The externalization of design ideas is a key activity in design, regardless of any specific design domain. Recent advances in immersive technologies enable us to externalize our ideas in full scale, thereby supporting our ability to generate and test designs on-the-fly. Needless to say, architectural designers can greatly benefit from such technological advances.

In this project, a system for sketching in Mixed Reality (MR) was developed and implemented using a state-of-the-art head mounted display (Microsoft HoloLens 2). The system enables architectural designers to "sketch" their ideas in 3D form with little effort and view them on-site. This augments our ability to create and select design solutions with greater confidence in their viability.

A proof-of-concept was presented at the CAADRIA 2024 international conference (Computer-Aided Architectural Design Research in Asia, Singapore), as a part of a workshop focusing on the future of collaboration in design.
