In view of the above-mentioned drawbacks of the prior art, the present invention provides a method for focus training based on visual tracking, the method comprising: playing a video scene for concentration training, generating a virtual barrier in the video scene, and acquiring visual tracking time length generated by a user based on the virtual barrier; extracting virtual throwing objects from a preset virtual throwing object pool according to the visual tracking time length, wherein different virtual throwing objects have different influences on the existence time length of the virtual obstacle respectively; acquiring throwing selection information of the user, and updating the existing time length according to the throwing selection information and the extracted virtual throwing object; judging whether the updated time length is zero, if not, randomly transforming the position of the virtual obstacle, and continuously executing the step of obtaining the visual tracking time length of the user until the time length is zero; and acquiring the whole duration consumed by zeroing the existing duration, and determining the shape and the size of the new virtual obstacle generated next time according to the whole duration. The problem of among the prior art based on the eye tracking concentration training method usually adopt the visual tracking card to train child's eyeball to chase after the ability and concentration, nevertheless the visual tracking card can't the dynamic adjustment training degree of difficulty, leads to training effect limited is solved.
As depicted in fig. 1, the method comprises:
step S100, playing a video scene for concentration training, generating a virtual barrier in the video scene, and acquiring a visual tracking time length generated by a user based on the virtual barrier;
step 200, extracting virtual throwing objects from a preset virtual throwing object pool according to the visual tracking time length, wherein different virtual throwing objects have different influences on the existence time length of the virtual obstacle respectively;
step S300, obtaining throwing selection information of the user, and updating the existing time length according to the throwing selection information and the extracted virtual throwing object;
step S400, judging whether the updated time length is zero, if not, randomly transforming the position of the virtual obstacle, and continuously executing the step of obtaining the visual tracking time length of the user until the time length is zero;
and S500, acquiring the whole duration consumed by zeroing the existing duration, and determining the shape and the size of the new virtual obstacle generated next time according to the whole duration.
Specifically, first, a user will watch a section of play video, and the play video will show the virtual character and the specific video scene corresponding to the user. The terminal can generate virtual barriers in the video scene according to a preset time interval or in a random mode when playing the video. When the virtual obstacle is generated, the terminal can acquire the time spent from the viewpoint of the user to track the virtual obstacle, and the visual tracking time is obtained. The user's concentration training task is to eliminate the virtual obstacle, i.e., to zero the duration of the virtual obstacle. The visual tracking time length can reflect the response speed of the user, the terminal can extract virtual throwing objects from the virtual throwing object pool according to the preset reward and punishment system based on the visual tracking time length, the virtual throwing objects can be attacks such as hammers and stones, and the existence time length of virtual barriers can be reduced; the virtual throwing object can also be a cure object such as a band-aid and love, and the existence time of the virtual barrier can be prolonged. The user needs to correctly judge whether to throw the virtual throwing object according to the extracted virtual throwing object. After receiving the selection information made by the user, the terminal updates the existence time of the virtual throwing object according to the selection information of the user. If the updated existing time length is not zero, the current virtual obstacle is not eliminated, and training is continued. Randomly transforming the positions of the virtual obstacles, and repeating the steps until the existing time length of the current virtual obstacle is zero, namely, the current virtual obstacle is eliminated. The terminal can evaluate the current concentration value and the response speed of the user according to the whole duration consumed by zeroing the existing duration, and the shorter the whole duration is, the higher the current concentration value of the user is, and the faster the response is. And then the training difficulty of the concentration training is dynamically adjusted according to the overall duration, the adjustment of the training difficulty is mainly reflected in the adjustment of the shape and the size of the virtual obstacle, and the larger the shape of the virtual obstacle, the lower the training difficulty is, and otherwise, the higher the training difficulty is. Through the dynamic adjustment training degree of difficulty in the concentration training, can effectively promote user's training effect.
In one implementation manner, when the screen area is smaller than or equal to the preset area value, the acquiring the visual tracking duration of the user specifically includes:
step S101, acquiring a facial image of the user, and determining the pupil position of the user according to the facial image;
step S102, determining the viewpoint position corresponding to the user on a screen according to the pupil position;
and step S103, taking the time spent by the viewpoint position reaching the position of the virtual obstacle as the visual tracking time.
For a small screen, the tracking range of the user is small, and thus the viewpoint position can be determined by detecting the pupil position of the user. Specifically, a photographing device is provided in advance on a screen, and a face image of a user is acquired by the photographing device. The facial image is analyzed and the pupil position of the user is determined by gray level detection. Since the relative positional relationship of the user to the screen is known, the pupil position can be converted into the viewpoint position of the user on the screen. When the viewpoint position falls into the region where the virtual obstacle is located, judging that the user viewpoint reaches the virtual obstacle, and then calculating the time spent in the process to obtain the visual tracking time.
