在VR头戴设备开机后，按照一定时间间隔周期性地监测VR头戴设备受到的外部压力以及VR头戴设备与用户脸部的距离。
读取VR头戴设备受到的外部压力的数据以及VR头戴设备与用户脸部的距离的数据。当VR头戴设备受到的外部压力变大时，可能是用户握住VR设备；当VR头戴设备受到的外部压力变小时，可能是用户放开VR头戴设备；当VR头戴设备与用户脸部的距离变小时，可能是用户正在佩戴VR头戴设备；当VR头戴设备与用户脸部的距离变大时，可能是用户 正在摘下VR头戴设备。
根据VR头戴设备受到的外部压力和VR头戴设备与用户脸部的距离，来控制VR头戴设备进入休眠/唤醒状态。由于同时考虑了VR头戴设备受到的外部压力和VR头戴设备与用户脸部的距离，能够较为准确地判断用户的使用情况，防止误操作。本发明提供两种方式，控制VR头戴设备进入休眠/唤醒状态。
在第一种方式中，根据VR头戴设备受到的外部压力的变化情况和VR头戴设备与用户脸部的距离的变化情况，控制VR头戴设备进入休眠/唤醒状态。
理论上，如果VR头戴设备受到的外部压力变大和VR头戴设备与用户脸部的距离变小都满足，说明用户将要使用VR头戴设备，但是VR头戴设备受到的外部压力变大和VR头戴设备与用户脸部的距离变小可能不是同步发生的；例如，用户先握住VR头戴设备，此时VR头戴设备受到的外部压力变大，然后用户移动VR头戴设备至脸部进行佩戴，在移动佩戴VR头戴设备这段时间内，VR头戴设备与用户脸部的距离变小但是VR头戴设备受到的外部压力可能是保持不变的。同理，如果VR头戴设备受到的外部压力变小和VR头戴设备与用户脸部的距离变大都满足，说明用户将要停用VR头戴设备，但是VR头戴设备受到的外部压力变小和VR头戴设备与用户脸部的距离变大很可能不是同步发生的。
第一种方式是根据VR头戴设备受到的外部压力的最后一次变化和VR头戴设备与用户脸部的距离的最后一次变化来唤醒/休眠VR头戴设备。具体来说：
如果VR头戴设备受到的外部压力的最后一次变化为压力变小并且VR头戴设备与用户脸部的距离的最后一次变化为距离变大，则控制VR头戴设备进入休眠，即，VR头戴设备的休眠条件是VR头戴设备受到的外部压力的最后一次变化为压力变小并且VR头戴设备与用户脸部的距离的最后一次变化为距离变大。
如果VR头戴设备受到的外部压力的最后一次变化为压力变大并且VR头戴设备与用户脸部的距离的最后一次变化为距离变小，则唤醒VR头 戴设备，即，VR头戴设备的唤醒条件是VR头戴设备受到的外部压力的最后一次变化为压力变大并且VR头戴设备与用户脸部的距离的最后一次变化为距离变小。
第一种方式中，VR头戴设备的休眠条件是VR头戴设备受到的外部压力的最后一次变化为压力变小并且VR头戴设备与用户脸部的距离的最后一次变化为距离变大，VR头戴设备的唤醒条件是VR头戴设备受到的外部压力的最后一次变化为压力变大并且VR头戴设备与用户脸部的距离的最后一次变化为距离变小，能够提高唤醒/休眠操作的准确性，防止误操作。当VR头戴设备受到的外部压力的最后一次变化为压力变小和VR头戴设备与用户脸部的距离的最后一次变化为距离变大只有一个满足时，VR头戴设备的状态并不会改变。同样的，当VR头戴设备受到的外部压力的最后一次变化为压力变大和VR头戴设备与用户脸部的距离的最后一次变化为距离变小只有一个满足时，VR头戴设备的状态也不会改变。
例如，VR头戴设备原本处于唤醒状态，监测到VR头戴设备与用户脸部的距离的最后一次变化为距离变大但是VR头戴设备受到的外部压力的最后一次变化不是压力变小时，说明VR头戴设备远离用户头部但是用户并没有放开VR头戴设备，用户有可能只是调整佩戴姿态，VR头戴设备保持之前的唤醒状态不变。
例如，VR头戴设备原本处于唤醒状态，监测到VR头戴设备受到的外部压力的最后一次变化为压力变小但是VR头戴设备与用户脸部的距离的最后一次变化不是距离变大时，说明用户放开VR头戴设备但是并没有摘下VR头戴设备，VR头戴设备保持之前的唤醒状态不变。
例如，VR头戴设备原本处于休眠状态，监测到VR头戴设备受到的外部压力的最后一次变化为压力变大但是VR头戴设备与用户脸部的距离的最后一次变化不是距离变小时，说明用户握住VR头戴设备但是VR头戴设备并没有靠近用户脸部，说明用户并没有要佩戴VR头戴设备，VR头戴设备保持之前的休眠状态不变。
在其它实施例中，为了进一步防止误操作，可以将休眠条件进一步扩展为：VR头戴设备受到的外部压力的最后一次变化为压力变小、VR头戴设 备与用户脸部的距离的最后一次变化为距离变大，并且VR头戴设备与用户脸部当前的距离大于设定的第一距离阈值。第一距离阈值可以在出厂时已经设定好，也可以由用户自行设定，第一距离阈值例如可以为4cm。
