New Challenges in Display-Saturated Environments

Abstract

We live in a world in which our physical spaces are becoming increasingly enriched with computing technology. Pervasive displays have been at the forefront of this progression and are now commonplace. In this paper, we focus on the natural end-point of this trend and consider the case when displays become truly ubiquitous and saturate our physical environments. We use as motivation a stateof-the-art display deployment in which mobile users navigating the space are simultaneously exposed to many hundreds of displays within their field of view and we highlight a number of new research challenges. (iv)Reduced time when viewers do not have a display within their field of view.These trends are leading to the emergence of technology-rich spaces that feature unprecedented numbers of embedded displays, either arranged to form very large video walls or distributed throughout the environment. For example, in spaces that we are currently exploring viewers can see multiple pervasive displays from any single viewpoint in the space. These displays include a large network of smaller displays distributed throughout the space and a single high-definition video wall in excess of over 650 displays. In contrast to typical media facades, viewers constantly experience a high variety of differently-scaled displays as they navigate through the space. We term such environments display-saturated environments and informally define them as environments in which the display density is such that users typically have multiple displays in their field of view at any point in time, i.e. as users navigate the physical space displays are omnipresent -seeing a display becomes the norm not the exception.

A Longitudinal Study of Pervasive Display Personalisation

“…The selection of appropriate content may be based either on explicit user preferences (as in [15,18,43] or determined implicitly based on contextual information about the viewer (or group of viewers) currently present in front of a display [36]. In this paper we focus on explicit user preferences to determine content personalisation.…”
