Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The invention provides a display method for a display terminal interface.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for displaying a terminal interface according to an embodiment of the present invention.
For convenience of explanation and understanding of the display method of the display terminal interface according to the present invention, the following embodiment will explain the display method of the display terminal interface according to the present invention in detail by taking a mobile phone as an example.
In this embodiment, the display method for the display terminal interface includes the following steps:
s0: establishing a coordinate system of a touch screen of the display terminal, taking the lower left as a touch origin, namely (0, 0) point, and the upper right as a maximum resolution point of the touch screen of the mobile phone, namely (X _ max, Y _ max); an unlocking area is preset on the touch screen;
specifically, in the method for displaying the terminal interface according to the embodiment, a coordinate system of a touch screen (a mobile phone touch screen) of the display terminal is established, where the lower left is taken as a touch origin, that is, a (0, 0) point, and the upper right is taken as a maximum resolution point of the mobile phone touch screen, that is, an (X _ max, Y _ max). After the coordinate system is established, each pixel point on the mobile phone touch screen has a corresponding coordinate value (Xn, Yn); step S0 is to set up a coordinate system for the touch screen of the mobile phone and to preset an unlock area on the touch screen. According to the habit of holding the mobile phone by one hand of the user, the area which is easy to touch by the thumb is the middle-lower area of the touch screen, and the 2/3 area at the lower part of the touch screen of the mobile phone is set as the unlocking area in the embodiment. Fig. 2 is a schematic diagram of a preset unlocking area in the display terminal interface display method of the present invention. In this embodiment, an 2/3 area at the lower part of the touch screen 200 of the mobile phone is set as an unlocking area 201, and a horizontal unlocking bar 202 and a word 203 of "unlocking with one hand" are further disposed in the preset unlocking area 201, so as to guide a user to unlock the mobile phone by drawing a horizontal line according to a guide track of the horizontal unlocking bar 203 when the user operates the mobile phone with one hand.
Step S1: detecting a touch operation instruction in a preset unlocking area on the display terminal;
step S2: acquiring coordinate information of the current touch point every other preset time period according to the touch operation instruction;
specifically, in this embodiment, when a touch operation instruction in a preset unlocking region on a touch screen of a mobile phone is detected, coordinate information of a current touch point is acquired every preset time period according to the detected touch operation instruction. In this embodiment, the preset time period t is 50ms, that is, the coordinate information of the touch point is acquired every 50 ms. For example, the initial touch time is T0, the initial touch point is a1 point, the coordinate corresponding to a1 point is (X1, Y1), then coordinate information of the touch point is acquired every 50ms, that is, the coordinate of the touch point a2 (i.e., the second touch point) acquired at T0+ T is (X2, Y2), the coordinate of the touch point A3 (i.e., the third touch point) acquired at T0+2T is (X3, Y3), and so on, the coordinate information of the fourth touch point a4 to the nth touch point An is acquired. That is, the coordinate information acquired in step S2 are a1(X1, Y1), a2(X2, Y2), A3(X3, Y3), a4(X4, Y4), … … An (Xn, Yn), respectively.
Step S3: judging the track direction of the sliding track of the touch point according to the obtained abscissa value in the coordinate information;
specifically, in the present embodiment, the track direction of the sliding track of the touch point is determined according to the abscissa value in the coordinate information obtained in step S2, that is, the track direction of the sliding track of the touch point is determined according to the abscissa values X1, X2, X3, X4, and … … Xn of the coordinate information a1(X1, Y1), a2(X2, Y2), A3(X3, Y3), a4(X4, Y4), and … … An (Xn, Yn) obtained in step S2.
When the user operates the mobile phone with one hand, the common habit is that the thumb is used for operating the mobile phone touch screen, when the thumb draws a transverse line on the touch screen for unlocking, the thumb usually slides from the outer side to the inner side, so that whether the user operates the mobile phone with the left hand or the right hand can be identified through the track direction (sliding from left to right or sliding from right to left) of the sliding track of the thumb, that is, the track direction of the sliding track of the touch point can be judged according to the transverse coordinate value in the coordinate information acquired in the step S2, and then whether the user operates the mobile phone with the left hand or the mobile phone with the right hand can be identified according to the track direction of the sliding track of the touch point.
Specifically, if the difference values of the abscissa values in the coordinate information acquired in step S2 twice before and after are both greater than 0, it may be determined that the trajectory direction of the sliding trajectory of the touch point is sliding from right to left, i.e., if X1-X2>0 and X2-X3>0 and X3-X4>0 … … and Xn-X (n-1) >0 (i.e., X1> X2> X3> X4> … … > Xn), it may be determined that the trajectory direction of the sliding trajectory of the touch point is sliding from right to left; and when the track direction of the sliding track of the touch point is judged to be sliding from right to left, the user operates the mobile phone with the left hand at the moment.

