HUMAN COMPLEMENTARY MENU DESIGN FOR MOBILE PHONES

This study proposes user control and system support as means to facilitate system-driven and user-driven interface adaptations of mobile phones. A hypothetical prototype of mobile phone menu with an additional collection of quickly accessible items, which is called 'hotlist,' was implemented. An experiment was conducted for the evaluation of five different menu types: traditional (T), adaptable (B), adaptable with system support (Bs), adaptive (V), and adaptive with user control (Vc). The results showed that providing the system support to the adaptable menu not only increased the users' perception of the efficiency of selection, but also reduced the menu adaptation time.
