The increasing presence of Artificial Intelligence (AI) systems geared towards children necessitates those who design and develop these technologies to understand how to address the emerging ethical questions in their development and use while maintaining a playful, child-friendly approach.Even more importantly, it is crucial to understand how we can address various tensions that have emerged among ethical principles.In this half-day workshop, keynote talks, poster presentations and interactive, "playful by design" will promote hands-on and rights-based design experiences for researchers and practitioners to ideate the benefits and challenges of designing playful and ethical child-AI systems.

Despite efforts to promote children’s rights in digital environments, a gap remains between principles and practice. To understand this gap and identify possible solutions, we examine whether and how designers embed children’s rights when developing digital products and services. Using the child-rights-informed ‘Playful by Design’ (PbD) principles and associated card pack as discussion probes in workshops with 30 designers from diverse companies, we identify designers’ understanding of children’s rights, their workplace requirements for implementing these, and competing professional and commercial priorities faced in designing for children’s play. Findings reveal the challenges of embedding rights-based principles, themselves building on theories of child development, in product design. Designers may believe that children’s rights are sufficiently realised by protecting children from risk, without ensuring their rights to provision and participation. Further, given the competing demands of commercial design settings, designers require a compelling rationale for and a practical means of implementing children’s rights.

Information technology is increasingly designed to increase information transparency as a way to increase trust. However, it can be hard to comprehend and anticipate the social implications of information visibility, people’s competing expectations of transparency versus privacy, and the role of enabling technologies. We devised Live Action Role Play (LARP) as a means for people to explore the potential and consequences of transparency, within a social context of daily transactions related to food, fashion, and finance. Through the process of deliberation, we enabled participants to critically assess their co-created LARP experience and articulate their transparency expectations for design considerations. We report on insights into their expectations and perceived limitations of information technology in delivering transparency, including social measures required to realise the full potential of technology, as well as transparency, while minimising unintended consequences.

People’s data practices and their supporting personal informatics are imbued with a wide range of concepts of value that are central to their data imaginaries. They inform how individuals adopt particular products and services. This elusiveness of value creates a challenge for designers to gauge users’ value preferences, which are personal, contextual and abstract. We propose deliberation as a process to operationalise design for elicitation, reflection and value formation, using Live Action Role Play (LARP). The paper demonstrates how our deliberative LARP precipitates the otherwise ethereal data values to unfold in a social setting. We argue that engaging people in reflecting on and playing out their own value formation offers designers more powerful insights to address complex challenges of data-driven societies. We report on our findings that agency and negotiability are key to transcend the politics of preferences in data practices and thus enhance acceptability.

Distributed ledger technologies (DLTs) have been celebrated for promoting transparency, trust, and efficiency in several domains. However, recent research has also pointed out the potential of these technologies to increase power asymmetries and deepen social inequality. In this paper, we contribute to this discussion by reporting on a collective effort of academics, development partners, local authorities, businesses, and farming groups to look at the potential of DLTs, particularly Blockchains, to support socio-economic development in rural communities in the Caribbean. We present a series of design concepts resulting from this effort and reflect on a method to facilitate stakeholders' experience of possible implementations and enable them to voice concerns, preferences, and expectations. Results from workshops with different groups of stakeholders contribute insights into opportunities and limitations of these applications to enable social development and to level the playing field in agricultural exchanges in developing countries.

Technologies such as blockchains, smart contracts and programmable batteries facilitate emerging models of energy distribution, trade and consumption, and generate a considerable number of opportunities for energy markets. However, these developments complicate relationships between stakeholders, disrupting traditional notions of value, control and ownership. Discussing these issues with the public is particularly challenging as energy consumption habits often obscure the competing values and interests that shape stakeholders' relationships. To make such difficult discussions more approachable and examine the missing relational aspect of autonomous energy systems, we combined the design of speculative hairdryers with performance and deliberation. This integrated method of inquiry makes visible the competing values and interests, eliciting people's wishes to negotiate these terms. We argue that the complexity of mediated energy distribution and its convoluted stakeholder relationships requires more sophisticated methods of inquiry to engage people in debates concerning distributed energy systems.
