Sketching by Cross-Surface Collaboration

Human-Computer Interaction and agile practices in software engineering are not two separate domains, but rather agile is a work principle that is applied in software development, of which user interface design represents a significant part. Agile projects could require such an approach, which typically iterates on the user interface using low-fidelity prototypes. This paper motivates, presents, and assess capabilities of software for collaborative sketching of user interfaces on multiple surfaces of interaction, ranging from mobile phones to wall screens. We propose a Collaborative User Centered Design (CUCD) method for user interface prototyping to supporting cross-surface collaboration by sketching, enabling fast, flexible, intuitive and reusable prototype
