Fig. 1 is a schematic flow chart of a font size control method based on an intelligent terminal in a preferred embodiment of the present invention. In this embodiment, the font size control method specifically includes the following steps:
s100: detecting the number of contacts simultaneously received by a display interface of the intelligent terminal, and when the number of the contacts is two, detecting the pressure of the two contacts on the display interface and/or the duration of continuous contact of the two contacts with the display interface
To implement zooming of text content, a trigger event needs to be set first to prevent the user experience from being reduced due to misoperation of the user. The method comprises the steps of firstly detecting the number of touch points simultaneously received by a display interface of the intelligent terminal, wherein the number of touch points is the number of positions where touch screen events occur at different positions of the display interface by a user, and when the situation that the display interface simultaneously receives 2 touch points is detected, the user is considered to possibly zoom in and out a text. The trigger event may be that the user presses the screen for more than a certain pressure, or the user touches the screen for more than a certain duration, or the two conditions are in a logical or relationship, where the user presses the screen for more than a certain pressure or the user touches the screen for more than a certain duration to trigger the text zooming operation, either one of the two conditions may be selected, or the two conditions are in a logical and relationship, and the user presses the screen for more than a certain pressure and the user touches the screen for more than a certain duration to trigger the text zooming operation, preferably, the user presses the screen for more than a certain pressure for more than a certain duration to trigger the text zooming operation. Therefore, according to the above manner, when two contacts are detected, it is necessary to detect the pressure of the two contacts on the display interface and/or the duration of time for which the two contacts continuously contact the display interface. Whether the pressure of the contact is detected or the continuous contact duration is detected, the contact should continuously contact the display interface, and once the contact is stopped, the contact should be detected again.
S200: when the pressure and/or the duration of the contact exceeds a pressure threshold and/or a time threshold, acquiring the font size of the characters in the display interface as the initial font size
And after the pressure of the two contacts on the display interface and/or the duration of continuous contact of the two contacts on the display interface are detected, the zooming operation is triggered according to different trigger events. When the trigger event is that the user presses the screen to exceed a certain pressure, setting a pressure threshold, and when the pressure exceeds the pressure threshold, reading the font size of characters in the display interface as the initial font size, wherein the subsequent font size scaling is based on the initial font size; when the trigger event is that the touch screen of the user exceeds a certain duration, a time threshold is set, and when the duration exceeds the time threshold, the font size of characters in the display interface is read to serve as the initial font size. When the two conditions are in a logical OR relationship, when the pressure is detected to exceed the pressure threshold or the duration time exceeds the time threshold, the zooming operation can be triggered, and the font size of characters in the display interface is read as the initial font size; when the two conditions are in a logical AND relationship, when the pressure is detected to exceed the pressure threshold value and the touch screen duration time exceeds the time threshold value, the zooming operation can be triggered, and the font size of characters in the display interface is read to serve as the initial font size; when the trigger event is that the duration of the pressure exceeding a certain pressure value exceeds a certain threshold value, the scaling operation can be triggered, and the font size of the characters in the display interface is read as the initial font size.
S300: obtaining the coordinates of the initial position and the current position of the motion tracks of the two contacts on the display interface, and respectively calculating the zoom multiple of the first distance between the two contacts when the two contacts are located at the initial position and the second distance between the two contacts when the two contacts are located at the current position
After the scaling operation is triggered and the font size of the characters in the display interface is read as the initial font size, the scaling multiple needs to be calculated according to the change proportion of the distance between the touch points. Therefore, it is necessary to read coordinates of initial positions and current positions of the movement traces of the two touch points on the display interface, and it is clear that the movement traces of the touch points need to be continuous, that is, when the interruption of the touch point touch event is detected, the positions of the two touch points are final positions, zooming cannot be continued, and detection needs to be performed again until the trigger event is detected again. After the coordinates of the initial position and the current position of the motion track of the display interface of the two contacts are read, the distance between the two contacts at the initial position needs to be calculated as a first distance, the distance between the two contacts at the current position needs to be calculated as a second distance, and the second distance is divided by the first distance to obtain a zoom factor, wherein the zoom factor is not necessarily greater than 1, and can also be less than or equal to 1. The scaling factor is not a multiple of the final scaling of the font size, but a scaling factor of the font size needs to be calculated according to the scaling factor, for example, when the first distance is 2 and the second distance is 4, the scaling factor is 4/2 ═ 2, and the scaling factor of the font size does not necessarily equal 2, and needs to be adjusted according to the font size.
