Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. 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 method for adjusting screen fonts of the embodiment of the invention can be executed in any suitable type of user terminal with a user interaction device and a processor with computing capability, such as a desktop computer, a smart phone, a tablet computer and other user terminals.
The screen font adjusting device of the embodiment of the invention can be used as one of software or hardware functional units and independently arranged in the user terminal, and also can be used as one of functional modules integrated in a processor to execute the screen font adjusting method of the embodiment of the invention.
Fig. 1 is a flowchart of a method for adjusting a font of a screen according to an embodiment of the present invention. As shown in fig. 1, the method includes:
0102, acquiring the current distance between human eyes and a terminal screen and the vision type;
when a user uses the terminal to browse the information content through the screen, the terminal presents characters corresponding to the information content in a display area of the screen, and the characters comprise fonts and meanings represented by the fonts. For convenience of description in conjunction with the embodiments, the text herein may be understood as a font, that is: the text of the screen presentation may be understood as the font of the screen presentation.
It should be understood by those skilled in the art that the terminal screen may be a touch screen or a non-touch screen, and may be a TFT screen (TFT Thin Film Transistor), a TFD screen (TFD Thin Film Diode), a UFB screen (Ultra Fine Bright, UFB), an STN Screen (STN), an OLED screen (Organic Light-Emitting Diode), an AMOLED screen (Active Matrix/Organic Light-Emitting Diode, AMOLED Active Matrix Organic Light-Emitting Diode panel), and so on.
Of course, in order to facilitate the user to browse the screen fonts more clearly, those skilled in the art may also select a terminal screen with a large size, a high contrast, a high definition, or other performance, which is not limited to the terminal screen shown in this embodiment.
In this embodiment, the terminal has a built-in distance detector. When a user holds the terminal to look at, the distance detector can collect the distance between eyes of the user and the terminal screen, and further the terminal calculates the current distance between the eyes and the terminal screen according to a preset distance model. The current distance here may be a distance between the human eye and the screen center point, or may be other parameters transformed according to a mathematical formula and used to evaluate the current distance between the human eye and the terminal screen. And polling the access distance detector by the terminal according to a certain frequency so as to obtain the current distance between the human eyes and the terminal screen at different time points. In some embodiments, the distance detector includes, but is not limited to, the following devices: infrared detectors, laser detectors, and echo detectors.
The vision types include a myopic eye type, a hyperopic eye type, and a normal eye type. The vision type of the user can be obtained by the terminal according to a preset rule, or can be obtained by the terminal according to the selection of the user on a terminal screen, and the method is not limited to the mode of obtaining the vision type.
0104, adjusting the font of the terminal screen according to the eyesight type and the current distance.
And the terminal adjusts the font of the terminal screen according to the eyesight type and the current distance. For example, when the user is of a near-sighted type, the terminal continuously adjusts the font size of the terminal screen following a change in the current distance, and optionally, the longer the distance, the larger the terminal adjusts the font size of the terminal screen. When the user is of a far-sighted type, the terminal continuously adjusts the font size of the terminal screen along with the change of the current distance, optionally, the longer the distance is, the larger the terminal adjusts the font size of the terminal screen, but when the current distances of the near-sighted user A and the far-sighted user B are the same, the method for differentially presenting the font sizes of the terminal screen is adopted, and the method can meet the visual demands of consumers with different vision types by considering the visual perception and the browsing demands of the near-sighted user A and the far-sighted user B, wherein the font size browsed by the near-sighted user A is larger than the font size browsed by the far-sighted user B, namely the font size presented by the terminal screen of the near-sighted user A is larger than that. Those skilled in the art should note that: the font adjustment strategy of the terminal screen is only described by way of example, and a designer can define various adjustment strategies according to job requirements, but the invention is not limited to this.
In this embodiment, the font includes font size, shape, color, type, and rendering position. Therefore, in addition to the above manner in which the terminal adjusts the font size, the terminal can also adjust the font shape, color, type, and rendering position to meet the needs of diversified users.
