With reference to the foregoing embodiments, a scenario of a password input interface of a password APP is taken as an example to illustrate a workflow of software and hardware in which a terminal highlights a number 3.

In one possible embodiment, as shown in fig. 15, the process of the terminal determining that the user highlights the number 3 when selecting the number 3 based on the eye tracking function (taking the highlighted playback mechanism of fig. 6 as an example) may include the following steps:

s11, the infrared emitter 495 emits infrared light that illuminates a face of a user to form a spot in the human eye.

In particular, infrared actuation of the inner core layer may enable infrared emitter 495 to emit infrared light.

S12, the camera 493 collects an eye image of the pupil including the light spot, and sends the eye image to the eye tracking application of the application layer.

Specifically, the camera drive of the inner core layer can enable the front camera of the terminal, and human eye images are collected through the front camera.

It will be appreciated that the eye tracking application may be a factory preset system level application.

S13, the eye tracking application processes the eye image, calculates the gaze direction and gaze point of the user, and sends the gaze point to the password APP.

And S14, the password APP determines that the object is the number 3 according to the fixation point, generates a highlight instruction aiming at the number 3, and sends the highlight instruction to the view system of the application framework layer.

S15, the view system of the application framework layer calls the display driver of the kernel layer, and the number 3 is highlighted on the password input interface of the password APP through the display screen 494.

In a possible embodiment, as shown in fig. 16, the above-mentioned interactive confirmation mechanism of the terminal through the volume + key (taking the interactive confirmation mechanism of fig. 12 as an example) may include the following steps:

s21, the user presses the volume + key 2 times in succession to generate 2 hardware interrupt signals, and the 2 hardware interrupt signals are sent to the kernel layer.

Specifically, the hardware interrupt signal may be an electrical signal.

And S22, the kernel layer processes the 2 hardware interrupt signals into original input events and sends the original input events to the application framework layer.

And S23, the application framework layer identifies the physical key corresponding to the original input event as a volume + key, generates an interactive confirmation event by combining the event interval and sends the interactive confirmation event to the password APP.

And S24, the password APP generates an instruction that the confirmation result is accurate according to the interactive confirmation event, and the adjustment process of the eyeball tracking virtual screen is triggered.

Referring to fig. 18, fig. 18 is a flowchart illustrating an interface display method according to an embodiment of the present application.

S1801, displaying a target interface on a screen, where an eyeball tracking virtual screen of the target interface is associated with one or more objects that can be selected through an eyeball tracking function, where the eyeball tracking virtual screen refers to an overall eyeball tracking area of the target interface, and the overall eyeball tracking area includes an independent eyeball tracking area of each object in the one or more objects;

and S1802, determining the layout of the eyeball tracking virtual screen according to at least one eyeball tracking evaluation record of at least one object, wherein the eyeball tracking evaluation record comprises a confirmation result used for reflecting the accuracy of a current object selection result of a user, and the current object selection result refers to an object selected by the user and determined according to the eyeball tracking data acquired at the current time.

The target interface may be an interface in any one of the schematic diagrams in fig. 2 to 14.

The format of the eyeball tracking evaluation record may be { (application identifier), (interface identifier), (object identifier), (gaze location), (determination result of whether the object selection result is accurate), and this is not limited uniquely here.

Specifically, the at least one eye tracking evaluation record of the at least one subject includes any one of the following (1), (2) and (3):

(1) for example, a user continuously enters 3 digital passwords through eye tracking, and the terminal determines that the confirmation result is accurate through a playback mechanism and an interactive confirmation mechanism, so that the overall eye tracking area and the individual eye tracking area of each object are reduced, as shown in the example of fig. 9. It can be understood that the playback mechanism and the interactive confirmation mechanism corresponding to the branch may be applicable to an application scenario in which the layout of the eye tracking virtual screen is dynamically adjusted in real time, and may also be applicable to an application scenario in which the layout of the eye tracking virtual screen is adjusted in non-real time, which is not limited herein.

(2) For example, the user tracks each input 1 digital password through the eyeballs, the terminal determines the confirmation result to be accurate through the playback mechanism and the interactive confirmation mechanism, and reduces the overall eyeball tracking area and the individual eyeball tracking area of each object, as shown in fig. 10 or fig. 11 by way of example. It can be understood that the playback mechanism and the interactive confirmation mechanism corresponding to the branch may be applicable to an application scenario in which the layout of the eye tracking virtual screen is dynamically adjusted in real time, and may also be applicable to an application scenario in which the layout of the eye tracking virtual screen is adjusted in non-real time, which is not limited herein.

(3) For example, the terminal stores and updates the eye tracking evaluation records corresponding to the objects, and if 100 records are used as the update adjustment period, when the terminal stores 100 eye tracking evaluation records, the terminal can analyze the use habit of eye tracking of the user according to the confirmation result of the 100 eye tracking evaluation records and adapt and adjust the layout of the eye tracking virtual screen. It can be understood that the playback mechanism and the interactive confirmation mechanism corresponding to the branch are suitable for an application scenario in which the layout of the eye tracking virtual screen is adjusted in non-real time.

