Learning Goals
By the end of this section you will:
understand the purpose of sketches, wireframes and mock-ups in designing UIs
understand the elements that make up mock-ups
understand how annotated mock-ups are used to demonstrate useability and visual communication incorporation in design decisions
In UI Design it is most important to demonstrate how the user will interact with your application. Sketches, wireframes, and mock-ups are used at different stages of development to plan and visualise the interface.
Sketches
Quick, freehand drawings
Used early to explore ideas
Focus on layout and basic function
Not detailed or to scale
Wireframes
Structured, simplified layouts
Show placement of UI elements (buttons, menus, images)
Often in black and white or grayscale
Help define content hierarchy and functionality
Mock-ups
High-fidelity visual designs
Include colours, fonts, spacing and branding
Look like the final product but arenβt interactive
Used for client presentation or UI testing
Key features of mock-ups:
Visual accuracy:
Display exact colours, fonts, spacing, icons, images, and branding
Represent the final visual style of the UI
Not interactive:
Unlike prototypes, mock-ups do not include clickable elements or animations
They show appearance, not behaviour
Used for feedback:
Help clients, stakeholders, and users understand what the final product will look like
Allow for early visual testing and feedback before development begins
Created with design tools:
Common tools include Figma, Adobe XD, Sketch, or Canva
Purpose in UI design:
Communicate detailed visual design choices
Support decision-making about colours, typography, and layout
Identify visual issues before coding
Bridge the gap between wireframes and prototypes
For Digital Solutions:
an essential way of demonstrating how the success criteria have informed your design decisions.
demonstrate your understanding of useability principles and visual communication