In the embodiment of the invention, by adopting the method, consumer groups with different vision types can be adapted, so that the requirements of diversified users are met.
In some embodiments, as shown in fig. 2, before performing step 0102, the method may further include:
0106, obtaining the use distance between eyes and a terminal screen when a user normally uses the terminal;
0108, determining the vision type according to the relationship between the use distance and the normal vision distance.
For a myopia user, the terminal collects the distance between the human eyes and the terminal screen at different time points when the terminal is used by the user in history through the distance detector, all collected data are counted, and the counted data are analyzed, so that the using distance between the human eyes and the terminal screen when the user uses the terminal normally is obtained. For example, when the user is of the myopic eye type, the data set collected by the terminal through the distance detector is (12, 10,11,10,15,13,11,12,8,9), and the distance of the embodiment is in centimeters and cm. The terminal counts the 10 groups of data and calculates an average value of 11.1cm, the terminal takes the calculated average value of 11.1cm as the use distance between human eyes and a terminal screen when a user normally uses the terminal, the use distance 11.1 is stored, and the use distance 11.1 is obtained before the terminal obtains the current distance between the human eyes and the terminal screen. Similarly, when the user is of the presbyopic type, the data set collected by the terminal through the distance detector is (25, 23,22,22,24,26,19,18,20,20), and the average value is found to be 21.9 cm. Those skilled in the art will note that: the use distance of the near-sighted type or the far-sighted type for different users varies from person to person, which is shown in the present embodiment by way of example only and is not meant to limit the "use distance" taught by the present embodiment, and the "use distance" may be a distance range in some embodiments, rather than a specific distance value.
The normal vision distance is the normal distance between the human eyes and the terminal screen when the user is in a normal eye type and can clearly browse the font of the terminal screen. The normal vision distance may be a specific distance value, or may be a range value. For example, the normal vision distance of the present embodiment is 15cm, or 15cm to 18 cm.
When the normal vision distance is a specific distance value, the terminal judges whether the use distance is larger than the normal vision distance after acquiring the use distance, if the use distance is larger than the normal vision distance value, the terminal determines that the user is in a presbyopia type, if the use distance is smaller than the normal vision distance value, the terminal determines that the user is in a myopic type, and if the use distance is equal to the normal vision distance value, the terminal determines that the user is in a normal eye type.
When the normal vision distance is a distance range value, the terminal judges whether the use distance is larger than the minimum value of the normal vision distance after acquiring the use distance, if the use distance is larger than the maximum value of the normal vision distance, the terminal determines that the user is of a presbyopia type, if the use distance is smaller than the minimum value of the normal vision distance, the terminal determines that the user is of a myopic type, and if the use distance falls into the normal vision distance, the terminal determines that the user is of a normal eye type.
In the embodiment, the terminal can automatically analyze the eyesight of the user, so that the method can be effectively adapted to various types of users.
In some embodiments, the terminal may adjust the objects on the terminal screen by looking up a table. Optionally, step 0104 comprises:
and adjusting the font size corresponding to the current distance presented by the terminal screen according to the first adjustment relation among the eyesight type, the current distance and the preset font size.
The designer constructs a font lookup table at the terminal in advance according to the operation purpose, and the terminal traverses the lookup table according to the eyesight type and the current distance to find out the font size corresponding to the current distance. Table 1 is a font size lookup table in a myopia type state according to an embodiment of the present invention.
