下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
图1是本公开的一个实施例中一种内容的显示方法的示意性流程图，该方法可以应用于移动终端，也可以应用于其他终端设备，下面以应用于移动终端(如智能手机)为例进行详细说明。图1的方法可包括：
S101，获取人眼视线与显示屏的视线角，其中，可利用眼球追踪技术来确定人眼视线，人眼视线即人的眼球看向显示屏时眼球与显示屏之间的假想直线，当移动终端在空间移动时，人眼眼球随之偏移，人眼视线与垂直于显示屏所在平面的直线之间的夹角随之变化，通过前置摄像头实时采集人眼眼球偏移状态，进而确定人眼视线与垂直于显示屏所在平面的直线之间的夹角，即视线角；
以及，获取显示屏的朝向信息，其中，显示屏的朝向信息是指显示屏在 竖直方向上与人脸之间的相对位置关系，显示屏可以与人脸平行，还可能下端远离人脸，也可能上端远离人脸，可利用移动终端的内置陀螺仪来获取显示屏的朝向信息，实时采集陀螺仪的状态信息，进而确定显示屏的朝向信息。
S102，根据获取到的视线角和显示屏的朝向信息，对显示屏显示的内容进行转动显示，以使该内容与人眼视线垂直。
具体的，监测移动终端的显示屏以定位当前显示的内容，其中，该内容可以是移动终端本地存储的图片、网络上加载的图片，还可以是网页中的配图等。通过监测移动终端的显示屏，即可在显示屏的当前显示页面中定位到待调整的内容，待调整的内容可全屏显示于当前显示页面中，也可非全屏显示于当前显示页面中。
该步骤中，根据视线角和显示屏的朝向信息调整显示屏显示的内容时，若显示屏显示的内容所在平面与人眼视线不垂直，此时，需要根据视线角和显示屏的朝向信息分别确定在各方向上的旋转角度和旋转方向，最终，通过对显示屏显示的内容的自动调整使得该内容与人眼视线保持垂直，即使得显示屏相对于人眼视线发生偏移时仍能为用户呈现出最佳角度的内容，从而提高用户浏览显示屏显示的内容的体验度。
具体的，当定位到移动终端的显示屏上显示的内容、且人眼视线随显示屏移动时，能够根据人眼视线和显示屏的朝向信息来确定显示屏的偏移信息，包括在水平方向上的第一角度和在垂直方向上的第二角度，进而根据该偏移信息调整显示屏显示的内容，使得该内容的调整不仅仅局限于重力方向上的旋转，而是能够根据水平方向上和垂直方向上的偏移分别进行调整，从而使调整后的内容在水平方向和垂直方向上均能跟随人眼视线的移动，确保显示屏显示的内容呈现在人眼视线的最佳角度。
在本公开实施例中，基于视线角和显示屏的当前朝向，自动随着人眼视线变化适应性调整显示屏显示的内容的显示方位，并使得显示屏显示的内容与人眼视线始终保持垂直，无需用户手动调整移动终端的握持角度，能够自 动调整显示屏显示的内容与人眼视线的夹角，提高了调整精度，提升了用户观看体验。
下面，将结合具体的实施例，对本公开实施例的方法作进一步的描述。
在一个实施例中，需要预先建立显示屏的三维坐标系，其中，该三维坐标系包括第一坐标轴X轴、第二坐标轴Y轴、第三坐标轴Z轴，该三维坐标系随显示屏的移动而变化，但是，定义第一坐标轴和第二坐标轴始终位于显示屏所在平面，第三坐标轴始终垂直于显示屏所在平面，且显示屏的初始状态为显示屏的中心点与人眼位于同一水平面上、且显示屏位于竖直状态。
