Speck: HOMe Air Quality Monitor
Team: Stella Zubeck, Alanna Fusaro, Christiana Lackner
Role: Interface/Interaction Design, User Research
UNDERSTANDING YOUR AIR QUALITY
Speck is a device that allows the average person to understand and observe trends in their indoor air quality. The device was developed at Carnegie Mellon University's Robotics Institute. I worked with a team of interaction and industrial designers to redesign the user interface for Speck.
THE OLD INTERFACE & FORM FACTOR
Speck measures the density of particulate matter, specifically PM 2.5. The old interface for the device displayed the last hour of air quality in a graph. The only interaction the device's UI allowed for was adjustment of the screen's back light by touching the corner of the screen.
Speck device's old UI suffered from three key issues (unearthed during user testing):
Readings were difficult to understand
Capabilities weren't fully understood
Consumer-friendliness limited by a lack of visual appeal
With those pain points in mind, we began brainstorming different UI concepts for Speck. We were also curious about how much information people needed to find the Speck device useful.
I created mock-ups of different interface concepts for Speck to test with users.
TESTING REDESIGN CONCEPTS
ITERATION & IDEATION
Based on feedback from our initial testing sessions, we revised our designs and began wireframing a final iteration.
Possible home screens. Opted for 3rd based on positive user/client feedback.
Home screen + Graph Views (12 hours & last hour)
Demonstrates interaction that enables user to navigate from one screen to another.
Stella and I created the final specs for the interface
THE NEW UI
Speck, with the redesigned UI. I used a dusty old jacket of mine to test the device...I threw the jacket away after seeing the results.