TABLE 1
As shown in table 1, when the terminal determines that the user is a type of myopia, the terminal traverses the lookup table according to the current distance to find the font size corresponding to the current distance. For example, when the current distance is 6cm, the terminal finds: in the first row, the current distance of 6cm falls within the preset distance range of 5-7cm, and thus, when the current distance is 6cm, the terminal adjusts the screen font size to 5 mm. When the current distance is 10cm, the font size is adjusted to 6 mm. From table 1, it can be derived: when the current distance is less than 30cm, the current distance is in direct proportion to the size of the font, the shorter the current distance is, the smaller the font is, and the longer the current distance is, the longer the font is. From table 1 it can also be found that: when the current distance is greater than 16cm, the font size adjustment steps are from "1" to "2". In fact, when the preset distance range is 14-16cm, it represents the normal distance under the normal eye type. For a user with myopia, in order to adapt to the visual perception and definition of the user with myopia, the font size needs to be quickly adjusted to be larger when the distance is larger than the normal distance, and the font size can be slowly adjusted to be smaller when the distance is smaller than the normal distance. From table 1 it can also be found that: when the current distance is more than 30cm, the adjustment of the font size is fixed, and for a myopic eye type user, the adjustment manner of enlarging the font size over a long distance to enable the user to clearly see the font is meaningless, even in an enlarged state, when the font seen by the myopic eye user is blurred, and when the size of the font is considered in consideration of the size of the screen and the display content, the font size does not need to be enlarged again.
Table 2 is a table for looking up the font size in the presbyopia type state according to an embodiment of the present invention.
TABLE 2
As shown in table 2, it can be derived: when the current distance is less than 30cm, the current distance is in direct proportion to the size of the font, the shorter the current distance is, the smaller the font is, and the longer the current distance is, the longer the font is. From table 1 it can also be found that: when the current distance is greater than 16cm, the font size adjustment steps from "2" to "1". In fact, when the preset distance range is 14-16cm, it represents the normal distance under the normal eye type. For a presbyopic type user, in order to be suitable for the visual perception and the definition of the presbyopic user, the font size can be gently increased when the distance is larger than the normal distance, and the font size can be rapidly decreased when the distance is smaller than the normal distance. From table 1 it can also be found that: when the current distance is more than 30cm, the adjustment of the font size is fixed, and for the presbyopia type user, the adjustment manner of enlarging the font size over a long distance to enable the user to clearly see the font is meaningless, and the font size does not need to be enlarged again at this time in consideration of the size of the screen and the display contents.
It will be appreciated by those skilled in the art that the strategy for adjusting the font size for the near-sighted type or the far-sighted type shown herein is merely exemplary, and the designer may also flexibly change the adjustment strategy depending on the task. However, any replacement, as long as the table lookup is used to adjust the font size, should fall within the scope of the present invention.
In some embodiments, the terminal may adjust the objects of the terminal screen through a mathematical model. Optionally, step 0104 comprises:
and adjusting the font size corresponding to the current distance presented by the terminal screen according to the second adjustment relation between the eyesight type and the current distance.
In this embodiment, optionally, the second adjustment relationship is: the font size of the current distance { (current distance-first correction parameter)/reference distance }. the reference font size, the first correction parameter is determined according to the eyesight type, and the reference distance and the reference font size are preset.
When the user is of the myopic eye type, the first correction parameter is C1; when the user is of the presbyopic type, the first correction parameter is C2, where C1 is smaller than C2. When the user is of a normal eye type, the first correction parameter is C3, and C3 is larger than C1 and smaller than C2. When the current distances of the near-sighted user and the far-sighted user are the same, for example, for the near-sighted user, the current distance D1 is 10cm, the first correction parameter C1 is 2cm, the reference distance is 15cm, and the reference font size is 4mm, and thus, the font size Z1 of the current distance is 2.13 mm. However, for a far-sighted user, the current distance D1 is 10cm, the first correction parameter C2 is 4cm, the reference distance is 15cm, and the reference font size is 4mm, and therefore, the font size Z2 for the current distance is 1.6 mm. Similarly, for a normal eye type user, the first correction parameter is C3 is 3, and the font size Z3 for the current distance is 1.9 mm.
For another example, for a myopic user, the current distance D1 is 20cm, the first correction parameter C1 is 2cm, the reference distance is 15cm, and the reference font size is 4mm, so the font size Z1 for the current distance is 4.8 mm. However, for a far-sighted user, the current distance D1 is 20cm, the first correction parameter C2 is 4cm, the reference distance is 15cm, and the reference font size is 4mm, and therefore, the font size Z2 for the current distance is 4.27 mm. Similarly, for a normal eye type user, the first correction parameter is C3 is 3, and the font size Z3 for the current distance is 4.5 mm. The present embodiment adjusts the font size of the terminal screen of the myopic-type user to be larger than that of the hyperopic-type user at the same current distance in consideration of the visual perception and font definition of the myopic user and the hyperopic user.
