Interpretation of technical characteristics of VR virtual reality technology

Virtual reality is a synthesis of many technologies, including real-time three-dimensional computer graphics technology, wide-angle (wide-field) stereoscopic display technology, observer's head, eye and hand tracking technology, tactile/force feedback, stereoscopic, network transmission, voice input and output technology and so on. So what are the characteristics of these technologies? The following extraordinary education teachers will interpret the technical characteristics of VR virtual reality technology.

VR art is a new independent art category with the advent of the "virtual reality era". In the article "Virtual Reality Art: Metaphysical Ultimate Re-creation", there is the following definition about VR art: "An art form with artificial intelligence technologies such as virtual reality (VR) and augmented reality (AR) as media means, which we call virtual reality art for short. The main features of this art form are hypertext and interactivity. "

"As a comprehensive embodiment of the frontier of modern science and technology, VR art is a new artistic language form for visual operation and interaction of complex data through man-machine interface. What attracts artists is the close integration of artistic thinking and scientific and technological tools, and the brand-new cognitive experience generated by their deep penetration. Compared with the new media art under the traditional window operation, interactivity and extended man-machine dialogue are the key points for VR art to present its unique advantages. Generally speaking, VR art is an interactive art form based on the new man-machine dialogue. Its greatest advantage lies in constructing a dialogue between the work and the participants, and revealing the process of meaning generation through dialogue.

Through the application of VR, AR and other technologies, artists can control the form of works with more natural human-computer interaction, create more immersive artistic environment and dreams that cannot be realized in reality, and give new meaning to the creative process. For example, the interactive device system with VR nature can set the process of the audience crossing the multi-sensory interactive channel and crossing the device. Artists can promote the communication and feedback between participants and works with the smooth cooperation of software and hardware, and create a good sense of participation and operability; You can also capture the action through the video interface, store the behavior fragments of visitors, and show the enhanced effect and the reshaped image simultaneously on the basis of maintaining the awareness of participants; By combining the digital world with the real world through augmented reality, mixed reality and other forms, the audience can control the projected characters through their own actions, such as data gloves, which can provide force feedback. Movable scenes and 360-degree rotating sphere space not only enhance the immersion of the work, but also allow the audience to enter the work, manipulate it, observe its process, and even give the audience the opportunity to participate in re-creation.
