summary In the realm of computer support for design, developers have focused primarily on power and expressiveness that are important in framing a design solution. They assume that design is a series of calculated steps that lead to a clearly specified goal. The problem with this focus is that the resulting tools hinder the very process that is critical in early phases of a design task; the reflection-in-action process [15]. In the early phases, what is required as the most important ingredient for a design tool is the ability to interact in ways that require as little commitment as possible. This aspect is most evident in domains where two dimensions play a role, such as sketching in architecture. Surprisingly, it is equally true in linear domains such as writing. In this paper, we present our approach of using two-dimensional positioning of objects as a means for reflection in the early phases of a design task. Taking writing as an example, the ART (Amplifying Representational Talkback) system uses two dimensional positioning to support the early stages of the writing task. An eye-tracking user study illustrates important issues in the domain of computer support for design.
