Problems solved by technology

Based on the current technology, if the terminal is locked, it will not be able to continue outputting images to the headset
However, if the terminal does not lock the screen, accidental touches are prone to occur, especially when it is placed in a pocket; and when the terminal (such as a mobile phone) is placed in the pocket and the screen is locked, it is difficult to operate the terminal, and thus cannot control the head-mounted device. display of

Embodiment 1

[0072] Please refer to figure 1 and figure 2 , this embodiment provides a terminal screen control method based on fingerprint recognition. For a terminal with fingerprint recognition function, when the terminal is stored, it can still ensure that the head-mounted device plays or displays the content of the terminal screen normally, and can also realize secret control.

[0073] The methods include:

[0074] First, set the mask layer (display) on top of all applications in the terminal. Optionally, the mask layer may be a transparent mask layer, or may be a customized interface style. In this embodiment, a transparent mask layer is taken as an example for illustration.

[0075] All touch events are intercepted through the transparent mask layer, so that the terminal can still play the original app content, and the connected headset can still play the terminal display content normally, but the "false lock screen" effect that the terminal cannot be touched.

[0076] Wherein, ...

Embodiment 2

[0091] This embodiment corresponds to Embodiment 1, and provides a specific application scenario: the user uses a head-mounted device (a device similar to Google Glass, but there is no built-in operating system in the glasses, and all displayed content is projected from the mobile phone to the head-mounted device through hdmi ) to connect to a mobile phone with fingerprint recognition function, and use the headset to watch the video being played on the mobile phone to obtain a better viewing effect. However, the mobile phone needs to keep the screen bright during the process to ensure that both the mobile phone and the headset can play normally. If the mobile phone lock screen is put in the pocket, the screen will be black, and the content on the headset will not be displayed; if the mobile phone is not locked and the screen is put in the pocket, it is easy to cause accidental touches. With the method provided in Embodiment 1, by displaying a transparent mask layer on the scre...

Embodiment 3

[0098] This embodiment corresponds to Embodiment 1 or Embodiment 2, and provides a computer-readable storage medium on which a computer program is stored. When the program is executed by a processor, it can realize the above-mentioned embodiment 1 or Embodiment 2. The steps included in a terminal screen control method based on fingerprint identification. The specific steps will not be repeated here, please refer to the description of Embodiment 1 or Embodiment 2 for details.

[0099] To sum up, the fingerprint identification-based terminal screen control method and storage medium provided by the present invention can not only maintain the normal playback of the head-mounted device, but also effectively prevent accidental touches; further, directly use the fingerprint to unlock and lock the screen, The operation is convenient and the implementation cost is low; further, it can also support convenient and accurate manipulation of the terminal in the dark, and interact with the a...

Abstract

The present invention provides a terminal screen control method and storage medium based on fingerprint identification. The method includes: setting a mask layer on the top layer of all terminal applications; intercepting all touch events of the terminal through the mask layer; if the terminal recognizes the fingerprint, And if the identification is passed, the mask layer is reduced to a specified size; when the terminal cannot recognize the fingerprint, the mask layer is restored to its original state. The present invention can not only maintain the normal playback of the head-mounted device, but also effectively prevent accidental touches; further, directly use the fingerprint to unlock and lock the screen, which is convenient to operate and low in implementation cost; further, it can also support convenient and accurate control in the dark The terminal interacts with the app; furthermore, it can also save terminal power.

Description

technical field [0001] The invention relates to the field of head-mounted devices, in particular to a fingerprint identification-based terminal screen control method and a storage medium. Background technique [0002] More and more head-mounted devices support outputting screens of terminals (mobile phones, tablets, etc.) to the head-mounted devices for display. Based on the current technology, if the terminal is locked, it will not be able to continue outputting images to the headset. However, if the terminal does not lock the screen, accidental touches are prone to occur, especially when it is placed in a pocket; and when the terminal (such as a mobile phone) is placed in the pocket and the screen is locked, it is difficult to operate the terminal, and thus cannot control the head-mounted device. display. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a terminal screen control method and storage medium based...
