This paper presents a scoping review of intergenerational active play to provide an overview of current research in HCI and related disciplines. Play has been widely perceived as a common activity among people of all ages. Physical activity and active play are essential to positive developmental outcomes, especially of those in preschool years. Intergenerational play can be beneficial to people of different generations by promoting meaningful interactions and healthy relationships. Finally, intergenerational active play shows great potential in fostering early childhood development and positive ageing for older adults. Digital technology provides opportunities for promoting intergenerational active play in new ways, such as digital games, exergames, and tangible embodied embedded interaction (TEIs). Based on the review, we present a framework for intergenerational active play which encapsulates the key concepts, challenges, and opportunities for future research and design.
