Mobile devices are used for various applications. Although graphical user interfaces (GUIs) are commonly employed to operate applications, situations exist in which GUIs cannot be used effectively. Mobile devices also support other types of user interfaces (UIs), including voice UIs and gesture-based UIs, such as shake interfaces. Placeona-a model that identifies the status of the user's eyes, hands, ears, and mouth when interacting with an application-was proposed to better adapt UIs to the user context. Based on placeona, we propose a method to develop adaptive user interfaces (PlaceonaUI) that detect a user's current context and dynamically switch to the most appropriate UI. Our method defines specific contexts using the status of the user's sensory and motor capabilities and establishes rules for UI switching. Furthermore, we developed a support system for creating the PlaceonaUI. The proposed PlaceonaUI and support system were implemented and evaluated to confirm their effectiveness.
