A Comparison of Cooperative and Competitive Visualizations for Co-located Collaboration
summary
A repeated-measures study with 12 groups runs four 8‑minute brainstorming sessions each under four conditions: per‑person (competitive), per‑group (cooperative), mixed, and baseline, shown on a balloon wall display. A linear mixed model finds the mixed visualization yields significantly more ideas and a lower Gini balancing index (more equal participation). Questionnaires show competitive feels most motivating, cooperative feels least pressure and most comfortable (26 of 36 participants), while mixed provides the best productivity–comfort tradeoff.
