Detailed ways

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

In order to solve the technical problem that the user has insufficient operation convenience in displaying the brightness adjustment in the process of using the head mounted display device in the conventional technology, in the embodiment, a brightness adjustment method of the head mounted display device is proposed, and the method is Implementation can rely on a computer program that can run on a head mounted display device or on a computer host connected to the head mounted display device.

Referring to FIG. 1, a head-mounted display device C1 is used as a display device of the computer device, and a computer host device A is connected. The brightness adjustment method of the head-mounted display device can be run on the computer host. Referring to FIG. 2, a computer host running the brightness adjustment method of the above-described head mounted display device C2 can also be integrated into the head mounted display device C2.

It should be noted that the external controller B1 or B2, for example, a game controller, a joystick, and the like are also connected to the head mounted display device C2 in FIG. 1 or the head mounted display device C2 in FIG. The user can input operational commands via an external controller.

It should be noted that, as shown in FIG. 3, the brightness adjustment method of the above-mentioned head mounted display device is based on A head mounted display device with a light intensity sensor. The light intensity sensor can sense the intensity of ambient light, for example, the light intensity value of the ambient light on which the display device is placed.

Specifically, as shown in FIG. 4, the brightness adjustment method of the above-mentioned head mounted display device includes the following steps:

Step S101: Determine whether the head-mounted display device is in a power-on state; if yes, execute step S102: control the light sensor to detect an ambient light intensity value of the head-mounted display device, and if not, do not process.

When the user turns on the head mounted display device through the power button on the head mounted display device, the head mounted display device is in a power on state. For example, the head mounted display device is activated by a POWER button on a head mounted display device, indicating that the user needs to use the head mounted display device. At this time, the head-mounted display device is in the power-on state, and the display screen of the head-mounted display device is in the working mode, and it is necessary to judge whether the display brightness of the display screen is at an appropriate brightness. If not, the display brightness needs to be adjusted.

Specifically, the ambient light intensity value is detected by the light intensity sensor disposed on the head mounted display device, that is, the intensity of the light in the environment in which the current head mounted display device is located is detected. For example, when the environment in which the head-mounted display device is placed is in a hot day environment, the corresponding ambient light intensity value is large; when the environment in which the head-mounted display device is located is in a night environment, the corresponding ambient light intensity value is compared. small.

Step S103: Determine an initial display brightness of the display device with the head mounted display device according to the detected ambient light intensity value, wherein the initial display brightness corresponds to the ambient light intensity value.

In this embodiment, the brightness or light intensity perceived by the user's eyes is different under different ambient light intensity values, but the brightness or light perceived by the user's eyes after wearing the above-mentioned head mounted display device. The intensity is determined by the display brightness of the display of the head mounted display device.

If the current ambient light intensity value is small, and the display brightness of the display screen of the head-mounted display device is large, when the user uses the head-mounted display device, the eye enters a light with a relatively small brightness. In the environment, the user's eyes will feel extreme discomfort. Therefore, in order to enable the user to feel uncomfortable in the process of using the head-mounted display device, the user's eyes do not feel the change in brightness perceived by the eyes, and the initial display brightness of the head-mounted display device when the head-mounted display device is turned on The value needs to adapt to the specific feelings of the user's eyes.

Specifically, different display brightness is set for different ambient light intensity values, and the initial display brightness of the head mounted display device is determined by the ambient light intensity when the head mounted display device is in the power on state The value is determined. That is to say, the greater the ambient light intensity value, the greater the initial display brightness of the corresponding display screen, that is, the brighter the display screen; correspondingly, the smaller the ambient light intensity value, the smaller the initial display brightness of the corresponding display screen. , that is, the darker the display screen.

Determining an initial display brightness of the head mounted display device according to the initial display brightness of the head mounted display device detected by the light intensity sensor, and adjusting the display brightness of the head mounted display device according to the initial display brightness, that is, adjusting To the initial display brightness.

Specifically, a mapping relationship between the preset ambient light intensity value and the initial display brightness is obtained, and then the display brightness corresponding to the detected ambient light intensity value, that is, the initial display brightness is determined according to the mapping relationship. The display brightness of the current head mounted display device is then adjusted according to the determined initial display brightness, for example, the display brightness of the display screen of the head mounted display device is set to the initial display brightness.

For example, the initial display brightness Y and the ambient light intensity value X may be in a proportional relationship, a one-time function in which the proportional coefficient is a positive number, or other positive correlation. That is to say, the larger the ambient light intensity value X is, the larger the initial display luminance Y is. For example, the mapping relationship between the initial display brightness Y and the ambient light intensity value X may be: Y=kX, where k>0.

