Rapid Prototyping
Blue
Blue was a project I worked on with a team of developers at Cornell. This project was in response to a competition for a human computer interaction problem. Our team chose to confront issues in the environmentalism category and prototype an app that created a simple and pleasing way to conserve water and energy.
Explored the problem space, personas, field studies——Concept Brainstorm
Storyboarding and testing each other on work flow, paper prototype
First mockups
Used Balsamiq to create first prototypes to be tested on
Developed data collection techniques, Context interview plan,
Used Invision to make wire-frames then interactive prototypes
Created different screen states, visualizing the interactions with hotspots
Conducted Heuristic evaluations with team members
Heuristic evaluation with video run through found here
Conducted Heuristic evaluations with human subjects

User testing was conducted using interview questions we wrote about the usability of the application. The qualitative data collected informed our next iteration on the prototype. We made sure to include not just what the user said during the testing but how he said it, physical behaviors etc.
