According to the method and the device, the user can effectively protect the watching privacy of the user when the user does not wear the virtual reality equipment, and the privacy and the safety of the user using the virtual reality equipment are improved.
Referring to fig. 1, fig. 1 is a schematic flow chart of an apparatus control method provided in an embodiment of the present application, and the method is applied to the virtual reality apparatus and includes the following steps.
Step 10, when detecting that the virtual reality equipment is in a wearing state, an equipment unlocking device obtains a first time length of the virtual reality equipment which is in an unworn state last time;
the virtual reality device comprises a wearing state and a non-wearing state, and particularly comprises a wearing touch sensor and is used for detecting the wearing state of the virtual reality device through the wearing sensor.
Optionally, the wearing sensor is an infrared sensor, the infrared sensor is arranged on the virtual reality device, when the user wears the virtual reality device, the infrared sensor is blocked by the user, so that it is determined that the virtual reality device is currently in a wearing state, and when the infrared sensor is not blocked, the virtual reality device is not in the wearing state.
Optionally, the wearing sensor is a contact sensor, when the user wears the virtual reality device, the skin of the user contacts with the contact sensor, so that the virtual reality device is judged to be in a wearing state, and after the user takes off the virtual reality device, the skin of the user is separated from the contact sensor, so that the virtual display device is in an unworn state.
In an embodiment, after a user wears the virtual reality device for 10 minutes and takes off the virtual reality device, the virtual reality device detects that the virtual reality device is switched from a wearing state to an unworn state through a wearing sensor, and starts to record a first duration of the virtual reality device in the unworn state, and after 5 minutes, when the virtual reality device detects that the user continues to use, the virtual reality device stops timing of the first duration and determines that the first duration is 5 minutes. In addition, when the unworn state is detected next time, zero clearing processing is carried out on the last time of 5 minutes of the first time length, so that errors in the next time of recording the unworn state are avoided.
Step 20, if the first duration is longer than a first preset duration, the equipment unlocking device controls the photographing device to acquire first image information of the eyes of the user;
wherein the first preset time period may be 20 seconds, 30 seconds or other time periods.
The first image information is image information obtained by photographing the eye region of the user by the photographing device.

And the equipment unlocking device photographs the eye region of the user according to the adjusted f-number to acquire first image information.
For example, in order to ensure that the photographing device can acquire a clear and high-contrast image, when acquiring the first image information, the photographing device needs to first determine the brightness of the photographing environment, where the brightness is determined according to the current display image of the display device, and when the brightness of the display image is higher, the brightness is higher, and when the brightness of the display image is lower, the brightness is lower. And after the brightness of the photographing environment is determined, adjusting the f-number of the photographing device according to the brightness, and controlling the photographing device to photograph the eye region of the user to acquire first image information.
Therefore, the light inlet quantity of the photographing device is controlled, the first image information acquired by the photographing device is ensured to have approximate image brightness, and the problem that the difficulty of processing the first image information is increased subsequently due to the fact that the image brightness of the first image information at different moments is inconsistent when the photographing device acquires the first image information is solved.
Optionally, if the first duration is less than a second preset duration, the virtual display device is controlled to continue recording the first duration, where the second preset duration is less than the first preset duration. Specifically, when a user wants to temporarily observe the display content of the display screen in the virtual reality device, the user usually only takes up the virtual reality device to observe, in order to avoid misjudgment of the virtual reality device, when the first duration is smaller than the second preset duration, it is determined that the wearing state judged by the virtual reality device is misjudgment, and the first duration is continuously recorded.

wherein the first threshold is 20, 30 or other values.
In an embodiment, the first threshold is 27, and when the virtual reality device determines that the safety index corresponding to the pre-stored iris feature is 32, the safety index is greater than the first threshold, so that the virtual reality device lights up the display screen and displays the display content in front of the display screen.
wherein the second threshold is 5, 10, or other value.
In an embodiment, the first threshold is 27, the second threshold is 13, and when the virtual reality device determines that the safety index is 20, since the safety index is greater than the second threshold and smaller than the first threshold, after the virtual reality device lights up the display screen, an unlocking interface is displayed, where the unlocking interface includes at least two trigger points.
In another embodiment, when the virtual reality device determines that the safety index is 10, since the safety index is smaller than the second threshold, the virtual reality device sends a prompt message to a currently worn user that the content of the display screen cannot be viewed after the display screen is lit up.
wherein, control the device of shooing obtains a plurality of second image information of user's eyes, include:
the equipment unlocking device determines the brightness of the eye area of the user through the photographing device.
And the equipment unlocking device adjusts the f-number of the photographing device according to the light brightness.
And the equipment unlocking device photographs the eye region of the user according to the adjusted f-number to acquire second image information.
For example, in order to ensure that the photographing device can acquire a clear image with high contrast, when the photographing device acquires the second image information, the luminance brightness in the photographing environment needs to be determined first, the luminance brightness is determined according to the current display image of the display screen, when the luminance of the display image is high, the luminance brightness is high, and when the luminance of the display image is low, the luminance brightness is low. And after the brightness of the photographing environment is determined, adjusting the f-number of the photographing device according to the brightness, and controlling the photographing device to photograph the eye region of the user to acquire second image information.
Therefore, the second image information acquired by the photographing device is ensured to have approximate image brightness by controlling the light incoming amount of the photographing device, so that the problem that the subsequent difficulty in processing the second image information is increased due to inconsistent image brightness of the second image information at different moments when the photographing device acquires the second image information is solved.
