In this semester-long assignment, each 5 member team was asked to design a collaborative shopping system based on an existing contextual inquiry video. Emphasis was given more on the methods and processes that the team followed. We employed a number of techniques like modeling, heuristic analysis, keystroke level modeling, cognitive walk-through, think aloud usability study and, experience prototyping. The team at one point had difficulty coming to a conclusion due to the lack of data from the CI video, which drove us to a super market in downtown for a body storming session, to find an answer.

The end product was a browser plug-in and an interactive interface that can be used in multiple platforms like iPhone, web, Microsoft surface etc. during the exploration phase, the team identified key issues such as difficulty in taking the final decision, loosing interest due to lengthy buying procedure and many more. We addressed the problem by designing an engaging game like experience that will make group shopping a truly fun activity.

Most of our design ideas were inspired from the data collected during the contextual inquiry. The influences highlighted by the cultural model identified group harmony as a key factor for consideration in the group shopping experience.
