其中，第一运动速度可以是导航目标相对地面的速度，也可以是导航目标相对除地面之外的其他参照物的速度。
在一些实施例中，第一设备可以通过速度传感器和加速度传感器等用于检测运动速度的传感器，获取第一运动速度。在另一些实施例中，第一设备可以通过卫星或者基站来检测第一运动速度。当然，在实际应用中，第一设备也可以通过其他方式来获取第一运动速度，本申请实施例不对第一设备获取第一运动速度的方式进行限定。
需要说明的是，第一设备可以直接调用硬件层的传感器等硬件组件来获取第一运 动速度，也可以在软件层的某个应用程序获取第一运动速度。例如，第一设备中包括某地图应用，该地图应用包括用于提供当前运动速度的运动速度接口，因此，第一设备通过调用该运动速度接口来获取第一运动速度。
S602，第一设备获取与导航目标对应的引导速度。
在一些实施例中，引导速度的参照物和第一运动速度的参照物可以相同。
在一些实施例中，第一设备可以获取导航目标对应的运动环境信息，基于该运动环境信息确定引导速度。其中，运动环境信息用于指示导航目标所在的环境。在一些实施例中，运动环境信息可以包括位置信息、天气信息和障碍物信息中的至少一个。
位置信息可以用于指示导航目标所在的位置。在一些实施例中，位置信息可以包括导航目标所在的位置坐标，如经度和维度等。在一些实施例中，位置信息可以包括导航目标所在的道路标识、路段标识和路段类型中的至少一个，其中，路段类型可以由交通部门等专业人员确定，比如，路段类型可以包括直行车道、左转车道、右转车道、主干道、次干道、辅道、定向匝道、半定向匝道、一般匝道、集散车道和高速车道等等。在一些实施例中，位置信息可以包括离地高度。当然，在实际应用中，位置信息也可以包括其他能够指示导航目标所在位置的信息。
在一些实施例中，第一设备可以通过卫星定位或者基站定位等方式确定该位置信息。或者，第一设备可以获取导航目标周围的图像，并从图像中获取地名、路牌、道路标识、路段标识和路段类型等位置信息。
天气信息可以用于指示导航目标所在地区的天气。在一些实施例中，天气信息可以包括雾霾、雨、雪和能见度等信息。当然，在实际应用中，天气信息也可以包括其他能够指示天气的信息。
在一些实施例中，第一设备可以基于所获取的位置信息，从网络中获取与该位置信息对应的天气信息。或者，第一设备可以获取导航目标周围的图像，并从图像中识别相应的天气信息。
障碍物信息可以用于指示导航目标第一预设范围内的障碍物的位置和状态等信息，其中，障碍物可以为阻碍导航目标通行的物体，如墙体、护栏、行人和载具等等。在一些实施例中，障碍物信息可以包括障碍物的类型、障碍物的方位、该障碍物距离导航目标的距离和该障碍物的移动速度中的一个或多个。当然，在实际应用中，障碍物信息也可以包括其他能够指示障碍物的位置或状态的信息。
其中，第一预设范围可以由第一设备事先确定，本申请实施例不对第一预设范围的大小进行限定。
在一些实施例中，第一设备可以通过雷达、距离传感器等传感器，检测导航目标周围是否包括障碍物，如果是可以进一步确定该障碍物的类型、该障碍物的方位、该障碍物距离导航目标的距离和该障碍物的移动速度等信息。或者，第一设备可以获取导航目标周围的图像，从图像中识别障碍物信息。
需要说明的是，在实际应用中，第一设备也可以通过其他方式来获取运动环境信息，本申请实施例不对第一设备获取该运动环境信息的方式进行限定。
当第一设备获取到运动环境信息时，可以基于运动环境信息确定与导航目标所在的环境相匹配的引导速度。
在一些实施例中，第一设备中可以存储有多种运动环境信息以及与各种运动环境信息对应的引导速度，相应的，第一设备可以基于所确定的运动环境信息，获取存储的与该运动环境信息所对应的引导速度。
