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

[0069] Please refer to figure 1 with figure 2 , this embodiment provides an audio-based terminal screen control method. 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.

[0070] The methods include:

[0071] First, when the terminal microphone receives a specific frequency sound sequence from its speaker whose amplitude is higher than the threshold, set the mask layer (display) on the top layer of all applications in the terminal; and intercept all touch events of the terminal through the mask layer.

[0072] The setting of the mask layer can realize the "false lock screen" effect that the terminal can still play the original app content, and the headset connected to it can still play the terminal display content normally, but cannot touch the terminal. Wherein, the interception method may be to intercept all touch events and not pass them to the ...

Embodiment corresponding Embodiment 1

[0091] This embodiment corresponds to Embodiment 1, and provides a specific application scenario:

[0092] The user connects to the mobile phone through a headset (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 headset through hdmi), and uses the headset to watch what is being played on the phone. Video for a better viewing experience. 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. And utilize the method that embodiment 1 provides, just can display transparent cover layer on the screen of mobile phone, make mobile phone put ...

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 implement the above-mentioned embodiment 1 or Embodiment 2. The steps included in an audio-based terminal screen control method. 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 audio-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 false touches; furthermore, it can also support convenient and accurate Secretly control the terminal and interact with the app; furthermore, it can also save the power of the terminal.

Abstract

The invention provides an audio-based terminal screen control method and a storage medium, and the method comprises the steps: setting a mask layer at the uppermost layer of all applications of a terminal when a terminal microphone receives a specific-frequency sound sequence, with the amplitude higher than a threshold value, emitted by a loudspeaker of the terminal microphone; intercepting all touch events of the terminal through the mask layer; and when the amplitude of the specific frequency sound sequence received by the terminal microphone is lower than a threshold value, reducing the mask layer to a specified size. According to the invention, normal playing of the head-mounted equipment can be maintained, and mistaken touch can be effectively prevented; furthermore, the terminal canbe conveniently and accurately controlled in the dark to interact with the app; furthermore, the electric quantity of the terminal can be saved.

Description

technical field [0001] The invention relates to the field of head-mounted devices, in particular to an audio-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 an audio-based terminal screen control method and a storage medium, which can...
