Description
Technical field
The present invention relates to technical field of virtual reality, a kind of virtual reality device more particularly, to adjustable image distance image height and
Its mobile terminal
Background technique
Virtual reality technology be emulation technology and computer graphics human-machine interface technology, multimedia technology, sensing technology,
The set of the multiple technologies such as network technology is a challenging interleaving techniques front subject and research field.It is virtual existing
Real technology (VR) includes that simulated environment, perception, natural technical ability and sensing set each etc., and simulated environment is generated by computer
, dynamic 3 D stereo photorealism in real time.
The principle for wearing virtual reality device is to amplify image caused by small two-dimension display by optical system.
Specifically, the light that miniscope is emitted generates image similar to distant place effect because of refraction by convex lens.It utilizes
Near objects are amplified to ornamental at a distance and reach so-called full figure vision (Hologram) by this effect.The image of display passes through
One eccentric free-form surface lens, makes image become similar big screen picture.Since eccentric free-form surface lens are one skewed
Concave lens, therefore optically it is not singly lens function, substantially has become scope of freedom prism.When generation image into
Enter eccentric free curved surface prism face, then is all-trans and is incident upon observer's eyes oncoming lane concave surface mirror surface.Side concave surface mirror surface is coated with one layer of mirror
Finishing coat, light is amplified the eccentric free curved surface prism face that reflexes to again simultaneously for reflection, and in face correction Ray obliquity, arrives
Up to observer's eyes.
Current technology, is put into VR (Virtual Reality, i.e. virtual reality) for mobile terminal and wears virtual reality and set
After slot or fixture in standby (HMD, Head Mounted Device), the image distance image height of VR experience is to fix, and user can not
Voluntarily adjust.For the user in VR experience, image distance determine periphery visible oBject to the distance of itself, and image height then with
The similarity degree of periphery visible oBject and real world matters a lot, the two factors largely affect immersing for user
Sense degree.Obviously, technology is unable to satisfy the growing feeling of immersion degree demand of user at present.
Summary of the invention
The shortcomings that for current technology, invention provides a kind of virtual reality device and its mobile terminals, it is intended to solve
