This paper presents a selection of game design concepts to promote social interaction between older people and players from other generations. Hardware-related interaction channels, game mechanics and game content can be used to trigger positive communication between several players. The proposed concepts are based on the experience of 32 game prototypes developed with and for the oldest seniors living in several Swiss nursing and retirement homes. The games are directed at the relatives to make their visits a pleasant and positively perceived experience, with the aim of increasing well-being of all involved.

Large Interactive Displays (LIDs), such as tabletops or interactive walls, are promising innovations, which are increasingly used to support co-located collaboration. Yet the current evidence base on the impact of LID use on collaborative processes and outcomes, and associated influencing factors, is fragmented, particularly in comparison with other media. To address this gap, a systematic review was carried out in the databases Web of Science, Psych.Info, ACM, Elsevier, JSTOR and Springer and in the ACM CHI conference database. A corpus of 38 articles with experimental study designs met the eligibility criteria and was analyzed in-depth. With regard to collaboration processes, the findings suggest a relatively clear advantage of the use of LIDs over classic forms of collaboration, in particular over single-user environments (e.g. laptops). With attention to collaborative outcomes, positive effects of LIDs were identified for knowledge gains and social encounters, and mixed effects for task-related outcomes. The analysis further shows relevant influencing factors of LID, such as the separation of personal and joint work spaces and the deployment of horizontal instead of vertical displays. Conceptual and practice implications are discussed.