需要说明的是，第一设备可以事先确定多种运动环境信息中各中运动环境信息对应的引导速度并进行存储。在一些实施例中，可以由相关技术人员，事先根据各种运动环境信息确定相对应的引导速度，并向第一设备提交各种运动环境信息以及对应的引导速度并进行存储。
例如，一种位置信息与引导速度之间的对应关系可以如下表1所示，其中，表1的前两列可以为导航目标所在的位置信息，最后一列为相应位置信息对应的引导速度。
表1
表1可以是由道路交通规划管理人员针对交叉口类型的汽车道设置的多种引导速度，其中，V1可以是事先设定的数值。以第2行为例，若导航目标当前所在的位置为位于进口道直行车道的平面交叉口，则对应的引导速度可以为0.7*V1。又以第6行为例，若导航目标当前所在的位置为位于定向匝道、半定向匝道或辅道的立体交叉口，则对应的引导速度可以为0.6*V1～0.7*V1之间。
又例如，道路交通规划管理人员事先规定了，在雨雪天气中，当能见度低于200米时，最高速度为60千米/小时；当能见度低于100米时，最高速度为40千米/小时；当能见度低于50米时，最高速度为20千米/小时。那么第一设备的开发人员可以基于道路交通规划管理人员所设置的最高速度，分别设置与雨雪天气中三种能见度对应的引导速度，使得该引导速度小于或等于该引导速度对应的能见度下的最高速度。
又例如，当障碍物信息指示导航目标前方出现障碍物，且障碍物在导航目标的行驶方向的速度为0时，引导速度可以为0。
在一些实施例中，导航目标所行使的道路、轨道或航线上，可以设置有速度引导标志，诸如红绿灯和限速牌等，该速度引导标志可以用于指示与该速度引导标志所在位置对应的引导速度，因此当导航目标行驶到该位置时，第一设备或导航目标可以获取导航目标周围的图像，第一设备可以从该图像识别该速度引导标志，进而基于该速 度引导标志确定与该位置的位置信息对应的引导速度。其中，速度引导标志可以是由相关技术人员事先根据该速度引导标志所在位置确定的。
在一些实施例中，第一设备可以将运动环境信息输入至存储的第一机器学习模型，并得到第一机器学习模型输出的引导速度。其中，第一机器学习模型可以事先基于第一样本集合训练得到，第一样本集合包括多个样本，各样本中包括运动环境信息以及标记的引导速度。
在一些实施例中，第一设备可以接收用户提交的引导速度。比如，用户在驾驶的过程中，因为期望及时到达目的地而主动设置的引导速度，或者，用户在跑步机跑步时主动设置的期望的引导速度。
在一些实施例中，第一设备可以获取用户提交的运动路线和运动时限，基于该运动路线和该运动时限，确定引导速度。
在一些实施例中，第一设备还可以确定第一速度范围，引导速度可以第一速度范围中包括的数值，其中，第一速度范围可以为指示导航目标达到的较佳运动速度。例如，在高速车道中，道路交通规划管理人员设置的最低时速为80千米/小时，最高时速为120千米/小时，在忽略天气信息和障碍物信息的情况下，第一设备所确定的引导速度可以为100千米/小时，第一速度范围可以为80千米/小时-120千米/小时之间。又例如，第一设备为车载导航设备，第一设备在车辆前方检测到障碍物，为避免撞到障碍物并考虑用户的舒适性，第一设备需要降低至时速(即引导速度)40千米/小时，当然实际上低于40千米/小时也不会撞到障碍物，因此，第一速度范围可以为40千米/小时或者低于40千米/小时。
需要说明的是，第一设备确定第一速度范围的方式，可以与确定引导速度的方式相同或相似。
还需要说明的是，第一设备也可以通过其他方式确定第一速度和/或第一速度范围。
还需要说明的是，在实际应用中，第一设备可以先后执行S601和S602，也可以同时执行S601和S602，本申请实施例不对第一设备执行S601和S602的顺序进行限定。
