Embodiment Construction

[0037] First, describe the control method and principle of the present invention:

[0038] (1) Control program

[0039] like figure 1 As shown, the horizontal and vertical screen switching rotation control flow of the present invention specifically includes the following steps:

[0040] 101) Determine whether the screen orientation changes according to gravity sensing? Yes, go to the next step, otherwise return to step 101);

[0041] 102) Freeze the screen;

[0042] 103) interface layout, obtain the image of the interface after switching the direction;

[0043] 104) play the rotation animation according to the obtained image and the angle and direction of the switch; the playback rotation animation sub-process is as follows: image 3 shown;

[0044] 105) Unfreeze the screen (display the image after screen switching).

[0045] (2) Animation principle

[0046] 2.1) Determine whether the screen orientation has changed

[0047] Each time the screen orientation changes, th...

Abstract

The invention relates to a horizontal-vertical screen switching rotation control method for hand-held devices. The horizontal-vertical screen switching rotation control method includes the following steps: according to gravity sensing, a rotation direction and a switched angle Phi m are acquired; a screen is frozen, and a direction-changed interface image is acquired; the current angle Phi i of the interface image is calculated and displayed until Phi i is equal to Phi m, wherein Phi i is equal to Phi 0 plus (Phi n minus Phi 0) multiplied by Ai, Ai is equal to (m minus (m minus i) multiplied by (m minus i) divided by m) divided by m, m is the total number of rotation display times, i is the current number of rotation display times, and is greater than or equal to 1 and less than or equal to m, m and i are natural numbers, Ai is acceleration percentage, and the initial angles Phi 0, Phi i and Phi m are in the same rotation direction; the display of the hand-held device screen is not changed, the interface image is rotated around the central point of the screen on the surface of the screen, and the screen only displays the part of the rotated interface image, which is in the screen; and the screen is defrozen. The control method can perfectly connect the rotation act of a user and bring vivid natural experience to the user.

Description

technical field [0001] The invention relates to computer human-computer interaction, in particular to a horizontal and vertical screen switching rotation control method of a handheld device, especially applied to a smart phone. Background technique [0002] At present, the smart phone of the existing mobile terminal only has the function of switching between the horizontal and vertical screens and does not have the function of displaying the switching animation during the switching between the horizontal and vertical screens. In the case of screen orientation change, there is a switching animation effect, especially in the case of gravity sensing, there is a natural rotation animation to cooperate with the user's action of rotating the phone, so that the user will not feel the blunt effect of the interface, which can give the user unlimited Nice experience. However, current mobile phones or other handheld devices do not have a perfect connection animation when switching bet...
