A touch display device including a user interface and a processor is provided. The user interface is for generating a plurality of touch sensing signals and a plurality of drag signals, wherein each drag signal includes information of a touch start position and a touch end position. The processor is configured to generate a plurality of drag vectors using the drag signals by calculating a relative distance and drag direction from the touch start position to the touch end position, determine if the touch sensing signals and the drag vectors match a predetermined condition, and, based on the determination, perform an application program to generate a virtual object displayable on the user interface and control the virtual object in a pilot mode or a settings mode.
