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.

In "Sketching User Experiences: The Workbook," you will learn, through step-by-step instructions and exercises, various sketching methods that will let you express your design ideas about user experiences across time. Collectively, these methods will be your sketching repertoire: a toolkit where you can choose the method most appropriate for developing your ideas, which will help you cultivate a culture of experience-based design and critique in your workplace.
Features standalone modules detailing methods and exercises for practitioners who want to learn and develop their sketching skills

Extremely practical, with illustrated examples detailing all steps on how to do a method

Excellent for individual learning, for classrooms, and for a team that wants to develop a culture of design practice

Perfect complement to Buxton s Sketching User Experience or any UX text Author-maintained companion website at