图2示意性地示出了显示屏的初始状态以及初始坐标系。如图2所示，假设人眼位于正前方，则显示屏200的初始状态为：显示屏200的中心点与人眼位于同一水平面上、且显示屏200位于竖直状态。其中，显示屏200位于竖直状态指显示屏200较长的一边与重力方向平行，较短的一边与第一坐标轴方向平行。以显示屏的中心点为原点，建立初始坐标系如图2中所示的X轴、Y轴及Z轴。其中，X轴的正方向为水平向右，Y轴的正方向为水平向上，Z轴的正方向为垂直于显示屏200的向外方向。
其中，根据移动终端的型号获取该移动终端的陀螺仪(重力传感器)的布局参数，根据该布局参数建立移动终端的初始三维坐标系，具体的，根据重力传感器和相机布局确定重力传感器与移动终端状态对应信息，以及相机与显示屏中心距离。以移动终端的显示屏中心与眼睛平齐且机身竖直状态为初始状态，假如，获取到的初始状态为X轴为0，Y轴为-9.8，Z轴为0，前置相机捕获到眼球信息为垂直屏幕；那么当移动终端的显示屏中心高度不变顺时针旋转90度时状态变为X/Y/Z：9.8/0/0，此时人眼视线与显示屏垂直，即Z轴与人眼视线夹角为0度。
另外，移动终端内置的陀螺仪(重力传感器)的安装位置尤其是正反面位置初始坐标系影响较大，如果重力传感器位于移动终端背面，则其Z轴与初始坐标系相同；如果重力传感器位于移动终端正面，则其Z轴方向与初始 坐标系相反，需要做归一化处理，将其对应关系存储于移动终端中，将归一化后的坐标系作为对应型号的移动终端的初始坐标系，即图2。
基于上述确定的初始坐标系，可确定人眼视线与Z轴之间的夹角作为显示屏在第一坐标轴方向上的第一角度，确定Z轴与重力方向(即竖直向下的方向)之间的夹角作为显示屏在第二坐标轴方向上的第二角度。显然，当人眼视线随显示屏移动时，若显示屏在第一坐标轴方向上发生偏移，则人眼视线与Z轴之间的夹角不为零，若显示屏在第二坐标轴方向上发生偏移(即显示屏不再处于竖直状态)，则Z轴与重力方向之间的夹角不为90度。
图3示意性地示出了显示屏在第一坐标轴方向上发生偏移时的第一角度。如图3所示，人眼300与显示屏200的中心点位于同一水平面上，在初始状态下，第一角度α为零，当显示屏200在该水平面上发生偏移时，第一角度α不为零，此时，显示屏200上显示的内容相对于人眼视线也发生偏移。具体的，若第一角度α不为零，说明显示屏在第一坐标轴方向上发生偏移(可能显示屏的左端远离人脸，也可能显示屏的右端远离人脸)，则需以第二坐标轴为中心调整显示屏显示的内容在第一坐标轴方向上的呈现角度；其中，若显示屏左端向内偏移(即左端远离人眼)，则第一角度α大于-90度且小于0度；若显示屏右端向内偏移(即右端远离人眼)，则第一角度α大于0度且小于90度。
图4示意性地示出了显示屏在第二坐标轴方向上发生偏移时的第二角度。如图4所示，显示屏200位于竖直状态时，第二角度β为90度，当显示屏200在第二坐标轴方向上发生偏移时，第二角度β不为90度，此时，显示屏200上显示的内容相对于人眼视线也发生偏移。具体的，若显示屏在第二坐标轴方向上的第二角度β不为90度，说明显示屏在第二坐标轴方向上发生偏移(可能显示屏的上端远离人脸，也可能显示屏的下端远离人脸)，则需以第一坐标轴为中心调整显示屏显示的内容在第二坐标轴方向上的呈现角度。其中，若显示屏上端向内偏移(即上端远离人眼)，则第二角度β大于90度； 若显示屏下端向内偏移(即下端远离人眼)，则第二角度β小于90度。
以下详细说明如何根据人眼视线及显示屏的朝向信息调整显示屏显示的内容。
