Keywords: Virtual reality technology; Wisdom library;

One, foreword

Virtual reality technology (also called VR technology) is a three-dimensional virtual world built by using computer software and hardware technology, speech recognition and synthesis technology, man-machine interface technology and other intelligent technologies. It uses a variety of sensing devices to simulate visual, auditory, tactile and other sensory experiences, and then feedback according to the user's actions to help the user interact with the virtual world, and finally let the user have an immersive experience. With its unique autonomy, interaction and immersion for users, virtual reality technology has attracted extensive attention from researchers at home and abroad. More and more fields begin to pay attention to the introduction of virtual reality technology, and library is no exception. The application of virtual reality technology in library brings personalized and intelligent service experience to users, and it is more and more loved and valued by users.

At present, in the face of users' increasingly diversified demand for information services, the resources and services that traditional libraries can provide are extremely limited. At the same time, the physical space for storing literature and information resources in most libraries is approaching saturation. These difficulties need to be solved urgently. In recent years, many libraries in China, such as the National Library of China and the Library of Nanjing University, have introduced virtual reality technology and combined it with smart library in an effort to break through the traditional library

Limited, for users to provide personalized intelligence services, greatly meet the information needs of users. The application of virtual reality technology in smart library widens the idea and way of library service, improves the way and idea of library service, extends the function of library service, enhances the service experience of users, and encourages the library to continuously move towards service transformation and innovative development.

Second, the connotation and characteristics of smart library

Smart library is a combination of intelligent technology and digital library, which is a kind of intelligent innovation. Smart library can realize intelligent service and management of the library through a series of new technologies such as cloud computing, Internet of things, big data and so on, so that users can sense and use the intelligent service of the library in real time without the limitation of space. For example, some university libraries in the United States use virtual simulation technology to allow users to access the library remotely and roam the library in real time by reading, browsing, listening and other ways. Virtual simulation technology helps users to use the resources of the library, enjoy the service of the library, bring users a good service experience, greatly improve the satisfaction of users.

Wisdom library has three characteristics: first, knowledge sharing. Smart library makes use of intelligent technology to connect users with literature information, which can fully realize the all-dimensional, three-dimensional and time-transcend knowledge sharing, and at the same time provide readers with real-time, online and all-dimensional knowledge services. Second, service efficiency. Compared with the services carried out by traditional libraries, smart libraries can use intelligent positioning or tracking technologies to help readers find the required literature and resources accurately and quickly, provide readers with efficient and intelligent services, and promote readers to make more effective use of the required resources. Third, the convenience of use. With the development of information technology, smart library will provide users with more convenient information services, including information resource updating without limitation of time and space, and more and more optimized literature information retrieval services.

Iii. Featured experience of smart library supported by virtual reality technology

Virtual reality technology can provide users of smart library with immersive space experience, mixed reality environment experience, participatory learning experience and immersive reading experience due to its multi-sensory, user immersion, interaction and conceivability.

1. Immersive space experience

Immersive VR allows readers to stay in a separate, fully enclosed space and experiment and operate in the space with A VR device. In the virtual environment, Wisdom Library provides readers with an immersive virtual reality experience, which enables the interaction between readers and the experimental subjects, so that readers can fully experience the convenience and comfort brought by the immersive virtual reality technology. The immersive reading space experience provided by smart library is becoming a new mainstream reading way, leading readers to enter the trend of new reading. For example, in the VR experience area of the National Library of China, readers can use VR wearable devices to "walk" in the library, feel the architectural style of the library, get familiar with the functional layout of the library, and "watch" lectures, exhibitions, lectures and other activities held by the library in real time, maximizing the immersion of users. These are the traditional audio, video and other multimedia technology can not achieve.

2. Mixed reality environments

Mixed Reality VR is to present the objects that are difficult for readers to access through the integration of 3D images and computers, so as to produce virtual objects for readers to feel up close. The experience and immersion of Mixed Reality VR are more real, which can further stimulate readers' imagination. Mixed reality virtual technology can superposition real things into the virtual world, through the sense of vision, hearing, touch recipients completely can not believe that they are in a virtual world. In 2014, North Carolina State University established a VR technology application lab in the library. Every user can experience the external environment through VR devices in this lab, and also carry out experiments in this virtual space, providing users with a convenient and fast mixed reality virtual environment experience. Such as traffic management professional students can clearly observed in the space of city traffic condition and road transport distribution situation, and don't have to go to the road of the city, the mix of reality of the virtual environment experience let users never leave home can be immersed in the virtual reality environment, anytime, anywhere to get to know and feel your required information.

3. Participatory learning experiences

The smart library supported by virtual reality technology allows users to observe and contact things and experiments closely in the virtual space. Users can create and research experiments in the virtual THREE-DIMENSIONAL world according to their own ideas, which greatly enhances the learning experience of users and improves their independent learning ability. For example, by wearing VR devices, users can clearly grasp the operating state of the aircraft during the flight, and can also sense or experience the faults that may occur in each part of the aircraft, and finally give effective experimental data. The virtual reality technology can also simulate the natural environment such as wind speed and airflow during the flight of the aircraft, which has stimulated the research enthusiasm and learning interest of users.

The intelligent library supported by virtual reality technology shows readers not books and TWO-DIMENSIONAL code pictures, but three-dimensional experimental desktop, which is a new way of learning. Virtual reality technology can clearly show things in three-dimensional space, so that readers can understand what they need more intuitively. In this virtual space, readers can witness the experiment or reproduce the experiment themselves. These virtual reality environments make readers feel the fun of learning and inspire them to carry out more comprehensive research and think more deeply.

