to investigate the role of values in technology acceptance in general and in the context of the UK Covid Track and Trace App. A survey and interview study was conducted to elicit users’ perceptions of values in general, values in relation to choice of IT products and values which were influenced the decision to download (or not) the NHS Covid-19 Track and Trace App. Other non-value issues such as utility, price and recommendations were considered. Users’ value in life differ slightly from those considered important for selecting IT products. For general IT product decisions, functionality, trust and price with values equality, security and sustainability were important. For the Covid-19 App decision two values, helpfulness and equality, with recommendations/trust and operating system compatibility, were the main influences. Interview data indicated that downloader users were motivated by social responsibility and utility – being able to access workplaces and leisure venues – while non-downloaders had little perceived need for the App, combined with mistrust of the App's provenance (NHS and the Government) linked to security and privacy concerns. The implications for values in technology acceptance decisions are discussed.

Many innovative software products are conceived, developed and deployed without any conventional attempt to elicit stakeholder requirements. Rather, they are the result of the vision and intuition of a small number of creative individuals, facilitated by the emergence of a new technology. In this paper we consider how the conditions that enable new products' emergence might be better anticipated, making innovations a little less reliant on individual vision and a little more informed by stakeholder need. This is particularly important where a new technology would have the potential for social impact, good or bad. Speculative design seeks to explore this landscape. We describe a case study using a variant called design fiction to explore how plausible new technologies might impact on dementia care.
