Constraint-based Design Critic for Flat-pack Furniture Design
    This paper reports on the Flat-pack Furniture Design Critic (FFDC). By analyzing the literature of architecture education, we have identified critiquing methods: delivery types (interpretation, introduction, example, demonstration, and evaluation) and communication modalities (written comments, graphical annotations, and images). Our FFDC uses these methods to deliver feedback. This paper also presents how our FFDC system selects particular methods by considering a certain condition such as user�s knowledge level and the previously used methods.
