Annotations in design drawings have not seen much research attention, although they do reveal part of the design content. We study the effects of offering feedback to annotations, namely by presenting word graphs that contain the architect's annotations and semantic associations based on these words. The research method entails a working prototype, called the Idea Space System (ISS), in an experimental setting in which 18 architects participated. The findings of the experiment show that architects appreciate the use of word graphs. They experience pleasure, an improvement of the work flow, and especially get more associations. We cannot find a significant increased creativity of the resulting designs, nor a significant reduction of fixation.
