Example one
Referring to fig. 1 and fig. 2, the present embodiment provides a screen locking method for a terminal connected to a headset, so that when the terminal is stored, the normal playing or display of the screen content of the terminal can still be ensured, and the dark operation and control can also be realized.
The method comprises the following steps:
first, a mask layer (shown) is placed on top of all applications in the terminal. Alternatively, the mask layer may be a transparent mask layer, or may be a customized interface pattern. The present embodiment is described with reference to a transparent mask layer.
All touch events are intercepted through the transparent shielding layer, so that the terminal still plays original app content, the head-mounted equipment connected with the terminal still can normally play terminal display content, and the terminal cannot be touched to achieve a pseudo screen locking effect.
The intercepting mode may be intercepting all touch events and not transferring to the upper layer application for processing.
The transparent mask layer has a substantially different background mask effect from the background mask effect of the current browser when the current webpage pops up (e.g., pops up a confirmation form). The application is a cross-application transparent mask implemented for native android applications, rather than for browser web pages.
Preferably, after the transparent mask layer is opened, the brightness of the terminal is automatically adjusted to be the lowest, so as to save electric quantity. The display brightness of the head-mounted equipment can be independently controlled through the brightness adjusting button arranged on the head-mounted equipment, so that the display effect of the head-mounted equipment cannot be influenced.
Through the operation, even if the terminal is accomodate in the pocket, in the package or other dark places, still can guarantee the normal broadcast of head-mounted device, and solved the mistake and touched the terminal display screen and influence the problem of broadcast.
When the user has the requirement of controlling the terminal application, the user cannot watch the terminal screen through eyes and control the terminal screen by wearing the head-mounted device. The embodiment provides a function of controlling the terminal in the dark, so that a user can control the terminal even in the dark without detaching the head-mounted device, and the function of interacting the terminal and the head-mounted device is realized.
Specifically, a key on the terminal, hereinafter referred to as a designated key, is designated in advance for enabling the first instruction to be triggered in a state where the transparent mask layer completely covers the screen. The first instruction is for "unlocking" the transparent mask layer. The specific unlocking method is to reduce the transparent mask layer to a specified size, such as to reduce the size of one pixel. Therefore, the thread of the transparent mask layer can be prevented from being recycled by the system, the quick start again is facilitated, and the state of completely covering the screen is recovered, namely the screen is locked again.
Meanwhile, a key for triggering the second instruction in a state of "unlocking" the transparent mask layer is also specified in advance. And the second instruction is used for restoring the state that the transparent mask layer completely covers the screen, namely restoring the state from the unlocking state to the screen locking state.
Optionally, the designated key for triggering the second instruction may also be a key for triggering the first instruction directly, that is, only one key is designated for triggering the first instruction and the second instruction. The trigger conditions of the two instructions correspond to different states respectively, so that the control is not confused, and the control is convenient. Of course, different keys may be set, depending on the requirements.
The implementation mode can be as follows: under the state of carrying out screen locking through the transparent mask layer, a first instruction can be triggered through a designated key of the terminal, and the transparent mask layer is reduced to a pixel point size (at the moment, the thread of the transparent mask layer is not recycled by the system, but is in a dormant state, so that the realization of screen locking again can be ensured). And then, all touch instructions controlled by the terminal application by the user are not intercepted any more, and are transmitted to the upper layer application for analysis processing as usual.
And then, if the screen locking state is required to be recovered through the transparent mask layer, the transparent mask layer thread can be awakened only by triggering a second instruction through the appointed key, and the transparent mask layer completely covers the terminal screen again.
When the first instruction and the second instruction are triggered, the same appointed key is adopted. Optionally, when the first instruction is triggered by the designated key and the transparent mask layer is reduced, the transparent mask layer can be maintained in a reduced state by pressing the designated key for a long time; after the appointed key is released (namely when the pressing signal of the appointed key cannot be received), a second instruction is triggered, and the transparent mask layer is immediately restored to the original unlocking mode and the original restoring mode for control. Optionally, whether the trigger is the first instruction or the second instruction may also be determined in accordance with the operation sequence. If the first instruction is triggered by the appointed key for the first time, and then the second instruction is triggered by the appointed key, the 'unlocking' or 'restoring' operation is determined.
