Coupling

My PhD explored the combination (or coupling) of mobile and situated devices, e.g. mobile phones with public digital screens, to determine useful combinations and the issues that arise during the implementation and use of such couples. The following abstract is taken from my thesis, A Framework to Guide the Design of Environments Coupling Mobile and Situated Technologies:

An increasing number of devices are being situated in public spaces yet interactions with such devices are problematic: they tend to be impersonal and subject to social apprehension while devices suitable for specific tasks may be difficult to locate. This thesis considers how one might design for these environments to overcome these issues and deliver engaging user experiences. It proposes the coupling of the interactive features of mobile and situated devices to facilitate personalised interactions with those situated devices. The thesis explores coupling techniques that extend the computational capabilities of the situated device through the addition of the input, output and storage capabilities of the mobile device. Finally it considers how multiple points of coupling can be used to link sequences of interactions with different situated devices providing rich, cohesive experiences across an environment.

The thesis presents a novel framework that builds upon previous work. Existing work is reviewed that links mobiles with single situated displays, and mobiles for mediating the exploration of physical spaces to address the lack of work addressing multiple situated devices in public. This review grounds a proposal and elaboration of a core model of interaction within a coupling environment, providing the basis for a design framework. This was supported by the implementation of a test-bed that consisted of six couples in various configurations, underpinned by a software infrastructure.

Formative user studies refined the framework and revealed novel aspects of the user experience for study. It was found that through support for narrative and personal orchestration, coupling environments afford personalised trajectories. By designing for personal trajectories the visitor has a more enjoyable personal experience and seeks to improve the experiences of others. In addition, coupling environments support social experiences; the step-by-step nature of a visitor’s trajectory through the coupling environment lends itself to gradually introducing visitors to social coupled interaction and reducing social awkwardness.
