Abstract
In a user interface method, system and device in a multitasking environment, all applications being executed are displayed. Movement between applications being displayed and selection of the applications can be performed in response to a request from a user, such that the user can easily use applications being executed currently. Currently selected applications do not block other applications, and the user is able to simultaneously view all applications. The sizes and positions of the display areas assigned to the applications are determined based on stored feature values of each respective application, the entire display screen area being partitioned based on the feature values. The system comprises a set-top box and a user terminal, or a controller and a storage unit.
