FIG. 2 shows a schematic diagram of a test card according to one embodiment of the present application. As shown in fig. 2, the diopter test chart includes a normal diopter area, a large diopter area and a small diopter area which are not overlapped with each other. For example, the normal diopter area may correspond to characters or pictures of a normal font, the larger diopter area corresponds to characters or pictures of an enlarged font, and the smaller diopter area corresponds to characters or pictures of a reduced font.
The positions of the non-overlapping normal diopter area, the partial large diopter area and the partial small diopter area in the diopter test chart card can be distributed in sequence from top to bottom, can also be distributed in sequence from left to right, and can also be distributed in sequence from top to bottom, left to right and the like.

In this embodiment, whether the user is a created user may be determined by one or more of iris, face, fingerprint, or voice recognition of the user. And if the user is the created user, further judging whether diopter values of the user are stored, and if the user is not the created user, creating a new user.
In the case where the user is a created user, the user may send an instruction whether to perform diopter adjustment by any one of the following means: remote control, facial expression, voice, gestures, eye tracking, or blinking, etc. The head-mounted equipment responds to an instruction for diopter adjustment sent by the user in any one of the manners, and diopter adjustment is started; or in response to a user sending an instruction to not perform diopter adjustment in any of the above manners, exiting diopter adjustment.
Fig. 4 shows a flow chart of another diopter adjustment method of a head-mounted device according to an embodiment of the present application. As shown in fig. 4, the method includes:
in step S410, the head mounted device determines whether the user is a created user.
After a user wears a head-mounted device such as VR/AR and opens the head-mounted device manually or in a sensor detection mode, the head-mounted device identifies whether the user is a created user through iris, face, fingerprint or voice. If yes, confirming that the user is a created user, and entering step S420; if not, the user is confirmed to be a new user, and the process proceeds to step S401 to create a new user.
Step S420, determine whether the user has stored diopter value.
If yes, confirming the stored diopter numerical value of the user, and entering step S402, namely automatically adjusting the diopters of the eyepieces on the two sides according to the stored diopter numerical value of the user; if not, it is confirmed that the diopter value of the user is not stored, and the process proceeds to step S430.
Step S430, prompting the user whether to perform diopter adjustment.
The user may send an instruction whether to perform diopter adjustment by any of the following means: remote control, facial expression, voice, gestures, eye tracking, or blinking, etc. For example, in a preset time, if the number of blinks of the user is a single number, it indicates that the user instructs not to perform diopter adjustment, and if the number of blinks of the user is a double number, it indicates that the user instructs to perform diopter adjustment.
If the user sends the diopter adjustment instruction through any one of the above manners, the process goes to step S440, and the head-mounted device goes to the diopter adjustment process; if the user sends an instruction not to perform diopter adjustment in any of the above manners, the process proceeds to step S403, and the head set exits diopter adjustment.
And step S440, displaying the diopter test chart in the display area corresponding to the left eyepiece, and not displaying the diopter test chart in the display area corresponding to the right eyepiece.
Step S450, under the current diopter value of the left ocular, the current focusing position of the user eyeball in the diopter test chart is obtained, and whether the current diopter value meets the visual requirement of the user is judged according to the current focusing position of the user eyeball.
The diopter test chart card comprises a normal diopter area, a large diopter area and a small diopter area which are not overlapped with each other. In the test process, the user is prompted to watch a clearly visible position, and eyeballs of the user are tracked. And judging whether the current focusing position of the eyeball of the user in the diopter test chart corresponds to the position of the normal diopter area or not according to the eyeball tracking, if so, judging that the current diopter value meets the visual requirement of the user, and entering the step S480. If not, the current diopter value is judged not to meet the visual requirement of the user, and the step S460 is entered.
And step S460, performing diopter first adjustment on the determined diopter adjustment direction, and judging whether the adjusted diopter value meets the visual requirement of the user.
In the determined diopter adjustment direction, for example, the diopter adjustment direction is determined such that the distance between the second lens and the display screen is increased by the distance step a each time. The adjustment mode may be that the positions of the first lens and the display screen are kept unchanged, the second lens is gradually adjusted by the electric motor to move leftward, or the positions of the first lens and the second lens are kept unchanged, the display screen is gradually adjusted by the electric motor to move rightward, the distance between the second lens and the display screen is increased by the distance step a each time, and the distance L2 between the second lens and the display screen is adjusted to be a + a from the distance a corresponding to the current diopter value.
After diopter is adjusted for the first time, the user is prompted to watch a clearly visible position, and eyeballs of the user are tracked. And judging whether the current focusing position of the eyeball of the user in the diopter test chart corresponds to the position of the normal diopter area or not according to the eyeball tracking, if so, judging that the current diopter value meets the visual requirement of the user, and entering the step S480. If not, judging that the current diopter value does not meet the visual requirement of the user, and entering step S470 for further diopter adjustment.
And step S470, performing diopter nth adjustment on the determined diopter adjustment direction, and judging whether the adjusted diopter value meets the visual requirement of the user.
For example, the positions of the first lens and the display screen are kept unchanged, the second lens is adjusted by the electric motor for multiple times to move leftwards, the distance between the second lens and the display screen is increased by the distance step a every time, and the distance L2 between the second lens and the display screen is adjusted to be A + n a from the distance A corresponding to the current diopter value. After diopter adjustment every time, the user is prompted to watch a clearly visible position, and eyeballs of the user are tracked. And judging whether the current focusing position of the eyeball of the user in the diopter test chart corresponds to the position of the normal diopter area or not according to the eyeball tracking until the current diopter value is judged to meet the visual requirement of the user, and entering the step S480.
And step S480, storing the diopter value after the last adjustment as the diopter corresponding to the user on the left eyepiece, completing the diopter adjustment of the left eyepiece, and switching to the right eyepiece to perform diopter adjustment according to the steps S440 to S470.