S603，第一设备基于第一运动速度和引导速度，显示运动的第一视觉元素，其中，第一视觉元素用于指示导航目标加速或减速，第一视觉元素的第二运动速度与第一运动速度和引导速度的差值的绝对值成正相关。
视觉元素可以作为传达信息的工具和媒介，视觉元素可以包括如图形、文字、形状和形体等信息元素，也可以包括如点、线、面、色彩和空间等形式元素。例如，视觉元素可以包括箭头或者条纹。
需要说明的是，运动的第一视觉元素可以理解为第一视觉元素在导航界面中的位置会发生改变。运动的第一视觉元素能够更加容易吸引用户的注意力，从而及时引导用户加速或减速，提高导航效果。
第二运动速度与第一行驶速度和引导速度的差值的绝对值成正相关，也即是，若导航目标的第一运动速度与引导速度的差值的绝对值越大，第一视觉元素的第二运动速度也越大，从而使得用户能够越加直观地感受到第一运动速度与引导速度之间的差值的绝对值大小，进而采取相应的措施以更快地增大或减小导航目标的运动速度。在 一些实施例中，第一视觉元素的第一运动速度可以等于第二运动速度与引导速度的差值的绝对值。
在一些实施例中，第一视觉元素的第二运动速度的参照物可以与第一运动速度和引导速度的参照物相同。
在一些实施例中，若第一运动速度小于引导速度，则显示沿第一方向运动的第一视觉元素，以指示导航目标加速；若第一运动速度大于引导速度，则显示沿第二方向运动的第一视觉元素，以指示导航目标减速。
其中，第一方向和第二方向可以由电子设备事先确定，且第一方向和第二方向可以不同。在一些实施例中，第一方向可以和第二方向平行且相反。在一些实施例中，第一方向可以是由靠近用户的位置指向远离用户的位置，比如第一方向可以为远离导航界面的底部的方向，以使得驾驶员更直观地产生第一视觉元素远离载具的感觉，从而使驾驶员更容易地联想到加速追赶，减少驾驶员的反应时间，提高辅助驾驶的可靠性；第二方向可以为为由远离用户的位置指向靠近用户的位置，比如第一方向可以为靠近导航界面的底部的方向，以使得驾驶员更直观地产生第一视觉元素靠近载具的感觉，从而使驾驶员更容易地来联想到减速避让，减少驾驶员的反应时间。当然，在实际应用中，第一方向和第二方向也可以为其他方向。
例如，导航界面如图7和图8所示，第一视觉元素包括箭头700。第一方向为由导航界面的底部指向导航界面的中心位置的方向，第二方向为由导航界面的中心位置指向导航界面的底部的方向。若显示沿第一方向运动的箭头700，则可以依次显示包括图7和图8的第一图像集合，第一图像集合中的各帧图像中都可以包括箭头700，且对于每个箭头700，该箭头700在较早显示的图像中的位置可以比在较晚显示的图像中位置更靠近导航界面的底部，从而使得当依次显示第一图像集合时，箭头700远离导航界面的底部。比如图7与图8相比，虚线框中包括的两个箭头700更靠近导航界面的底部，那么当先显示图7再显示图8时，可以产生这两个箭头700远离导航界面的底部的动画效果。相反的，若显示沿第二方向运动的箭头700，则可以依次显示包括图8和图7的第二图像集合，第二图像集合中的各帧图像中都可以包括箭头700，且对于每个箭头700，该箭头700在较早显示的图像中的位置可以比在较晚显示的图像中位置更远离导航界面的底部，从而使得当依次显示第二图像集合时，箭头700靠近导航界面的底部。比如图7与图8相比，虚线框中包括的两个箭头700更靠近导航界面的底部，那么当先显示图8再显示图7时，可以产生这两个箭头700朝向导航界面的底部运动的动画效果。
