The impact of ubiquitous technology and social media on our lives is rapidly increasing. We explicitly need to consider personal values affected or violated by these systems. Value-sensitive design can guide a designer in building systems that account for human values. However, the framework lacks clear steps to guide elicitation of stakeholders' values. We(More)
Explicitly considering human values in the design process of socio-technical systems has become a responsibility of designers. It is, however, challenging to design for values because (1) relevant values must be identified and communicated between all stakeholders and designers and (2) stakeholders’ values differ and trade-offs must be made. We focus on the(More)
In this paper we advocate the use of personal informatics systems for self-reflection on personal values. We describe the role values play as guiding principles in people's lives. We then describe Value-Sensitive Design, an approach to the design of technology that aims to account for values throughout the design process. We subsequently argue that personal(More)
Personal informatics apps that promote healthy consumption share similar aims, but vary in the means they adopt to meet them. The adopted means reflect different stances. Stances are the positions that designers implicitly take on a range of issues, such as personal information, freedom of choice and responsibility. Judgments on values such as privacy,(More)
As software plays an increasingly important role in people's lives, the impact it has on their values frequently becomes apparent. Many software design methods address " soft issues " , but very few address values explicitly. We present six principles that design methods should meet in order to properly deal with values. One area in which adherence to(More)
This workshop brings together scholars and practitioners of human-centered computing, requirements engineering, ethics and related fields. We will share knowledge and insights on methods to account for human values in information technology design. Through short presentations, group discussions and practical design group work, participants will collaborate(More)
A large amount of research attempts to define trust, yet relatively little research attempts to experimentally verify what makes trust needed in interactions with humans and technology. In this paper we identify the underlying elements of trust-requiring situations: (a) goals that involve dependence on another, (b) a perceived lack of control over the(More)
Software systems can give rise to ethical issues, with human values such as privacy, autonomy and responsibility at their heart. Such issues often do not become apparent until software has been put to use, and are left to be dealt with after harm has been done. However , these ethical issues are influenced by decisions made during design. A range of(More)
