Based on the hardware architecture of the wearable device, an embodiment of the control method of the wearable device is provided.
Referring to fig. 2, fig. 2 is a first embodiment of a control method of a wearable device of the present invention, the control method of the wearable device includes the following steps:
at present, wearable equipment can support a plurality of applications, such as audio playing, games, reading and communication prompts can be smoothly operated on the wearable equipment, but the wearable equipment is affected by the size and the weight of the wearable equipment on wearing experience, the battery of the wearable equipment is generally small, the endurance is weak, and therefore the energy consumption of the wearable equipment needs to be reduced. In order to solve the above problem, the present invention provides a method for controlling a wearable device, including the steps of:
step S10, obtaining use scene information of the wearable device, wherein the use scene information comprises ambient brightness information and a use state, and the use state comprises a motion state or a static state;
the execution subject of the control method of the wearable device can be a device for adjusting the screen refreshing frequency of the wearable device. The device can be a wearable device or an external host, and can also be a hardware module and/or a software module in the wearable device or the external host. The wearable device can be a head-mounted device such as AR/VR head glasses, AR/VR helmet and the like, or a wrist band device such as a bracelet and the like, or other wearable devices. The wearable device can support functions such as information prompting, video playing, music playing, communication calling and games. Referring to fig. 7, fig. 7 is a schematic structural diagram of the wearable device of the present invention. Be provided with ambient light sensor in the wearable equipment, can gather ambient light intensity in order to obtain ambient brightness information. An Inertial Measurement Unit (IMU) is also provided in the wearable device, which may be a combined unit consisting of 3 accelerometers and 3 gyroscopes, the acceleration and gyroscope sensors being mounted on mutually perpendicular measurement axes. In a cartesian coordinate system having an x-axis, a y-axis, and a z-axis, the sensor is capable of measuring linear motion in the directions of the respective axes, as well as rotational motion about the respective axes. The inertial measurement unit is used for detecting the use state of the wearable device.
It should be noted that human eyes have different photoreceptor cells, the activity degree under different illumination environments is different, the sensitivity to the flicker frequency is also different, rod cells are active under dark environment, the rod cells are insensitive to the change of light, the rod cells transmit light signals slower than cone cells, and the maximum frequency which can be sensed after the rod cells receive stimulation for about 100ms is also reduced. Therefore, in different ambient light environments, a fixed high refresh rate may not be better experienced, and it also represents a waste of energy consumption. In the process of visual discrimination, the flash fusion feeling means that when a person looks at a flash with lower intermittent frequency, the flash feeling of alternating light and shade is obtained, and when the intermittent frequency of the flash is increased, the person looks at the flash instead of the flash light, but the flash light is stable and continuous, and the phenomenon is called flash fusion. The flicker fusion critical ratio is the minimum frequency of stimulus that can cause flicker fusion sensation, and represents the limit of the resolving time capability of the visual system, and the relationship between the flicker intensity and the flicker fusion critical ratio is such that the higher the ambient light intensity, the larger the value of the flicker fusion critical ratio. That is to say, when the image luminance that wearable equipment shows is lower, the marginal frequency of flash of light that people's eye felt is lower, and wearable equipment only needs lower screen refresh frequency can let human vision system see stable continuous light thereby can not influence the experience of user to wearable equipment other functions.
It should be noted that, according to the usage scenario of the wearable device, when a dynamic video streaming function is required, such as a game, a video, etc., the user generally has a non-moving posture, and the usage state of the wearable device is a static state. When the user is in a dynamic posture such as walking, running or jumping, the required function is to statically display information or simply switch display contents such as notification reading and navigation information prompting. In addition, when the user is in a motion state, the vision is interfered by the surrounding environment, the attention cannot be focused on the content displayed on the screen, so that the sensitivity to the refreshing frequency is lower than that in a static state, the use state of the wearable device can be used as the basis for function classification, and the screen refreshing frequency can be adjusted according to the use state of the wearable device.