又例如，如图9和图10所示，第一视觉元素包括光波900(即图9和图10中虚线框中的深色条纹)。第一方向为远离导航界面的底部的方向，第二方向为靠近导航界面的底部的方向。若显示沿第一方向运动的光波900，则可以依次显示包括图9和图10的第三图像集合，第三图像集合中的各帧图像中都可以包括光波900，且对于每个光波900，该光波900在较早显示的图像中的位置可以比在较晚显示的图像中位置更靠近导航界面的底部，从而使得当依次显示第三图像集合时，光波900远离导航界面的底部。比如图9与图10相比，虚线框中包括的光波900更靠近导航界面的底部，那么当先显示图9再显示图10时，可以产生光波900远离导航界面的底部的动画效果。 相反的，若显示沿第二方向运动的光波900，则可以依次显示包括图10和图9的第四图像集合，第四图像集合中的各帧图像中都可以包括光波900，且对于每个光波900，该光波900在较早显示的图像中的位置可以比在较晚显示的图像中位置更远离导航界面的底部，从而使得当依次显示第四图像集合时，光波900靠近导航界面的底部。比如图9与图10相比，虚线框中包括的光波900更靠近导航界面的底部，那么当先显示图10再显示图9时，可以产生光波900朝向导航界面的底部运动的动画效果。
在一些实施例中，若显示器为HUD或者AR眼镜，第一设备可以从摄像头拍摄到的画面中识别该画面包括的特定物体，通过视觉识别算法确定该特定物体在该画面中的二维坐标，通过事先标定的摄像头参数(比如摄像头的焦距、畸变参数、第一位移矩阵和旋转矩阵等)，将该特定物体的二维坐标转换为三维坐标，然后基于该特定物体的三维坐标确定第一视觉元素的三维坐标，基于确定的第一视觉元素的三维坐标将第一视觉元素绘制到该画面中。比如，在用户驾驶车辆的过程中，第一设备为车辆的车载导航设备，那么第一设备可以通过摄像头拍摄车辆前方的画面，然后通过机器视觉识别该画面中的车道线，确定车道线在该画面中的二维坐标，并给予摄像头的参数将二维坐标转换为三维坐标，基于车道线的三维坐标确定第一视觉元素的三维坐标，基于第一视觉元素的三维坐标将第一视觉元素绘制到该画面中的车道中。在一些实施例中，第一设备可以通过第一设备中的操作系统所提供的动画接口，绘制第一视觉元素运动的效果。其中，第一设备可以通过增大第一视觉元素的z轴(即与车道平行的方向的坐标轴)坐标，实现第一视觉元素远离用户的动画效果，通过减小第一视觉元素的z轴坐标，实现第一视觉元素靠近与用户的视觉效果；或者，第一设备可以通过预设的第二位移矩阵，对第一视觉元素进行矩形平移运算，从而实现第一视觉元素移动的动画效果。
需要说明的是，在上述图7-图9中，第一设备所展示的导航界面为平视视角的导航界面，且为了更加直观真实地展示第一视觉元素，第一视觉元素也是以平视视角展示在与该导航界面中特定物体相对应的位置(如车道中)，但可以理解的是，在实际应用中，第一视觉元素也可以是通过其他视角展示的，也可以是展示在导航界面中的其他位置。例如，如图11所示，导航界面为俯视视角的导航界面，光波900也是以俯视视角显示在车道中。又例如，如图12所示，导航界面仍为平视视角的导航界面，但光波900是显示在该导航界面的左侧，且不与该导航界面中包括的任一物体的位置关联。
在一些实施例中，第一设备可以在检测到第一运动速度和引导速度不一致时，显示运动的第一视觉元素，在检测到第一运动速度与引导速度一致时，停止显示运动的第一视觉元素，通过这种更为精准的速度引导方式，可以使得用户尽可能的及时调整自身或者载具的运动速度，使其与引导速度保持一致，从而能够提高导航的准确性。
其中，第一设备在检测到第一运动速度与引导速度一致时，停止显示运动的第一视觉元素，可以包括：第一设备在检测到第一运动速度与引导速度一致时，立即停止显示运动的第一视觉元素；或者，第一设备在检测到第一运动速度与引导速度一致，且第一运动速度与引导速度保持一致的时长大于预设的第二时长阈值时，再停止显示运动的第一视觉元素，从而增加显示运动的第一视觉元素的时长，以更长时间引导用户调整自身或者载具的运动速度，减少该运动速度与引导速度的偏差。
