In Rapid Ideation and Creative Problem Solving we use an effective, iterative and user-centered process for wire-framing. Our project for the past 6 weeks has been to wireframe and iterate on our thermostat design for a total of 6 times. Project details for Iteration 5 below:
Function and Features List (should include at minimum)
- Adjust temperature to warmer / cooler
- Switch between heating & cooling
- Turn the system on and off
- Turn the fan on and off
- Set / edit a 7 day schedule
- Interrupt the schedule to adjust the temperature
Once we iterate on our design – we then conduct usability testing using the think-aloud method to understand and solve any usability issues that may come up during testing.
Think Aloud Testing User Comments for Iteration 5
- Where is the schedule?
- How does the home/away feature work?
- Thought the white line was just a printing error
- The cool to heat gradient line is a bit confusing – I don’t know what it means when adjusting temperature
- Where are the numbers letting me know where I am or where I could adjust the temperature to?
- I feel dumb!
So I went back to the white board with Professor Matt Franks to work through some ideas around Schedule and Home/Away features.
Sketches from our white-boarding session
After working through user issues on the white board – I redesigned the wireframes to include the updates below:
- Current temperature number and text changes when user adjusts temperature
- Temperature controller now shows what the current temperature is set to
- The cool to warm gradient has been update
- Home and Away flow update
- On and Off button update
- Wi-Fi flow update
Updated screens below:
Wi-Fi On/Off Flow
In reflection, I didn’t realize just how challenging ‘simple and easy to use’ was to design for. To view a full set of annotated wireframes for Iteration 5 please click here. Previous Iterations and Concept Models for reference below:
