  Abstract: Social participation is known to bring great benefits to the health and well-being of people as they age. From being in contact with others to engaging in group activities, keeping socially active can help slow down the effects of age-related declines and reduce risks of loneliness and social isolation and even mortality in old age. There are unfortunately a variety of barriers that make it difficult for older adults to engage in social activities on a regular basis. In this chapter, we give an overview of the challenges to social participation and discuss how technology can help overcome these barriers and promote participation in social activities. We examine two particular research threads and designs, exploring ways in which technology can support colocated and virtual participation: (i) an application that motivates the virtual participation in group training programs and (ii) a location-based game that supports colocated intergenerational ICT training classes. We discuss the effectiveness and limitations of various design choices in the two use cases and outline the lessons learned.