S400: calculating the target font size according to the initial font size and the zoom multiple, and adjusting the characters from the initial font size to the target font size
After the scaling factor is calculated, the target font size needs to be calculated by combining the initial font size, and firstly, the scaling factor needs to be calculated according to the scaling factor and the initial font size. The zoom factor is equal to the zoom multiple multiplied by a certain adjustment factor, the setting of the adjustment factor is related to the size of the zoom multiple, firstly, the zoom multiple needs to be divided into three conditions of being more than 1, being equal to 1 and being less than 1, when the zoom factor is equal to 1, the adjustment factor is 1, and the zoom factor is equal to 1; when the zoom factor is larger than 1, the adjusting coefficient should be larger than the reciprocal of the zoom factor, which may be a preset value, or may be set by the user, or may be obtained by the system through calculation, and when the preset or user-set adjusting coefficient is smaller than the reciprocal of the zoom factor, the adjusting coefficient is set to be a number slightly larger than the reciprocal of the zoom factor; when the zoom factor is smaller than 1, the adjustment coefficient should be smaller than the reciprocal of the zoom factor and larger than 0, which may be a preset value, or may be set by the user, or may be calculated by the system, and when the preset or user-set adjustment coefficient is smaller than the reciprocal of the zoom factor, the adjustment coefficient is set to a number slightly smaller than the reciprocal of the zoom factor. The scaling factor is the scaling multiple multiplied by the adjustment factor, after the scaling factor is obtained, the target font size is equal to the initial font size multiplied by the scaling factor, then the characters are reloaded, the characters are adjusted to the target font size from the initial font size, the adjustment of the font size of the characters can be updated from time to time, and the characters can also be directly adjusted to the final size when the touch screen event is finished.
After the configuration is adopted, the font size of the text can be recorded after a trigger event is detected by setting the trigger event, so that the font size of the text can be changed according to the change proportion of the distance between the touch points of the finger on the screen, and the text characters can be amplified and reduced.
Referring to fig. 2, in a preferred embodiment, the step of detecting the number of contacts simultaneously received by the display interface of the intelligent terminal, and when the number of contacts is two, detecting the pressure of the two contacts on the display interface and/or the duration of time for which the two contacts continuously contact the display interface includes:
s101: calling a touch screen event function in the intelligent terminal, and detecting the number of contacts simultaneously received by a display interface of the intelligent terminal
To finish the scaling of the size of the characters in the text, the display interface must have two contacts at the same time, and therefore, the number of the contacts received by the display interface of the intelligent terminal at the same time needs to be detected. And detecting the number of the contacts received by the display interface of the intelligent terminal at the same time, calling a touch screen event function in the intelligent terminal, reading position parameters of the contacts in the touch screen event function, wherein different positions represent different contacts, and the number of the positions is recorded as the number of the contacts.
S102: when the situation that the display interface receives two contacts at the same time is detected, a pressure sensor of the intelligent terminal is called, the pressure of the two contacts on the display interface is detected, and/or the duration time of the two contacts continuously contacting the display interface is recorded
The method comprises the steps of reading position parameters of contacts in a touch screen event function, when two different position parameter values exist at the same time, receiving the two contacts by a display interface at the same time, detecting different parameters according to set different trigger events, calling a pressure sensor of the intelligent terminal when the trigger events contain a pressure condition, detecting the pressure of the two contacts on the display interface, reading a pressure value, and recording the continuous contact duration time of the two contacts on the display interface when the trigger events contain a touch screen duration time condition.
Referring to fig. 3, in a preferred embodiment, the step of obtaining coordinates of an initial position and a current position of the motion trajectory of the two touch points on the display interface, and respectively calculating a zoom multiple of a first distance between the two touch points when the two touch points are located at the initial position and a second distance between the two touch points when the two touch points are located at the current position includes:
s301: obtaining the coordinates of the initial positions of the two contact points, calculating the distance between the initial positions of the two contact points, and recording as a first distance
When the zoom factor is calculated, firstly, the coordinates of the initial positions of the two touch points are acquired, and the distance between the two coordinates is calculated according to the coordinate values, namely the distance between the initial positions of the two touch points, and the distance is recorded as a first distance.
