Can we design CAAD to enhance creativity? CAAD is often considered a tool that assists architects in design by managing documentation and facilitating visualization. While there has been anecdotal concern that CAAD inhibits creativity, there is empirical evidence that CAAD can enhance creativity. The challenge is to develop principles for designing CAAD for creativity based on theoretical and empirical research on recognizing and enhancing individual and distributed creative cognition. This presentation describes three concepts that can lead to principles for designing CAAD to enhance human creativity: recognition, perception, and diversity. // 1. Recognition: A framework for recognizing and evaluating creative design, shown in Figure 1, is developed based on research in psychology and design science that includes novelty, value, and surprise. This framework provides a basis for comparing and evaluating the impact of CAAD on creativity. 2. Perception: Perception affects cognition and therefore interaction design is a critical component of designing CAAD for creativity. The results of an empirical study, shown in Figure 2, using a protocol analysis find that changing perception to include tangible user interfaces has a positive effect on creative cognition. These results lead to design principles for increasing perceptual modalities in future CAAD systems. 3. Diversity: A theoretical framework for social and collective intelligence in design show how an increase in cognitive diversity leads to an increase in innovation. Using this framework we can develop design processes that combine the benefits of individual, team, and crowdsourced design ideas, as shown in Figure 3.
