Description
Technical field
Put the present invention relates to technical field of virtual reality, more particularly to a kind of artificial hip joint based on virtual reality technology
Change art teaching display systems.
Background technology
Virtual reality technology is the multiple signal conduction between virtual scene system, consciousness management system and user, is used
Family incorporates virtual scene.Computer completes the design of virtual scene, makes, and VR equipment realizes the consciousness feedback of user, and this is empty
Intend the content input of reality；User receives perceptual sign and user perception is input into computer by catching equipment, completes scene
Response, this is the signal output of user；Consciousness management system constantly conducts signal between virtual scene system and user, shape
Into complete signal closed loop.But the maximum problem of VR technologies is the foundation of dizzy solution, professional standard at present, is trapped in fecund
The complex fusion of industry, many scenes.
The final purpose of medical education is clinical manipulation, but traditional plane teaching material lacks the characteristics such as interactive and solid,
It is difficult to give learner substantial efficient guidance, particularly the value such as the entity dissection and surgical operation still few money of chance high
Source is rare, the advantage of the VR that exactly hits.VR can provide the more excellent medical training not provided under classroom environment for student.
By solid modelling, positioning distance measuring, five dimension coordinates（Three dimensions+parallel universe）Etc. technology, VR is dissected and empty in simulated organ
Intend the huge advantage that surgical operation aspect hardly matches with conventional teaching.
Common VR technologies only only have the operating personnel can to carry out full experience to whole system, and surrounding
Viewing and emulating personnel can only then follow the visual angle of operating personnel, be so easily caused the personnel of viewing and emulating and have serious dizzy sense and cannot
Operating personnel are accurately instructed.And if it is desired to by the influence of virtual world it is outwardly live when be also required to by
Auxiliary equipment with high costs etc..
The content of the invention
For the problem that background technology is present, the present invention provides a kind of artificial hip joint replacing based on virtual reality technology
