It is understood by those skilled in the art that the coordinates of another set of diagonal vertices (ie, the upper left corner and the lower right corner) of the floating menu 22 may also be used in the specific implementation, which is not limited by the present invention.

In another preferred embodiment, the element is a regional element. The area element is an element occupying a certain area in a whiteboard page, and the area is preferably a rectangular area.

When the element is a region element, the step S1 is specifically:

As shown in FIG. 2, the area element may be the text box 24 in the whiteboard page 21. The coordinates of a set of diagonal vertices of the area element 24 obtained in this embodiment are the upper right corner E (x ₃ , y ₃ And the lower left corner F(x ₄ , y ₄ ), the coordinates of a set of diagonal vertices of the floating menu 22 obtained are the upper right corner B(x ₁ , y ₁ ) and the lower left corner C(x ₂ , y ₂ ) .

In order to further improve the sensitivity and reliability of the collision detection, a collision interval value may be set in advance, and when the distance between the point element and the floating menu is less than the collision interval value, it is determined that the two collide. The step S2 is specifically:

As shown in FIG. 2, if the element is a point element A, that is, in a specific implementation, when x ₀ ∈[x ₂ -d, x ₁ +d] is detected, and y ₀ ∈[y ₁ -d,y _{When 2} +d], it is determined that the two collide, and the floating menu needs to be moved; otherwise, it is determined that there is no collision between the two, and there is no need to move the floating menu. Where d is a preset collision interval value.

If the element is a region element 24, ie in a specific implementation, when detected and

Further, the step S3 includes:

The floating menu is shifted to the right when the element is located on the left half of the electronic whiteboard page and the right side of the floating menu has a page space available for the floating menu to move.

The floating menu is shifted to the left when the element is located on the right half of the electronic whiteboard page and the left side of the floating menu has a page space available for the floating menu to move.

The floating menu is moved down when the element is located on the upper half of the electronic whiteboard page and the page below the floating menu has a page space available for the floating menu to move.

In a specific implementation, the height h and width w of the floating menu and the maximum coordinate M(x _m , y _m ) of the electronic whiteboard page are combined, and the position coordinates of the floating menu are combined to determine the circumference of the floating menu. Whether there is room for it to move. Specifically, if w<x _m -x ₂ , it means that the right side of the floating menu has a page space for moving, and can move to the right side when the floating menu needs to be moved. If w<x ₁ , it means that the left side of the floating menu has a page space for moving, and can move to the left when the floating menu needs to be moved. If h<y _m -y ₁ , it means that the page below the floating menu has a page space for moving, and can move downward when the floating menu needs to be moved. If h<y ₂ , it means that the top of the floating menu has a page space for moving, and can move upward when the floating menu needs to be moved.

The present invention also determines the moving direction of the floating menu by obtaining the position of the element in the electronic whiteboard page. In a specific implementation, the position of the element in the electronic whiteboard page (ie, the upper, lower, left, and right half sides) can be determined by the position of the geometric center of the element in the electronic whiteboard page. Specifically, when the center of the element is located on the left half of the electronic whiteboard page, that is, when the x coordinate of the element center is less than x _m /2, the floating menu is shifted to the right. Conversely, when the center of the element is located on the right half of the electronic whiteboard page, that is, when the x coordinate of the center of the element is greater than x _m /2, the floating menu is shifted to the left. Similarly, when the element center is located on the upper half of the electronic whiteboard page, that is, when the y coordinate of the element center is less than y _m /2, the floating menu is moved down. Conversely, when the center of the element is located on the lower half of the electronic whiteboard page, that is, when the y coordinate of the center of the element is greater than y _m /2, the floating menu is moved up. The floating menu moves the distance so that the distance between the floating menu and the element is slightly larger than the preset collision interval, which is not limited by the present invention, and can be set according to specific needs by those skilled in the art. As shown in FIG. 2, when the element is a point element A, the coordinates of the center of the element are the same as the coordinates of the point element, and both are (x ₀ , y ₀ ). And when the element is the area element 24, the coordinates of the center of the element are ((x ₃ + x ₄ )/2, (y ₃ + y ₄ )/2) or (x ₄ + w _A /2, y ₃ +h _A /2), where w _A is the width of the region element and h _A is the height of the region element.

In the specific implementation, it is possible to first determine whether to move left and right, and when it is impossible to avoid the collision by moving left and right, then to judge whether to move up and down; or to determine whether to move up and down, if it is impossible to move up and down to avoid collision, then proceed Judgment of moving left and right. More preferably, the moving directions of the up, down, left, and right directions can be simultaneously judged, and the final moving direction of the floating menu is the vector superposition of the judgment results of the four directions.