further, in this embodiment, if the difference between the abscissa values in the coordinate information obtained in two previous and subsequent times in step S2 is not equal to or greater than 0, and a case equal to 0 occurs (i.e., the difference between the abscissa values in the coordinate information obtained in two previous and subsequent times is equal to or greater than 0), which indicates that the user touches the same point of the unlock region twice), for example, X1> X2 ═ X3> X4 … … > Xn (i.e., the second touch point and the third touch point are the same point), X1> X2> X3 ═ X4 … … > Xn (i.e., the third touch point and the fourth touch point are the same point), or X1 ═ X2> X3> X4 … … > Xn (i.e., the first touch point and the second touch point are the same point), and so on, this embodiment may also determine that the trajectory direction of the sliding trajectory of the touch point is sliding from right;
if the difference values of the abscissa values in the coordinate information acquired in the step S2 two times before and after are both less than 0, it may be determined that the trajectory direction of the sliding trajectory of the touch point is sliding from left to right, i.e., if X1-X2 < 0 and X2-X3 < 0 and X3-X4 < 0 and …, and Xn-X (n-1) < 0 (i.e., X1 < X2 < X3 < X4 < … < Xn), it may be determined that the trajectory direction of the sliding trajectory of the touch point is sliding from left to right. And when the track direction of the sliding track of the touch point is judged to be sliding from left to right, indicating that the user operates the mobile phone by the right hand at the moment. Fig. 4 shows a schematic diagram of corresponding sliding tracks when a user operates a mobile phone with a right hand, in fig. 4, a start touch point D1 of the sliding track 401, a start touch point E1 of the sliding track 402, and a start touch point F1 of the sliding track 403 are all located on the left side of the mobile phone touch screen, an end touch point Dn of the sliding track 401, an end touch point En of the sliding track 402, and an end touch point Fn of the sliding track 403 are all located on the right side of the mobile phone touch screen, that is, the track directions of the sliding track 401, the sliding track 402, and the sliding track 403 are all sliding from left to right, that is, the sliding track 401, the sliding track 402, and the sliding track 403 in fig. 4 all represent that the user operates the mobile phone with a right hand;
further, in this embodiment, if the difference between the abscissa values in the coordinate information obtained in two previous and subsequent times in step S2 is not equal to 0, and a case equal to 0 occurs (i.e., the difference between the abscissa values in the coordinate information obtained in two previous and subsequent times is equal to 0), which indicates that the user touches the same point of the unlock region twice), for example, X1 < X2 ═ X3 < X4 … … < Xn (i.e., the second touch point and the third touch point are the same point), X1 < X2 < X3 ═ X4 … … < Xn (i.e., the third touch point and the fourth touch point are the same point), or X1 ═ X2 < X3 < X4 … … < Xn (i.e., the first touch point and the second touch point are the same point), and the like, this embodiment may also determine that the trajectory direction of the sliding trajectory of the touch point is sliding from left to right.
In addition, in this embodiment, if the difference between the abscissa values in the coordinate information acquired in step S2 twice before and after is equal to 0, which indicates that the thumb of the user is not slipping, that is, if X1 is X2 is X3 is X4 … … is Xn, the trajectory direction of the sliding trajectory of the touch point cannot be determined.
Step S4: controlling the display terminal to enter a preset user operation interface mode according to the track direction; the user operation interface mode includes a left hand operation interface mode and a right hand operation interface mode.
Specifically, after entering the unlocking state according to the sliding track, if it is determined in step S3 that the track direction of the sliding track of the touch point slides from right to left, the display terminal is controlled to enter a preset left-handed operation interface mode; and if the step S3 determines that the trajectory direction of the sliding trajectory of the touch point is sliding from left to right, controlling the display terminal to enter a preset right-hand operation interface mode.
In addition, before step S3, the present embodiment further includes the following steps:
s21: and calculating the slope of the connecting line between the current touch point and the initial touch point according to the acquired coordinate information of the current touch point and the coordinate information of the initial touch point, and turning to the step S3 if the absolute value of the slope is less than or equal to 1.
Specifically, in order to ensure that the respective slide tracks in fig. 3 and 4 do not deviate too much from the bar shown in fig. 2, the slope of the line connecting the respective touch points on the respective slide tracks and the start touch point (X1, Y1) is limited within a certain range, and in this embodiment, the absolute value of the slope is 1 or less (i.e., -1< (Yn-Y1)/(Xn-X1) <1, where n is a positive integer of 2 or more). That is, in this embodiment, after the coordinate information of each touch point is acquired every preset time period in step S2, the slope of the connection line between each touch point on the sliding track and the start touch point (X1, Y1) is respectively calculated, and if the absolute value of the slope is less than or equal to 1, the step S3 is performed.