In one possible example, the determination policy of the layout of the eye-tracking virtual screen includes:

if the confirmation result in the at least one eyeball tracking evaluation record of the at least one object is accurate, or the number of records with the accurate confirmation result is greater than the number of records with the inaccurate confirmation result, or the number of records with the inaccurate confirmation result is less than a preset number, the size of the whole eyeball tracking area is reduced, and/or the size of the independent eyeball tracking area of the object in the at least one object is adjusted;

if the confirmation result in the at least one eyeball tracking evaluation record of the at least one object is inaccurate, or the number of records with the accurate confirmation result is smaller than the number of records with the inaccurate confirmation result, or the number of records with the inaccurate confirmation result is larger than a preset number, the size of the whole eyeball tracking area is increased, and/or the layout of the independent eyeball tracking area of the object in the one or more objects is adjusted.

The preset number may be 2 or 3 preset values, which is not limited herein.

The object in the at least one object may be all objects (as in fig. 9), may also be an object currently determined to be accurate (as in fig. 11), and may also be an object currently determined to be accurate and an adjacent object of the object (as in fig. 14). It should be noted that, the present application is not limited to the degree of adjustment of the overall eyeball tracking area, the selection of the object to be adjusted, and the degree of adjustment of the object selected for adjustment, and it should be understood that any specific algorithm of the degree of adjustment of the overall eyeball tracking area, the specific strategy of selection of the object to be adjusted, and the specific algorithm of the degree of adjustment of the individual eyeball tracking area of the object selected for adjustment all belong to the specific implementations that can support the application of the present application. The algorithms and strategies described above are briefly described below by way of example only.

For example, the specific algorithm for the degree of adjustment of the overall eye tracking area may determine to be increased by 20%, for example, according to the inaccuracy of the result of the confirmation of the at least one eye tracking evaluation record of the at least one object, where 20% is a preset value.

For another example, a specific policy for selection of an object that needs to be adjusted may be preset to adjust all objects, or only adjust a current object, and the like.

For another example, the adjustment step size may be set to 5% for the degree of adjustment of the object selected for adjustment, for example, 2 consecutive times of inaccuracy, and the individual eye tracking area of the current object is adjusted to be smaller by 5%.

In addition, the adjustment mode may be a multi-directional synchronous adjustment, a one-directional adjustment, or the like, and may specifically be adapted according to the characteristics of the region where the object is located.

Therefore, in this example, the terminal can directly adjust the layout of the eyeball tracking virtual screen according to the confirmation result of the eyeball tracking evaluation record, so as to better adapt to the eyeball tracking use habit of the user and improve the object selection accuracy and the success rate of the target interface.

In one possible example, the determination policy of the layout of the eye-tracking virtual screen includes: determining an eyeball tracking recognition rate according to at least one eyeball tracking evaluation record of the at least one object, wherein the eyeball tracking recognition rate comprises the eyeball tracking recognition rate of the target interface and/or the eyeball tracking recognition rate of a single object; and adjusting the layout of the eyeball tracking virtual screen according to the eyeball tracking recognition rate.

Specifically, for a case where the eyeball tracking recognition rate includes an eyeball tracking recognition rate of the target interface, the eyeball tracking recognition rate of the target interface reflects the overall reasonableness of the layout of the eyeball tracking virtual screen of the target interface to some extent, in this case, the adjusting of the layout of the eyeball tracking virtual screen may be adjusting the overall eyeball tracking area of the target interface and the individual eyeball tracking area of each object, and an example calculation formula may be adjusting the overall eyeball tracking area of the target interface and the individual eyeball tracking area of each object

Where S is the (whole or independent) eye tracking area size, S0 is the preset eye tracking area size (e.g. screen size), β is the calculated eye tracking recognition rate, and β 0 is the preset empirical value of tolerable eye tracking recognition rate.

Specifically, for the case where the eye tracking recognition rate includes an eye tracking recognition rate of a single object, the eye tracking recognition rate of the single object reflects the reasonableness of the distribution of the individual eye tracking areas of the single object and the adjacent objects to some extent, that is, if the eye tracking recognition rate of one object is very low, it indicates that the user actually wants to select the possibly adjacent objects, in this case, the adjusting of the layout of the eye tracking virtual screen may be adjusting the individual eye tracking areas of the single object that is mistakenly selected and the adjacent objects of the single object that is mistakenly selected. The algorithm of the branch adaptation may be more refined, and may specifically determine, according to the recognition rate, an amount of decrease of the individual eye tracking area of the single object that is mistakenly selected and a first adjustment direction, and determine an amount of increase of the individual eye tracking area of the adjacent object of the single object that is mistakenly selected and a second adjustment direction, where the first adjustment direction and the second adjustment direction may be the same, and the adjacent object may be one or more, as shown in fig. 14, which is not limited herein.