In another optional embodiment, the process of determining the initial display brightness may further be: acquiring a mapping relationship between a preset ambient light intensity value interval and an initial display brightness; and acquiring the detected ambient light intensity value. a target ambient light intensity value interval; searching for the target initial display brightness corresponding to the target ambient light intensity value interval as the initial display brightness corresponding to the detected ambient light intensity value according to the mapping relationship.

That is to say, the system presets or user-defined the correspondence between the initial display brightness and the ambient light intensity value interval, for example, the ambient light intensity is divided into sections, and the ambient light intensity value is set according to the preset interval size. Divided into a number of intervals, and each ambient light intensity value interval corresponds to an initial display brightness. That is to say, the initial display brightness corresponding to each ambient light intensity value interval is determined.

Step S104: Acquire a target brightness of the head mounted display device.

In this embodiment, after the head mounted display device is turned on, the initial display brightness matching the current ambient light level merely ensures that the user is not stimulated when the head mounted display device is first used. However, the initial display brightness that matches the current ambient light intensity value is not necessarily the optimal display brightness of the head mounted display device. In order to ensure the user's best use of the head-mounted display device In this embodiment, after the user's eyes adapt to the current display brightness of the head-mounted display device, the display brightness of the head-mounted display device can be adjusted to the optimal display brightness, that is, the target brightness.

In this embodiment, the optimal display brightness of the current head mounted display device is set in advance, for example, the optimal display brightness set by the system by default, or the optimal viewing display brightness set by the user according to his own needs. . It should be noted that the optimal display brightness is the target brightness.

Step S105: Stepwise adjust the display brightness of the head mounted display device display device from the initial display brightness to the target brightness according to a preset manner.

In this embodiment, when the display brightness of the display device of the head mounted display device is adjusted to the most suitable target brightness, the display brightness of the display device of the head mounted display device is not directly adjusted to the target brightness, but is required. An adjustment process, for example, gradually adjusts the display brightness of the display device of the head mounted display device to the target brightness according to a preset adjustment manner.

For example, when the initial display brightness of the head mounted display device is 1 and the target brightness is 9, the display brightness of the display screen of the head mounted display device needs to be adjusted from 1 to 9, in the process, the head display is not directly displayed. The display brightness of the display of the device is directly adjusted from 1 to 9, but a preset adjustment mode is set.

The preset manner may be that the brightness is adjusted according to a preset adjustment brightness adjustment speed, for example, setting the adjustment amplitude of each adjustment, and then adjusting the amplitude according to the set adjustment amplitude for each head. The display brightness of the display device of the display device is adjusted.

For example, if the preset adjustment brightness adjustment speed is 2, when the display brightness of the display screen of the head mounted display device is adjusted, the adjustment of the display brightness is completed by 1>3>5>7>9 four times adjustment. That is to say, with the present invention, in the process of adjusting the display brightness of the display screen of the head mounted display device, there is no flickering, and the display brightness is slowly adjusted from the current display brightness to The target display brightness avoids the user's discomfort in the process of displaying the brightness adjustment, and improves the user's experience in using the head mounted display device.

Specifically, in a specific embodiment, the “preset mode” of gradually adjusting the display brightness of the head mounted display device display device from the initial display brightness to the target brightness according to a preset manner is Calculating a difference between the initial display brightness and the target brightness; calculating a step required to adjust the initial display brightness to the target brightness according to the difference; and, according to the calculated step The display device of the head mounted display device is adjusted from the initial display brightness to The target brightness.

That is, the step of adjusting at the time of adjusting the display brightness is determined based on the difference between the initial display brightness and the target brightness described above, and then based on the difference. It should be noted that the calculation of the steps required to adjust the initial display brightness to the target brightness may be performed according to a preset algorithm, for example, calculating the number of adjustments of the display brightness adjustment and the brightness adjustment of each time. Increase or decrease. That is, the step of adjusting the display brightness is determined based on the difference between the initial display brightness and the target brightness.

Specifically, a ratio of the difference to a preset adjustment duration is obtained, and the number of times of brightness adjustment and the brightness amplitude of each adjustment are determined according to the ratio; and then, according to the number of times of the brightness adjustment and the brightness of each adjustment The amplitude adjusts the head mounted display device from an initial display brightness to the target brightness. The preset adjustment duration may be a fixed adjustment duration set by the system or the user, for example, 10s, or 1min.