The method for displaying the interface of the display terminal provided by the embodiment includes the steps that firstly, a coordinate system of a touch screen of the display terminal is established, a touch origin point, namely a (0, 0) point, is arranged at the lower left, and a maximum resolution point, namely (X _ max and Y _ max), of the touch screen is arranged at the upper right; an unlocking area is preset on the touch screen; then, detecting a touch operation instruction in a preset unlocking area on the display terminal; then, acquiring coordinate information of the current touch point every other preset time period according to the touch operation instruction; then, judging the track direction of the sliding track of the touch point according to the abscissa value in the obtained coordinate information; and finally, entering an unlocking state according to the sliding track, and controlling the display terminal to enter a preset left-hand operation interface mode or a preset right-hand operation interface mode according to the track direction. The display terminal interface display method provided by the embodiment can control the display terminal to enter a preset left-hand operation interface mode or a preset right-hand operation interface mode according to the track direction of the sliding track of the touch point in the preset unlocking area on the display terminal by the user, so that the user can conveniently operate all controls on the touch screen of the display terminal by one hand.

According to the habit of holding the mobile phone by one hand of the user, the area which is easily touched by the thumb is the middle-lower area of the touch screen, so in this embodiment, the preset module 501 sets the 2/3 area at the lower part of the touch screen of the mobile phone as the unlocking area.

When a user operates a mobile phone with one hand, the common habit is that a thumb is used for operating a mobile phone touch screen, and when the thumb draws a transverse line on the touch screen for unlocking, the thumb usually slides from the outer side to the inner side, so that whether the user operates the mobile phone with the left hand or the right hand can be identified through the track direction of the sliding track of the thumb (sliding from left to right or sliding from right to left), that is, the judgment module 504 can judge the track direction of the sliding track of the touch point according to the transverse coordinate value in the coordinate information acquired by the information acquisition module 503, and then can identify whether the user operates the mobile phone with the left hand or the mobile phone with the right hand according to the track direction of the sliding track of the touch point.

Specifically, in order to ensure that the slide trajectory does not deviate too much from the unlock guide trajectory (i.e., the crossline unlock bar), the slope of the line connecting each touch point on the slide trajectory and the start touch point (X1, Y1) is limited within a certain range, and in the present embodiment, the absolute value of the slope is 1 or less (i.e., -1< (Yn-Y1)/(Xn-X1) <1, where n is a positive integer of 2 or more). That is, after the information obtaining module 503 obtains the coordinate information of each touch point every preset time period, the calculating module 506 calculates the slope of the connection line between each touch point on the sliding track and the initial touch point (X1, Y1); then, the determining module 504 determines whether the slope is less than or equal to 1, and if the slope is less than or equal to 1, the determining module 504 determines the track direction of the sliding track of the touch point according to the abscissa value in the coordinate information acquired by the information acquiring module 503.
It should be noted that, the absolute value of the slope being less than or equal to 1 is only a preferred embodiment of the present invention, and when the absolute value of the slope is in other ranges, for example, if the absolute value of the slope is greater than 1 (i.e., (Yn-Y1)/(Xn-X1) < -1 or (Yn-Y1)/(Xn-X1) > 1, where n is a positive integer greater than or equal to 2), the determining module 504 may also determine the track direction of the sliding track of the touch point according to the abscissa value in the coordinate information acquired by the information acquiring module 503.
In the display device for displaying the interface of the display terminal provided by this embodiment, first, the preset module establishes a coordinate system of the touch screen of the display terminal, and takes the lower left as a touch origin, that is, a (0, 0) point, and the upper right as a maximum resolution point of the touch screen, that is, an (X _ max, Y _ max); an unlocking area is preset on the touch screen; then, the detection module detects a touch operation instruction in a preset unlocking area on the display terminal; then, the information acquisition module acquires coordinate information of the current touch point every other preset time period according to the touch operation instruction; then, the calculation module calculates the slope of a connecting line between each touch point and the initial touch point according to the coordinate information of each touch point and the coordinate information of the initial touch point acquired by the information acquisition module, and if the absolute value of the slope is less than or equal to 1, the judgment module judges the track direction of the sliding track of the touch point according to the abscissa value in the acquired coordinate information; and finally, the processing module controls the display terminal to enter a preset left-hand user operation interface mode or a preset right-hand user operation interface mode according to the track direction. The display terminal interface display device provided by the embodiment can control the display terminal to enter a preset left-hand operation interface mode or a preset right-hand operation interface mode according to the track direction of the sliding track of the touch point in the preset unlocking area on the display terminal by the user, so that the user can conveniently operate all controls on the touch screen of the display terminal by one hand.