需要说明的是，第二时长阈值可以由相关技术人员事先设置，也可以由用户设置，本申请实施例不对设置第二时长阈值的方式以及第二时长阈值的大小进行限定。
在一些实施例中，第一设备可以检测到第一运动速度不处于第一速度范围时，显示运动的第一视觉元素，而在检测到第一运动速度处于第一速度范围时，停止显示运动的第一视觉元素，从而引导用户调整自身或者载具的运动速度至靠近第一速度范围即可，这种速度引导方式便于用户更加自由灵活地控制自身或载具的运动速度，提高了导航的灵活性和用户体验。
在一些实施例中，第一设备可以在检测到第一运动速度不处于第一速度范围时，显示运动的第一视觉元素，在检测到第一运动速度与引导速度一致时，停止显示运动的第一视觉元素。
其中，第一设备在检测到第一运动速度处于第一速度范围时，停止显示运动的第一视觉元素，可以包括：第一设备在检测到第一运动速度处于第一速度范围时，立即停止显示运动的第一视觉元素，从而减少显示运动的第一视觉元素的时长，便于用户更加自由灵活地控制自身或载具的运动速度；或者，第一设备在检测到第一运动速度处于第一速度范围，且第一运动速度处于第一速度范围的时长大于预设的第一时长阈值时，再停止显示运动的第一视觉元素，从而增加显示运动的第一视觉元素的时长，以更长时间引导用户调整自身或者载具的运动速度，减少该运动速度与引导速度或者第一速度范围的偏差。
需要说明的是，第一时长阈值可以由相关技术人员事先设置，也可以由用户设置，本申请实施例不对设置第一时长阈值的方式以及第一时长阈值的大小进行限定。
在一些实施例中，第一设备还可以显示运动的第二视觉元素，且若第一视觉元素用于指示导航目标加速，则第二视觉元素可以用于指示导航目标减速，若第一视觉元素用于指示导航目标减速，则第二视觉元素可以用于指示导航目标加速，第二视觉元素的第三运动速度可以与第一运动速度和引导速度的差值的绝对值成正相关。其中，当第一视觉元素用于指示导航目标加速，第二视觉元素用于指示导航目标减速时，若第一运动速度小于引导速度，则第一设备显示沿第一方向运动的第一视觉元素，若第一运动速度大于引导速度，则第一设备显示沿第二方向运动的第二视觉元素；当第一视觉元素用于指示导航目标减速，第二视觉元素用于指示导航目标加速时，若第一运动速度小于引导速度，则第一设备显示沿第一方向运动的第二视觉元素，若第一运动速度大于引导速度，则第一设备显示沿第二方向运动的第一视觉元素。也即是，可以通过显示不同风格的第一视觉元素和第二视觉元素，能够更加直观地分别指示导航设备加速或减速，使得用户更加容易根据第一视觉元素或第二视觉元素做出不同的反应，进一步提高导航的准确性和用户体验。
在一些实施例中，第一设备可以在第一设备本端显示第一视觉元素和第二视觉元素等导航信息，比如第一设备为如图3所示的导航场景中的电子设备100，电子设备100即可以在电子设备100本端显示该导航信息。在另一些实施例中，第一设备也可以通过第三设备显示该导航信息，比如第一设备为如图5所示的导航场景中的手机510，第三设备为如图5所示的导航场景中的AR眼镜520，那么手机510既可以在手机510本端显示该导航信息，当然也可以通过AR眼镜520显示该导航信息。
在一些实施例中，上述停止显示运动的第一视觉元素，可以包括显示静止的第一视觉元素，或者隐藏第一视觉元素；相似的，停止显示运动的第二视觉元素，可以包括显示静止的第二视觉元素，或者隐藏第二视觉元素。