S302: obtaining the coordinates of the current positions of the two contacts, calculating the distance between the current positions of the two contacts, and recording as a second distance
After the distance between the initial positions of the two contacts is obtained, the distance between the current positions of the two contacts needs to be obtained in real time, so that the scaling multiple is calculated according to the proportion between the two distances. Obtaining the distance between the current positions of the two touch points also requires obtaining coordinates of the current positions of the two touch points, calculating the distance between the two coordinates, and recording the distance as a second distance.
S303: dividing the second distance by the first distance to calculate a zoom factor
After the first distance and the second distance are obtained, the scaling factor is equal to the second distance divided by the first distance, and thus the scaling factor is calculated.
Referring to fig. 4, in a preferred embodiment, the step of calculating a target font size according to the initial font size and the scaling factor and adjusting the text from the initial font size to the target font size specifically includes:
s401: calculating font scaling factor according to the scaling factor
After the zoom factor is obtained, the system can calculate an adjustment coefficient according to the zoom factor and the initial font size through a set algorithm, and the zoom factor is multiplied by the adjustment coefficient to calculate the zoom factor. When the scaling multiple is greater than 1, the scaling multiple is Ks, the adjustment coefficient is Kt, the scaling coefficient is K, the initial font size is X1, a font library in the intelligent terminal is read, the maximum font size is Xmax, the first distance is L1, the second distance is L2, the diagonal length of the measurement display interface is Lmax, the ratio of the diagonal length of the measurement display interface to the first distance is calculated to be K1-Lmax/L1, meanwhile, the scaling multiple is L2/L1, the ratio of the maximum font size to the initial font size is K2-Xmax/X1, the adjustment coefficient Kt K2/K1, the scaling coefficient K-Ks-Kt-Ks (L2/L1) (K2/K1) -Ks 2)/(X1-lmmax), and meanwhile, that is, when Kt > 1/L > 8656, i.e., K8642 is slightly greater than K8642 + K8642, and K8642 is K8642 + K8642, can be set in advance, prevent the zoom multiple Ks > 1 and the zoom factor K < 1; when the scaling factor is equal to 1, the adjusting coefficient is 1, the scaling factor is equal to the scaling factor multiplied by the adjusting coefficient, and the scaling factor is 1; when the scaling multiple is less than 1, the scaling multiple is also denoted as Ks, the adjustment coefficient is Kt, the scaling coefficient is K, the initial font size is denoted as X1, a font library in the intelligent terminal is read, the minimum font size is Xmin, the first distance is L1, the second distance is L2, the minimum distance between two touch points is set as Lmin, the minimum distance is the limit minimum distance of a touch point which can be touched by a human finger on a display interface, the ratio of the minimum distance between the two touch points to the first distance is calculated as K1 Lmin/L1, meanwhile, the scaling multiple is L2/L1, the ratio of the minimum font size to the initial font size is K2 > -Xmin/X1, the adjustment coefficient Kt ═ K2/K1, the scaling coefficient K ═ Kt ═ 1 (L638) (K1)/(xxmin/K1), namely, K ═ 27 ═ K ═ 2 ≦ K ≦ 2, and when K ≦ K1 is equal to K ≦, let Kt be L1/L2-K3, K3 be a value slightly larger than 0, and K3 < L1/L2, which can be set in advance to prevent the scaling factor Ks < 1 and the scaling factor K > 1.
To make the scaling smoother, preferably, when the scaling multiple is not equal to 1, let Lmax/Lmin, K2 be Xmax/Xmin, the adjustment coefficient be Kt be K2/K1, and the scaling coefficient be Ks Kt.
S402: multiplying the initial font size by the font scaling factor to calculate a target font size
After the scaling factor is calculated, the target font size is the original font size multiplied by the font scaling factor. Marking the target font size as X, and when the zoom multiple is larger than 1, marking the target font size as X-1-K-X1-Ks-Kt; when the scaling multiple is equal to 1, the scaling coefficient is equal to 1, and the target font size is equal to the current font size; when the zoom factor is smaller than 1, the target font size is X-X1-K-X1-Ks-Kt.
