Embodiment two
The present embodiment provides a kind of head-mounted display apparatus on the basis of the above embodiments, the head-mounted display apparatus
It further include display screen and eyeball tracking mould group provided by the embodiment of the utility model including eyepiece.
The eyepiece of the head-mounted display apparatus can be set at the first end face position of eyeball tracking mould group, and display screen can
To be arranged at eyeball tracking mould group second end face position, wherein the shell of eyeball tracking mould group, which can be set into, wears display
The shell of equipment, head-mounted display apparatus provided in this embodiment is by integrating eyeball tracking provided by the embodiment of the utility model
Mould group can also reduce eyepiece institute it is possible to prevente effectively from the aberration and stray light that wearing spectacles user is introduced due to glasses reflection
Caused aberration promotes hot spot image quality.
Further, in this embodiment display screen is configured to various dimensions display screen, the various dimensions display screen is for showing
Various dimensions image.
Optionally, display screen is that can show various dimensions image display panel, specifically, various dimensions display screen can select 3D aobvious
The LCD display that display screen or muti-piece stack.
The picture that the various dimensions display screen is used to prevent head-mounted display apparatus from showing causes vision influx to adjust conflict
(i.e. VAC phenomenon), spinning sensation caused by this phenomenon are virtually to show the bottleneck for being difficult to break through faced at present.When we are seeing
When certain point, eyes rotation makes viewpoint fall corresponding position on the retina, and when seeing object nearby, eyes are usually inside
It sees, sees that the object optical axis of distant place can dissipate, this generates vision influxs；When we see the material object in reality, in addition to view
Feel that influx is adjusted, it is also necessary to dioptric conciliation be carried out to the light of different distance, focusing light rays on retina could be at clearly
Picture.The process that crystalline lens focuses on object during this is called focal adjustments.And the light that screen issues is there is no depth information,
The focus of eyes is just determined on the screen, thus the focal adjustments of eyes and the depth feelings that screen is shown are unmatched, to produce
Raw vision influx adjusts conflict (VAC phenomenon), and this conflict is to disagree with the daily physiological law of the mankind, therefore just have
