Method, apparatus and system for displayed content transfer between screens

摘要

The present invention is applicable to the field of multi-screen display technologies. The method includes: detecting a sliding track of a user on the primary screen display device, where the sliding track includes a sliding direction, and an initial position and a real-time position of sliding; determining, according to the initial position and the real-time position of the sliding, a display area of a screen of the secondary screen display device after the sliding by using the sliding direction as a reference direction; tailoring currently displayed content of the primary screen display device according to the display area, to obtain tailored content; and sending the tailored content and the display area to the secondary screen display device, so that the secondary screen display device displays the tailored content on the display area.

1. A method for displayed content transfer between screens, applied to a primary screen display device, wherein the primary screen display device is connected to a secondary screen display device, the method comprising:
detecting a sliding track of a user on the primary screen display device, wherein the sliding track comprises a sliding direction, an initial position and a real-time position of sliding; determining, according to the initial position and the real-time position of the sliding, a display area of a screen of the secondary screen display device after the sliding by using the sliding direction as a reference direction; tailoring currently displayed content of the primary screen display device according to the display area, to obtain tailored content; and sending the tailored content and the display area to the secondary screen display device, so that the secondary screen display device displays the tailored content on the display area; wherein determining, according to the initial position and the real-time position of the sliding, the display area of the screen of the secondary screen display device after the sliding by using the sliding direction as the reference direction comprises: calculating the following formulas:⁢B⁢⁢1⁢(x,y)=B⁢⁢1⁢(0,InitHeight_⁢2-Δ⁢⁢y×k×InitHeight_⁢2InitHeight_⁢1)B⁢⁢2⁢(x,y)=B⁢⁢2⁢(Δ⁢⁢x×k×InitWidth_⁢2InitWidth_⁢1,InitHeight_⁢2-Δ⁢⁢y×k×InitHeight_⁢2InitHeight_⁢1)⁢B⁢⁢3⁢(x,y)=B⁢⁢3⁢(0,InitHeight_⁢2)⁢B⁢⁢4⁢(x,y)=B⁢⁢4⁢(Δ⁢⁢x×k×InitWidth_⁢2InitWidth_⁢1,InitHeight_⁢2) wherein the sliding direction is the 2 o'clock direction, Δx=x2−x1, Δy=y2−y1, (x1, y1) represents an initial position of the sliding, (x2, y2) represents a real-time position of the sliding, InitWidth_1 represents a width of an initial display frame of a primary screen, InitHeight_1 represents a height of the initial display frame of the primary screen, InitWidth_2 represents a width of an initial display frame of a secondary screen, InitHeight_2 represents a height of the initial display frame of the secondary screen, and k represents a ratio between sliding displacement on the primary screen and a moving distance of displayed content on the primary screen.