It should be noted that, in this embodiment, the display brightness is not immediately adjusted to the target brightness after the display brightness of the display device of the head mounted display device is adjusted to the initial display brightness. Since the user's eyes may not yet be adapted to the display or change of the brightness of the display device of the head mounted display device, the display brightness of the display device of the head mounted display device may be adjusted to the initial display brightness for a certain time. The step of gradually adjusting the display brightness of the head mounted display device display device from the initial display brightness to the target brightness in a preset manner.

Specifically, before the acquiring the target brightness corresponding to the head mounted display device, the method further includes: detecting a continuous display duration of the initial display brightness and determining whether the continuous display duration exceeds a preset threshold; when the continuous display When the duration exceeds a preset threshold, the target brightness with the head mounted display device is acquired.

That is, after adjusting the display brightness of the head mounted display device to the initial display brightness, a timer is started to detect the continuous display duration of the initial display brightness, and then it is determined whether the continuous display duration exceeds a preset duration threshold (eg, 2min). The preset duration threshold is a time set by the system or the user to buffer the eyes of the user. Then, when the duration of the continuous display is greater than the preset duration threshold, it indicates that the user's eyes have adapted to the display brightness environment of the head mounted display device, and the display brightness of the head mounted display device can be continuously adjusted to the most appropriate target brightness.

The above trigger adjusts the display brightness of the head mounted display device to a preset condition of the second display continuous reading. Therefore, the duration after the display brightness of the head mounted display device is set to the initial display brightness exceeds a preset duration threshold. The preset duration threshold is an adaptation time for the user's eyes to adapt to the display brightness of the display screen of the head-mounted display device.

In another optional embodiment, after the user turns on the head mounted display device, the head mounted display device is not necessarily used immediately, and the head mounted display device may be turned on for later use; therefore, in order to improve the head The accuracy of the display brightness of the display device is adjusted. In this embodiment, it is also necessary to determine whether the user wears and uses the head mounted display device.

Specifically, the head mounted display device further includes a proximity sensor; and before the controlling the light sensor detects the ambient light intensity value of the head mounted display device, the method further includes: controlling the proximity sensor to detect the corresponding to the head mounted display device a distance value of the proximity object; determining, according to the distance value, whether the head mounted display device enters a wearing state; and when the head mounted display device enters a wearing state, controlling the light sensor to detect that the head mounted display device is located Ambient light intensity value.

When an object approaches the head mounted display device, the proximity sensor disposed in the head mounted display device detects the approach of the object and detects the distance value between the head mounted display device and the approaching object. It should be noted that, in this embodiment, the head mounted display device is a head-mounted visual helmet. Therefore, when the distance between the head mounted display device and the proximity object is detected, the detection may be head-mounted. The area corresponding to the auricle on the helmet, or the distance between the corresponding area of the eye and the approaching object, so the area corresponding to the auricle on the head-mounted visual helmet, or the area corresponding to the eye and the approaching object The distance value can more accurately indicate whether the head-mounted visual helmet is being worn on the user's head.

After obtaining the distance value of the proximity of the head-mounted display device, determining whether the head-mounted display device enters the wearing state according to the distance value, for example, if the detected distance value is 20 cm, the head-mounted display device does not enter the wearing state. State, if the distance value is detected to be 0.1 cm, the head mounted display device enters the wearing state. Specifically, a distance threshold may be preset, and when the distance value is less than the distance threshold, it is determined that the head mounted display device enters the wearing state.

It should be noted that, in this embodiment, the distance value of the proximity of the head-mounted display device detected by the proximity sensor may be more than one, for example, corresponding to the left ear ear and the right ear ear of the head-mounted visual helmet respectively. The areas are respectively provided with a proximity sensor, and in the above-described process of detecting the distance value of the proximity of the display device, the distance values of the proximity objects are respectively detected by the two sensors disposed on the head mounted display device. In another embodiment, a proximity sensor disposed on the head mounted display device The number can be any value, so that the distance value of the proximity object is detected in various aspects during the detection of the distance value of the head-mounted visible proximity object, so as to achieve a more prepared distance value describing the proximity of the head-mounted display device. the goal of.

Further, in the case where the number of proximity sensors provided on the head mounted display device is plural, there are also a plurality of distance values of the corresponding detected proximity objects, and therefore, in determining the process of whether the head mounted display device enters the wearing state In the meantime, it is necessary to simultaneously consider the distance value of the proximity detected by the plurality of proximity sensors. For example, it may be determined that the head mounted display device enters the wearing state when the plurality of distance values are less than the preset distance threshold. In another embodiment, the average value of the plurality of distance values may be set to be smaller than the preset. The distance threshold determines that the head mounted display device enters the wearing state. It should be noted that, in this embodiment, another correspondence relationship between the wearing state and the plurality of distance values may be set.
