Embodiment 1

[0017] Embodiment 1: In this embodiment, the focus receives an instruction to move the position from recommended position A to recommended position B, calculates the distance S from position A to position B, obtains the length and width of the selection box for recommended position A, and obtains the selection of recommended position B The length and width of the frame, calculate the length difference a and width difference b, set the time to move from A to B as T, and focus the selection frame with S / T

[0018] The speed of moving from the recommended position A to the recommended position B, while the length of the selection box changes at the speed of a / T, and the width changes at the rate of b / T. The frame rate for drawing the focus selection frame is more than 35 frames to meet the smooth condition of visual cognition, and the moving time T is set to 150ms.

[0019] The implementation of focus sliding deformation is shown in the figure. After B acquires the focus, the foc...

Embodiment 2

[0020] Embodiment 2: In this embodiment, the focus receives an instruction to move from the A recommended position to the B recommended position, calculates the distance S from the A position to the B position, obtains the length and width of the B recommended position selection box, and sets it to move from A The time to B is T, the focus selection box first directly changes to the size of the selection box of the B recommendation position, and then moves from the A recommendation position to the B recommendation position at the speed of S / T. The frame rate for drawing the focus selection frame is more than 35 frames to meet the smooth condition of visual cognition, and the moving time T is set to 150ms.

Embodiment 3

[0021] Embodiment 3: In this embodiment, the focus receives an instruction to move the position from recommended position A to recommended position B, calculates the distance S from position A to position B, obtains the length and width of the selection box for recommended position A, and obtains the selection of recommended position B The length and width of the frame, calculate the length difference a and width difference b, set the time to move from A to B as T, and focus the selection frame at 2S / T 2 The acceleration moves from the A recommended position to the B recommended position with uniform acceleration or deceleration, and its shape gradually changes to the shape and size of the B recommended position. The change rate of the length of the selection box is 2a / T 2 The rate of change, the rate of change of width is 2b / T 2 rate of change. The frame rate for drawing the focus selection frame is more than 35 frames to meet the smooth condition of visual cognition, and th...

Abstract

The invention discloses a deformable movement method of a focus point in a digital TV. The method comprises the following steps: receiving a focus point moving instruction, acquiring selection frame size and position of each of the current focus point and the target focus point; moving the selection frame to the target focus point from the current focus point within the time T, wherein the size of the selection frame is gradually changed as the size of the target selection frame. By use of the deformable movement method disclosed by the invention, the individual and special focus point movement effect in sliding deformation is realized, so that a user can quickly find out the position of the focus point on a screen.

Description

technical field [0001] The invention relates to a method for moving focus in a digital TV browser. Background technique [0002] The so-called focus in digital TV refers to the position where the cursor on the current browser interface is activated. If the cursor at a certain position is activated, it means that the control at this position is selected and can be operated. In the current technology, the four direction keys of up, down, left and right can be used to move the focus. After the focus is moved to a certain control icon, a rectangular selection box will be displayed to indicate that the current focus is on this icon. , when the focus moves, the current selection box disappears, and jumps to the target position to redisplay the selection box. The current problem is that the icons on the browser interface usually display the content of TV programs, and there are many graphic elements on the entire TV display interface. Users often cannot see the position of the foc...
