PurposeThis study investigated the impact of the perceived Augmented Reality (AR) social experience of restaurant menus on two types of prosocial behaviors: brand positivity and brand information sharing.Design/methodology/approachThis study adopts the expectancy-value model as a framework, drawing on the cognitive load, self-determination, and media richness theories. Using a sample of 879 participants from the United States, the research model was tested using structural equation modeling (PLS-SEM).FindingsThe findings indicate that the social experience derived from using AR menus significantly predicts brand positivity and brand information sharing. The perceived usefulness of AR mediates this relationship. Moreover, AR reality congruence acts as a significant mediator between perceived AR social experience and brand positivity but not brand information sharing. The positive relationship between AR social experience, brand positivity, and brand information sharing is sequentially mediated by AR reality congruence and AR usefulness.Originality/valueThis groundbreaking research pioneers a fresh perspective, delving into the impact of AR social experiences on consumers' prosocial behaviors, specifically brand positivity and information sharing. Unravels intricate mechanisms, shedding light on how and under what circumstances AR social experiences foster positive behaviors within the dynamic realm of food services and restaurant settings. This study provides valuable insights for restaurant managers and marketers to leverage AR technology to create engaging and immersive customer-dining experiences, a concept that has not been thoroughly explored in previous studies.
