EXAMPLE III
The embodiment provides a power consumption control method of a split type VR device, which is applied to a host end of the split type VR device. As shown in fig. 3 and 4, the method includes:
step S301, the VR equipment is in a normal operation mode.
The user is using the VR device normally. At this time, if the following three cases satisfying the low power consumption operation occur, the execution is performed according to the respective processing flows.
The first situation is that when the power key of the host computer is monitored to be pressed, the following steps are carried out:
step S302, monitoring that a power key of a host is pressed;
step S303, sending an HMD low power consumption control instruction to the head mounted display;
and step S304, switching the control host from the normal operation mode to a low power consumption mode.
Wherein, the order of step S303 and step S304 may be interchanged.
The second situation is that the connection between the head-mounted display and the host computer is detected to be disconnected, and the method comprises the following steps:
step S305, monitoring the disconnection between the head-mounted display and the host;
and step S304, switching the control host from the normal operation mode to a low power consumption mode.
For example, the user disconnects the connection cable between the host and the head mounted display, at which time the head mounted display is powered down. And the host monitors disconnection, starts a timer, records disconnection time, and controls the host to be switched from a normal operation mode to a low power consumption mode if the disconnection time exceeds a set time.
The third situation is that a host power saving signal sent by the head-mounted display is received, and the following steps are carried out:
step S306, receiving a host power saving signal sent by the head-mounted display;
and step S304, switching the control host from the normal operation mode to a low power consumption mode.
The low power consumption mode may include a standby mode and a sleep mode, among others. The standby mode means that power supply to other devices is interrupted except for the memory, which maintains data therein by means of power, and can be quickly restored to a state before standby when it is desired to restore a normal operation state. The sleep mode refers to that the system completely transfers the data in the memory to the memory and then turns off the power supply of other devices except the memory. When the normal operation mode is expected to be recovered, if the power supply is not abnormal in the sleep mode process, the data can be directly recovered from the memory, and the speed is high. If the power supply is abnormal in the sleep mode process, the data can be recovered from the memory, and the data cannot be lost.
And when the head-mounted display monitors that the head is removed from the host by the user, a host power saving signal is sent to the host. The host determines that a host power saving signal sent by the head-mounted display is received, and switches from a normal operation mode to a standby mode; starting a timer and recording the standby time of the host; and if the standby time reaches or exceeds a set threshold, the control host is switched from the standby mode to the sleep mode.
In step S401, the VR device is in a low power consumption mode.
When the VR device is in the low power consumption mode, if the following three conditions occur, the following three conditions are also executed according to the respective processing flows.
The first situation is that when the power key of the host computer is monitored to be pressed, the following steps are carried out:
step S402, monitoring that a power key of a host is pressed;
step S403, sending an HMD normal operation control instruction to the head mounted display;
and step S404, switching the control host from the low power consumption mode to a normal operation mode.
Wherein, the order of step S403 and step S404 may be interchanged.
The second situation is that when the connection between the head-mounted display and the host is monitored to be reestablished, the following steps are carried out:
step S305, monitoring that the connection between the head-mounted display and the host is reestablished;
and step S304, switching the control host from the low power consumption mode to a normal operation mode.
For example, currently the host is in a low power mode and the head mounted display is in a powered down state. At this time, the user connects the cable between the head mounted display and the host, the head mounted display is powered on first, then sends a level signal of a rising edge, and transmits the level signal to the host through the cable, and then the head mounted display enters a normal operation mode. And awakening the host end by the rising edge level, determining that the connection between the head-mounted display and the host is reestablished, enabling the host to enter a normal operation mode, and finally enabling the host and the head-mounted display to be in the normal operation mode.
The third situation is that a host normal operation signal sent by the head-mounted display is received, and the third situation is executed according to the following steps:
step S306, receiving a host normal operation signal sent by the head-mounted display;
and step S304, switching the control host from the low power consumption mode to a normal operation mode.
And when the head-mounted display monitors that the head-mounted display is placed on the head of the user, sending a normal operation signal of the host to the host. And the host determines that a host normal operation signal sent by the head-mounted display is received, and switches from the low-power-consumption mode to the normal operation mode. The low power consumption mode here may be a standby mode or a low power consumption mode.
Example four
The embodiment provides a power consumption control method of a split type VR device, which is applied to a head-mounted display end of the split type VR device. As shown in fig. 5 and 6, the method includes:
step S501, the VR equipment is in a normal operation mode.