In another implementation manner, when the screen area is greater than the preset area value, the acquiring the visual tracking duration of the user specifically includes:
step S104, acquiring the rotation direction and the rotation angle of the head of the user;
step S105, determining the viewpoint position corresponding to the user on the screen according to the rotation direction and the rotation angle;
and step S106, taking the time spent by the viewpoint position reaching the position of the virtual obstacle as the visual tracking time.
For a large screen, the tracking range of the user is large, and thus the viewpoint position needs to be determined by the movement condition of the user's head. Specifically, the user wears a specific detecting device on the head in advance for acquiring the rotation direction and rotation angle of the head. And then determining the face orientation of the user according to the rotation direction and the rotation angle, and determining the viewpoint position of the user on the screen according to the face orientation and the predetermined relative position relationship between the user and the screen. When the viewpoint position falls into the region where the virtual obstacle is located, judging that the user viewpoint reaches the virtual obstacle, and then calculating the time spent in the process to obtain the visual tracking time.
According to the embodiment, different viewpoint positions are distributed to screens with different sizes, so that the accuracy of viewpoint positioning can be effectively improved, and further reliable visual tracking time is obtained.
In one implementation, the virtual throwing object pool includes an aggressor pool and a curative pool, and the step S200 specifically includes:
step S201, determining extraction probabilities corresponding to the aggressor pool and the healer pool respectively according to the visual tracking time length, wherein the aggressor pool comprises a plurality of aggressors for reducing the existence time length, and the healer pool comprises a plurality of healers for increasing the existence time length;
step S202, randomly extracting the virtual throwing objects from the virtual throwing object pool according to the extraction probabilities respectively corresponding to the attacking object pool and the healing object pool.
Because the visual tracking duration can reflect the response speed of the user, the embodiment sets a reward and punishment system for the visual tracking duration in advance. Specifically, the shorter the visual tracking duration is, the faster the user's reaction is, the greater the probability of extracting an attack object pool is, and the probability of extracting a healing object pool is small; the longer the visual tracking time length, the slower the user's reaction, the smaller the probability of extraction of the aggressor pool and the greater the probability of extraction of the healing pool. Because the task of the user is to eliminate the virtual obstacle, only the attacker can reduce the existence time of the virtual obstacle, and the healed object can increase the existence time of the virtual obstacle instead, the extraction probability of the two pools is adjusted through the visual tracking time, which is equivalent to rewarding or punishing the user according to the response speed, thereby integrating the reaction training of the user into the concentration training to obtain a better training effect.
In one implementation, the updating the existing duration according to the throwing selection information and the extracted virtual throwing object specifically includes:
step S301, when the throwing selection information is throwing, updating the existing time length according to the extracted virtual throwing object;
and step S302, when the throwing selection information is not throwing, the current time duration of the virtual obstacle is maintained.
Specifically, after receiving selection information input by a user, the terminal indicates that a life value of a virtual obstacle needs to be updated based on a virtual throwing object generated at present if the selection information is throwing; if the selection information is not thrown, the virtual throwing object generated at present is invalid, and the current life value of the virtual obstacle is maintained.
In one implementation, the randomly transforming the position of the virtual obstacle includes:
step S401, determining a transformation distance according to the visual tracking time length, wherein the visual tracking time length and the transformation distance are in inverse proportion;
step S402, randomly transforming the position of the virtual obstacle on the circumference taking the current position of the virtual obstacle as the center and the transformation distance as the radius.
Specifically, the longer the visual tracking duration is, the slower the current response of the user is, and in order to reduce training difficulty, a position is randomly selected to be used as a new appearance position near the original appearance position of the virtual obstacle; the shorter the visual tracking time length is, the faster the current response of the user is, and in order to improve training difficulty, a position is randomly selected from the area far from the original appearance position of the virtual obstacle to serve as a new appearance position of the virtual obstacle. According to the method and the device for dynamically adjusting the random appearance area of the virtual obstacle through the visual tracking time, the problem that a user has poor training effect due to improper training difficulty can be avoided.
In one implementation, the overall duration is proportional to the size of the shape of the new virtual obstacle that is generated next.
Specifically, the overall duration can objectively reflect the current concentration degree of the user, so that the shape and the size of the virtual obstacle generated next time are dynamically adjusted according to the overall duration. The longer the whole duration is, the lower the current concentration degree of the user is, the larger the shape of the new virtual obstacle generated next time is, so that the training difficulty is reduced; the shorter the whole duration is, the higher the current concentration degree of the user is, and the smaller the shape of the new virtual obstacle generated next time is, so that the training difficulty is improved. Thereby avoiding the problem of poor training effect caused by improper training difficulty of users.
