We present a body of work undertaken in response to the challenge outlined by Harper et al. in their paper, ?'What is a File?' [9]. Through a conceptual and design-led exploration of new file metaphors, we developed the 'file biography', a digital entity that encompasses the provenance of a file and allows the user to keep track of how it propagates. We explored this through prototyping and utilised it in two user studies. In the studies, we (i) asked people to sketch out file biographies for their own content, and (ii) deployed a tool enabling users to build their own simple file biographies across multiple versions of Word documents. We conclude that new file metaphors may need to play different roles for different types of digital content, with a distinction being drawn between content that is 'in production' and virtual possessions that are, in a sense, a 'finished' artefact.

The regulatory climate is in a process of change. Design, having been implicated for some time, is now explicitly linked to law. This paper recognises the heightened role of designers in the regulation of ambient interactive technologies. Taking account of incumbent legal requirements is difficult. Legal rules are convoluted, uncertain, and not geared towards operationalisable heuristics or development guidelines for system designers. Privacy and data protection are a particular moral, social and legal concern for technologies. This paper seeks to understand how to make emerging European data protection regulation more accessible to our community. Our approach develops and tests a series of data protection ideation cards with teams of designers. We find that, whilst wishing to protect users, regulation is viewed as a compliance issue. Subsequently we argue for the use of instruments, such as our cards, as a means to engage designers in leading a human-centered approach to regulation.

We explore the ethical implications of HCI's turn to the ‘cultural’. This is motivated by an awareness of how cultural applications, in our case interactive performances, raise ethical issues that may challenge established research ethics processes. We review research ethics, HCI's engagement with ethics and the ethics of theatrical performance. Following an approach grounded in Responsible Research Innovation, we present the findings from a workshop in which artists, curators, commissioners, and researchers explored ethical challenges revealed by four case studies. We identify six ethical challenges for HCI's engagement with cultural applications: transgression, boundaries, consent, withdrawal, data, and integrity. We discuss two broader implications of these: managing tensions between multiple overlapping ethical frames; and the importance of managing ethical challenges during and after an experience as well as beforehand. Finally, we discuss how our findings extend previous discussions of Value Sensitive Design in HCI.

A study of an interactive artwork shows how artists engaged the public with scientific climate change data. The artwork visualised live environmental data collected from remote trees, alongside both historical and forecast global CO2 data. Visitors also took part in a mobile sensing experience in a nearby forest. Our study draws on the perspectives of the artists, visitors and a climate scientist to reveal how the work was designed and experienced. We show that the artists adopted a distinct approach that fostered an emotional engagement with data rather than an informative or persuasive one. We chart the performative strategies they used to achieve this including sensory engagement with data, a temporal structure that balanced liveness with slowness, and the juxtaposition of different treatments of the data to enable interpretation and dialogue.

Ideation Decks is a project that explores the development of a methodological tool for design ideation It involves the creation and use of bespoke project-specific card based systems which help to define constrained design problems within a broader overall problem space. Use of this system is intended to support the practice of parallel design by design practitioners, and to help more effectively explore specific problems by aiding in iterative design explorations.
