Z-force cubic interface is a 3D interface using the cube as a core design element and utilizing z-force touch as the general interaction medium. Unlike previous research conducted to provide the 3-dimensional interface or new ways of controlling interfaces, z-force cubic interface combines effective mediums to provide intuitive and real-life like control of virtual mobile space. A prototype was produced to conduct heuristic research on the concept and several z-force touch gestures with high applicability were chosen as a controlling system. 3D navigation of the cube, zooming in and out, and unconstrained manipulation of application mimics real word interactions, leading to improvements in usability. Utilizing the 3D cube to see 360-degree photos or videos and sending VR emotions pulled down the boundaries between the conventional interface and reality. Interactive feedback of incoming alerts and notifications by rotation or resizing the cube itself works as an intuitive and entertaining factor for operating mobile space. Z-force cubic interface, as a whole, tries to give users a novel opportunity of experiencing the real world in a virtual mobile space without additional equipment, such as VR gadgets.
