Description

Personalized screen character spacing adjustment method and device based on visual crowding effect

technical field

The invention relates to the field of computer technology, in particular to a method and a device for adjusting the spacing between characters on a personalized screen based on the visual crowding effect.

Background technique

In daily life, almost all visual objects are surrounded by distracting objects rather than existing alone, especially when recognizing words. Chinese text is composed of Chinese characters closely arranged. Due to the high complexity of Chinese characters, the composition of the text is relatively dense. Chinese reading needs to rely on more visual cognitive resources. This means that visual factors play a greater role in Chinese character recognition. Due to the existence of visual crowding effect, people will be affected to varying degrees when using electronic products for normal reading activities, thereby reducing the accuracy and efficiency of reading. This phenomenon is especially obvious in special groups of people (such as dyslexia, amblyopia, etc.) . Existing studies have found that properly adjusting the word spacing of a text can reduce the crowding effect, thereby effectively improving the reading efficiency of normal readers and even those with dyslexia. Currently, the more common character spacing adjustment methods on the market are completely dependent on the user's experience selection, which is relatively random, and cannot accurately formulate the optimal setting according to the user's individuality.

Detailed ways

It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

The visual crowding effect refers to the phenomenon that when an object is surrounded by other objects, the recognition of the object will be affected by the surrounding objects. Taking Figure 1 as an example, "+" is the gaze point. When observing the letter R on the right, it can be clearly recognized because there is no interference around it; when observing the letter R (specified target character) on the left, there are two Interfering objects S and Z affect the recognition of the letter R, and even make the letter R unrecognizable. The distance between the gaze point "+" and the designated target character "R" is called the eccentricity, and the interference stimulus "S" can affect The maximum distance to the subject's recognition of the designated target character "R" is called the critical distance.

Due to the existence of the visual crowding effect, people will be affected to varying degrees when using electronic products for normal reading activities, thereby reducing the accuracy and efficiency of reading.

As shown in Figure 2, Figure 2 is a specific embodiment of a method for adjusting the distance between characters on a personalized screen based on the visual crowding effect in the present invention, including:

S1, presenting a first picture, the first picture including: a preset gaze point and a target character, the target character being located on the same horizontal line as the gaze point;

As shown in Figure 4, 1 is the gaze point, and the target character is "木月天".

S2, receiving the identification data of the specified target character;

S1-S2 are target character recognition tests set based on the visual crowding effect.

During the test, the user always looks at the fixation point and recognizes the target character specified in the target characters with peripheral vision. The target character specified in this embodiment is the middle target character "month", and the target character recognized by the user is received.

Multiple groups of target characters are selected from the font library, the target characters are randomly selected from the material library, and the designated target character recognition test of steps S1-S2 is performed.

Because the structures of Chinese characters, letters, and numbers are very different, and the appropriate word spacing is different, in this implementation, the target characters are divided into three categories of Chinese characters, letters, and numbers for testing.

Considering the different levels of users' mastery of Chinese characters, select 300 relatively common simple Chinese characters with a word frequency of 20-100/million and strokes of 4-10 strokes to enter the material library. In order to eliminate the influence of different pronunciations, polyphonic characters are excluded. .

In this embodiment, 26 lowercase English letters and ten Arabic numerals from 0 to 9 are selected.

In order to prevent the user from forming a stereotype and subconsciously gazing at one side, the target characters randomly appear on the left or right side of the preset gazing point.

For the recognition of Chinese characters, voice recognition is used to guide the user to read the Chinese characters and judge whether the user recognizes the Chinese characters correctly.

For the recognition of letters and numbers, guide the user to input the recognized letters or numbers through the keyboard.

Many previous studies have confirmed that the crowding effect has nothing to do with the size of the font. Therefore, for the convenience of testing, 24 boldface characters are selected as the Chinese font in the material library. The distance between the user's eyes and the screen is set according to the user's reading habits.

S3, statistically identifying the correct rate of the designated target character;

S4, adjusting the character spacing of the target character;

Adjust the word spacing between the target characters in turn, such as adjusting to 1°, 1.5°, 2°, 2.5°, 3°, 3.5°, 4°, 4.5°, 5°, 5.5° angle of view (the angle of view is the center of the specified target character point and the center point of the disturbance), and re-execute steps S1-S3.

S5. When the accuracy rate of the target character reaches a preset value, store the value of the word spacing of the target character at this time.

The word spacing at this time is the word spacing that is suitable for the user's reading habits and helps to improve reading efficiency.

In another embodiment, before step S1, it also includes the step of: presenting the zeroth picture, the zeroth picture includes a preset gaze point, the zeroth picture is shown in Figure 3, and the user guides the user to concentrate on the next step test.

In another embodiment, after step S1, an execution step is also included: presenting a second screen, the second screen is used to guide the user to input the recognition data of the specified target character, the schematic diagram of the second screen is shown in Figure 5 .

In another embodiment, before step S1, a step of acquiring basic information of the user is further included, and the basic information includes: name, gender and age. By obtaining the basic information of the user and combining the word spacing indicated by the user, it is convenient to statistically analyze the character spacing characteristics of the same type of users, and automatically adjust the word spacing according to the account information output by the user to match the user's reading habits.

As shown in Figure 6, Figure 6 is a schematic structural diagram of a specific embodiment of a device for adjusting the distance between characters on a personalized screen based on the visual crowding effect, including:

A display module, configured to present a first picture, the first picture includes: a preset gaze point and a target character, and the target character is located on the same horizontal line as the gaze point;

The recognition data receiving module is used to receive the recognition data of the specified target character;

Statistical module, used for statistically identifying the correct rate of designated target characters;

Word spacing adjustment module, used to adjust the word spacing of the target character;

Further, the display module is also used to present the zeroth picture and/or the second picture,

The zeroth frame includes a preset gaze point;

The second screen is used to guide the user to input the recognition data of the specified target character.

Further, it also includes a user information acquisition module to acquire the basic information of the user, and the basic information includes: name, gender and age.

Further, the recognition data receiving module includes a speech recognition device and/or a keyboard.
