　　　图1是本发明移动设备查看演示文档的方法的流程示意图；
　　　图2是本发明移动设备查看演示文档的系统的结构示意图；
　　　图3是本发明移动设备查看演示文档的系统的一个实施例的结构示意图；
　　　图4是本发明移动设备查看演示文档的系统的另一个实施例的结构示意图。
 本发明的实施方式
　　　请参阅图1，图1是本发明移动设备查看演示文档的方法的流程示意图。
　　　所述移动设备查看演示文档的方法包括以下步骤：
　　　步骤S101，根据重力感应器的感应信号判断屏幕方向；
　　　在用户选择用文档处理软件(例如WPS)等打开演示文档的同时，启动本发明的移动设备查看演示文档的方法。
　　　首先，获取移动设备的重力感应器的感应信号，根据所述感应信号判断当前移动设备的屏幕方向是横屏或者竖屏。现有技术中根据移动设备的重力感应器的感应信号判断屏幕方向的方法较为成熟，在此并不列举本发明执行此步骤的具体判断方法。
　　　步骤S102，当屏幕方向为竖屏时，将所述演示文档的幻灯片缩略图显示在屏幕下侧，水平分布；
　　　当判断屏幕方向为竖屏时，即用户的观赏角度一般也变成竖屏方向，此时，将所述演示文档包含的幻灯片的缩略图显示在屏幕下侧，水平分布。
　　　特别地，由于显示缩略图的同时会显示幻灯片的正文，而幻灯片正文通常显示在屏幕中部，并且显示的大小比缩略图要大很多，因此，可将幻灯片正文显示在屏幕中部或者上侧，缩略图显示在屏幕下侧，幻灯片正文之外的位置。
　　　因为屏幕方向为竖屏，缩略图显示在屏幕下侧，因此屏幕中部和上侧仍然留有很大的空位，缩略图的显示不会占用演示文档幻灯片正文的显示位置，用户可以通过点击显示在下侧的缩略图进行幻灯片的显示切换。
　　　步骤S103，当屏幕方向为横屏时，将所述演示文档的幻灯片缩略图显示在屏幕左侧或右侧，垂直分布。
　　　当判断屏幕方向为横屏时，即用户的观赏角度一般也变成横屏方向，此时，将所述演示文档包含的幻灯片的缩略图显示在屏幕左侧或右侧，垂直分布。
　　　同样，可将幻灯片正文显示在屏幕中部，缩略图显示在屏幕左侧或右侧，幻灯片正文之外的位置。因为屏幕方向为横屏，缩略图显示在屏幕左侧或右侧，因此屏幕中部仍然留有很大的空位，缩略图的显示不会占用演示文档幻灯片正文的显示位置，用户可以通过点击显示在左侧或右侧的缩略图进行幻灯片的显示切换。
　　　本发明的移动设备查看演示文档的方法在用户打开演示文档时，根据重力感应器的感应信号判断屏幕方向，在竖屏时，将所述演示文档的幻灯片缩略图显示在屏幕下侧，水平分布；在横屏时，将所述演示文档的幻灯片缩略图显示在屏幕左侧或右侧，垂直分布。因此，可以根据不同的屏幕方向，以更适合的方式显示，方便用户查看以及操作。并且本发明的方法中的显示方式更加符合用户的心理预期，能够带来更好的用户体验。
　　　在一个实施例中，当屏幕方向为竖屏时，进一步将幻灯片的切换方式设置为左右滑动切换；当屏幕方向为横屏时，进一步将幻灯片的切换方式设置为上下滑动切换。
　　　竖屏时，幻灯片缩略图显示在屏幕下侧，水平分布，幻灯片显示在屏幕中部或者上侧，因此，其切换方式设置为左右滑动切换，则滑动切换时不会遮挡幻灯片正文的显示；同样，横屏时，幻灯片缩略图显示在屏幕左侧或右侧，垂直分布，因此，其切换方式设置为上下滑动切换，则滑动切换时不会遮挡幻灯片正文的显示。
