FIG. 1 schematically illustrates a flowchart of a method for magnifying a test question based on an eye movement locus according to an embodiment of the present application.

As shown in FIG. 1, the method for magnifying a test question based on an eye movement trajectory may include steps S101 to S106, where:

In step S101, it is monitored that the electronic test questionnaire is opened, and the current resolution of the display screen on which the electronic test questionnaire is displayed is acquired.

The test question magnification scheme based on eye movement trajectories provided in the embodiments of the present application may be applied to electronic devices, and the electronic devices may include, but are not limited to, mobile phones, tablet computers, notebook computers, and desktop computers. According to the embodiment of the present application, when the electronic device detects that the agent opens the electronic test questionnaire or detects that the electronic test questionnaire has been opened, the current resolution of the display screen for displaying the electronic test questionnaire can be automatically obtained. Obtaining the current resolution of the display screen used to display the electronic test questionnaire may be obtaining the screen attributes of the display screen on which the electronic test questionnaire is located, where the screen attributes include the current resolution. Specifically, the screen attribute can be obtained by a Javascript function. The display screen may be carried by the electronic device itself, or may be external to the electronic device, which is not limited herein.

It should be noted that the electronic test questionnaire can be a specific electronic page in the website. For example, if the website is a loan type website, the electronic test questionnaire may be an electronic test questionnaire displayed at one end of an agent in a video interview service.

Step S102: Obtain a preset basic resolution.

In the embodiment of the present application, the preset base resolution may be set by the agent himself. That is, the preset basic resolution can be adjusted, and for different display screens, it can correspond to different values.

Step S103: Calculate the current magnification according to the current resolution and the preset basic resolution.

In the embodiment of the present application, after the electronic device obtains the current resolution and the preset basic resolution, the current resolution can be divided by the preset basic resolution to obtain the current magnification. It should be noted that, in order to ensure that the magnification is at least equal to or greater than 1, the preset basic resolution may be less than or equal to the current resolution. Preferably, the preset basic resolution may be smaller than the current resolution.

For example, if the current resolution is 1920 × 1080 and the preset base resolution is 1280 × 1024, the current magnification can be (1920 × 1080) ÷ (1280 × 1024) ≈1.58.

Step S104: Determine the eye movement track of the agent.

In the embodiment of the present application, since the agent's eyeballs are moving during the process of browsing the test questions, the agent's eyeball trajectory needs to be determined before determining which test question the agent is viewing.

Determining the eye movement trajectory of the agent may include: obtaining multiple images of the agent based on the electronic test questionnaire collected by the camera within a preset time period; determining the relative position of the agent's eyeball in each of the multiple images, and obtaining multiple Relative positions; and determining eye movement trajectories based on the plurality of relative positions.

According to the embodiment of the present application, the camera may be a front-facing camera for capturing an image of an agent located in front of the display screen. Specifically, the camera can continuously capture multiple images of the agent within a preset period of time, where the multiple images may include images of the agent browsing the electronic test questionnaire, especially when viewing the test question, preferably, the size of each image is similar to The display size of the display area of the display screen is the same. Further, determine the relative position of the eyeball of the agent in each image, for example, take the center of the image as the origin, the vertical axis direction directly, and the horizontal axis direction to the right, establish a coordinate system, and then determine the eyeball of the agent in each image. The coordinates in an image, so that the eye movement of the seat can be determined.

For example, the camera took 4 images, taking the left eyeball of the agent as an example, where the coordinates of the left eyeball in the first image are (3,3.9) and the coordinates of the second image are (5,4.2), In the third image, the Chinese coordinates are (8,4.4), and in the fourth image, the coordinates are (9,3.8). Based on these coordinates, the eye movement trajectory of the seat can be determined.

Step S105: Determine a test question corresponding to the eye movement trajectory in the electronic test questionnaire.

Wherein, determining the test question corresponding to the eye movement trajectory in the electronic test questionnaire may include: determining a mapping region corresponding to the eye movement trajectory; and determining the test question corresponding to the mapping region in the electronic test questionnaire.

According to the embodiment of the present application, since the eye movement trajectory is determined according to the coordinates, a corresponding mapping area can also be determined according to these coordinates. For example, in combination with the above example, if the size of the image is the same as the display size of the display area of the display screen, the coordinates of the four top corners of the mapping area are the four coordinates of the eye movement trajectory, namely, (3,3.9), ( 5,4.2), (8,4.4), and (9,3.8); if the image size is different from the display size of the display area of the display screen, the ratio of the image size to the display size can be determined. Based on the ratio and the above eyeballs The four coordinates of the motion trajectory determine the mapping area. If the ratio is 1: 2, the coordinates of the four top corners of the mapping area are: (6,7.8), (10,8.4), (16,8.8), and ( 18,7.6).

Further, test questions corresponding to the mapped area can be found from the electronic test questionnaire. Among them, if a certain test question falls within the mapping area, the test question must be a test question corresponding to the mapping area; if a part of a test question falls within the mapping area, the test question can also be Test questions corresponding to the mapped area.

In step S106, the test question is enlarged according to the current magnification.

The enlargement of the test question includes: determining the current font size of the test question; and enlarging the test question according to the current magnification and the current font size.

Specifically, since the test subject is not enlarged, the corresponding font size is the current font size. In order to accurately determine the size of the test question, the current font size can be determined first, and the current magnification and the current font size are multiplied, and then the font size of the font to be enlarged can be obtained.

For example, in combination with the above example, if the current font size is 18px, the enlarged font size can be 1.58 × 18px = 28.44px.

It should be noted that if the calculated font size of the test question is a decimal, the rounding process can be performed, such as rounding down, rounding up, and so on. Preferably, if the value after the decimal point is less than 5, it can be rounded down, for example, 28.44 after rounding down is 28; if the value after the decimal point is 5 or greater, it can be rounded up, such as 28.5 up. Rounded to 29.
