The Ex Situ group is exploring the design of novel interactive systems, with a particular focus on creative professionals, e.g. designers. We have developed a theoretical foundation that enables us to reinvent design technology that retains simplicity while adding power, to empower the user. We build on three conceptual foundations developed in the group:
- Instrumental interaction separates the tools used to manipulate objects from the objects themselves. Using the principles of reification, polymorphism and reuse, we can transform actions into instruments, with which users can compose in their own way, within a distributed, collaborative, and/or multi-surface environment.
- Information substrates are software artifacts that embody content, computation and interaction, effectively blurring the distinction between documents and applications. Substrates create a malleable medium that can be manipulated in a variety of ways, naturally supporting instrumental interaction and co-adaptation.
- Co-adaptation is the process by which users adapt to the tools they use as well as adapt the tools to their needs. Systems that support co-adaptation are discoverable, appropriable and expressive.
The goal of the thesis is to design and develop interactive tools to support designs, based on a combination of empirical studies with users and the application of co-adaptive instruments and substrates as a theoretical foundation.
This Ph.D. involves three main types of research activity:
• empirical studies of creative professionals, including graphic and other designers. Research methodolgy includes structured observation, critical object interviews and participatory design.
• technical development of novel interactive system(s) that are prototyped, implemented and tested with designers; and
• theoretical exploration and testing of the principles of co-adaptive instruments and substrates, with a special emphasis on the process of appropriation.
The thesis will result in novel interactive tools and techniques that help users express and explore complex creative concepts in a a design field, such as graphic design. The thesis will also test the potential and the limits of co-adaptive instruments and substrates.
