Edwards, W. Keith, Newman, Mark W., Sedivy, Jana Z. and Smith, Trevor F. (2009): Experiences with recombinant computing: Exploring ad hoc interoperability in evolving digital networks. In ACM Transactions on Computer-Human Interaction, 16 (1) p. 3.

This article describes an infrastructure that supports the creation of interoperable systems while requiring only limited prior agreements about the specific forms of communication between these systems. Conceptually, our approach uses a set of "meta-interfaces" -- agreements on how to exchange new behaviors necessary to achieve compatibility at runtime, rather than requiring that communication specifics be built in at development time -- to allow devices on the network to interact with one another. While this approach to interoperability can remove many of the system-imposed constraints that prevent fluid, ad hoc use of devices now, it imposes its own limitations on the user experience of systems that use it. Most importantly, since devices may be expected to work with peers about which they have no detailed semantic knowledge, it is impossible to achieve the sort of tight semantic integration that can be obtained using other approaches today, despite the fact that these other approaches limit interoperability. Instead, under our model, users must be tasked with performing the sense-making and semantic arbitration necessary to determine how any set of devices will be used together. This article describes the motivation and details of our infrastructure, its implications on the user experience, and our experience in creating, deploying, and using applications built with it over a period of several years.

Edwards, W. Keith, Newman, Mark W., Sedivy, Jana Z. and Smith, Trevor (2004): Supporting serendipitous integration in mobile computing environments. In International Journal of Human-Computer Studies, 60 (5) pp. 666-700.

In the richly networked world of the near future, mobile computing users will be confronted with an ever-expanding array of devices and services accessible in their environments. In such a world, we cannot expect to have available to us specific applications that allow us to accomplish every conceivable combination of devices that we may wish. Instead, we believe that many of our interactions with the network will be characterized by the use of "general purpose" tools that allow us to discover, use, and integrate multiple devices around us. This paper lays out the case for why we believe that so-called "serendipitous integration" is a necessary fact that we will face in mobile computing, and explores a number of design experiments into supporting end user configuration and control of networked environments through general purpose tools. We present an iterative design approach to creating such tools and their user interfaces, discuss our observations about the challenges of designing for such a world, and then explore a number of tools that take differing design approaches to overcoming these challenges. We conclude with a set of reflections on the user experience issues that we believe are inherent in dealing with ad hoc mobile computing in richly networked environments.

Newman, Mark W., Izadi, Shahram, Edwards, W. Keith, Sedivy, Jana Z. and Smith, Trevor (2002): User interfaces when and where they are needed: an infrastructure for recombinant computing. In: Beaudouin-Lafon, Michel (ed.) Proceedings of the 15th annual ACM symposium on User interface software and technology October 27-30, 2002, Paris, France. pp. 171-180.

Users in ubiquitous computing environments need to be able to make serendipitous use of resources that they did not anticipate and of which they have no prior knowledge. The Speakeasy recombinant computing framework is designed to support such ad hoc use of resources on a network. In addition to other facilities, the framework provides an infrastructure through which device and service user interfaces can be made available to users on multiple platforms. The framework enables UIs to be provided for connections involving multiple entities, allows these UIs to be delivered asynchronously, and allows them to be injected by any party participating in a connection.

Edwards, W. Keith, Newman, Mark W., Sedivy, Jana Z., Smith, Trevor, Balfanz, Dirk, Smetters, D. K., Wong, H. Chi and Izadi, Shahram (2002): Using speakeasy for ad hoc peer-to-peer collaboration. In: Churchill, Elizabeth F., McCarthy, Joe, Neuwirth, Christine and Rodden, Tom (eds.) Proceedings of the 2002 ACM conference on Computer supported cooperative work November 16 - 20, 2002, New Orleans, Louisiana, USA. pp. 256-265.

Peer-to-peer systems appear promising in terms of their ability to support ad hoc, spontaneous collaboration. However, current peer-to-peer systems suffer from several deficiencies that diminish their ability to support this domain, such as inflexibility in terms of discovery protocols, network usage, and data transports. We have developed the Speakeasy framework, which addresses these issues, and supports these types of applications. We show how Speakeasy addresses the shortcomings of current peer-to-peer systems, and describe a demonstration application, called Casca, that supports ad hoc peer-to-peer collaboration by taking advantages of the mechanisms provided by Speakeasy.

Newman, Mark W., Sedivy, Jana Z., Neuwirth, Christine, Edwards, W. Keith, Hong, Jason I., Izadi, Shahram, Marcelo, Karen, Smith, Trevor F., Sedivy, Jana and Newman, Mark (2002): Designing for serendipity: supporting end-user configuration of ubiquitous computing environments. In: Proceedings of DIS02: Designing Interactive Systems: Processes, Practices, Methods, & Techniques 2002. pp. 147-156.

The future world of ubiquitous computing is one in which we will be surrounded by an ever-richer set of networked devices and services. In such a world, we cannot expect to have available to us specific applications that allow us to accomplish every conceivable combination of devices that we might wish. Instead, we believe that many of our interactions will be through highly generic tools that allow enduser discovery, configuration, interconnection, and control of the devices around us. This paper presents a design study of such an environment, intended to support serendipitous, opportunistic use of discovered network resources. We present an examination of a generic browser-style application built on top of an infrastructure developed to support arbitrary recombination of devices and services, as well as a number of challenges we believe to be inherent in such settings.
