This paper investigates the transfer of tacit knowledge between designers and the computer in architectural design. Most research efforts in computational architectural design recently focus on the tangible and technical domains of the design process. This resulted in a lack of understanding of the role of other qualitative intangible domains, such as tacit design knowledge, in the computational design process. Despite the attempts of a few recent studies to tackle some tacit aspects within design computing, little research extended further to study how tacit knowledge can be transferred between different entities of the computational design process and how it can be represented. Through an analytical review, the paper will first discuss the notions of tacit knowledge in different disciplines, with particular emphases on architecture. Second, the study reviews the conditions and factors that influence the transfer of tacit knowledge between humans, and accordingly between the human and the computer, as addressed by different architects and authors. The study particularly emphasizes the significance of a human- computer symbiotic relationship for the process of tacit knowledge transfer to take place. In conclusion, this paper presents a theoretical basis for understanding and facilitating the transfer and representation of tacit knowledge in a computational design environment. Keywords: tacit knowledge transfer, computational design, designer-computer interaction
