可选地，微型投影器10包括显示屏12及透镜13，可穿戴设备通过可穿戴设备的控制器20根据该补偿量控制显示屏12所显示的图像移动。
可选地，可穿戴设备的显示屏12所显示的图像的移动方向与可穿戴设备的抖动方向相同。
举例来说，如图4所示，图4a是可穿戴设备处于未抖动状态的示意图(为方便表述将模型进行简化，其中显示屏12、透镜13及地面均位于同一高度，光源11发出的光线穿过显示屏12及透镜13直接照射到前方的地面上。但实际上，地面应位于显示屏12及透镜13下方，显示屏12及透镜13应为倾斜向下朝向地面)，其中，高度参考线和地面的位置恒定，不随用户的抖动而改变。显示屏12的图像显示在显示屏12中间，并通过透镜13在地面成像为倒立的虚像。图4b为可穿戴设备处于向上抖动状态的示意图，由于可穿戴设备向上 抖动，因而此时显示屏12和透镜13都向上偏离高度参考线，显示屏12显示的图像经过透镜13放大后投射到地面。可以看出，由于透镜12和显示屏13都向上偏离，因此在显示屏13中间显示的图像投射到地面后所形成的地面成像也向上偏离了原来的位置。在实际的使用状态下，这种情况会导致地面成像没有位于用户的正前方附近，而是位于前方很远的位置，不利于用户观看。因此，为了确保用户的正常观察，如图4c所示，通过可穿戴设备的抖动检测装置80检测可穿戴设备的抖动方向和抖动位移，然后基于可穿戴设备的抖动方向和抖动位移确定补偿量，比如显示屏13显示的图像被控制器20控制而向上偏移该补偿量进行补偿，使得投射到地面上的成像向下偏移，从而恢复到原来的位置，其具体防抖的示意图如图5所示。由此可见，图像的补偿移动方向与抖动的方向一致，比如向上抖动时，显示屏的图像也向上移动进行补偿，从而确保投影在地面上的成像不致于偏离过多的位置。
可选地，在以上步骤S301之前，上述方法还包括：
可穿戴设备通过可穿戴设备的心率传感器30检测人体心率，可穿戴设备的控制器20发送的信号包括心率信号，以使得可穿戴设备的微型投影器10将心率信号进行投影。
可选地，上述方法还包括：
可穿戴设备通过可穿戴设备的加速度传感器100检测用户的加速度，可穿戴设备的控制器20发送的信号包括用户的加速度，以使得可穿戴设备的微型投影器10将用户的加速度进行投影。
可选地，上述方法还包括
可穿戴设备通过可穿戴设备的定位装置90检测用户的当前地理位置，可穿戴设备的控制器20发送的信号包括用户的当前地理位置，以使得可穿戴设备的微型投影器10将用户的当前地理位置进行投影。
可选地，上述方法还包括：
可穿戴设备通过可穿戴设备的控制器20获取用户通过可穿戴设备的柔性触摸屏50输入的路线信息，以及根据用户当前地理位置和路线信息确定导航方向，可穿戴设备的控制器20发送的信号包括导航方向，以使得可穿戴设备的微型投影器10将导航方向进行投影。
举例来说，用户在跑步前，可通过柔性触摸屏50设定好跑步路线，当用户跑步，且佩戴可穿戴设备时，可穿戴设备可检测当前地理位置，可穿戴设备可根据当前地理位置以及跑步路线导航方向，并通过投影该导航方向以达到为用户导航的目的。当然，该跑步路线可以不是用户通过柔性触摸屏60设定的，可以是用户通过手机设定好然后向可穿戴设备的通信模块70发送过来的，本发明不作限定。
另外，当用户跑步时，可穿戴设备还可检测用户的心率、用户的加速度、用户的速度和用户当前的地理位置,并通过微型投影器100将这些信息一并投影，以供用户查看。
可选地，上述方法还包括：
可穿戴设备通过可穿戴设备的通信模块60接收其他设备发送的信息；
可穿戴设通过可穿戴设备的控制器20控制可穿戴设备的微型投影器根据该信息进行投影。
举例来说，当多个用户穿戴可穿戴设备进行比赛时，每个用户对应的可穿戴设备均与网络服务器连接，网络服务器根据每个用户的当前位置进行实时排名，然后向每个用户对应的可穿戴设备发送对应的实时排名，可穿戴设备的微型投影器20将用户的实时排名投射在地面上，从而提醒用户。另外，每个用户对应的可穿戴设备相互联网，每个用户对应的可穿戴设备可通过通信模块70获取其他可穿戴设备的当前位置，然后确定自身的实时排名，最后通过微型投影器20将用户的实时排名投射在地面上，从而提醒用户。这种提醒方式在参与人数众多的比赛(比如大型马拉松)当中较为适用，避免因为人多而无法实时得知准确排名的情况。
可选的，上述方法还包括：
可穿戴设备可通过感测装置70检测可穿戴设备与其他设备之间的距离；
在可穿戴设备的控制器20检测到某个设备接近可穿戴设备时，控制可穿戴设备进行提醒。
举例来说，多个可穿戴设备可相互联网，因此每个可穿戴设备可通过自身与其他可穿戴设备的通信确定自身与其他设备之间的距离，从而实现在身后有其他人接近(比如距离0.1米、0.2米、0.3米、1米或其他值)时发出提醒的 功能，督促用户加快速度。提醒的方式可以为振动、图像闪烁、文字提醒、呼吸灯等等。
可选的，上述方法还包括：
可穿戴设备通过可穿戴设备的速度传感器100和高度传感器110分别检测用户的速度和用户的海拔高度，可穿戴设备的控制器20发送的信号包括用户的速度和用户的海拔高度，以使得可穿戴设备的微型投影器10将用户的速度和用户的海拔高度进行投影。
以上所述，以上实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的范围。
