Use of graphical modality in a collaborative design distant setting.

Area of Science:

• Human-Computer Interaction
• Computer-Supported Cooperative Work
• Architectural Design Education

Background:

• Remote collaboration in design fields faces challenges in replicating in-person interaction dynamics.
• Existing tools often lack integrated multimodal communication, limiting synchronous design activities.
• The need for effective digital environments to support distributed design teams is growing.

Purpose of the Study:

• To evaluate the effectiveness of a novel environment, the Distributed Collaborative Design Studio (DCDS), for remote, multimodal collaboration.
• To investigate the role of graphical communication (digital sketching and annotations) in synchronous remote design meetings.
• To understand how DCDS supports different collaborative design strategies in an architectural studio setting.

Main Methods:

• The study involved 3 groups of architecture students from Belgium and France collaborating remotely over 3 months.
• Utilized the DCDS environment, which combines videoconferencing with a real-time shared digital sketching system.
• Analyzed digital annotations and sketching practices during synchronous remote meetings.

Main Results:

• Digital annotations and sketches played a significant role in cognitive design processes and collaboration.
• Different groups exhibited distinct digital sketching practices aligned with their collaborative strategies.
• The DCDS environment facilitated both co-design and distributed design approaches.

Conclusions:

• Graphical modalities, particularly digital sketching and annotations, are valuable supports for synchronous collaborative design activities.
• The DCDS environment effectively supports diverse collaborative design strategies in remote settings.
• Recommendations are provided for improving sketch-based collaborative systems and the DCDS itself.
