be jointly designed to create a rich environment that suits the complexities and variety of life in the home. In so doing, we hope to articulate new design opportunities, as well as to encourage critical reflection on existing trends and assumptions.

To demonstrate that this heterogeneous home framework

offers a fertile design space for a wide variety of new objects and environments, we created a design sketchbook. In spirit, our efforts are similar to work such as Gaver and Martin’s workbook of inspirational design proposals to explore the design space of information appliances [ 11]. The sketches we developed are

not necessarily literal design proposals, but rather are intended to engage the reader with ideas ranging from highly speculative concepts to humorous suggestions to very simple product ideas.

To generate the design sketches, we engaged in a collaborative dialogue with each