Step S20, acquiring a target refreshing frequency of the wearable device according to the using scene information;
optionally, the environment brightness information in the scene information may be divided into three types, namely a dark environment, a normal environment, and a bright environment in advance, and of course, the environment brightness information may also be divided into a plurality of brightness levels according to a supportable display brightness range of the wearable device, and the lower the brightness level is, the lower the refresh frequency is. The using state comprises a moving state and a static state, and the refreshing frequency corresponding to the moving state is lower than that corresponding to the static state.
Alternatively, in one embodiment, three types of dark environment, normal environment, and bright environment are taken as examples. The screen refresh frequency of the wearable device is set to three levels, namely a low refresh frequency, a medium refresh frequency and a high refresh frequency, while three brightness environment types are set. The low refresh frequency may be 10Hz, and the corresponding display pixels are refreshed once every 100 milliseconds, and the refresh frequency corresponds to the change of the graph which can be sensed by the visual cells in the dark environment; the middle refreshing frequency is 30Hz, and the corresponding display pixels are refreshed once every 33.3 milliseconds; the high refresh rate is 60Hz and the corresponding display pixels are refreshed every 16.6 milliseconds. The wearable device is not limited to the above defined types, with performance support.
And step S30, setting the refresh frequency of the wearable device as the target refresh frequency, so as to display target content according to the target refresh frequency.
It should be noted that, if the wearable device displays a screen at another refresh frequency before the target refresh frequency is obtained, after the target refresh frequency is obtained, the original refresh frequency is adjusted to the target refresh frequency. If the wearable device does not display the picture before the target refresh frequency is acquired, setting the refresh frequency as the target refresh frequency to display the target content after the target refresh frequency is acquired. The target content is to-be-displayed content corresponding to the display requirement.
Optionally, in an embodiment, a target refresh frequency of the wearable device is obtained according to the ambient brightness information and the usage status information; adjusting the refresh frequency of the wearable device to the target refresh frequency. For example, when the ambient brightness information is a dark environment and the usage state is a motion state, acquiring a low refresh frequency, and adjusting the refresh frequency of the wearable device to the low refresh frequency such as 10 Hz; when the environment brightness information is in a dark environment and the use state is in a static state, acquiring a middle refreshing frequency, and adjusting the refreshing frequency of the wearable device to the middle refreshing frequency such as 30 Hz; when the environment brightness information is in a normal environment and the use state is in a motion state, acquiring a middle refreshing frequency, and adjusting the refreshing frequency of the wearable device to the middle refreshing frequency such as 30 Hz; when the environment brightness information is in a normal environment and the use state is in a static state, acquiring a high refresh frequency, and adjusting the refresh frequency of the wearable device to the high refresh frequency such as 60 Hz; and when the environment brightness information is a bright environment, acquiring a high refresh frequency, and adjusting the refresh frequency of the wearable device to the high refresh frequency such as 60 Hz.
Optionally, in an embodiment, a target refresh frequency of the wearable device is obtained according to the ambient brightness information; setting a refresh frequency of the wearable device to the target refresh frequency. For example, when the ambient brightness information is a dark environment, obtaining a low refresh frequency, and adjusting the refresh frequency of the wearable device to the low refresh frequency; when the environment brightness information is in a normal environment, acquiring a middle refreshing frequency, and adjusting the refreshing frequency of the wearable device to the middle refreshing frequency; and when the environment brightness information is in a bright environment, acquiring a high refreshing frequency, and adjusting the refreshing frequency of the wearable equipment to the high refreshing frequency.
Optionally, in an embodiment, a target refresh frequency of the wearable device is obtained according to the usage status; adjusting the refresh frequency of the wearable device to the target refresh frequency. For example, when the use state is a motion state, acquiring a low refresh frequency, and adjusting the refresh frequency of the wearable device to the low refresh frequency; and when the use state is a static state, acquiring a high refresh frequency, and adjusting the refresh frequency of the wearable device to the high refresh frequency.
