The PhotoSlap game: play to annotate
Tsung-Hsiang Chang, Chien-Ju Ho, Jane Yung-jen Hsu · 2007
This paper presents PhotoSlap, an intelligent system for semantic annotation of photos. The system con-tains a semi-automatic face detector, a bulk annotation tool, and a multi-player online game, PhotoSlap. By exploring the design principles of gameplay and apply-ing game theoretic analysis, PhotoSlap is designed as a fun and productive game, which adapts itself to differ-ent players to produce the desired output. Experiments involving four focus groups showed the game to be fun and effective in annotating people metadata for personal photo collections.