在其它实施例中，为了进一步防止误操作，可以将唤醒条件进一步扩展为：VR头戴设备受到的外部压力的最后一次变化为压力变大、VR头戴设备与用户脸部的距离的最后一次变化为距离变小，并且VR头戴设备与用户脸部当前的距离小于设定的第二距离阈值。第二距离阈值可以在出厂时已经设定好，也可以由用户自行设定，第二距离阈值例如可以为2cm。
在第二方式中，判断VR头戴设备受到的外部压力与第一压力阈值、第二压力阈值的关系，以及判断VR头戴设备与用户脸部的距离与第一距离阈值、第二距离阈值的关系，来控制VR头戴设备进入休眠/唤醒状态。具体来说：
如果VR头戴设备受到的外部压力小于设定的第一压力阈值并且VR头戴设备与用户脸部的距离大于设定的第一距离阈值，说明用户没有在使用VR头戴设备，则控制VR头戴设备进入休眠状态。
如果VR头戴设备受到的外部压力大于设定的第二压力阈值并且VR头戴设备与用户脸部的距离小于设定的第二距离阈值，说明用户想要使用VR头戴设备，则唤醒VR头戴设备，
第二种方式中的第一、第二压力阈值，以及第一、第二距离阈值可以在出厂时已经设定好，也可以由用户自行设定，第一距离阈值例如可以为4cm，第二距离阈值例如可以为2cm。
为了防止误操作，如果VR头戴设备受到的外部压力小于设定的第一压力阈值和VR头戴设备与用户脸部的距离大于设定的第一距离阈值只有一项满足，VR头戴设备保持之前的状态保持；如果VR头戴设备受到的外部压力大于设定的第二压力阈值和VR头戴设备与用户脸部的距离小于设定的第二距离阈值只有一项满足，VR头戴设备保持之前的状态不变。
本发明实施例还提供了一种VR头戴设备，为其自动进行唤醒/休眠提供硬件基础，参考图1-5进行说明：
参考图1说明本发明实施例提供的VR头戴设备，VR头戴设备包括唤醒 /休眠控制电路300、至少一个压力传感器100，以及至少一个距离传感器200；压力传感器100和距离传感器200分别与唤醒/休眠控制电路300电连接。在一个实施例中，唤醒/休眠控制电路300与系统电源控制模块的控制端电连接，从而按照前述方法控制系统进入唤醒或者休眠状态。
参见图2所示，在一个实施例中，唤醒/休眠控制电路可以集成在VR头戴设备的处理器400中，也即，VR头戴设备的处理器400具有控制处理器400外围的模块及处理器400本身进入休眠和唤醒状态的功能。VR头戴设备还包括存储器，所述存储器用于存储指令，所述指令用于控制处理器400进行相应操作以实现前述VR头戴设备的控制方法。在一个实施例中，处理器400与系统电源控制模块500的控制端电连接。
从图3-图5中可以看出，压力传感器100均匀分布在VR头戴设备1的上边框11和下边框12的位置。可以在VR头戴设备的上边框11上和下边框12上设置凹槽，压力传感器100嵌入凹槽中并且嵌入以后和上边框11或下边框12形成平整表面。距离传感器200可以为红外传感器或超声波传感器，可以设置于VR头戴设备1的内侧并且位于VR头戴设备1的左透镜3和右透镜4之间，其中，VR头戴设备1的内侧是指VR头戴设备1被佩戴以后与用户脸部邻近的一侧。
将压力传感器放置在VR头戴设备的上边框和下边框的位置，是由于用户通常习惯用大拇指和其余手指分别握住上边框和下边框，将压力传感器设置在这些位置更加符合用户的操作习惯。在其它的实施例中，压力传感器可以只设置在VR头戴设备的上边框的位置。在其它实施例中，压力传感器也可以只设置在VR头戴设备的下边框的位置。在其它的实施例中，VR头戴设备中可以只设置一个压力传感器。在其它实施例中，压力传感器可以为多个，均匀分布于VR头戴设备的上边框的左右两端和下边框的左右两端。
在图3所示的实施例中，距离传感器200位于VR头戴设备1的左透镜3和右透镜4之间。在其它实施例中，距离传感器还可以位于VR头戴设备1的左透镜左侧或右透镜右侧的位置。
本发明提供的VR头戴设备，为其自动进行唤醒/休眠控制提供了硬件基础。本发明通过在VR头戴设备上添加压力传感器和距离传感器来优化VR 头戴设备的休眠/唤醒方案，由于压力传感器可以方便快速的监测到用户对VR头戴设备的操作情况，辅助距离传感器监测与用户脸部距离的变化，综合判定后自动控制VR头戴设备唤醒/休眠，不需要用户做例如打开休眠开关的额外动作，操作简单方便，给用户提供了很好的使用体验。
虽然已经通过例子对本发明的一些特定实施例进行了详细说明，但是本领域的技术人员应该理解，以上例子仅是为了进行说明，而不是为了限制本发明的范围。本领域的技术人员应该理解，可在不脱离本发明的范围的情况下，对以上实施例进行修改。本发明的范围由所附权利要求来限定。