Optionally, in another embodiment, the usage scenario information may further include a component type currently operated by the wearable device. Acquiring the current operating component type of the wearable device; when the component type meets a preset type, acquiring a low refresh frequency, and adjusting the refresh frequency of the wearable device to the low refresh frequency; and when the component type does not meet the preset type, acquiring a high refresh frequency, and adjusting the refresh frequency of the wearable device to the high refresh frequency. The component may be application information or event information. The preset types can include but are not limited to notification information prompts, time prompts, navigation information prompts and the like; the preset type is set by a user in a self-defined mode or preset by a manufacturer.
In the technical scheme provided by this embodiment, a screen refresh model is pre-established in the wearable device according to usage scene information, the usage scene information of the wearable device is detected in real time, a target refresh frequency meeting human visual system perception under a current usage scene is obtained according to the usage scene information, and the refresh frequency of the wearable device is adjusted to the target refresh frequency. Therefore, the wearable device can establish models with different refreshing frequencies according to the perception of the human visual system on the refreshing frequency in different scenes in advance, the refreshing frequency can be dynamically adjusted according to the obtained using scene information, the using scene where the current device is located can be matched, the energy consumption is reduced, and the effect that the wearable device does not influence the user experience while reducing the energy consumption is achieved.
Referring to fig. 3, fig. 3 is a second embodiment of the control method of the wearable device of the present invention, and based on the above embodiment, the step S20 includes:
step S21, acquiring the brightness level corresponding to the environment brightness information;
further, the step S21 includes:
acquiring a brightness value corresponding to the environment brightness information;
determining a display brightness value corresponding to the wearable device according to the environment brightness value;
and determining the brightness level according to the display brightness value.
It can be understood that the wearable device is preset with a display brightness value of a preset range in the manufacturing process, and the range of the display brightness of different wearable devices can be the same or different. A mapping relation value between the ambient light intensity value and the device display brightness value is preset in the wearable device, so that the wearable device can dynamically adjust the device display brightness according to the ambient light brightness, and therefore energy consumption is reduced. In this embodiment, the wearable device is divided into brightness levels of preset levels according to the range of display brightness, and the lower the display brightness level, the lower the corresponding display brightness value. An ambient light sensor in the wearable device collects ambient light, converts the ambient light into an ambient light intensity value, inputs the ambient light intensity value into a processor of the wearable device, and the processor of the wearable device acquires a display brightness value corresponding to the wearable device according to the ambient light intensity value and determines a brightness level according to the display brightness value.
And step S22, acquiring a target refresh frequency according to the brightness level and the use state.
In one embodiment, the refresh frequency corresponding to different brightness levels is different, the refresh frequency is set to a gear consistent with the brightness levels, and the lower the brightness levels, the lower the refresh frequency. In an embodiment, the refresh frequencies corresponding to different brightness level ranges are different, for example, when the brightness level is less than or equal to a first preset level, a first refresh frequency is obtained, and the refresh frequency of the wearable device is adjusted to the first refresh frequency. And when the brightness level is greater than or equal to a second preset level, acquiring a second refreshing frequency, and adjusting the refreshing frequency of the wearable device to the second refreshing frequency. And when the brightness level is greater than the first preset level and less than the second preset level, acquiring a third refreshing frequency, and adjusting the refreshing frequency of the wearable device to the third refreshing frequency. The first preset level is smaller than the second preset level, the first refresh frequency is smaller than the third refresh frequency, and the third refresh frequency is smaller than the second refresh frequency.
In the technical scheme provided by this embodiment, a mapping relationship between the ambient light intensity value and the device display brightness value and brightness levels corresponding to different display brightness values are preset in the wearable device. When the environment brightness information is obtained, obtaining the brightness level corresponding to the display brightness of the equipment according to the environment brightness information; and acquiring a target refresh frequency according to the brightness level and the use state, wherein the lower the brightness level is, the lower the refresh frequency is.