Optionally, the manner of triggering the first instruction by the designated key may be that the designated key is pressed for n seconds (n ≧ 2s), for example, the transparent mask layer automatically shrinks after the designated key is pressed for 2 s. The possibility of mistaken touch is avoided again in a delayed touch response mode, and the control effectiveness is improved. Of course, the first instruction can be triggered in a mode of continuously pressing the designated key for N times (N is larger than or equal to 2), and the possibility of mistaken touch can be avoided through a precise control mode.
Correspondingly, the mode of triggering the second instruction by the designated key may also be the delayed touch response mode or the continuous press triggering mode.
Optionally, the designated key is located at the back of the terminal or at the bottom of the side edge or the front surface. Preferably behind the terminal, such as a fingerprint key behind which a particular terminal (e.g., a gorgeous series) is located, which facilitates in-the-dark aiming and manipulation.
Particularly, as shown in fig. 2, the terminal projects a touch trajectory and a touch position corresponding to an operation after the user is "unlocked" into the head-mounted device in real time, so that the user can clearly identify the touch position of the user, thereby facilitating interaction.
Specifically, when in operation, the current touch position is located on the screen of the head-mounted device through a cross or a dot, and the horizontal and vertical positions are displayed in opposite colors on the frame, which can be embodied in a coordinate form; in addition, the track that the touch passes will also be displayed using the opposite color, and the current position of the finger touch will be displayed using the circle. Therefore, the user can conveniently and accurately touch. The display in the opposite color, namely the color opposite to the original pixel display of the current screen, can avoid the same color from being unclear.
Example two
This embodiment provides a specific application scenario corresponding to the first embodiment: the user connects with the mobile phone through the head-mounted device (similar to *** glasses, but no operating system is arranged in the glasses, and all display contents are projected into the head-mounted device through the hdmi screen by the mobile phone), and the video played on the mobile phone is watched through the head-mounted device so as to obtain a better film watching effect. But in the process, the mobile phone needs to keep bright screen to ensure that the mobile phone and the head-mounted device can play normally. If the mobile phone screen is locked and put into a pocket, the screen is blacked, and the content on the head-mounted equipment is not displayed; if the screen is not locked and the screen is put into a pocket, the mistaken touch is easy to generate. By using the method provided by the first embodiment, the transparent mask layer is displayed on the screen of the mobile phone, so that the mobile phone can be put into a pocket or a bag to continue to keep video playing (namely, screen-on), and error touch is effectively prevented.
After the transparent mask layer is enabled, all operations through a normal touch screen are intercepted by the mask layer and are not transmitted to the video app. Meanwhile, the brightness of the mobile phone is adjusted to be darkest so as to save electric quantity, and the brightness of the mobile phone does not influence the film watching effect of the head-mounted equipment because the head-mounted equipment is provided with an independent brightness adjusting function.
The user presses a button on the back of the mobile phone by a forefinger for 2 seconds and then automatically releases the screen locking (the transparent shielding layer automatically reduces the window into 1 pixel point, and the touch event can automatically and directly transmit the upper application); through touch control of the thumb on the screen, the touch event can be directly transmitted to the video app, and automatic unlocking in the pocket and app operation are achieved. In addition, the finger ring is matched, so that the forefinger cannot be loosened because the thumb leaves the screen when pressing the back button.
When the index finger of the user is released (the mobile phone receives a key-up signal), the transparent window of the shade can be paved on the whole screen again.
When the combined operation is used, a cross positioning line is drawn on the screen of the head-mounted device by using the central point of the touch position, the horizontal position and the vertical position are displayed in opposite colors of the frame, the track which is touched to pass is displayed in the opposite colors, and the current position of the finger touch is displayed by using the circle. Therefore, the user can clearly see the position touched by the user, and therefore, the user can operate and make the required gesture operation.

The detailed steps are not repeated here, and refer to the description of the first embodiment or the second embodiment in detail.
In summary, the screen locking method and the storage medium for the terminal connected with the head-mounted device provided by the invention can maintain normal playing of the head-mounted device and effectively prevent mistaken touch; furthermore, the terminal can be conveniently and accurately controlled in the dark to interact with the app; furthermore, the electric quantity of the terminal can be saved.
