As of July 2011, our 4-person team is working on a project in partnership with Eaton to develop mobile applications for monitoring real-time energy use for energy conservation. The MHCI Capstone course is an 8-month long project for a real-world client to conduct in-depth user research and develop and test functional prototypes. In the Spring of 2011, we conducted over 30 user interviews in Pittsburgh, San Francisco, and New York City, and worked with residents in both apartments and homes, retail and commercial business managers, and commercial facilities managers. We also analyzed over 40 years of research about energy consumption behavior along with recent research about technological intervention in in-home energy monitoring. From our research, we published a 120-page report detailing our findings and providing key actionable insights to aid in the design and development of products in the mobile energy monitoring space. In the Summer term, we set out to iteratively develop and test prototypes for mobile devices, with a final report, complete UI spec, and functional prototype to be delivered by August.
