Abstract
In recent years, 3D gesture operation is just beginning to be implemented on PC. As of now, 3D gesture operation doesn’t have common and general definitions in the world and each vender assigns her own gestures in an original way. However, this causes inconsistent operations which confuse users even though the consistency is one of the most important matter for better user experience. So, we aimed to build common design policy for 3D gestures of UI operation. In this design policy, we try to provide both design guidelines and design patterns.
