Currently, a method for calculating position and time information uses three satellites and corrects an error of the calculated position and time information by using another satellite. In addition, the GPS unit 115 can calculate speed information by continuously calculating current position information in real time.
The a/V input unit 120 is used to receive an audio or video signal. The a/V input unit 120 may include a camera 121 and a microphone 1220, and the camera 121 processes image data of still pictures or video obtained by an image capturing apparatus in a video capturing mode or an image capturing mode.

The image frames processed by the cameras 121 may be stored in the memory 160 (or other storage medium) or transmitted via the wireless communication unit 110, and two or more cameras 121 may be provided according to the construction of the mobile terminal. The microphone s122 can receive sounds (audio data) via the microphone in a phone call mode, a recording mode, a voice recognition mode, or the like, and can process such sounds into audio data. The processed audio (voice) data may be converted into a format output transmittable to a mobile communication base station via the mobile communication unit 112 in case of the phone call mode. The microphone 122 may implement various types of noise cancellation (or suppression) algorithms to cancel (or suppress) noise or interference generated in the course of receiving and transmitting audio signals.
The user input unit 130 may generate key input data according to a command input by a user to control various operations of the mobile terminal.

In particular, when the touch pad is superimposed on the display unit 151 in the form of a layer, a touch screen may be formed.

For example, when the mobile terminal 100 is implemented as a slide-type mobile phone, the sensing unit 140 may sense whether the slide-type phone is opened or closed. In addition, the sensing unit 140 can detect whether the power supply unit 190 supplies power or whether the interface unit 170 is coupled with an external device. The sensing unit 140 may include a light sensor 141.
The interface unit 170 serves as an interface through which at least one external device is connected to the mobile terminal 100.

The identification unit may store various information for authenticating a user using the mobile terminal 100 and may include a user identity Unit (UIM), a subscriber identity unit (SIM), a universal subscriber identity Unit (USIM), and the like. In addition, a device having an identification unit (hereinafter, referred to as an "identification device") may take the form of a smart card, and thus, the identification device may be connected with the mobile terminal 100 via a port or other connection means. The interface unit 170 may be used to receive input (e.g., data information, power, etc.) from an external device and transmit the received input to one or more elements within the mobile terminal 100 or may be used to transmit data between the mobile terminal and the external device.
In addition, when the mobile terminal 100 is connected with an external cradle, the interface unit 170 may serve as a path through which power is supplied from the cradle to the mobile terminal 100 or may serve as a path through which various command signals input from the cradle are transmitted to the mobile terminal.

