Detailed Description
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are merely for explaining the technical principles of the present invention, and are not intended to limit the scope of the present invention.
FIG. 1 is a schematic diagram of the main steps of a first embodiment of the target predictive thinking evaluation method of the present invention. As shown in fig. 1, the evaluation method of the present embodiment includes steps S10 to S20:
And step S10, controlling the observed object to move and disappear on the display screen according to the movement parameters, simultaneously acquiring the eye movement track of the tested person in the process of observing the object, and acquiring the judgment value of the tested person on the position of the object at the moment of finishing the observation.
Wherein the movement parameters include: the movement duration and/or the movement speed and/or the movement acceleration and/or the movement direction of the object and/or the angular offset before the object disappears, etc.
In practical application, the "observation end time" may be given by the evaluation system or by the testee. For example, the evaluation system may give a prompt tone after the target object disappears and reaches a preset time (for example, 2 seconds) (i.e., the end time of observation), so as to request the tested person to click the position that the target object may reach at the moment in the screen, and at this moment, obtain the clicked position of the tested person as the judgment value of the tested person on the position of the target object; or the evaluation system draws a designated area on the screen in advance, when the tested person judges that the target object reaches the designated area after the target object disappears, the designated button in the screen is actively pressed, the pressed time of the designated button is the observation ending time, and the central position of the designated area is obtained at the moment to be used as the judging value of the tested person to the position of the target object.
Specifically, the step of "acquiring an eye movement track during observation of the object by the subject" may include: and recording an eye movement track curve of the human eyes from the beginning of the test to the disappearance of the target object by using an eye movement instrument until the whole process is observed. The difficulty of testing may be increased or decreased by adjusting the movement parameters and/or the size of the designated area.
And step S20, generating an evaluation result according to the actual movement track of the target object, the eye movement track and the judgment value of the tested person on the position of the target object at the observation end time.
Wherein, the evaluation result comprises: observation ability and predictive ability of the subject, and the like.
In this embodiment, step S20 may include steps S21 to S22:
Step S21, discrete point extraction is respectively carried out on the actual movement track and the eye movement track of the target object based on a plurality of identical time points;
and S22, calculating the coordinate difference of the discrete points at each time point respectively, and further generating an evaluation result.
When the target moves on the screen, the movement track of the target is displayed as a two-dimensional curve on the screen, and each point on the movement track can obtain corresponding horizontal and vertical coordinate values (x, y). In the process of tracking after the disappearance of the target object, the displacement track of the human eye on the screen, namely the eye movement track, can be recorded by an eye movement instrument, and the track point can also obtain corresponding horizontal and vertical coordinate values (x ', y'). Corresponding position coordinate information is extracted from the actual movement track of the target object and the eye movement track at a plurality of same time points, and then coordinate differences of the actual movement track discrete points of the target object and the eye movement track discrete points at the same time points are calculated, so that the deviation situation of the actual movement track of the target object in the human eye tracking process can be judged, and an evaluation result is obtained.
The selection of discrete points and the calculation of evaluation results can adopt a plurality of different methods according to actual needs. Example 1: n equally divided time points can be selected from the observation starting time to the observation ending time, discrete points are extracted from the actual movement track and the eye movement track of the target object respectively, N pairs of coordinate values are obtained, and then the observation capability score and the prejudgment capability score of the tested person can be calculated according to formulas (1) and (2) respectively:
Wherein S 1 and S 2 are the observability score and the predictive ability score of the tested person, respectively; (x n,yn) is the coordinate value of the nth discrete point selected on the actual motion track of the target object; (x' n,y′n) is the coordinate value of the nth discrete point selected on the eye movement track; the (x N,yN) and (x' N,y′N) are the actual motion track of the target object and the coordinate value of the discrete point on the eye motion track corresponding to the observation end time, and can be understood as the actual value of the position of the target object at the observation end time and the judgment value of the tested person on the position of the target object. The extraction quantity of the discrete points can be correspondingly adjusted according to the movement speed, the movement distance, the test time and the like of the target object.
Example 2: n time points (such as when the curvature of the track is the largest, when the speed is the fastest, and the like) can be selected according to the characteristics of the actual motion track of the target object, and discrete points are extracted from the actual motion track of the target object and the eye motion track respectively to obtain N pairs of coordinate values. In addition, the weight value of the coordinate difference at each time point may also be considered in calculating the observability and the prejudgement ability of the subject.
In practical application, a corresponding prejudicial thinking report can be formed according to the observation capability, the prejudicial capability and the like of the tested person, and the tested person can train and improve the prejudicial thinking of the tested person in a targeted manner according to the prejudicial thinking report.
In the above embodiments, the movement parameters are preset, and in the following embodiments, the movement parameters may be selected by a tester such as an athlete.

step S5, selecting the movement parameters of the target object.
Those skilled in the art will understand that in practical application, the selection of the movement parameters may be performed manually and input into the evaluation system, or the selection may be performed automatically by the evaluation system according to a certain rule.
Fig. 3 is a schematic diagram of the main steps of a third embodiment of the target predictive thinking evaluation method of the present invention. As shown in fig. 3, in addition to steps S5, S10, and S20, the present embodiment further includes:
And S1, selecting an evaluation mode.
The evaluation modes comprise a single evaluation mode and a multi-person evaluation mode.
When the selected evaluation mode is the multi-person evaluation mode, the method further comprises, after step S22:
And S23, respectively comparing the observation capability and the prejudgment capability of a plurality of testees participating in evaluation at the same time to generate a comparison result.
At this time, the finally generated evaluation result includes the comparison result in addition to the observation capability and the predictive capability of each of the testees.

and step S30, storing and displaying the evaluation result.

Fig. 5 is a schematic diagram of the main steps of a fifth embodiment of the target predictive thinking evaluation method of the present invention. As shown in fig. 5, the present embodiment shows the main flow of the target predictive thinking evaluation method of the present invention in the multi-person evaluation mode.
In order to better compare the target predictive thinking of each tested person, the same target object motion parameters can be set for each tested person in a multi-person evaluation mode so as to ensure that the test conditions are completely the same.
In an alternative embodiment, in order to represent the antagonistic characteristic of the multi-person evaluation and increase the interest of the evaluation, besides obtaining the judgment value of each tested person on the coordinates of the target object at the end of observation, the antagonistic performance of the multi-person test can be increased by setting an intermediate selection link. I.e. when the target object disappears, before the end time of observation, a prompt tone is sent out once or a plurality of times, so that each tested person judges and selects the current position of the target object, and the corresponding judgment value is obtained. In this case, it is necessary to take these discrete points selected in the middle into consideration also when calculating the observation force and the predictive force score for each subject.
