ABSTRACT 

The purpose of this study is to conduct basic research on development of game interface for the elderly byverifying the difference in user experience based on the type of interface. The methodology of playtestcombining experimental research and survey was applied with subjects of elderly users consisting of 47 men and48 women being ages 60 and up. The effects of user experience between natural user interface and the pad-typeinterface were compared and analyzed through repeated measure MANOVA in terms of emotional response,ease of use and flow. The NUI game showed higher emotional responses such as pleasure and dominance. Onthe other hand, there was no difference in arousal. The NUI game also presented higher ease of use in the processof game play and it also had higher autotelic experience, action-awareness merging, sense of control andambiguous feedback experience. These results may contribute to the development of serious game and naturaluser interface for the elderly by empirically identifying the effects of user experience on NUI.