Up to this point, mobile terminals have been described in terms of their functionality. Hereinafter, a slide-type mobile terminal among various types of mobile terminals, such as a folder-type, bar-type, swing-type, slide-type mobile terminal, and the like, will be described as an example for the sake of brevity. Accordingly, the present invention can be applied to any type of mobile terminal, and is not limited to a slide type mobile terminal.
The mobile terminal 100 as shown in fig. 1 may be configured to operate with communication systems such as wired and wireless communication systems and satellite-based communication systems that transmit data via frames or packets.
The following is a detailed description of specific examples.
First embodiment
Referring to fig. 2, fig. 2 is a schematic diagram of a terminal screen unlocking device module according to a first embodiment of the present invention.
The terminal screen unlocking device in the embodiment comprises:
the acquisition module 201 is configured to acquire displacement motion parameters corresponding to different outer surfaces through at least two capacitive displacement sensors arranged in different outer surfaces of the terminal in a screen locking state, where the displacement motion includes: a displacement motion perpendicular to the terminal surface and a displacement motion at the terminal surface and closely above the surface;
and the unlocking module 202 is used for unlocking the terminal screen when the displacement motion parameter meets a preset unlocking displacement motion parameter.
In the screen locking state in this embodiment, the terminal is at least in the screen off state, and the screen is not lighted, but when the screen just enters the screen off state, generally within 1 to 2 seconds, the terminal does not really enter the screen locking state, and the user can use the terminal normally again without unlocking operation.
A capacitive displacement sensor, which may also be referred to as a capacitive proximity sensor, or a capacitive proximity switch, etc., and which may be referred to as a sensor in this embodiment, is disposed in the terminal; as shown in fig. 6, in an embodiment, it can be determined whether an object is close to the sensor and the degree of proximity, such as far, near, light, heavy, etc., according to the detected capacitance value C of the sensor; the method comprises the following specific steps:
as can be seen from the capacitance calculation formula C ═ S/d:
in the scenario shown in fig. 6a, no finger of the user approaches the sensor, and the distance d between the two plates of the sensor is infinite, where the capacitance C is 0;
in the scenario shown in fig. 6b, a user 'S finger approaches the sensor, the user' S finger serves as one of the plates of the capacitor, at this time, the distance d between the two plates is small, and at this time, the capacitance value C ═ S)/d is greater than 0; therefore, whether a finger is close can be determined according to whether the capacitance value exists; for example, it is foreseeable that when the terminal is in a holding state, the sensor on the side of the terminal is generally pressed and contacted by the finger and the palm of the user, so the trigger capacitance value of the sensor on the side of the terminal can be set to a larger value, and correspondingly, the trigger capacitance values of the sensors on other parts of the terminal can be set to a smaller value, which is convenient for the user to operate.
In the scenario shown in fig. 6C, a user 'S finger lightly presses on the sensor, the user' S finger serves as one of the plates, and a distance D between the two plates is a distance from the sensor to an outer shell of the terminal, that is, a thickness D of the outer shell of the terminal, where a capacitance value C is (S)/D; because the user lightly presses, the contact area S between the two polar plates is smaller, and the capacitance value is smaller;
in the scenario shown in fig. 6D, the user 'S finger presses hard on the sensor, the user' S finger serves as one of the plates, the distance D between the two plates is the thickness D of the terminal shell, and the capacitance C is (S)/D; because the user presses heavily, the contact area S between the two polar plates is larger, and the capacitance value is larger; that is, the degree of user pressing (light pressing or heavy pressing) may be determined according to the magnitude of the capacitance value.
Based on the analysis, the touch screen can detect parameters such as sliding, pressing and pressing size (force) of a user on the surface of a terminal such as a mobile phone based on the capacitive displacement sensor. It should be noted that the capacitive motion displacement sensor is characterized in that it can detect objects of any material, including living bodies including human bodies, or inorganic substances, etc., and the finger part of a person is commonly used, and most users use fingers to operate the terminal.
In this embodiment, as shown in fig. 9, a plurality of sensors are provided in the terminal, and mainly include:
the sensors are arranged on the side surface of the terminal in the length direction, wherein the sensors have at least one row and can have two or more rows; in a general arrangement, the sensor on the side of the terminal is divided into two ends, and the upper part and the lower part of the side of the terminal are the center of gravity of the arrangement, because the user has long fingers in these positions during the operation of the terminal, for example, when the user holds the terminal in a vertical screen, the lower part of the side of the terminal is always in a held state. Since the side portion is formed in a long and narrow shape, and is highly adaptable to detection of displacement motion in the longitudinal direction, the sensor provided at the side portion of the terminal is mainly used for monitoring operations such as pressing, linear sliding, and the like of the user. Of course, the sensor provided at the side of the terminal can still detect the sliding, pressing (clicking), or other displacement motion in the width direction of the user.
The sensor is arranged on the back of the terminal, wherein the upper part and the lower part of the back are the gravity centers of the back arranged sensor, also because the movement of the fingers on these parts is convenient for the user during the operation of the terminal. Because the area of the back of the terminal is larger, the number and the area of the arranged sensors can also be larger, and a plurality of sensors can be arranged to form a matrix as shown in fig. 9; these sensors may be used to detect user presses, linear slides, track slides, and the like.
The sensors in different outer surfaces refer to sensors arranged on two side surfaces and a back surface of the terminal, and at least comprise different outer surfaces, which can be sensors arranged on the side surfaces and the back surface, or sensors arranged on the two side surfaces.
On the basis, the preset unlocking displacement motion parameters comprise: presetting the motion types of the surfaces, presetting the time sequences of the motion of different surfaces and presetting the displacement motion parameters of the surfaces. The motion type of the preset surface refers to that on a specific surface, a sensor detects pressing, linear sliding, track sliding and other operations of a user; the preset time sequence of the motions of different surfaces means the time sequence between the motions of different surfaces.
Wherein, the displacement motion parameters of the preset surface are as follows:
in this embodiment, when the preset unlocking displacement motion parameter is a linear sliding motion parameter, the displacement motion parameter may include at least one of a linear sliding direction, a linear sliding length, a speed of linear sliding, and the like. Referring to fig. 7, fig. 7 shows a situation of obtaining a displacement motion parameter when the unlocking displacement motion parameter is a linear sliding motion parameter. At time T1, sensor 1 is detected to be pressed, and at time T2, sensor 2 is detected to be pressed, then:
the linear sliding direction is: the position corresponding to the sensor 1 is changed to the position corresponding to the sensor 2;
the linear sliding length is: a distance length L1 from the position corresponding to sensor 1 to the position corresponding to sensor 2;
