7. Concept Development In this stage of the design process, we discussed several design concepts and ideas, identified target users, listed tasks and use scenarios. We have also interviewed some Facebook users to understand their lifestyle and listen to their concerns about the design concept.
10. Paper Prototype The paper prototype was made of paper and post-it notes. The interface was drawn by hand. Some essential colors were applied using color pencils, which provide the user a general look and feel to the interface.
11. Usability Test The usability test involved 5 participants who were guided through several tasks using the paper prototype, such as navigating through the power consumption charts and building their GreeNet garden . Along with these tasks, we asked the participants to complete a survey and summarized the funding into usability categories.
13. Design Iteration & High-fidelity Prototype By gaining feedback from the users, we have created a high-fidelity prototype using Adobe Illustrator and Macromedia Flash.
37. Future work Our future work will involve further usability testing with our current, flash-based, prototype. The results of the tests will inform the next stage of the design process, where we will develop a functional user-interface for our application created using Silverlight, Expression Studio.
38. Conclusion Through our user-focused design process, we have created GreeNet to be not only an informative interactive system, but also an interface that engages our audience into participating in a culture of energy conservation.
