The specific operations may be operations in which the user plugs the head-mounted display into the host, pulls the head-mounted display out of the host in a short time, and closes the screen of the head-mounted display, and then plugs the head-mounted display into the host again. The method of the invention can be a supplementary scheme based on the existing scheme, and can also realize the awakening operation of the head-mounted display only by the method of the invention.
Fig. 1 is a flow diagram of one embodiment of a method for waking up a head mounted display for a VR host in accordance with the present invention.
According to fig. 1, the method comprises:
step S110, detecting whether an external device is connected to the VR host, if so, performing step S120, and if not, continuing to perform step S110.
The external device is specifically a device which is just connected to the VR host, and the external device is not initially connected to the VR host.
Specifically, the specific manner of establishing the connection between the external device and the VR host may be a wired connection established through a USB interface on the VR host, an HDMI interface, or the like, or a wireless connection established through radio waves or the like.
Step S120, obtaining a current parameter corresponding to the type of the external device.
In an embodiment of the present invention, as shown in fig. 2, the method for implementing step S120 may be:
and searching a pre-stored comparison table reflecting the corresponding relation between the type of the external equipment and the parameters, and determining the parameters corresponding to the type of the external equipment as the current parameters.
Specifically, when each external device is connected to the VR host by the first pass, the VR host may generate a parameter corresponding to the type of the device, and store the type of the device and the parameter thereof in the comparison table, so that when the external device is connected to the VR host again, the parameter corresponding to the type of the external device may be found by looking up the comparison table as the current parameter.
For the same type of device, e.g., two head mounted displays of the same model, the first parameter is generated when the first head mounted display first establishes a connection with the VR host, in which case if the second head mounted display first establishes a connection with the VR host, the VR host will not generate new parameters, but will instead associate the second head mounted display with the first parameter, i.e., the same type of device will correspond to the same parameter in the lookup table.
Wherein the lookup table may be implemented in a driver layer of the VR host system and sends the current parameters to the JNI layer. The JNI is specifically a Java Native Interface (Java Native Interface). The awakening process is in the application program framework layer, the driver layer is written by C + + voice, and the application program framework layer is written by Java voice, so the driver layer must inform the application program framework layer of the message inserted by the external device through the JNI layer, and the JNI layer can be used for filtering the external device just inserted, namely judging whether the type of the external device is the head-mounted display.
Step S130, determining whether the type of the external device is a head-mounted display according to the current parameters, if so, performing step S140, and if not, continuing to perform step S110.
In an embodiment of the present invention, as shown in fig. 2, the method for performing step S130 may be:
judging whether the current parameters are the same as the parameters corresponding to the head-mounted display, if so, judging that the type of the external equipment is the head-mounted display, and executing the step S140; if not, the type of the external device is determined not to be the head-mounted display, and the step S110 may be continued.
Specifically, the function of the corresponding interface in the JNI layer may be called; executing the function according to the current parameters to obtain an execution result; and judging whether the type of the external equipment is a head-mounted display or not according to the execution result.
Further, a function of a corresponding USB interface in the JNI Layer may be called through a relay HAL Layer (Hardware Abstraction Layer). The function is executed according to the current parameter, specifically, whether the current parameter is the same as the parameter corresponding to the head mounted display is compared, in the same case, the obtained execution result may be yes or 1, and in different cases, the obtained execution result may be no or 0. If the execution result is yes or 1, it may be determined that the type of the external device is the head-mounted display, and step S140 is executed; if the execution result is no or 0, it may be determined that the type of the external device is not the head-mounted display, and step S110 is executed.
Step S140, detecting whether the screen status of the external device is off, if so, performing step S150, and if not, continuing to perform step S110.
Specifically, the specific method for performing step S150 may be implemented by detecting whether the host supplies power to the external device.
In one embodiment of the present invention, the step S140 may include:
calling a screen state detection method in an application program framework layer; executing the screen detection method to obtain a return value; and judging whether the screen state of the external equipment is closed or not according to the return value.
The method for detecting the screen state may specifically be that a return value identical to a value of a variable in the method is obtained by reading the value of the variable. The screen detection method can be stored in a power management class, and when the host supplies power to the head-mounted display, the screen state of the head-mounted display is started; when the power supply of the host computer does not supply power to the head-mounted display, the screen of the head-mounted display is in a state of being closed. When the state of the host supplying power to the head-mounted display changes, the value of the variable is changed at the same time, for example, when the power supply of the host supplies power to the head-mounted display, the value of the variable is "true"; when the power supply of the host does not supply power to the head-mounted display, the value of this variable is "false". Then, when the screen of the head mounted display is in the on state, the resulting return value is "true"; when the screen of the head mount display is in the off state, the resultant return value is "false". In this way, the screen state of the head mounted display can be determined from the return value.
And step S150, supplying power to the external equipment.
Specifically, the specific method for supplying power to the external device may be implemented by calling a wake-up procedure in the application framework layer, as in the prior art. The host computer executes the awakening process to ensure that the head-mounted display connected with the host computer is awakened, namely, the host computer is ensured to supply power to the head-mounted display, so that the screen state of the head-mounted display is started.
Therefore, on the basis that the existing method cannot wake up the head-mounted display, the method disclosed by the invention is used for executing the wake-up process, so that the problem that the screen of the head-mounted display is not bright when the head-mounted display is connected to the VR host under certain specific operations can be solved, the head-mounted display is ensured to be automatically bright when being connected to the VR host, the user does not need to do the wake-up process, the user operation process is simplified, and the user experience is improved.
