This project explores how social computing system can enable groups of people to collaborative plan for future events. The goal is to combine preferences and constraints from all stakeholders so that people feel engaged and have a better overall experience. As a concrete example, this project has create a series of software interfaces called Cobi, which seeks to engage an entire academic community in planning a large-scale conference. Cobi elicits community members’ preferences and constraints, and provides a scheduling tool empowering organizers to take informed actions toward improving the schedule. The project ended, but if you are interested in talking about the ideas, please reach out to Steven Dow.
