A microwave redesign human computer interaction project
From research to a better microwave.
A simple process kept the project focused.
Understanding the Project.
Start with the problem, people and existing behaviour.
THE BRIEF
Make microwave controls clearer, simpler and easier for everyone to use.

SECONDARY RESEARCH
PRIMARY RESEARCH
Research before redesign.
The main patterns were simple and consistent.
Turn research into a user.
Personas make the problem easier to design for.
What users say, think, feel and do.
Helped connect research findings to real emotions and behaviours.
Find the gap in today's routine.
The problem happens when parents need a quick answer but don't have one.
Decide
User decides to reheat or cook food.
Figure out settings
Looks for the right button or time.
Uncertainty
Confused by multiple options and labels.
Seek help
Sometimes asks someone for guidance.
Use with caution
Uses basic functions and avoids exploring.
Explore before choosing.
Different interface formats were considered based on user needs and context of use.
Design a simple cooking experience.
A smooth and intuitive flow from selecting to cooking.
Choose Function
Select reheat, defrost or cook.
Select food
Pick a preset or set time manually.
Check settings
Review time, power and quantity.
Start cooking
Press start and let it cook.
Get notified
Clear audio/visual alert when done.
To perform any task.
The main flow stays short so parents can finish it without unnecessary steps.
Organise around real tasks.
Four main areas keep the app easy to navigate.
Ideating through storyboarding
Visualising how a user completes a key task on the microwave.
Big Picture Storytelling
Close Picture Storyboarding
Make the interface feel calm.
Visual choices support the same goal: less confusion and easier use.
Physical Wireframes.
These screens represent the core functions for a simple and intuitive experience
Prototypes.
These models show how the physical interface and screen work together.
Test, listen, improve.
We tested the interface with different users.
Can users complete a basic task?
Are the labels and icons clear?
Do the controls and screen make sense?
Where do users get confused?
Use simpler, more familiar words and icons.
Increase spacing and group related functions.
Digital Wireframes.
These screens represent the core functions described in the project
Turn the structure into screens.
These screens show the designed interface with visual style, icons and content.
Heat option with reheat, defrost, melt, boil process options.
Custom option with grill, combination and convection options.
Bake button with different food menu options to bake.
Settings with brightness, language, child lock and volume control options.
Physcial Model
A working model to test the size, placement and interaction of the interface.
Digital Renders
These renders show the final design with a clean and modern look.
Design changes after testing.
Testing is only useful when feedback changes the design.
Busy visuals and unclear labels made it hard to use.
Simpler layout, clear icons and better hierarchy.
Less guesswork. More confidence.
The redesigned microwave makes everyday cooking simpler and more approachable. By combining a clean physical interface with clear on-screen guidance, it helps users cook, reheat and explore with confidence.