Therefore, in this example, the terminal can calculate the eyeball tracking recognition rate according to at least one eyeball tracking evaluation record, and adjust the layout of the eyeball tracking virtual screen according to the eyeball tracking recognition rate, so that the eyeball tracking virtual screen is more adaptive to the use habit of the user for eye tracking, and the success rate and accuracy of object selection are improved.

In one possible example, the eye tracking evaluation record further includes a gaze point position of the user's eye determined according to the currently collected eye tracking data; the determination strategy of the layout of the eyeball tracking virtual screen comprises the following steps: and adjusting the layout of the eyeball tracking virtual screen according to the gazing point position and the confirmation result in the at least one eyeball tracking evaluation record of the at least one object.

It can be understood that the gazing point position can accurately reflect the control information of the user in the actual eye tracking control operation, so that the accuracy of adjusting the direction can be obviously improved by introducing the gazing point position into the adjustment of the layout of the eye tracking virtual screen. It should be understood that the idea of adjusting the layout of the eye tracking virtual screen according to the gazing point position and the confirmation result disclosed in the embodiment of the present application may be adapted to any specific algorithm for adjusting the layout according to the gazing point position and the confirmation result, and is not limited herein.

For example, for a current object, a mean position of a gaze point position determined to be accurate is calculated, a shortest distance between the mean position and a gaze point position determined to be inaccurate is calculated, and independent eye tracking areas of the current object and an adjacent object are adjusted according to a circular area with the mean position as a center of a circle and the shortest distance as a radius.

And calculating the distribution characteristic of the gaze point positions with inaccurate confirmation results according to the target interface, and adjusting the overall eyeball tracking area according to the distribution characteristic, wherein the gaze point positions with inaccurate confirmation results are enlarged towards the left side if all the gaze point positions are in the left area.

For another example, for each object, determining the actual eyeball of the user to watch the reference area according to the watching point position and the confirmation result; and determining a position error according to the actual eyeball fixation reference area of the user and the original independent eyeball tracking area, and adjusting the layout according to the position error.

Therefore, in this example, the terminal can more accurately analyze the human eye tracking use habit of the user according to the gaze point and the confirmation result, so that the layout of the eyeball tracking virtual screen is more accurately adjusted.

In one possible example, the determination policy of the layout of the eye-tracking virtual screen includes: classifying the at least one eyeball tracking evaluation record of the at least one object according to the difference of the layout to obtain at least one eyeball tracking evaluation record set with the same layout; calculating the recognition rate of the current layout aiming at each eyeball tracking evaluation record set with the same layout; screening out a reference layout with the recognition rate greater than a preset recognition rate; generating sample data according to the reference layout and features of the objects of the target interface, the features including at least one of: quantity and recognition rate; training a preset eyeball tracking virtual screen layout model by using the sample data to obtain an updated eyeball tracking virtual screen layout model; predicting a layout of the eye tracking virtual screen of the target interface using the eye tracking virtual screen layout model.

The eyeball tracking virtual screen layout model may be any type of neural network model, such as a convolutional neural network model, and the like, which is not limited herein.

Specifically, the at least one eyeball tracking evaluation record can acquire data of interfaces of the same type of mobile phones of other users through cloud interaction, so that the comprehensiveness of the data is increased, and the model can be trained to have the capability of adapting to the common use habit of the user group.

Specifically, the at least one eye tracking evaluation record may not be limited by the constraint of the interface type, that is, may be data of any functional interface, so that the universality of the trained model may be expanded.

As can be seen, in this example, the terminal can predict and adjust the layout of the eyeball-tracking virtual screen of the target interface based on the AI model.

In one possible example, a side frame of the terminal to which the screen belongs is provided with a plurality of spot lights, each spot light is used for emitting a specific color to indicate an expansion area, the expansion area is used for guiding a user to use an eyeball tracking function to realize object selection, and irradiation areas of any two spot lights are independent of each other.

As shown in fig. 1D, the colors of the respective lamps can be set differently.

In one possible example, the confirmation result for reflecting whether the user selects the result for the current object is determined by a playback mechanism and an interactive confirmation mechanism; the playback mechanism comprises any one of the following mechanisms: highlighting the selected object, highlighting the independent eye tracking area of the selected object, and floating the selected object; the interactive confirmation mechanism comprises any one of the following: displaying a first image and a second image in a suspended mode on the target interface, and generating a confirmation result according to selection operation of the first image or the second image; generating a confirmation result according to the blinking times of the user in a preset time period; and generating a confirmation result according to the event that the user presses the preset physical case.

Specifically, examples of the playback mechanism are shown in fig. 6, 8, and 9, and examples of the interaction confirmation mechanism are shown in fig. 10, 12, and 13.

In addition, it should be noted that, in the exemplary scheme described in the embodiment of the present application, the individual eye tracking areas of the objects are all actual display areas (if the objects are visual objects) containing the current object, but it can be understood that there is no position constraint relationship between the individual eye tracking areas and the actual display areas, and even the individual eye tracking areas of one object may include actual display areas of 2 objects, and how to distribute the individual eye tracking areas is determined dynamically by the terminal according to the eye tracking evaluation records, and is not understood as having any position constraint relationship.