其中，上述S102根据获取到的视线角和显示屏的朝向信息，对显示屏显示的内容进行转动显示，具体包括：
步骤一，根据获取到的视线角，确定人眼视线与预先建立的三维坐标系中第三坐标轴之间的第一夹角α，具体的，当视线角定义为人眼视线与垂直于显示屏所在平面的直线之间的夹角时，视线角即为第一夹角α；
步骤二，根据显示屏的朝向信息，确定重力方向与第三坐标轴正向之间的第二夹角β；
步骤三，针对三维坐标系中第一坐标轴和第二坐标轴，根据第一夹角和第二夹角，分别确定显示屏显示的内容的旋转角度以及旋转方向；具体的，根据第一夹角，确定显示屏显示的内容以第二坐标轴为中心在第一坐标轴上的旋转夹角和旋转方向，以及根据第二夹角，确定显示屏显示的内容以第一坐标轴为中心在第二坐标轴上的旋转夹角和旋转方向，其中，当第一夹角为0°时，在第一坐标轴上的旋转夹角为0°，当第二夹角为90°时，在第二坐标轴上的旋转夹角为0°，也就是说，当第一夹角为0°且第二夹角为90°时，不需要对显示屏显示的内容进行转动调整；
步骤四，基于确定出的旋转角度和旋转方向对显示屏显示的内容进行转动显示；具体的，在对显示屏显示的内容进行旋转显示时，分别将显示屏显示的内容以第二坐标轴为中心在第一坐标轴上进行旋转，和/或将显示屏显示的内容以第一坐标轴为中心在第二坐标轴上进行旋转，其中，当第一夹角为0°时，显示屏显示的内容在第一坐标轴上不需要旋转，当第二夹角为90°时，显示屏显示的内容在第二坐标轴上不需要旋转。
进一步的，考虑到显示屏显示的内容旋转显示前在显示屏上全屏显示，如果显示屏显示的内容在第一坐标轴上或第二坐标轴上进行旋转显示后，可 能存在内容不完全显示的情况，为了保证用户的人眼视线与显示屏显示的内容垂直的同时，确保用户能够完整观看显示屏显示的内容，基于此，在确定第一夹角和第二夹角之后，还包括：
步骤五，针对三维坐标系中第一坐标轴和第二坐标轴，根据第一夹角和第二夹角，分别确定显示屏显示的内容的显示尺寸的缩小系数；具体的，根据第一夹角，确定显示屏显示的内容在第一坐标轴上的显示尺寸的缩小系数(即显示屏显示的内容的宽度的缩小系数)，以及根据第二夹角，确定显示屏显示的内容在第二坐标轴上的显示尺寸的缩小系数(即显示屏显示的内容的长度的缩小系数)，其中，当第一夹角为0°时，在第一坐标轴上的缩小系数为0，当第二夹角为90°时，在第二坐标轴上的缩小系数为0，也就是说，当第一夹角为0°且第二夹角为90°时，不需要对显示屏显示的内容进行显示尺寸缩小调整；
步骤六，基于缩小系数对显示屏显示的内容的显示尺寸缩小显示，以使该内容完整显示；具体的，在对显示屏显示的内容进行显示尺寸缩小调整时，分别将显示屏显示的内容在第一坐标轴上进行显示尺寸缩小显示，和/或将显示屏显示的内容在第二坐标轴上进行旋转显示尺寸缩小显示，其中，当第一夹角为0°时，显示屏显示的内容在第一坐标轴上不需要进行显示尺寸缩小显示，当第二夹角为90°时，显示屏显示的内容在第二坐标轴上不需要进行显示尺寸缩小显示。
其中，针对确定在第一坐标轴和第二坐标轴上的旋转参数(旋转角度和旋转方向)的情况，具体的，上述步骤三，根据第一夹角和第二夹角，分别确定显示屏显示的内容的旋转角度以及旋转方向，具体包括：
若第一夹角不等于0°以及大于-90°且小于90°，则将第一夹角的绝对值确定为显示屏显示的内容以第二坐标轴为中心的旋转角度，其中，第一夹角大于-90°且小于0°的旋转方向与第一夹角大于0°且小于90°的旋转方向相反；
