Description
Technical field
The present invention relates to real-time graphics systems and virtual reality interaction technique, belong to virtual reality interaction technique neck
Domain.
Background technique
Human-computer interaction, human-computer interaction (English: Human-Computer Interaction or Human-Machine
Interaction, abbreviation HCI or HMI), it is the knowledge of the interactive relation between a research system and user.System can be
Various machines are also possible to the system and software of computerization.Human-computer interaction interface typically refers to the visible portion of user
Point.User is exchanged by human-computer interaction interface with system, and is operated.The broadcasting button of small Source Music, greatly on aircraft
Instrument board or power plant control room.The design of human-computer interaction interface will be comprising user to understanding (the i.e. intelligence mould of system
Type), that is the availability or user friendly for system.
With the development of computer technology, operational order is also more and more, and function is also increasingly stronger.With pattern-recognition,
Such as speech recognition, the development of Chinese Character Recognition input equipment, operator and computer are being similar to natural language or restricted
Interaction is carried out in this level-one of natural language to be possibly realized.It goes to carry out in addition, carrying out human-computer interaction by figure and also attract people
Research.These human-computer interactions can be described as intelligentized human-computer interaction.
Virtual reality technology is that an important directions of emulation technology are emulation technology and computer graphics man-machine interface
The set of the multiple technologies such as technology multimedia technology sensing technology network technology is a challenging interleaving techniques forward position
Subject and research field.Virtual reality technology (VR) mainly includes simulated environment, perception, the natural side such as technical ability and sensing equipment
Face.Simulated environment be generated by computer, dynamic 3 D stereo photorealism in real time.Perception refers to that ideal VR should have
There is perception possessed by all people.In addition to computer graphics techniques visual perception generated, there are also the sense of hearing, tactile, power to feel, fortune
It is dynamic to wait perception, or even further include smell and sense of taste etc., also referred to as more perception.Natural technical ability refers to the head rotation of people, eyes, hand
Gesture or other human body behavior acts are handled the data adaptable with the movement of participant, and the input to user by computer
Real-time response is made, and feedback arrives the face of user respectively.Sensing equipment refers to three-dimension interaction equipment.
Computer screen is planar, and why we can enjoy just like the 3-D image as material object, be because
Display on the computer screen when color gray scale difference and so that human eye is generated visual illusion, and by two-dimensional computer screen
Curtain is perceived as 3-D image.Related knowledge based on color science, the generally aobvious high luminance color in the protrusion part at three-dimension object edge, and
It is sunk partially due to being blocked and aobvious dead color by light.This understanding be widely used in webpage or other application to by
The drafting of button, 3d lines.Such as the 3d text to be drawn, i.e., in home position exhibit high brilliance color, and in lower-left or upper right
Its profile is sketched the contours of with low-light level color in equal positions, will visually generate the effect of 3d text in this way.It, can when specific implementation
The 2d text of two different colours is drawn respectively in different positions with duplicate font, as long as making the coordinate of two texts
Properly, the 3d text of different-effect just can be visually produced completely.
The application of many virtual reality interaction techniques in the prior art, such application must be in conjunction with 3-D technologies, still
Currently, 3-D technology to show power limited, in practical applications without systematization, form exhibition of the scattered X-Y scheme to piece together
Existing, general with merging for virtual reality interaction technique, this technology is the core of current VR equipment, therefore before having preferable development
Scape.
