Abstract

Menu research has focused predominantly on linear menus (e.g., cascading menus). Little is known about user behavior with radial menus, which have been around for some time. The paper investigates the order in which users find items in radial menus. We analyze data collected in a controlled experiment and define serial position for items laid out in a circular fashion. For the first level (ring), the serial positions start at 12 o'clock position and alternate between both sides of the ring. For subsequent levels, the serial positions follow distance from a parent item. The defined search pattern yields strong fit and has substantial effect on search performance. We discuss the results in the context of radial menu design.