若第二夹角小于90°或大于90°，则将第二夹角与90°的差值的绝对值确 定为显示屏显示的内容以第一坐标轴为中心的旋转角度，其中，第二夹角小于90°的旋转方向与第二夹角大于90°的旋转方向相反；具体的，当第二夹角大于0°且小于90°时，旋转角度为90°-β，当第二夹角大于90°且小于180°时，旋转角度为β-90°。
其中，针对确定在第一坐标轴和第二坐标轴上的显示尺寸缩小系数的情况，具体的，上述步骤五，根据第一夹角和第二夹角，分别确定显示屏显示的内容的显示尺寸的缩小系数，具体包括：
若第一夹角不等于0°以及大于-90°且小于90°，则将第一夹角的余弦值确定为显示屏显示的内容的显示尺寸在第一坐标轴上的缩小系数；
若第二夹角小于90°或大于90°，则将第二夹角的正弦值确定为显示屏显示的内容的显示尺寸在第二坐标轴上的缩小系数；具体的，当第二夹角大于0°且小于90°时，缩小系数为cos(90°-β)＝sinβ，当第二夹角大于90°且小于180°时，缩小系数为cos(β-90°)＝sinβ。
具体的，基于如下旋转方向的定义，对显示屏显示的内容的旋转调整和缩小调整进行详细说明：
以第二坐标轴Y轴为中心，显示屏左端沿第三坐标轴Z轴方向的旋转为水平正旋转，显示屏左端沿第三坐标轴-Z轴方向的旋转为水平负旋转；
以第一坐标轴X轴为中心，显示屏上端沿第三坐标轴Z轴方向的旋转为垂直正旋转，显示屏上端沿第三坐标轴-Z轴方向的旋转为垂直负旋转。
在一个实施例中，若第一角度α不为零，即显示屏在第一坐标轴方向上发生偏移，则可通过以下步骤A1-A3来调整显示屏显示的内容：
步骤A1，确定显示屏在第一坐标轴方向上的第一角度，其中，该第一角度表征显示屏在第一坐标轴上的偏移方向和偏移幅度，具体的，若第一角度α大于-90度且小于0度，则显示屏左端远离人眼，若第一角度α大于0度且小于90度，则显示屏右端远离人眼。
该步骤中，可通过眼球追踪技术来确定显示屏在第一坐标轴方向上的第 一角度。具体的，当追踪到人眼的眼球向左移动时，则可确定显示屏位于人眼的左侧，即显示屏在第一坐标轴上的偏移方向为向左偏移(显示屏左端远离人眼)；当追踪到人眼的眼球向右移动时，则可确定显示屏位于人眼的右侧，即显示屏在第一坐标轴上的偏移方向为向右偏移(显示屏右端远离人眼)。
步骤A2，根据确定出的第一角度，确定显示屏显示的内容在第一坐标轴上的第一旋转方向、第一旋转角度及第一尺寸缩小倍数(即第一缩小系数)。
步骤A3，按照第一旋转方向及第一旋转角度以第二坐标轴为中心旋转显示屏显示的内容，以及，按照第一尺寸缩小倍数缩小显示屏显示的内容的宽度(即缩小显示屏短边上的显示尺寸)。
根据显示屏在第一坐标轴上的偏移方向的不同，可分为如下两种情况。
情况一、当-90°＜α＜0°时，即显示屏在第一坐标轴上的偏移方向为向左偏移，此时，显示屏显示的内容的左侧比显示屏显示的内容的右侧相对于人眼而言距离更远，因此可确定显示屏显示的内容的第一旋转方向为：显示屏显示的内容的左侧在第一坐标轴方向上向外旋转、同时右侧在第一坐标轴方向上向内旋转(即水平正旋转)，第一旋转角度即为第一角度α。
情况二、当0°＜α＜90°时，即显示屏在第一坐标轴上的偏移方向为向右偏移，此时，显示屏显示的内容的右侧比显示屏显示的内容的左侧相对于人眼而言距离更远，因此可确定显示屏显示的内容的第一旋转方向为：显示屏显示的内容的右侧在第一坐标轴方向上向外旋转、同时左侧在第一坐标轴方向上向内旋转(即水平负旋转)，第一旋转角度即为第一角度α。