The user is using the VR device normally. At this time, if the following two cases occur, they are executed according to the respective processing flows.
The first case is that the head mounted display is detected to be removed from the user's head, and the following steps are performed:
step S502, monitoring that the head-mounted display is detached from the head of the user;
step S503, sending a host power saving signal to the host;
and step S504, controlling the head-mounted display to be switched from the normal operation mode to the low power consumption mode.
Wherein, the order of step S503 and step S504 may be interchanged.
When the VR device is in a normal operation mode, it is desirable to monitor in real time whether the head mounted display is removed from the user's head. The distance sensor can be used only to monitor whether the head mounted display is removed from the head of the user, and the specific method can be as follows: receiving a distance value between the head-mounted display and the head of the user, which is acquired by the distance sensor; when the distance value is larger than the set distance threshold value, the head-mounted display is judged to be detached from the head of the user. A combination of distance sensors and optical sensors may also be used to monitor whether the head mounted display is removed from the user's head by: receiving a distance value between the head-mounted display and the head of the user, which is acquired by the distance sensor; when the distance value is larger than a set distance critical value, receiving a brightness value sensed by the optical sensor; when the brightness value is larger than the set brightness critical value, the head-mounted display is judged to be detached from the head of the user.
Step S504 may be implemented as follows: controlling the head-mounted display to be switched from a normal operation mode to a standby mode; starting a timer and recording the standby time of the head-mounted display; and if the standby time reaches or exceeds a set threshold, controlling the head-mounted display to be switched from the standby mode to the sleep mode.
The second case is that the HMD low-power consumption control instruction sent by the host computer is received, and the steps are executed as follows:
step S505, receiving an HMD low power consumption control instruction sent by a host;
and step S304, controlling the head-mounted display to be switched from the normal operation mode to the low power consumption mode.
When the user presses a power key on the host, the host sends an HMD low power control instruction to the head mounted display. When the head-mounted display is determined to receive the HMD low-power control instruction, detecting whether the head-mounted display is taken down from the head of a user; if yes, controlling the head-mounted display to be switched from the normal operation mode to the sleep mode; if not, controlling the head-mounted display to be switched from the normal operation mode to the standby mode, and continuously monitoring whether the head-mounted display is taken down from the head of the user; and when the head-mounted display is monitored to be removed from the head of the user, controlling the head-mounted display to be switched from the standby mode to the sleep mode.
In step S601, the VR device is in a low power consumption mode.
When the VR device is in the low power consumption mode, if the following two conditions occur, the following two conditions are also executed according to the respective processing flows.
The first case is where the head mounted display is detected to be positioned on the user's head, and is performed as follows:
step S602, monitoring that the head-mounted display is placed on the head of a user;
step S603, sending a host normal operation signal to the host;
and step S604, controlling the head-mounted display to be switched from the low power consumption mode to the normal operation mode.
Wherein, the order of step S603 and step S604 may be interchanged.
When the VR device is in a low power mode, it is desirable to monitor in real time whether the head mounted display is placed on the user's head. The distance sensor can be used only to monitor whether the head mounted display is placed on the head of the user, and the specific method can be as follows: receiving a distance value between the head-mounted display and the head of the user, which is acquired by the distance sensor; when the distance value is smaller than the set distance critical value, the head-mounted display is judged to be placed on the head of the user. A combination of a distance sensor and an optical sensor may also be used to monitor whether the head mounted display is placed on the user's head, which may be: receiving a distance value between the head-mounted display and the head of the user, which is acquired by the distance sensor; when the distance value is smaller than a set distance critical value, receiving a brightness value sensed by the optical sensor; when the brightness value is smaller than the set brightness critical value, the head-mounted display is judged to be placed on the head of the user.
The second case is that the normal operation control instruction of the HMD sent by the host computer is received, and the steps are executed as follows:
step S605, receiving an HMD normal operation control instruction sent by a host;
and step S604, controlling the head-mounted display to be switched from the low power consumption mode to the normal operation mode.
When the user presses a power key on the host, the host sends HMD normal operation control instructions to the head-mounted display with the VR device in a low power mode. The head-mounted display receives the HMD low-power-consumption control instruction and is switched to a normal operation mode from a low-power-consumption mode. The low power consumption mode here may be a standby mode or a low power consumption mode.
