Alternative need when a theory/concept needs to be validated

Paper Prototypes

• Requirements gathered from storyboard are utilised

• First impression of GUI

• Contains familiar OS elements

• But made all with paper

Can do things like simulating phone scroll, application flow, and controls with paper.