此外，由于显示屏显示的内容旋转的同时显示屏并不旋转，导致内容旋转后的尺寸受显示屏的影响发生尺寸上的变化，因此需相应缩小显示屏显示的内容的尺寸。为使内容能够完整显示，需将显示屏显示的内容的宽度缩小第一尺寸缩小倍数cosα。
其中，第一尺寸缩小倍数的确定可由图5所示得出。在图5中，显示屏显示的内容501按照第一旋转方向及第一旋转角度α旋转后成为显示屏显示 的内容502，x为内容501的原始宽度，y为内容502的旋转后宽度。由图5可看出，
Figure PCTCN2019082043-appb-000001
因此，y＝x*cosα。即，内容502的旋转后宽度为内容501的原始宽度的cosα倍。
需要说明的是，图5示出的仅是上述情况一的旋转情况，即显示屏在第一坐标轴上的偏移方向为向左偏移时对内容的旋转情况，对于情况二的旋转情况，第一尺寸缩小倍数的确定方式也与此类似，也为cosα，在此不一一赘述。
本实施例中，当显示屏在第一坐标轴方向上发生偏移时，能够通过旋转内容及调整内容的宽度，使得显示屏相对于人眼视线发生偏移时仍能为用户呈现出最佳角度的内容，从而提高用户浏览显示屏显示的内容的体验度。
在一个实施例中，若第二角度β不为零，即显示屏在第二坐标轴方向上发生偏移，则可通过以下步骤B1-B3来调整显示屏显示的内容：
步骤B1，确定显示屏在第二坐标轴方向上的第二角度，其中，该第二角度表征显示屏在第二坐标轴上的偏移方向和偏移幅度，具体的，若第二角度β小于90度，则显示屏下端远离人眼，若第二角度β大于90度，则显示屏上端远离人眼。
该步骤中，可通过移动终端内设的陀螺仪来确定第二角度的值。具体的，若第二角度为90度，则可确定显示屏在第二坐标轴方向上未发生倾斜；若第二角度大于90度，则可确定显示屏的上端远离人眼，即显示屏在第二坐标轴上的偏移方向为：显示屏的上端在第二坐标轴方向上向内偏移(即远离人眼)、同时下端在第二坐标轴方向上向外偏移(即靠近人眼)；若第二角度小于90度，则可确定显示屏的下端远离人眼，即显示屏在第二坐标轴上的偏移方向为：显示屏的上端在第二坐标轴方向上向外偏移(即靠近人眼)、同时下端在第二坐标轴方向上向内偏移(即远离人眼)。
步骤B2，根据确定出的第二角度，确定显示屏显示的内容在第二坐标轴上的第二旋转方向、第二旋转角度及第二尺寸缩小倍数(即第二缩小系数)。
步骤B3，按照第二旋转方向及第二旋转角度以第一坐标轴为中心旋转显示屏显示的内容，以及，按照第二尺寸缩小倍数缩小该内容的长度(即缩小显示屏长边上的显示尺寸)。
根据显示屏在第二坐标轴上的偏移方向的不同，可分为如下两种情况。
情况一、当β＞90°时，即显示屏在第二坐标轴上的偏移方向为：显示屏的上端在第二坐标轴方向上向内偏移、同时下端在第二坐标轴方向上向外偏移。此时，显示屏显示的内容的上端比显示屏显示的内容的下端相对于人眼而言距离更远，因此可确定显示屏显示的内容的第二旋转方向为：显示屏显示的内容的上端在第二坐标轴方向上向外旋转(即靠近人眼)、同时下端在第二坐标轴方向上向内旋转(即远离人眼)，即垂直正旋转，第二旋转角度即为β-90°。
