Effective architect-client communication is crucial for the successful progress of the design process. Traditional 2D sketches may pose challenges due to the high uncertainty experienced by clients regarding the project. This kind of communication is perceived as the intersection of clarity of information, clarity of sketched representations, and suitable communication methods (verbal and non-verbal). Aiming to support it, this case study evaluates the level of uncertainty and clarity experienced by architects and clients when using 2D digital sketches and immersive 3D sketches during co-ideation. This case study followed an architect and two clients co-ideating two similar small projects, using three digital sketching tools: 3D sketches on Gravity Sketch using Oculus Quest 2 VR headsets, Hyve-3D co-design immersive projection system (VR without headsets), and 2D sketches with a digital tablet using its pen. Each project included three twenty-minute sessions per tool, followed by a questionnaire. Preliminary findings suggest that 3D sketches offer better clarity and reduce participants' uncertainty. We found generally high expectations from the tools at the beginning of the collaborative sessions and a subsequent decrease in impressions at the end due to the lack of clarity of the proposed representations. The immersive projection system better supported non-verbal communication, observed through gestures, whereas the VR headset restricted this activity.

The paper discusses 23 interviewed architects in practice about the role of traditional and digital sketching (human-computer interaction) in communication with the client. They were selected from I995 to 20I8 (the interval of graduation) from three different countries: The Czech Republic (CR), Slovakia (SR), Netherland (NR). To realize three blending areas that impact the approach to sketching: (I) Traditional hand and physical model studies (I995-2003). (II)Transition form-designing by hand and PC (2004—20I7). (III) Mainly digital and remote forms of designing (20I8-now). Interviews helped transform 3I "parameters of tools use " from the previous theoretical framework narrowed down into six main areas: (I) Implementation; (2)Affordability; (3)Timesaving; (3) Drawing support; (5) Representativeness; (6) Transportability. Paper discusses findings from interviewees: (A) Implementation issues are above time and price. (B) Strongly different understanding of what digital sketching is. From drawing in Google Slides by mouse to sketching in Metaverse. (C) Substantial reduction of traditional sketching (down to a total of 3% of the time) at the expense of growing responsibilities. (D) 80% of respondents do not recommend sketching in front of the client. Also, other interesting findings are further described in the discussion.

The traditional sketch using pencil and paper is an indispensable medium for architects. Digital technology both imitates and extends the possibilities of the sketch into a new form, the Architectural Digital Sketch. In this paper, we present a descriptive framework from the theoretical perspective of technology parameters. This framework covers traditional and digital sketch. We investigated several representative tools for sketching employing the framework, such as traditional sketch, Wacom SmartPen, iPad Pro, Foldable Notebook Lenovo ThinkPad X1 and Hyve3D. We demonstrate how the framework gives a unified approach to such widely varied tools.
