There have been recently several input methods that combine pen-based input with a pie menu as an input interface in environments where working space is limited. However, they suffer from various problems in that input operation is difficult to learn where there are many items on the menu. In this research, we propose a new space-saving input interface that combines an analog joystick and a hierarchical pie menu. The proposed method employs a hierarchical pie menu to enhance the number of items, and a frequency-based area division algorithm that works to expand the area for important items. Using our method, an intuitive input interface is achieved that is high speed and highly accurate.