在本申请实施例中，导航目标为第一设备。第一设备可以获取导航目标的第一运动速度以及与导航目标对应的引导速度，并基于第一运动速度和引导速度显示运动的第一视觉元素。由于运动的第一视觉元素更容易吸引用户的注意力，从而可以通过第一视觉元素指示导航目标加速或减速，且第一视觉元素的第二运动速度与第一导航目标的第一运动速度和引导速度的差值的绝对值成正相关，能够更加直观地指示导航目标加速或减速的程度，提高了导航效果。
以下结合如图3所示的实地驾驶下的导航场景，举例说明通过本申请所提供的导航方法引导用户控制车辆加速和减速。
用户驾驶车辆在右侧慢车道打火起步，车辆导航设备该右侧慢车道确定相应的引导速度为40千米/小时，且车辆当前的第一运动速度为0，因此，通过HUD在前挡风玻璃上显示向前滚动的箭头，且箭头的运动速度为40千米/小时(即引导速度与第一运动的差值的绝对值)。当用户看到向前滚动的箭头时，可以确定当前的第一运动速度小于引导速度，因此踩油门加速，使得车辆的运动速度逐渐接近引导速度，且随着车辆的运动速度与引导速度的差值的绝对值不断减小，箭头向前滚动的速度也逐渐降低，直至车辆的运动速度与引导速度相同，箭头停止运动或者消失。
接着，用户驾驶车辆从右侧慢车道变到至左侧快车道，车辆导航设备基于所变换的快车道以及天气信息，确定引导速度为80千米/小时，而当前的第一运动速度为40千米/小时。由于当前的第一运动速度小于引导速度，因此通过HUD在前挡风玻璃上显示向前滚动的箭头700，且箭头700的运动速度为40千米/小时(即引导速度与第一运动的差值的绝对值)，如图13所示。当用户看到向前滚动的箭头700时，可以确定当前的第一运动速度小于引导速度，因此踩油门加速，使得车辆的运动速度逐渐接近引导速度，且随着车辆的运动速度与引导速度的差值的绝对值不断减小，箭头700向前滚动的速度也逐渐降低，直至车辆的运动速度与引导速度相同，箭头700停止运动或者消失。
之后，用户驾驶车辆靠近十字路口，当前的第一运动速度为60千米/小时，车辆导航设备检测到当前该十字路口为红灯亮，因此引导速度为0。由于引导速度小于第一运动速度，因此通过HUD在前挡风玻璃上向后滚动的箭头700，且箭头700向后滚动的速度为60千米/小时(即引导速度与第一运动的差值的绝对值)，如图14所示。在一些实施例中，车辆导航设备可以基于第一运动速度和预设的感知反应时长确定第一距离，并在检测到车辆距离路口的距离为第一距离时，开始显示箭头700。在一些的实施例中，第一距离可以为第一运动速度和预设的感知反应时长的乘积。其中，感知反应时长可以为驾驶员反应所需要的时间。当用户看到向后滚动的箭头700时，可以确定当前的第一运动速度大于引导速度，因此踩下刹车制动，使得车辆的运动速度逐渐降低，且随着车辆的运动速度与引导速度的差值的绝对值不断减小，箭头700向后滚动的速度也逐渐降低，直至车辆停止，箭头700停止运动或者消失。
当车辆导航设备检测到当前该十字路口为黄灯亮时，根据车辆所处的车道确定引 导速度为60千米/小时，而车辆当前的第一运动速度为0，因此通过HUD在前挡风玻璃上向前滚动的箭头，且箭头向前滚动的速度为60千米/小时(即引导速度与第一运动的差值的绝对值)。当用户看到向前滚动的箭头时，可以确定当前的第一运动速度小于引导速度，因此踩下油门加速，使得车辆的运动速度逐渐增大，且随着车辆的运动速度与引导速度的差值的绝对值不断减小，箭头向前滚动的速度也逐渐降低，直至车辆的运动速度达到60千米/小时，箭头停止运动或者消失。
