METHOD AND MULTIMEDIA DEVICE FOR INTERACTING USING USER INTERFACE BASED ON TOUCH SCREEN

摘要

The present invention relates to a user interface (UI) interaction method for implementing a method of switching between application screens by dragging on a touchscreen of a multimedia terminal device, and a multimedia terminal device. The touchscreen-based user interface interaction method detects a dragging motion which started from a certain area in the touchscreen while a first application screen is displayed, and overlays a second application screen on the first application screen.
