Project details
greenBean is a mobile application that lets shoppers discover important information about what they are actually buying. By creating a uniform and easy to understand scoring system for grocery store items, greenBean guides shoppers into making smarter and greener purchases.
This group project was part of CSE:441, a course on advanced HCI prototyping and evaluation methods. We took a project that was already designed to a medium-fidelity prototype in flash in a HCI foundation course. For this project we followed an iterative design process. In each iteration we tried several evaluation techniques: heuristic evaluations, online usability testing and pilot lab studies and improved the design at each stage.
My biggest learning in this project was in: (i) having a hands on experience with several usability techniques, (ii)incrementally improving design at various level of detail and (iii) in working with developers to ensure the usability findings translate into real product improvement.
