当所述元素位于所述电子白板页面的下半侧，并且所述悬浮菜单的上方具有可供所述悬浮菜单移动的页面空间时，将所述悬浮菜单上移。
在具体实施当中，可通过获取悬浮菜单的高度h和宽度w以及电子白板页面的最大坐标M(xm，ym)，并结合所述悬浮菜单的位置坐标，以判断所述悬浮菜单的四周是否具有可供其移动的空间。具体地，若w＜xm-x2，则说明所述悬浮菜单的右方具有可供其移动的页面空间，在需要移动悬浮菜单时可向右侧移动。若w＜x1，则说明所述悬浮菜单的左方具有可供其移动的页面空间，在需要移动悬浮菜单时可向左侧移动。若h＜ym-y1，则说明所述悬浮菜单的下方具有可供其移动的页面空间，在需要移动悬浮菜单时可向下移动。若h＜y2，则说明所述悬浮菜单的上方具有可供其移动的页面空间，在需要移动悬浮菜单时可向上移动。
本发明还通过获取元素在电子白板页面中所处的位置来判断悬浮菜单的移动方向。在具体实施当中，所述元素在电子白板页面中所处的位置(即上、下、左、右半侧)，可通过所述元素的几何中心在所述电子白板页面中的位置来判断。具体地，当所述元素的中心位于所述电子白板页面的左半侧，即当元素中心的x坐标小于xm/2时，则将所述悬浮菜单右移。反之，当所述元素中心位于所述电子白板页面的右半侧，即当元素中心的x坐标大于xm/2时，则将所述悬浮菜单左移。同理地，当所述元素中心位于所述电子白板页面的上半侧，即当元素中心的y坐标小于ym/2时，则将所述悬浮菜单下移。反之，当所述元素中心位于所述电子白板页面的下半侧，即当元素中心的y坐标大于ym/2时，则将所述悬浮菜单上移。所述悬浮菜单移动的距离，以使得悬浮菜单与元素之间的距离稍大于预设的碰撞间隔为准，本发明对此不
作限定，本领域技术人员可根据具体需要进行设置。如图2所示，当所述元素为点元素A时，所述元素中心的坐标与所述点元素的坐标相同，均为(x0，y0)。而当所述元素为区域元素24时，则所述元素中心的坐标为((x3+x4)/2，(y3+y4)/2)或者(x4+wA/2，y3+hA/2)，其中，wA为所述区域元素的宽度，hA为所述区域元素的高度。
在具体实施当中，既可以先判断是否进行左右移动，当无法通过左右移动躲避碰撞后，再进行上下移动的判断；也可以先判断是否进行上下移动，当无法通过上下移动躲避碰撞后，再进行左右移动的判断。更优地，可同时对上下左右的移动方向进行判断，此时悬浮菜单的最终移动方向为四个方向判断结果的向量叠加。
本发明通过移动方向的判断，可获取悬浮菜单的最优移动路径，有利于实现对白板页面的最优化利用。采用本发明提供悬浮菜单的自动移动方法，在电子白板页面上有悬浮菜单存在的情况下，用户在白板上进行书写操作，当书写至菜单附近时，若发现书写点与菜单有碰撞，则此时菜单将自动判断移动方向并进行移动，用户可以继续进行书写，从而提升用户在书写方面体验。
参见图3，是本发明提供的悬浮菜单的自动移动装置的一个实施例的结构图。本实施例的基本原理与图1所示实施例一致，本实施例中未详述之处可参见图1所示实施例中的相关描述。
如图3所示，所述悬浮菜单的自动移动装置包括：
坐标获取模块31，用于获取电子白板页面中的元素以及悬浮菜单的实时位置坐标。
碰撞检测模块32，用于根据获取的所述元素以及所述悬浮菜单的位置坐标，判断所述元素是否与所述悬浮菜单发生碰撞。
菜单移动模块33，用于在发生碰撞时，将所述悬浮菜单移动至不与所述元素发生碰撞的位置。
在一种优选的实施方式当中，所述元素为点元素。具体地，所述点元素可以为笔迹的当前书写点。
所述坐标获取模块31包括第一坐标获取单元311，用于获取所述点元素的坐标以及所述悬浮菜单的一组对角顶点的坐标。
在另一种优选的实施方式当中，所述元素为区域元素。具体地，所述区域元素可以为文本框。
所述坐标获取模块31包括第二坐标获取单元312，用于获取所述区域元素的一组对角顶点的坐标以及所述悬浮菜单的一组对角顶点的坐标。
所述碰撞检测模块32包括碰撞检测单元321，用于根据获取的所述元素以及所述悬浮菜
单的位置坐标，判断所述元素与所述悬浮菜单之间的距离是否小于预设的碰撞间隔值；若是，则判定所述元素与所述悬浮菜单发生碰撞；若否，则判定所述元素与所述悬浮菜单未发生碰撞。进一步地，所述菜单移动模块33包括：
右移单元331，用于当所述元素位于所述电子白板页面的左半侧并且所述悬浮菜单的右方具有可供所述悬浮菜单移动的页面空间时，将所述悬浮菜单右移。
左移单元332，用于当所述元素位于所述电子白板页面的右半侧并且所述悬浮菜单的左方具有可供所述悬浮菜单移动的页面空间时，将所述悬浮菜单左移。
下移单元333，用于当所述元素位于所述电子白板页面的上半侧并且所述悬浮菜单的下方具有可供所述悬浮菜单移动的页面空间时，将所述悬浮菜单下移。
上移单元334，用于当所述元素位于所述电子白板页面的下半侧并且所述悬浮菜单的上方具有可供所述悬浮菜单移动的页面空间时，将所述悬浮菜单上移。
综上所述，现有方案当中，若电子白板页面中的元素与页面中的悬浮菜单发生冲突碰撞时，必须要手动移动菜单或放弃菜单区域，页面利用率较低，书写体验较差。本发明通过获取电子白板页面中的元素以及悬浮菜单的实时位置坐标。根据获取的位置坐标，判断所述元素是否与所述悬浮菜单发生碰撞。在发生碰撞时，将所述悬浮菜单移动至不与所述元素发生碰撞的位置。采用本发明，可在页面元素与悬浮菜单发生冲突时自动调整悬浮菜单的位置，以充分利用被悬浮菜单遮挡的页面区域，有利于提高书写的效率，改善书写体验。