In this embodiment, the value range of the first correction parameter is 0 to 5, and of course, the designer sets the value range of the first correction parameter by himself or herself according to the purpose of the work. However, the first correction parameter should not be too large in consideration of users with different eyesight types and font definition.
In some embodiments, optionally, the second adjustment relationship is:
the font size of the current distance is ± { (current distance/reference distance) × (second correction parameter }), the reference font size is preset, and the second correction parameter is determined according to the eyesight type.
Optionally, when the second correction parameter is a positive number, the font size of the current distance is equal to the reference font size + { (current distance/reference distance) × the second correction parameter }.
Optionally, when the second correction parameter is a negative number, the font size of the current distance is equal to the reference font size- { (current distance/reference distance) × the second correction parameter }.
When the user is of the myopic eye type, the second correction parameter is a positive number C4; when the user is of the presbyopic type, the second correction parameter is a positive number C5, wherein C5 is smaller than C4. When the user is of a normal eye type, the second correction parameter is a positive number C6, and C6 is greater than C5 and less than C4. When the current distances of the near-sighted user and the far-sighted user are the same, for example, for the near-sighted user, the reference font size is 1mm, the current distance is 10cm, the reference distance is 15cm, the second correction parameter C4 is 2, and the font size Z4 of the current distance is 2.3 mm. Similarly, for a hyperopic user, the second correction parameter C5 is 4 and the font size Z5 for the current distance is 3.7. Similarly, for a normal vision type user, the second correction parameter C6 is 3, and the font size Z6 for the current distance is 3 mm. The present embodiment adjusts the font size of the terminal screen of the myopic-type user to be larger than that of the hyperopic-type user at the same current distance in consideration of the visual perception and font definition of the myopic user and the hyperopic user.
In this embodiment, the value range of the second correction parameter is 0 to 5, and of course, the designer sets the value range of the second correction parameter by himself or herself according to the purpose of the work. However, the second correction parameter should not be too large in consideration of users with different eyesight types and font definition.
In some embodiments, as shown in FIG. 3, when the user's vision type is to be determined, the terminal screen 31 presents three vision modes for the user to select, including a near vision mode 311, a far vision mode 312, and a normal mode 313. Specifically, as shown in fig. 3a, before step 0102, the method includes:
step 0110, receiving a selection event input by a user;
and step 0112, determining the selected vision type according to the selection event.
After the terminal presents three vision modes on the screen, a user selects a corresponding vision mode on the screen according to own vision attributes, and the terminal distributes and receives selection events according to selection operations of the user on the screen. And the terminal determines the vision type selected by the user according to the selection event. In some embodiments, when the terminal receives the selection event, the terminal hides the near vision mode 311, the far vision mode 312, and the normal mode 313.
It should be understood by those skilled in the art that when a user performs a touch operation on the terminal screen, the terminal should have a touch-sensitive surface, which may be a touch screen display, and may be a touch pad. The touch-sensitive surface serves as an input interface for user operations, and operations of a user on the touch-sensitive surface can be detected, wherein the operations can be single-clicking, double-clicking, sliding, long-pressing, dragging and the like on the touch-sensitive surface. Each operation by the user generates a certain pressure intensity on the touch-sensitive surface, which can be detected using various methods and various sensors or combinations of various sensors. For example, by detecting the magnitude of the change in capacitance of the touch-sensitive surface at the touch-sensitive surface, or by detecting the magnitude of the change in resistance of the touch-sensitive surface, or by detecting the magnitude of the change in capacitance and the magnitude of the change in resistance of the touch-sensitive surface, and so on. In the above process, the intensity of the pressure generated by the touch-sensitive surface is converted into an electrical signal by the sensor, the terminal issues a selection event according to the electrical signal according to the control command generated by the user on the touch-sensitive surface, and receives and processes the selection event.
