Aging is a natural process that brings social and physical challenges among adults, due to which they have to make shifts in habits and routines. Adults belonging to an older age group lose touch with people which provides an opportunity for researchers to think and implement novel ways to engage the population with their loved ones. The advent of technology within the Mixed Reality (MR) space aims to facilitate diverse groups of people to engage in immersive and interactive ways, opening possibilities to address the predicament of aging in an isolated environment. Utilizing participatory design in a virtual setting, inclusive design frameworks and design thinking practices, the contributions of this research are to present the broad concepts of storytelling, social engagement and Mixed Reality existing in the literature, and then take inspiration to co-design a Mixed Reality storytelling system with older adults and their friends & family for the purpose of cultivating meaningful social connections through sharing stories.
