The study outlined in this paper assesses an architect’s ability to experience ‘design flow’, during the ideation phase, based on the type of design tool utilized. In order to test the hypothesis, I conducted a workshop with a group of MSc architecture students. The students were asked to engage in two design conditions: where they sketch with analogous tools and where they sketch with digital tools. The comparison of these two conditions was based on an EEG and protocol analysis. The results indicate that the use of analogous sketching tools led to a ‘richer’ and prolonged ‘design flow’ experience
that was non-tool focussed. The study provides insights into why analogous sketching is an essential activity during conceptual ideation and why it should be emphasized as a tool in design education going forward.
