Impromptu Prototyping and Artefacting: Representing Design Ideas through Things at Hand, Actions, and Talk

Speech analysis for conceptual CAD modeling using multi-modal interfaces: An investigation into Architects’ and Engineers’ speech preferences

“…This is also attributable to the basic nature and low semantic level of the referent manipulation tasks shown to the participants, and we deduce that the difference in scores for the two professional groups would be significant for more complex referents such as buildings. This finding is also aligned with the results from Logan and Radcliffe (2004) who concluded from their study that designers speak with a simple vocabulary in their speech and employed a visual channel to aid in the verbalizations.…”

“…A similar approach to analyze the level of detail is found in the study by Logan and Radcliffe (2004), who analyze details in designers’ verbalizations by counting the number of nouns, verb, and adverbs. Such an approach is seen to be appropriate as a simple test of a verbalization's descriptive specificity (Logan and Radcliffe, 2004). We acknowledge that more complex measures can be developed, for instance, by adding weights to the counts of expressions, based on a given rationale.…”

“…Studies have analyzed designers’ speech in experiments to recognize patterns, qualities, and quantities of speech (Purcell, 1996). Previous studies have also categorized designers’ verbalizations in relationship to gesturing (Logan and Radcliffe, 2004).…”

“…Previous studies have reported that uncertainty is interwoven in design conversations (Luck, 2013). For instance, designers commonly employ vague expressions such as “ here ”, “ this ”, and “ there ” when speaking, often relying on gestures (Harrison and Minneman, 1996; Logan and Radcliffe, 2004). Such vague expressions are generally employed when the speaker does not have precise knowledge.…”

A Study on Situated Cognition: Product Dissection’s Effect on Redesign Activities

“…Prior research suggests that objects, like the ones involved in product dissection, are integral parts of design communication and summer 2013 advances in engineering education a study on situated cognition: Product dissection's effect on redesign activities alter the dynamics in a multi-designer setting [20]. Furthermore, 83% of design actions involve material artifacts [21], and material representations are often used as starting points of design proposals [22]. While research clearly suggests that objects and material representations play a significant role in product design activities, it is necessary to determine if the exposure to material artifacts through product dissection improves students' understanding of product function.…”
