Situating Media Infrastructure: Understanding the Role of Public Space Characters in Influencing Public Interaction with Media Infrastructure

First and second supervisors

Abstract

The fall in cost of display technology and ubiquity of network technology has driven the expansion of media infrastructure, especially screen networks in the city. Due to the complex nature of outdoor environments, communication between pedestrians and screen content is significantly affected by its situated location. With this concern, the spatial distribution of digital screens and their display content has been posited as an important aspect to consider in the real-world planning and implementation. To select a more supportive environment to deploy screens, it is necessary to identify the characteristics of public spaces that facilitate interactions, and consider them in the future media infrastructure siting.

This research seeks to define the affordance of public space characters in accommodating public interaction with media infrastructure, through the cooperation between urban design and HCI insights. Initially, the review of existing literature helps to identify the characteristics with high odds to support interactions for evaluation. The research will dissect public space characters inclusively from three dimensions: physical, spatial and human activities. Then, it involves a comparative case study of two emergent screen networks that serve a public purpose - InLinkUK network in London and Glasgow. The case study aims to deliver an exhaustive evaluation on how these characteristics influence the interactions with kiosk screens. Followed by analysis of existing documents and related regulations, the research maps out the key decision makers and their criteria for kiosk placement. By comparing the current siting criteria with characteristics defined to support interaction from the case study, the research outcome would inform what location settings should be considered in the future planning of media infrastructure.