　　　在另一个实施例中，当屏幕方向为竖屏时，进一步将幻灯片的显示模式切换为肖像模式；当屏幕方向为横屏时，进一步将幻灯片的显示模式切换为风景模式。通过上述方法，在移动设备的屏幕方向改变时，进一步实现幻灯片的显示模式的自适应切换以更合适的幻灯片显示方式向用户展示，进一步提高用户体验。
　　　请参阅图2，图2是本发明移动设备查看演示文档的系统的结构示意图。

　　　当判断屏幕方向为竖屏时，即用户的观赏角度一般也变成竖屏方向，所述缩略图显示切换模块12将所述演示文档包含的幻灯片的缩略图显示在屏幕下侧，水平分布。
　　　特别地，由于显示缩略图的同时会显示幻灯片的正文，而幻灯片正文通常显示在屏幕中部，并且显示的大小比缩略图要大很多，因此，所述缩略图显示切换模块12可将幻灯片正文显示在屏幕中部或者上侧，缩略图显示在屏幕下侧，幻灯片正文之外的位置。
　　　因为屏幕方向为竖屏，缩略图显示在屏幕下侧，因此屏幕中部和上侧仍然留有很大的空位，缩略图的显示不会占用演示文档幻灯片正文的显示位置，用户可以通过点击显示在下侧的缩略图进行幻灯片的显示切换。
　　　当判断屏幕方向为横屏时，即用户的观赏角度一般也变成横屏方向，此时，所述缩略图显示切换模块12将所述演示文档包含的幻灯片的缩略图显示在屏幕左侧或右侧，垂直分布。
　　　同样，所述缩略图显示切换模块12可将幻灯片正文显示在屏幕中部，缩略图显示在屏幕左侧或右侧，幻灯片正文之外的位置。因为屏幕方向为横屏，缩略图显示在屏幕左侧或右侧，因此屏幕中部仍然留有很大的空位，缩略图的显示不会占用演示文档幻灯片正文的显示位置，用户可以通过点击显示在左侧或右侧的缩略图进行幻灯片的显示切换。
　　　本发明的移动设备查看演示文档的系统在用户打开演示文档时，所述方向感应模块根据重力感应器的感应信号判断屏幕方向；所述缩略图显示切换模块在竖屏时，将所述演示文档的幻灯片缩略图显示在屏幕下侧，水平分布；在横屏时，将所述演示文档的幻灯片缩略图显示在屏幕左侧或右侧，垂直分布。因此，可以根据不同的屏幕方向，以更适合的方式显示，方便用户查看以及操作。并且本发明的方法中的显示方式更加符合用户的心理预期，能够带来更好的用户体验。
　　　请参阅图3，图3是本发明移动设备查看演示文档的系统的一个实施例的结构示意图。

　　　竖屏时，幻灯片缩略图显示在屏幕下侧，水平分布，幻灯片显示在屏幕中部或者上侧，因此，所述幻灯片滑动切换模块13将其切换方式设置为左右滑动切换，则滑动切换时不会遮挡幻灯片正文的显示；同样，横屏时，幻灯片缩略图显示在屏幕左侧或右侧，垂直分布，其切换方式设置为上下滑动切换，也滑动切换时不会遮挡幻灯片正文的显示。
　　　请参阅图4，图4是本发明移动设备查看演示文档的系统的另一个实施例的结构示意图。
　　　在另一个实施例中，本发明的移动设备查看演示文档的系统进一步包括显示模式切换模块14，所述显示模式切换模块14用于在屏幕方向为竖屏时，将幻灯片的显示模式切换为肖像模式；在屏幕方向为横屏时，将幻灯片的显示模式切换为风景模式。在移动设备的屏幕方向改变时，通过所述显示模式切换模块14进一步实现幻灯片的显示模式的自适应切换以更合适的幻灯片显示方式向用户展示，进一步提高用户体验。
