Internet addiction emerges as a substantial health and well-being issue in children. Research suggests that software-mediated interventions may help address the problem; however, there is a gap in investigating the designs and considerations from the perspectives of children and parents, who are the primary stakeholders. The present study aims to co-design digital tools to protect young children from internet addiction. We involved 24 participants (children and parents) in 3 serial workshops: (1) conceptualising potential efforts through focus group discussion, (2) designing digital tools through card-based ideation, and (3) evaluating ideas through mixed-method testing. Our study contributes to conceptualising seven themes of potential efforts and producing 18 digital tool features categorised into eight functions. We discovered the promising potential of digital tools as parent-child dyadic interventions to encourage real-world interests, promote positive online activities, schedule balanced activities, provide online rules as playful missions with constructive consequences, and assist parental mediation decision-making.

Digital technology has great potential to support human health, including the complex needs of older adults in aged care services and treatments. This scoping review aims to explore the current state and roles of digital technology in supporting aged care following the PRISMA-ScR guidelines. We included 47 studies from the last 10 years covering five databases discussing the development, implementation, evaluation, or review of digital technology in aged care services and the broader clinical system. Seven key roles of digital technology were identified, including health monitoring and assessment, remote healthcare services, assistive technology to support treatment, self-care management, social technology to facilitate interaction, clinical decision support, and aged care quality measurement carried out by twelve technology types. Our findings show the potential of digital technology in enhancing the capability and efficiency of aged care services for developing or improving socio-technical aged care systems. We conclude with six recommendations for future research.
