Abstract: We present an approach to the design of mixed reality spaces that aims to create a more harmonized and unified user experience. We refer to these as blended spaces. Blended spaces draw upon a description of physical and digital spaces in terms of the ontology, topology, volatility and agency. By describing physical and digital spaces in these terms we are able to use the process and design principles of conceptual blending to arrive at a design that maximizes the relationships between the spaces. It also guides the development of the touch points between the physical and digital spaces. We discuss the user experience in blended spaces and briefly allude to the significant philosophical implications that blended spaces of the future will have to deal with.

An interesting analysis of the relationship between the real and virtual in mixed reality. Though I would like to see more discussion of how the examples relate to the theory
Posted by Marco Gillies | July 26, 2012, 10:31 amI really liked the introduction and defining what is blended spaces. I would like to see more results about user behaviors. What distinguish this work from the state of the art?
Posted by Sam Zargham | July 30, 2012, 11:55 amI think this is a very interesting case of design in a very particular context. I might suggest using it as a case study to elaborate how we might explore this particular design space. That is, in addition to the examples presented in the paper (which I find creative and compelling), maybe clarify by listing all the multiple competing goals that are being aimed at, and how each of these examples have various pros and cons. Then maybe for each idea explore the design space very close to it – how that design might be slightly tweaked and how that would change various pros and cons.
