Embodiment be only some embodiments of the present application, and not all embodiment.Based on the embodiment in the application, this field
Those of ordinary skill's all other embodiment obtained without making creative work belongs to the application protection
Range.
Referring to Fig. 1, the embodiment of the present application provides a kind of visual stimulus device based on virtual reality, comprising: VR is aobvious
Show module 1, memory module 3 and visual stimulus control module 2；
Memory module 3 and visual stimulus control module 2 communicate to connect；
VR display module 1 and visual stimulus control module 2 communicate to connect；
Visual stimulus control module 2 includes: space load submodule 21；
Memory module 3 be used for store include visual stimulus source Virtual Space model resource；
Space loading module carries out parsing load for reading Virtual Space model resource, and will complete the three-dimensional after loading
Space model data is sent in VR display module 1 and shows.
It should be noted that needing to develop by virtual reality first before the visual stimulus device using the present embodiment
A Virtual Space Scene containing visual stimulus is erected in tool and is stored in a storage module, and virtual reality technology is passed through
The virtual three dimensional space of generation, user are only acted on for single direction by wearing virtual implementing helmet, opposite traditional equipment,
Receive visual stimulus information by Virtual Space, allows users to be immersed to the comprehensive vision that receives in the virtual environment and pierce
Swash.
Further, the image construction that visual stimulus source is combined by several groups prediction picture shape and preset color.
Further, the image shape in visual stimulus source includes: at least one in a grid, Gabor, gridiron pattern and hot spot
Kind；
The color combination in visual stimulus source includes: that black and white, red green and indigo plant are at least one of yellow.
Further, visual stimulus control module 2 further include: stimulus switching submodule 22；
Stimulus switching module is used to switch in the image shape and color combination in the visual stimulus source in display at least
One.
It should be noted that the visual stimulus image shape that the present embodiment uses includes a grid, Gabor, gridiron pattern and light
Spot, in program operation process, by dynamically switching stimulating image, including color, the temporal frequency to various strong contrasts
With the switching of spatial frequency, rich and varied stimulation form can produce.For example, for every kind of stimulus modality, it can be by fixed
When device clocked flip or by peripheral hardware switch manual trigger stimulating image switching signal, switch the color of strong contrast, as black and white,
Red green, blue Huang etc. is switched to a kind of image of lower shape after three groups of colors have switched, such as switches the image of bar-grating shape shape
At the image of gridiron pattern shape.Switch repeatedly, can permutation and combination go out diversified visual stimulus form.
Further, the brightness of the image after the conversion of three-dimensional space model data is greater than or equal to the first luminance threshold
Value.
Further, the primary contrast of the image after the conversion of three-dimensional space model data is greater than or equal to first
Contrast threshold.
It should be noted that in order to improve the effect of visual stimulus, during scene construction can according to hereinafter, 1,
Light should become clear enough；2, contrast is sufficiently strong；3, visual stimulus object should be placed in user in the position of Virtual Space
The left and right sides, the target that stimulation point is contained in two sides should be apart from 2 meters to 4 meters of user of judge distance range.4, it can be in scene
Floor also rendered using rough visual stimulus texture, such visual effect is easier to make the visual impression of user
Official generates profound impact.
For this purpose, first luminance threshold of the present embodiment and the value preferred scope of the first contrast threshold are 50~100.
Further, visual stimulus control module 2 further include: contrast adjustment submodule 23；
Contrast adjustment submodule 23 is used for the difference according to the binocular vision data got, and the excellent view eye for adjusting user is right
The screen answered displays contrast.
Further, contrast adjustment submodule 23 is specifically used for according to the difference of binocular vision data and the excellent view eye of user
Negative correlativing relation between the displaying contrast of corresponding screen, adjusting display contrast.
Meanwhile when through method of visual activation training eyesight, it will usually cover in healthy eyes, the present embodiment is according to user
The different eyesights of the eyes of input handle the contrast of visual stimulus figure, eyes preferable for eyesight, reduce user
The visual stimulus figure contrast seen, and the eyes poor for eyesight, visual stimulus picture are not processed.For example, left eye regards
Power is 0.1, and right vision 1.0, two eye visions have big difference, and just sets original image for the visual stimulus figure contrast of right eye
10%.If left vision is 0.1, right vision 0.2, two eye visions are not much different, just by the visual stimulus figure pair of right eye
It is set as the 90% of original image than degree, for other vision conditions, the contrast of visual stimulus figure can do linearly related place according to this
Reason, to sum up, i.e. binocular vision gap is bigger, the excellent contrast for regarding the corresponding screen of eye is lower.
It is understood that it is example data, the visual stimulus of the present embodiment that above-mentioned picture contrast, which adjusts numerical value,
Displaying contrast for figure is adjusted with the binocular vision difference of user's input according to negative correlativing relation, i.e. binocular vision gap is bigger,
Displaying contrast for the calculated excellent visual stimulus figure depending on the corresponding screen of eye is then lower.
Further, visual stimulus control module 2 further include: interactive operation submodule 24；
Interactive operation submodule 24 is used to obtain the operational order of user's input.
In addition, improving user experience in order to improve the interest that device uses, the device of the present embodiment further includes handing over
Interoperate submodule 24, and is embedded in interactive operation submodule 24 plug-in unit of game element, by interaction modes such as game,
It makes it possible to preferably be immersed in virtual reality space, eliminates user to the conflict psychology for the treatment of, guidance user more goes to watch attentively
Visual stimulus point in Virtual Space, can obtain better effect of stimulation.
By taking the car race game scene in Fig. 3 as an example, when user puts on virtual implementing helmet, starts visual stimulus mode,
User can be instructed by external input equipment, such as keyboard, game paddle equipment input control, be swum in control racing car
During play, the vision of user is stimulated by the visual stimulus source of the high contrast of the racing track two sides in Virtual Space, simultaneously
The gold coin of positive incentive is placed in the two sides of user's visual fields, guidance user is close in this process and watches stimulation attentively
Point；Or barrier is placed on to the middle position of user's visual fields, and user's avoiding obstacles are guided, it is mobile to two sides.
The virtual three dimensional space that the embodiment of the present application is generated based on virtual reality technology, user is by wearing virtual reality head
Helmet, opposite traditional equipment only act on single direction and compare, and virtual three dimensional space has stronger three-dimensional sense, keeps user complete
Orientation receives visual stimulus, has more obvious raising to the effect of visual exercise, solves existing method of visual activation
The technical issues of visual exercise less effective.
