Embodiment 1

[0028] see figure 1 , which is a schematic flowchart of an interface switching method provided by an embodiment of the present invention.

[0029] The interface switching method is applied to terminal equipment, and the switching method includes:

[0030] In step S101, a vibration signal is received.

[0031] It can be understood that the vibration signal is usually generated by a tapping action, and the tapping object includes but is not limited to: tapping the display screen, casing, side of the terminal device, and external devices, such as: earphones , mobile phone case, etc. Moreover, the tapping action may be directly with a finger, or through an auxiliary object such as a stylus or a key.

[0032] In step S102, the vibration signal is generated into a vibration audio signal through a microphone.

[0033] The invention uses a microphone to identify the tapping action, and receives and records the vibration signal generated by the tapping action in a recording manner ...

Embodiment 2

[0048] see figure 2 , which is a schematic flowchart of an interface switching method provided by an embodiment of the present invention.

[0049] The interface switching method is applied to terminal equipment, and the switching method includes:

[0050] In step S201, the terminal device receives a vibration signal generated by knocking.

[0051] It can be understood that the vibration signal is usually generated by a tapping action, and the tapping object includes but is not limited to: tapping the display screen, casing, side of the terminal device, and external devices, such as: earphones , mobile phone case, etc.

[0052] In step S202, the vibration signal is identified by a microphone to generate a vibration audio signal.

[0053] In step S203, it is judged whether the microphone is an analog microphone, wherein the attribute of the vibration audio signal generated by the analog microphone is an analog signal.

[0054] Wherein, if it is an analog microphone, execute...

Embodiment 3

[0084] see image 3 , is a block diagram of the interface switching system provided by the embodiment of the present invention. The interface switching system is applied to a terminal device.

[0085] The interface switching system 300 includes: a receiving module 31 , a microphone module 32 , a frequency domain module 33 , a switching judgment module 34 , a switching execution module 35 , and other execution modules 36 .

[0086] Specifically, the receiving module 31 is configured to receive vibration signals.

[0087] It can be understood that the vibration signal is usually generated by a tapping action, and the tapping object includes but is not limited to: tapping the display screen, casing, side of the terminal device, and external devices, such as: earphones , mobile phone case, etc. Moreover, the tapping action may be directly with a finger, or through an auxiliary object such as a stylus or a key.

[0088] The microphone module 32 is connected to the receiving mod...

Abstract

The invention provides an interface switching method and switching system. The interface switching method comprises the following steps: receiving a vibration signal; through a microphone, generating the vibration signal into a vibration voice frequency signal; carrying out Fourier transform on the vibration voice frequency signal to carry out frequency domain analysis, wherein the frequency domain comprises time, frequency and / or amplitude; through the frequency domain, judging whether the vibration signal is a switching instruction or not; and if the vibration signal is the switching instruction, switching a first interface to a second interface. Through the build-in microphone of terminal equipment, the vibration signal generated by knocking is generated into the vibration voice frequency signal, the switching instruction is further filtered for switching the interfaces, an additional sensor does not need to be added, the weight of the terminal equipment is not affected, production cost is saved, and meanwhile, the interface switching method has the advantages of being convenient in operation and high in identification rate.

Description

technical field [0001] The invention belongs to the field of human-machine interfaces of terminal equipment, and in particular relates to an interface switching method and switching system. Background technique [0002] With the popularity of smart terminal equipment, it has brought great convenience to users' work and life. [0003] In recent years, manufacturers of smart terminals are not satisfied with receiving user operations through designated buttons, but are committed to expanding the human-machine interface, such as: replacing the triggering of designated buttons by gestures, pressing, shaking, etc., so that smart Terminal equipment can be adapted to various types of scenarios. [0004] However, the existing methods of replacing designated keys with man-machine interfaces require adding additional sensors, such as adding capacitance, pressure sensors, acceleration sensors, etc. to the display to sense gestures, pressing, or shaking, etc. The operation instruction ...
