Older adults having limited experience with modern computing technology may find it difficult to learn touch gestures, especially the more complex rotate gesture. Social interactions, as implied by social constructivism, are assumed to be powerful in enabling older adults to acquire the skill of touch gestures. The social effect can be reinforced with the motivational effect of digital games. To verify the assumption, we conducted empirical studies with 59 older adults, who were divided into two groups: 17 Singles and 21 Dyads. They were asked to play a set of digital games on a multi-touch tabletop. Results show that on average Dyads have spent significantly longer time in the games and have performed a significantly higher number of correct rotate gestures than Singles. Future work focuses on analyzing the emotional aspect of social interactions and identifying further applications of social gaming to other ageing issue
