Embodiment Construction

[0033] At first, explain control method and principle of the present invention:

[0034] (1) Control program

[0035] Such as figure 1 As shown, the horizontal and vertical screen switching gradient control process of the present invention specifically includes the following steps:

[0036] 101) Determine whether the orientation of the screen has changed based on gravity sensing? Yes, go to the next step, otherwise return to step 101);

[0037] 102) Play an animation from clear to blurry according to the original interface image;

[0038] 103) Freeze the screen, interface layout, and obtain the interface image after switching direction;

[0039] 104) Play an animation from blur to clear according to the acquired interface image, and unfreeze the screen.

[0040] (2) Principles of animation

[0041] 2.1) The principle of brightness gradient

[0042] It is to draw a RGB=black (0,0,0) figure when displaying the draw method of the layer object layer, but it has a transparen...

Abstract

The invention relates to a gradual change control method for transverse / vertical screen switch of a handheld device, which comprises performing sequential calculation according to setting times and successively displaying an upper-layer full back image with transparency AI ranging from = 0 to =1 and a lower-layer continuously blurry interface image before direction switching; freezing the screen to obtain an interface image after the direction switching; performing calculation and storage according to setting times and successively displaying an upper-layer full back image with transparency AI ranging from =1 to =0 and a stored lower-layer continuously clearing interface image after the direction switching in a reversed order; displaying the interface image after the direction switching and unfreezing the screen; and calculating pixel values and light intensity of four or eight pixel points of mixed peripheries, and performing averaging. The control method can perfectly link up rotating movements of users and provide the users realistic natural experience.

Description

technical field [0001] The invention relates to computer human-computer interaction, in particular to a method for controlling gradual change of horizontal and vertical screen switching of a handheld device, especially applied to a smart phone. Background technique [0002] At present, the smart phones of the existing mobile terminals only have the function of switching between the horizontal and vertical screens and do not have the function of displaying switching animations during the switching between the horizontal and vertical screens. In the case of screen orientation changes, there is a switching animation effect, especially in the case of gravity sensing, there is a natural rotation animation to match the user's movement of rotating the phone, so that the user will not feel the effect of the interface being blunt and can give the user unlimited Nice experience. However, the current mobile phones or other handheld devices do not have a perfect transition animation wh...
