Collaborative brainstorming can be a challenging but important part of creative group problem solving. Mind-mapping has the potential to enhance the brainstorming process but has its own challenges when used in a group. We introduce GroupMind, a collaborative mind-mapping tool that addresses these challenges and opens new opportunities for creative teamwork, including brainstorming. We present a semi-controlled evaluation of GroupMind and its impact on teamwork, problem solving and collaboration for brainstorming activities. GroupMind performs better than using a traditional whiteboard in both interaction group and nominal group settings for the task involving memory recall. The hierarchical mind-map structure also imposes important framing effects on group dynamics and idea organization during the brainstorming process. We also present design ideas to assist in the development of future tools to support creative problem solving in groups. Categories and Subject Descriptors H.5.3 [Inf...
