Wherein, the quantity of image capture device 150 can be one, and image capture device 150 is collecting face picture
It afterwards, can be by coordinate of the sight line point included by face picture and current Target Photo in the display equipment 130 one by one
Corresponding caching, forms an alternative pictorial information.Over time, which can take multiple
Face picture, each face picture correspond to different current goal pictures, eventually form multiple alternative pictorial informations and are stored in and deposit
In reservoir 110.
Optionally, in order to accelerate the acquisition speed that sight acquires data, the quantity of image capture device 150 may be more
A, the device coordinate of the opposite display equipment 130 of each image capture device 150 is different.
Under this embodiment, for the same current Target Photo, controller 120 is in control image capture device
It, can be according to the difference of image capture device 150, to obtain multiple face pictures when the face picture of 150 collecting test persons.
Similarly, when being subsequently formed alternative pictorial information, for coordinate of the same sight line point in the display equipment 130, control
Device 120 can obtain alternatively scheming with the one-to-one multiple groups of image capture device 150 according to the difference of image capture device 150
Piece information.
By image capture device 150 collected face picture may be unsatisfactory for forming the requirement of sight data, because
This optionally can also pre-save face orientation mode preset condition in the memory 110.Wherein, the face
Orientation mode preset condition may is that in face picture corresponding with the image capture device 150, face is set with the display
Standby 130 distance is within the scope of pre-determined distance；It is also possible in face picture corresponding with the image capture device 150, people
The direction of face is within the scope of predetermined angle；It is also possible in face picture corresponding with the image capture device 150, human eye is not
It is blocked；It can also be while meeting any two condition in above three condition or all three conditions.
When controller 120 is in the face picture and the current target figure for acquiring some image capture device 150
Coordinate of the corresponding sight line point of piece in the display equipment corresponds caching, is formed before alternative pictorial information, the control
It is default that device 120 processed may determine that whether face picture corresponding with the image capture device 150 meets the face orientation mode
Condition；When meeting, face picture and the current target figure that 120 ability of controller acquires the image capture device 150
Coordinate of the corresponding sight line point of piece in the display equipment 130 corresponds caching, forms alternative pictorial information.It is being unsatisfactory for
When, controller 120 can redefine next current Target Photo, and acquire and survey again through image capture device 150
The face picture of examination person.
Certainly, optionally, controller 120 can also control institute before redefining next current Target Photo
It states display equipment 130 and issues acquisition miscue, so that posture of the tester to oneself is adjusted.The acquisition miscue can
To be to show according to the concrete condition of face orientation mode preset condition is unsatisfactory for for correcting the indicative of tester's posture
Content, such as: " apart from too far, please be close to display equipment ".
Next current Target Photo will be redefined for controller 120 below to be introduced.
As an alternative embodiment, when controller 120 redefines next current Target Photo, it is described
Next current Target Photo can be identical as a upper current Target Photo, i.e., controller 120 can directly be shown again
Show that a current Target Photo is identical.
As another optional embodiment, when controller 120 redefines next current Target Photo, institute
Stating next current Target Photo can be different from a upper current Target Photo.
Under this embodiment, if it includes multiple pictures that Target Photo, which generates data, controller 120 is from the multiple figure
After excluding current Target Photo in piece, determine a picture as next current Target Photo.
Under this embodiment, if Target Photo generate data include a picture, a sight point identification and with
Machine number generating function, next line of sight point coordinate that the available random number generation function of controller 120 generates, thus really
A Target Photo is made as next current Target Photo.
Under this embodiment, if it includes a picture, a sight point identification and more that Target Photo, which generates data,
A sight line point coordinate, controller 120 exclude the view of target corresponding to current Target Photo from the multiple sight line point coordinate
After line point coordinate, a new line of sight point coordinate is determined, so that it is determined that a Target Photo is as described next out
Current Target Photo.
Under this embodiment, if it includes a picture, sight point identification, a random number that Target Photo, which generates data,
Generating function and multiple sight line point coordinates, controller 120 can be after random number generation function generate a random coordinates, will
Random coordinates are added to the point coordinate of line of sight corresponding to current Target Photo, form a new line of sight point and sit
Mark a, so that it is determined that Target Photo is as next current Target Photo out.