S403: adjusting the current font from the initial font size to the target font size
After the target font size is obtained, the current character needs to be adjusted from the initial font size to the target font size, and the text content is reloaded, wherein the character font size of the text content is the target font size.
Fig. 5 is a schematic flow chart of a font size control method based on an intelligent terminal according to another preferred embodiment of the present invention. In this embodiment, between the step of multiplying the initial font size by the font scaling factor to calculate the target font size and the step of adjusting the current font from the initial font size to the target font size, the font size control method further includes the following steps:

S405: when the target font size exceeds the maximum font size, controlling the target font size to be the maximum font size, and when the target font size is lower than the minimum font size, controlling the target font size to be the minimum font size
When the calculated target font size exceeds the preset maximum font size, the target font size is changed to be the maximum font size, and when the calculated target font size is lower than the preset minimum font size, the target font size is changed to be the minimum font size.
Referring to fig. 6, a font size control system based on an intelligent terminal according to a preferred embodiment of the present invention specifically includes the following components:
the detection module needs to set a trigger event to realize the zooming of the text content, so as to prevent the reduction of user experience caused by the misoperation of the user. The method comprises the steps of firstly detecting the number of touch points simultaneously received by a display interface of the intelligent terminal, wherein the number of touch points is the number of positions where touch screen events occur at different positions of the display interface by a user, and when the situation that the display interface simultaneously receives 2 touch points is detected, the user is considered to possibly zoom in and out a text. The trigger event may be that the user presses the screen for more than a certain pressure, or the user touches the screen for more than a certain duration, or the two conditions are in a logical or relationship, where the user presses the screen for more than a certain pressure or the user touches the screen for more than a certain duration to trigger the text zooming operation, either one of the two conditions may be selected, or the two conditions are in a logical and relationship, and the user presses the screen for more than a certain pressure and the user touches the screen for more than a certain duration to trigger the text zooming operation, preferably, the user presses the screen for more than a certain pressure for more than a certain duration to trigger the text zooming operation. Therefore, according to the above manner, when two contacts are detected, it is necessary to detect the pressure of the two contacts on the display interface and/or the duration of time for which the two contacts continuously contact the display interface. Whether the pressure of the contact is detected or the continuous contact duration is detected, the contact should continuously contact the display interface, and once the contact is stopped, the contact should be detected again.
And the initial font size acquisition module is connected with the detection module, and triggers zooming operation according to different trigger events after detecting the pressure of the two contacts on the display interface and/or the duration of continuous contact of the two contacts with the display interface. When the trigger event is that the user presses the screen to exceed a certain pressure, setting a pressure threshold, and when the pressure exceeds the pressure threshold, reading the font size of characters in the display interface as the initial font size, wherein the subsequent font size scaling is based on the initial font size; when the trigger event is that the touch screen of the user exceeds a certain duration, a time threshold is set, and when the duration exceeds the time threshold, the font size of characters in the display interface is read to serve as the initial font size. When the two conditions are in a logical OR relationship, when the pressure is detected to exceed the pressure threshold or the duration time exceeds the time threshold, the zooming operation can be triggered, and the font size of characters in the display interface is read as the initial font size; when the two conditions are in a logical AND relationship, when the pressure is detected to exceed the pressure threshold value and the touch screen duration time exceeds the time threshold value, the zooming operation can be triggered, and the font size of characters in the display interface is read to serve as the initial font size; when the trigger event is that the duration of the pressure exceeding a certain pressure value exceeds a certain threshold value, the scaling operation can be triggered, and the font size of the characters in the display interface is read as the initial font size.
And the zooming multiple acquisition module is connected with the initial font size acquisition module, triggers zooming operation, reads the font size of characters in the display interface as the initial font size, and then calculates the zooming multiple according to the change proportion of the distance between the contact points.

The scaling factor is the scaling multiple multiplied by the adjustment factor, after the scaling factor is obtained, the target font size is equal to the initial font size multiplied by the scaling factor, then the characters are reloaded, the characters are adjusted to the target font size from the initial font size, the adjustment of the font size of the characters can be updated from time to time, and the characters can also be directly adjusted to the final size when the touch screen event is finished.
