Communication Economics and Development

Communication Economics and Development aims to determine a methodology for integrating communication variables into economic development models. The first five chapters of the book cover the theoretical issues and their conceptualization as the basis for deriving a better understanding of the role of communication in economic development. The major issues for concern are the economic variables that are endogenous to communication planning in the light of rapid advances in communication technologies. Chapters 6-9 deals with the consideration of the role of communication in national development; the international trade theory and communications; and the political economy of information in a changing international economic order. The Japanese experience in focusing on the role of communication in economic development; a model for predicting development benefits from telecommunication investment; and the role of telecommunications in developing countries are also discussed. The text further describes the impact of telecommunication and information in development planning strategy; the opportunity costs in computer conferencing during and for economic development; and the evaluation of the impact of communication on agricultural development in Nepal. The use of economic concepts in communication planning practice is also discussed.

Proxemic Interactions

In the everyday world, much of what we do as social beings is dictated by how we perceive and manage our interpersonal space. This is called proxemics. At its simplest, people naturally correlate physical distance to social distance. We believe that people’s expectations of proxemics can be exploited in interaction design to mediate their interactions with devices (phones, tablets, computers, appliances, large displays) contained within a small ubiquitous computing ecology. Just as people expect increasing engagement and intimacy as they approach others, so should they naturally expect increasing connectivity and interaction possibilities as they bring themselves and their devices in close proximity to one another. This is called Proxemic Interactions. This book concerns the design of proxemic interactions within such future proxemic-aware ecologies. It imagines a world of devices that have fine-grained knowledge of nearby people and other devices—how they move into range, their precise distance, their identity, and even their orientation—and how such knowledge can be exploited to design interaction techniques. The first part of this book concerns theory. After introducing proxemics, we operationalize proxemics for ubicomp interaction via the Proxemic Interactions framework that designers can use to mediate people’s interactions with digital devices. The framework, in part, identifies five key dimensions of proxemic measures (distance, orientation, movement, identity, and location) to consider when designing proxemic-aware ubicomp systems. The second part of this book applies this theory to practice via three case studies of proxemic-aware systems that react continuously to people’s and devices’ proxemic relationships. The case studies explore the application of proxemics in small-space ubicomp ecologies by considering first person-to-device, then device-to-device, and finally person-to-person and device-to-device proxemic relationships. We also offer a critical perspective on proxemic interactions in the form of “dark patterns,” where knowledge of proxemics may (and likely will) be easily exploited to the detriment of the user.