接着，车辆仍以60千米/小时的速度(即第一运动速度为60千米/小时)行驶，在行驶的过程中检测前方有其他车辆，且该车辆的运动速度为40千米/小时，车载导航设备基于该车辆当前的运动速度、当前与该车辆之间的车距以及预设的感知反应时长，确定引导速度。在一些实施例中，车载导航设备可以将该车辆当前的运动速度，减去该车距和该感知反应时长的乘积所得到的差值的绝对值，确定为引导速度。假如确定的引导速度为30千米/小时，由于引导速度小于第一运动速度，因此通过HUD在前挡风玻璃上向后滚动的箭头，且箭头向后滚动的速度为30千米/小时。在一些实施例中，车载导航设备也可以在检测到车辆中的前方碰撞预警系统(forward collision warning，FCW)发出预警信号时(比如在预测碰撞前的2.7秒)，在前挡风玻璃上显示向后滚动的箭头。当用户看到向后滚动的箭头时，可以确定当前的第一运动速度大于引导速度，因此踩下刹车制动，使得车辆的运动速度逐渐降低，且随着车辆的运动速度与引导速度的差值的绝对值不断减小，箭头向后滚动的速度也逐渐降低，直至按照引导速度行驶，箭头停止运动或者消失。
请参照图15，为本申请实施例所提供的一种导航方法的流程图。其中，第一设备可以为如图3或图4所示的导航场景中的电子设备100，第二设备可以为如图3所示的导航场景中的第一载具310或者如图4所示的导航场景中的第二载具320。在本申请实施例中，第一设备为进行导航的设备，第二设备为导航目标(即被导航的设备)，也即是，第一设备对第二设备进行导航。需要说明的是，该方法并不以图15以及以下所述的具体顺序为限制，应当理解，在其它实施例中，该方法其中部分步骤的顺序可以根据实际需要相互交换，或者其中的部分步骤也可以省略或删除。该方法包括如下步骤：
S1501，第一设备获取导航目标的第一运动速度，其中，导航目标为与第一设备通过网络连接的第二设备。
其中，第二设备可以获取第二设备的第一运动速度，并向第一设备发送第一运动速度。且需要说明的是，第二设备获取第二设备的第一运动速度的方式，可以与前述中第一设备获取第一设备的第一运动速度的方式相同或相似，此处不再一一赘述。
S1502，第一设备获取与导航目标对应的引导速度。
在一些实施例中，第二设备可以获取导航目标对应的运动环境信息，并向第一设备发送该运动环境信息，相应的，第一设备可以接收该运动环境信息并基于该运动环境信息确定引导速度。或者，在一些实施例中，第二设备可以获取该运动信息并基于该运动信息确定引导速度，向第一设备发送该引导速度，第一设备可以接收二设备发送的该引导速度。
在一些实施例中，第一设备可以接收用户提交的引导速度。
在一些实施例中，第一设备可以获取用户提交的运动路线和运动时限，基于该运动路线和该运动时限，确定引导速度。
在一些实施例中，第一设备还可以确定第一速度范围，引导速度可以为处于第一速度范围中的数值。
需要说明的是，第一设备也可以通过其他方式确定第一速度和/或第一速度范围。
还需要说明的是，在实际应用中，第一设备可以先后执行S1501和S1502，也可以同时执行S1501和S1502，本申请实施例不对第一设备执行S1501和S1502的顺序进行限定。

在一些实施例中，第一设备可以在第一设备本端显示第一视觉元素和第二视觉元素等导航信息。在另一些实施例中，第一设备也可以通过第二设备或第三设备显示该导航信息。比如第一设备为如图3或图4所示的导航场景中的电子设备100，电子设备100既可以在电子设备100本端显示该导航信息，也可以通过AR眼镜显示该导航信息。
在本申请实施例中，导航目标为第二设备。第一设备可以获取第二设备的第一运动速度以及与第二设备对应的引导速度，并基于第一运动速度和引导速度在第一设备中显示运动的第一视觉元素。由于运动的第一视觉元素更容易吸引用户的注意力，从而可以通过第一视觉元素指示第二设备加速或减速，且第一视觉元素的第二运动速度与第一第二设备的第一运动速度和引导速度的差值成正相关，能够更加直观地指示第二设备加速或减速的程度，提高了导航效果。