此外，由于显示屏显示的内容旋转的同时显示屏并不旋转，导致内容旋转后的尺寸受显示屏的影响发生尺寸上的变化，因此需相应缩小显示屏显示的内容的尺寸。为使内容能够完全呈现在显示屏中，需将内容的长度缩小第二尺寸缩小倍数cos(β-90°)。
其中，第二旋转角度和第二尺寸缩小倍数的确定可由图6所示得出。图6所示为显示屏显示的内容600的侧面图，此时人眼位于右侧(图中未示出)，显示屏显示的内容600的上端远离人眼，下端靠近人眼，Z轴与重力方向之间的夹角为β，显然，β大于90度。为使内容能够被调整至人眼视线的最佳角度，则需将内容600旋转至与重力方向重合的位置。由图6所示的角度关系可计算出，第二旋转角度为β-90°。假设内容600的长度为m，旋转至与重力方向重合的位置后的长度为n，则由图6可看出：
Figure PCTCN2019082043-appb-000002
因此：n＝m*cos(β-90°)。即，内容600旋转后的长度为旋转前的长度的cos(β-90°)倍。
情况二、当β＜90°时，即显示屏在第二坐标轴上的偏移方向为：显示屏的上端在第二坐标轴方向上向外偏移、同时下端在第二坐标轴方向上向内偏 移。此时，显示屏显示的内容的上端比显示屏显示的内容的下端相对于人眼而言距离更近，因此可确定显示屏显示的内容的第二旋转方向为：显示屏显示的内容的上端在第二坐标轴方向上向内旋转(即远离人眼)、同时下端在第二坐标轴方向上向外旋转(即靠近人眼)，即垂直负旋转，第二旋转角度即为90°-β。
此外，由于显示屏显示的内容旋转的同时显示屏并不旋转，导致内容旋转后的尺寸受显示屏的影响发生尺寸上的变化，因此需相应缩小内容的尺寸。为使内容能够完全呈现在显示屏中，需将内容的长度缩小第二尺寸缩小倍数cos(90°-β)。
其中，第二旋转角度和第二尺寸缩小倍数的确定可由图7所示得出。图7所示为显示屏显示的内容700的侧面图，此时人眼位于右侧(图中未示出)，显示屏显示的内容700的上端靠近人眼，下端远离人眼，Z轴与重力方向之间的夹角为β，显然，β小于90度。为使内容能够被调整至人眼视线的最佳角度，则需将内容700旋转至与重力方向重合的位置。由图7所示的角度关系可计算出，第二旋转角度为90°-β。假设内容700的长度为m，旋转至与重力方向重合的位置后的长度为n，则由图7可看出：
Figure PCTCN2019082043-appb-000003
因此：n＝m*cos(90°-β)。即，内容700旋转后的长度为旋转前的长度的cos(90°-β)倍。
本实施例中，当显示屏在第二坐标轴方向上发生偏移时，能够通过旋转内容及调整内容的长度(高度)，使得显示屏相对于人眼视线发生偏移时仍能为用户呈现出最佳角度的内容，从而提高用户浏览显示屏显示的内容的体验度。
以下列举几种具体场景的实施例来说明如何调整显示屏显示的内容。
场景一、显示屏在第一坐标轴方向上向左偏移，即α不为零，-90°＜α＜0°。同时，显示屏在第二坐标轴方向上也可有所偏移，具体如下：

(3)显示屏在第二坐标轴方向上未发生偏移，此时Z轴与重力方向之间的夹角β等于90度。针对此场景，应将显示屏显示的内容的右侧以第二坐标轴为中心在第一坐标轴方向上向外旋转角度α、左侧以第二坐标轴为中心在第一坐标轴方向上向内旋转角度α，并将内容的宽度缩小cosα倍。同时，在第二坐标轴方向上无需调整显示屏显示的内容。
场景三、显示屏在第一坐标轴方向未发生偏移，即α为零。同时，显示屏在第二坐标轴方向上也可有所偏移，具体如下：