Step S130: the controller when getting the sight line point that the sensing apparatus is sent and acquiring signal, from institute
It states at least one corresponding alternative pictorial information of image capture device and determines a Target Photo information.
Wherein, the sight line point acquisition signal can detect tester's finger for the sensing apparatus 140
Or stylus touches generated signal when sight line point, or generated when tester is by mouse click sight line point
Signal.
When controller 120 gets sight line point acquisition signal, from least one acquired with described image acquisition equipment 150
A Target Photo information is determined in alternative pictorial information, may include:
The available sight line point of controller 120 acquires the generation time of signal, after then the generation time subtracting preset value
Obtain comparison time.Preset value characterization test person sees the time interval of triggering sight line point acquisition signal after sight line point, generally
It can be set to 300 milliseconds.Then, at least one alternative pictorial information that controller 120 is acquired from the image capture device 150
In select an alternative pictorial information as the Target Photo information, wherein the holding time of the Target Photo information
It is closest with the comparison time.
Optionally, the controller 120 is detecting that the mouse moves or detect in the display equipment 130
When sliding on the sensing apparatus 140, the controller 120 can also acquire the mouse for the finger or the stylus
The operating position coordinate of mark, the finger or the stylus in the display equipment 130, and using the coordinate as reference
Coordinate is stored in the memory 110.
Certainly, it is worth noting that, if controller 120 detects finger or the stylus on sensing apparatus 140
Sliding, at this point, controller can also detect finger or the stylus in the stop of the same position of sensing apparatus 140
Between, if the residence time is less than the default residence time, operating position coordinate at this time is saved as reference coordinate, if stop
Between be more than the default residence time, then finger or the stylus are long-pressing sensing apparatus 140, and what is triggered at this time is that sight line point is adopted
Collect signal.
Under this embodiment, controller 120 is worked as in the face picture for acquiring the image capture device 150 with described
Coordinate of the corresponding sight line point of preceding Target Photo in the display equipment 130 corresponds caching, forms alternative picture letter
When breath, controller 120 can also by face picture that the image capture device 150 acquires, acquire the face picture when it is corresponding
Reference coordinate and the corresponding sight line point of the current Target Photo it is described display equipment 130 in coordinate correspond
Caching, forms alternative pictorial information.
It is worth noting that sliding shape may be not on due to the finger of stylus or mouse or gathered person
State and cause when acquiring some face picture, be not present reference coordinate corresponding with the time point.At this point, controller 120 can
With in the reference coordinate being saved, the time that will save reference coordinate is right closest to the time point institute for acquiring the face picture
Reference coordinate of the reference coordinate answered as the face picture.Correspondingly, controller 120 is from right with the image capture device 150
When determining a Target Photo information in the alternative pictorial information of at least one answered, controller 120 can be from the Image Acquisition
An alternative pictorial information is selected at least one alternative pictorial information that equipment 150 acquires to believe as the Target Photo
Breath.Wherein, reference coordinate corresponding with the Target Photo information is with sight line point included by the Target Photo information in institute
The distance between the coordinate stated in display equipment 150 is greater than preset value (i.e. reference coordinate is except sight line point coordinate range), and
The holding time of the Target Photo information and the comparison time are closest, and it is mobile not yet can to find testee in this way
But it will be moved into the picture of sight line point, such human eye state most concentrates on sight line point.
Since tester is clicking sight line point triggering generation sight line point acquisition signal with finger or stylus or mouse
When, and the coordinate of point that is contacted of sensing apparatus 140 and the coordinate of the current corresponding sight line point of Target Photo have deviation, because
This is optionally determining a Target Photo from least one alternative pictorial information corresponding with the image capture device
Before information, the judgement of controller 120 triggers the coordinate and the current Target Photo pair of the sight line point acquisition signal
Whether error of the sight line point answered between the coordinate in the display equipment is more than preset error threshold；When to be no, institute
