It is formed based on the above mechanical structure and hardware, a kind of embodiment of visual training method is provided, as shown in figure 15, packet
Include following steps:
S1, list is established in the server of access Internet, the input condition of list includes the refractive power of eyeball, list
Output result includes the near point position and far point position for visual training；It is for the cognition for cooperating people universal, people are ripe
Specific value of the myopia degree known as refractive power, that is, the degree worn glasses.Establishing list, detailed process is as follows:
S1a, the refractive power for obtaining the second eyeball；Object of second eyeball as sampling, HMD device need to know its dioptric
There is the key for allowing client that refractive power is arranged or HDM equipment to be connect by bluetooth module with smart machine for power, HDM equipment, example
Such as mobile phone, PDA, laptop, tablet computer, user input the refractive power of oneself eyeball on intelligent devices；
S1b, near point calibration: control display screen is mobile to lens and signal is halted in waiting, and display is stopped when signal is halted in acquisition
Shield and is the second near point position by the location position of display screen at this time.Second near point position is specially when display screen is near point
Coordinate, hereinafter referred to as near point coordinate control the position of display screen by then passing through the rotation of motor, so first setting to display screen
A fixed zero point coordinate.When demarcating near point, display screen revert to dead-center position, and processor controls motor rotation and start recording
The turnning circle of motor, when signal is halted in acquisition, the turnning circle of motor is converted between zero point and near point by motor stalling
Distance, near point coordinate is further calculated；
S1c, far point calibration: control display screen is far from lens and signal is halted in waiting, and display is stopped when signal is halted in acquisition
Shield and is the second far point position by the location position of display screen at this time.Second far point position is specially when display screen is in far point
Coordinate, hereinafter referred to as far point coordinate.When demarcating far point, display screen revert to dead-center position, and processor controls motor rotation simultaneously
The turnning circle of start recording motor, when signal is halted in acquisition, motor stalling, by the turnning circle of motor be converted into zero point with
Far point coordinate is further calculated in the distance between far point.Halting signal is external input signal, and in this example, HMD is set
Standby one calibration key of upper setting, user is when carrying out far point and demarcating near point punctuate, when feeling that not seeing Chu Shibian clicks
Key is demarcated, processor reads the interrupt signal that key generates, this interrupt signal is to halt signal.In some other examples
In, user oneself provides on intelligent devices to be halted signal or other people is allowed to cooperate oneself to provide and halt signal, smart machine
Signal will be halted to be transferred in HMD device.
S1d, HMD device will obtain near point coordinate far point seat by WiFi module after the refractive power of the second eyeball and calibration
It puts on and reaches server, or smart machine is transmitted them to by bluetooth module, then service is uploaded to by smart machine
Device.Collection of server is to the refractive power of several the second eyeballs, the second near point position and the second far point position.
S1e, server carry out data to the refractive power of several the second eyeballs, the second near point position and the second far point position
Processing, obtains list.The process of data processing specifically, first set interval and precision, such as precision is set as 1 degree, section
It is 100 degree ~ 500 degree, then refractive power should be 100 degree, 101 degree, 102 degree ... .498 degree, 499 degree and 500 degree in list.It adopts
The refractive power collected is generally integer, and if not integer, then the refractive power after rounding up as sampling is for establishing list.
The average value for acquiring the corresponding all near point coordinates of the same refractive power is exported as the near point of list, and far point is also such.
S2, the refractive power for obtaining the first eyeball, obtain corresponding first near point position and the first far point position from list；
Specifically, the first eyeball is the eyeball that user will be trained, and the myopia degree of oneself eyeball is input to HMD and set by user
In standby, this refractive power is uploaded to server by HMD device, therefrom finds corresponding near point coordinate and far point coordinate.
S3, near point training: control display screen moves back and forth between near point and far point；
S4, far point training: control display screen moves back and forth between far point and super far point.Super far point is preset value.
When human eye sees too far and too close object, eyeball will be adjusted, that is, change the protrusion degree of eyeball, but
As soon as there is a distance that eyes be able to be made not have to adjust and can see, this distance is the distance of distinct vision.That is eyes are seen
Object at the apparent distance is to feel most comfortable, be most suitable for normal eye's observation nearby compared with the distance of wisp, just for eyesight
For normal people, the distance of distinct vision is about 250mm, and near-sighted people's distance of distinct vision is less than 250mm, and people's distance of distinct vision of long sight is greater than
250mm.In this example, when display screen is in origin position, the virtual image formed by the content that display screen is shown is at a distance from eyeball
For the distance of distinct vision.The output result of list further includes origin position, in conjunction with a large amount of other users sampled data as list
In origin position corresponding to every kind of refractive power, or according to the sampled data founding mathematical models of a large number of users, obtain mathematics
Formula obtains the origin position in list in the myopia degree input formula of user.
In view of the eyeball of different refractive powers should be more scientific and reasonable by which kind of training method, therefore in list
Exporting in result further includes drill program, and drill program includes the following contents:
Near point is trained and far point is trained alternately, or M2 far point training is carried out after M1 near point training；
In a near point training, display screen moves back and forth N1 times between near point and far point；
In a far point training, display screen moves back and forth N2 times between far point and super far point；
After each near point training, display screen is moved to origin and stops T1 seconds；
After each far point training, display screen is moved to origin and stops T2 seconds；
In near point training, display screen is at the uniform velocity moved, movement speed V1；
In far point training, display screen is at the uniform velocity moved, movement speed V2.
Drill program in list is generated by following steps: formulating one respectively for multiple first eyeballs of same refractive power
Training effect is preferably used as drill program corresponding to this refractive power in list by a initial training plan.
In some other examples, customer data base is established, includes User ID and and User ID in customer data base
Associated near point coordinate, far point coordinate, origin position, refractive power and drill program.User is instructed using HMD device at the beginning
When practicing, the refractive power of oneself eyeball is inputted, HMD device obtains corresponding near point coordinate, far point coordinate, origin position from list
And drill program, and these are used for trained parameter and User ID and is bound, later user directly inputs the ID of oneself with regard to straight
It connects and is trained using these training parameters.
Since the eye spacing of each user is not quite similar, so obtaining the eye spacing of user simultaneously in some other examples
It is associated with User ID；It carries out adjusting the distance between two visual components according to the eye spacing of user first when visual training, depending on
Feel that component includes lens subassembly and display component.