An immersive reading experience

The intelligent library supported by virtual reality technology enables readers to put themselves into the virtual environment, make them feel the intelligence of the library, and make them pay more attention to the resources and services of the library, which are more intelligent and personalized than the services and experiences provided by traditional libraries. Smart library can make use of virtual reality technology to constantly make corresponding changes according to readers' reading environment. When reading, readers can have a virtual reality experience sense of "fragrance of flowers in spring and cold wind in winter", and can also inspire readers to generate more creativity and ideas.

Iv. Advantages of intelligent library service supported by virtual reality technology

The application effect of virtual reality technology in smart library depends on the breadth and depth of virtual reality technology used by the library. To be specific, the service advantages of virtual reality technology for smart library include the following aspects.

1. Convenient retrieval of information resources

The intelligent library supported by virtual reality technology can classify and index the literature information resources better, so that users can query and retrieve the required information more conveniently and in real time. At the same time, the virtual reality technology to the literature information resources for 3 d three-dimensional display, when readers enter search keywords retrieval system can realize the intelligent retrieval, and automatically to the relevant literature knowledge of three-dimensional appear in front of readers, make readers have a more intuitive knowledge of literature information resources, bringing great readers retrieval and utilization of literature information resources.

2. Virtualization of collection resources

Smart library builds virtual database through virtual reality technology, which can realize the virtualization of collection resources, and make graphic and graphic drawings of collection resources to build the virtualization model of various physical resources. The virtualization of collection resources saves the physical space of library to a large extent and reduces the pressure and loss of the physical space of library. Through digital storage and network transmission, smart library optimizes the allocation of library collection resources and can better meet the information needs of readers.

3. Maximize resource utilization

Supported by virtual reality technology, smart library breaks the constraints of traditional library in time and space, and can provide a variety of information resource services in a timely, effective and all-round way. At the same time, the resource utilization rate of smart library is also greatly improved. Through virtual reality technology, the literature and information resources of smart library are fully mined and integrated, and recommended to readers for timely use, which effectively improves the utilization rate of readers' literature resources and effectively guarantees the maximum utilization of resources.

4. Intelligentized reader service

The intelligent library supported by virtual reality technology can automatically identify readers' identity information, understand readers' reading interests and preferences, and automatically realize accurate matching of information services, intelligent recommendation and other functions according to readers' needs. Intelligent reader service can effectively improve readers' reading experience, make readers more convenient and faster to find the resources they need, save the time for readers to search and retrieve information, and practice the "reader-centered" service concept.

5. Personalize user experience

Traditional library provide personalized service for readers, general is to understand the readers' reading interest and habit, and then screening and analysis of library collection resources, put each platform to integrate resources and pushed to the reader, this way of service means a single, low utilization rate of resources, leading to poor user experience of service, user's satisfaction is not high. The application of virtual reality technology in smart library provides a new method and way for the information service of readers, and enhances the user experience. For example, in the smart library, readers can set up a virtual personal library, choose different interfaces and functions according to their preferences and styles, and put the books they are interested in on the personal shelf of the virtual library, which is easy to collect and read at any time. The application of virtual reality technology can provide more personalized services for users of intelligent library and continuously improve the effect of user experience.

6. Diversification of information exchange

Virtual reality technology provides readers with a broader space for learning and communication, which is conducive to readers' learning, communication and innovation. VR devices can establish diversified ways of information exchange, which can bring researchers from different fields and disciplines with common interests together to carry out learning exchanges or scientific research together. This diversified way of information exchange has broken the time and space limit of traditional library, greatly improved the learning efficiency and communication willingness of readers, and also increased the speed of knowledge innovation and dissemination.

In addition, the application of virtual reality technology in smart library can also reduce the information gap between users. In the traditional environment, many users are not good at using library information resources, which leads to a certain information gap between users. In the era of smart library, virtual reality technology can enable users to better understand the contents of library service information, so as to narrow the information differences between different regions and different groups, and effectively alleviate the information gap between users.

7. Facilitation of user training

As an important part of library services, the training for readers to enter the library can help readers to quickly and accurately understand the layout and functions of the library as well as the resources and services provided by the library. In the traditional environment, library entrance training is usually carried out offline in the form of lectures and lectures. The disadvantages of this method lie in that it requires the concentrated participation of readers, the scale of training is limited by the site, and the effect of training is dull and boring. Wisdom library readers in the library training conducted by virtual reality technology, and is able to simulate reduction and the layout of the library service, user roaming in the virtual library, real-time experience of literature reading, information retrieval, reference services, virtualization, such not only solved the training can't expansion caused by the reason such as the space problem, In addition, it greatly saves the human and material resources consumed when the library carries out the regular reader training.

Five, the conclusion

The application of virtual reality technology in smart library has changed the service mode of traditional library, which makes the service mode of library achieve innovative breakthrough. However, due to the limitations of funding, personnel and other factors, many smart libraries provide insufficient VR facilities and equipment, which affects the reading experience of users.

In the future, the application of virtual reality technology in smart library will be further mature and perfect. Smart library should also firmly seize the opportunity brought by the development of virtual reality technology, actively make breakthroughs in information retrieval, book lending, reference, intelligent service and reading promotion, and constantly reform and innovate.
