Figure PCTCN2020083503-appb-000001
其中，ε 0为真空介电常数，ε 0＝8.854×10 -12F/m；A为极板的遮盖面积；ε为极板间介质的相对介电系数，在空气中，ε＝1；d为两平行极板间的距离。
当d、A或ε发生变化时，都会引起电容C的变化。
在头戴电子设备100已被佩戴后，头戴电子设备100的镜腿会横跨图3示出的耳朵旁边的动脉。此时，用户的皮肤可与电容式传感器的传感器垫片构成电容器，且A和ε不会发生变化。随着脉搏的跳动，皮肤与传感器垫片之间的距离也会发生变化。在A和ε均不变的情况下，电容值的变化会随着皮肤与传感器垫片之间距离的变化而变化。因此，通过一段时间内电容值的变化频率可计算出心率。

在一些实施例中，脉搏传感器131一直处于检测脉搏的状态。
具体地，脉搏传感器131检测到至少两次，例如3-5次脉搏跳动，根据检测到该至少两次脉搏跳动耗费的时间确定脉搏跳动的频率是否在预设范围内，该预设范围为人体脉搏跳动的范围，例如可以是60-100次/分。若确定脉搏跳动的频率在上述预设范围内，则确定脉搏传感器131检测到的脉搏为人体的脉搏，确定头戴电子设备100的佩戴状态为已佩戴。

进一步地，脉搏传感器131检测出是否存在脉搏结果后，可关闭脉搏传感器，直至检测出头戴电子设备100的运动轨迹符合预设的运动轨迹，以降低脉搏传感器产生的功耗，增强头戴电子设备100的续航能力。

头戴电子设备100的弯折状态可以包括如图9所示的折叠状态和展开状态。上述弯折状态的变化可以包括从折叠状态变成展开状态，以及从展开状态变成折叠状态。
具体地，若头戴电子设备100的弯折状态发生变化，则触发脉搏传感器131检测是否存在脉搏。若存在脉搏，则确定头戴电子设备100的佩戴状态为已佩戴。若不存在脉搏，则确定头戴电子设备100的佩戴状态为未佩戴。
在一种可能的实现方式中，上述头戴电子设备100的弯折状态的变化可通过磁传感器检测。其中，磁传感器例如可以是霍尔传感器。霍尔传感器可包含输出端，输出端以电压或者电流的方式输出电信号。当输出的电信号发生跳变(从高电平变成低电平或者从低电平变成高电平)时，可确定头戴电子设备100的弯折状态发生变化。霍尔传感器在头戴电子设备中的位置如图10所示。
如图10中的a所示，在一种实现方式中，霍尔传感器可以设置在右镜腿的A1处，磁铁可以设置在镜框的A2处。其中，A1为头戴电子设备100的弯折状态为折叠状态时，右镜腿与镜框的重合处，右镜腿上的相应位置；A2为头戴电子设备100的弯折状态为折叠状态时，右镜腿与镜框的重合处镜框上的相应位置，具体可见图10中的b左边虚线框中示出的位置。
在另外一种实现方式中，霍尔传感器可以设置在左镜腿的B1处，磁铁可以设置在镜框的B2处。其中，B1为头戴电子设备100的弯折状态为折叠状态时，左镜腿与镜框的重合处，左镜腿上的相应位置；B2为头戴电子设备100的弯折状态为折叠状态时，左镜腿与镜框的重合处镜框上的相应位置，具体可见图10中的b右边虚线框中示出的位置。
在另外一种实现方式中，霍尔传感器可设置在A1和B1处，磁铁可设置在镜框的A2和B2处。
不限于此，上述霍尔传感器和磁铁的位置可相互调换，不再赘述。
在另外一种可能的实现方式中，上述头戴电子设备100的弯折状态的变化可通过两个陀螺仪传感器133检测。其中，两个陀螺仪传感器133可分别设置于头戴电子设备100的两个镜腿上。具体地，当两个镜腿上的陀螺仪传感器133输出的角速度的值互为相反数时，可确定头戴电子设备100的弯折状态发生了变化。
进一步地，脉搏传感器131检测出是否存在脉搏结果后，可关闭脉搏传感器，可关闭脉搏传感器131，直至检测到头戴电子设备100的弯折状态再次发生变化，以降低脉搏传感器131产生的功耗，增强头戴电子设备100的续航能力。
不限于通过磁传感器检测头戴电子设备100的弯折状态的变化，在具体实现中还可以将上述设置在镜腿或者镜框处的磁传感器替换成指南针，通过指南针检测到的磁力的变化确定头戴电子设备100的弯折状态的变化。若指南针检测到的磁力变大或者变小，可确定头戴电子设备100的弯折状态发生变化。
方式三：可以通过头戴电子设备100与外接设备的连接状态的变化初步检测出头戴电子设备100的佩戴状态是否发生变化。若是，则初步检测出头戴电子设备100的佩戴状态发生变化。
头戴电子设备100与外接设备的连接状态可包括连接和断开。上述连接状态的变化可以包括从断开变成连接，以及从连接变成断开。
具体地，若头戴电子设备100与外接设备的连接状态发生变化，则触发脉搏传感器131检测是否存在脉搏。若存在脉搏，则确定头戴电子设备100的佩戴状态为已佩戴。若不存在脉搏，则确定头戴电子设备100的佩戴状态为未佩戴。
具体地，如图11所示，外接设备可以是手机300，头戴电子设备100可以通过连接线400与外接设备300连接。
其中，连接线400可以通过USB Type C接口或Mini USB接口与外接设备300连接，连接线400可以通过USB接口与头戴电子设备100连接。该USB接口可以是USB3.0，用于兼容高速显示接口(display port，DP)信号传输，可以传输视音频高速数据。
此外，外接设备300可通过连接线400将外接设备300显示的画面发送至头戴电子设备100，以使用户通过头戴电子设备100查看外接设备300显示的画面。例如，外接设备300在接收用户输入的开启某游戏应用的指令后，可显示该游戏应用的画面，并通过连接线400将该画面发送至头戴电子设备100，以使用户通过头戴电子设备100查看该游戏应用的画面。可能地，外接设备300可以不显示画面，直接通过头戴电子设备100显示画面。
进一步的，脉搏传感器131检测出是否存在脉搏结果后，可关闭脉搏传感器131，直至检测到头戴电子设备100与外接设备的连接状态再次发生变化，以降低脉搏传感器131产生的功耗，增强头戴电子设备100的续航能力。
在一些实施例中，在头戴电子设备100与外接设备300连接的情况下，外接设备300检测到的用户操作可使头戴电子设备100做出响应。例如，外接设备300检测到点亮屏幕的用户操作后可触发头戴电子设备100开启脉搏传感器133检测脉搏。又例如，外接设备300检测到解锁的用户操作可触发头戴电子设备100显示解锁的画面，或可触发头戴电子设备100开启脉搏传感器133检测脉搏等。
