“…Future research on multi-modal interfaces that employ speech could immensely benefit from our user-centered recommendations. We conducted a preliminary testing of our recommendations and note some of the strengths and challenges in the implementation of a prototype (Khan et al ., 2017).…”

“…The study presented in this paper is based on data collected from a gesture and speech elicitation experiment. As described previously in our studies (Khan et al ., 2017; Khan and Tuncer, 2017; Tunçer and Khan, 2018), the experiment was conducted individually with 20 engineers from an EPD background and 20 architects. EPD is a combination of the traditional disciplines of mechanical engineering and electronics and electrical engineering.…”

“…The experiment was conducted to elicit speech and gesture preferences for conceptual CAD modeling from the stated professional groups. In related studies, we presented user preferences of gestures (Khan and Tuncer, n.d., 2017; Tunçer and Khan, 2018) and the implementation of a prototype (Khan et al ., 2017).…”

Speech- and gesture-based interfaces for computer-aided design (CAD) modeling must employ vocabulary suitable for target professional groups. We conducted an experiment with 40 participants from architecture and engineering backgrounds to elicit their speech preferences for four CAD manipulation tasks: Scale, Rotate, Copy, and Move. We compiled speech command terms used by participants and analyzed verbalizations based on three analytic themes: the exactness of descriptions, the granularity of descriptions, and the use of CAD legacy terms. We found that participants from both groups used precise and vague expressions in their verbalizations and used a median of three parameters in their verbalizations. Architects used CAD legacy terms more than Engineers in the tasks Scale and Rotate. Based on these findings, we give recommendations for the design of speech- and gesture-based interface for conceptual CAD modeling.
