Application of virtual reality technology in pharmacy

The applications of virtual reality technology in pharmacy are as follows:

1: Application of virtual reality in medical education.

Virtual reality (virtualreality, VR) technology, is the use of computers to create a virtual three-dimensional scenarios, providing users with visual, auditory, tactile and other sensory simulations, so that the user, as if he or she were in a real-time, unrestricted observation of the things in the virtual space, and through human-computer interaction equipment for real-time manipulation of objects within the virtual environment and design The simulation allows users to observe things in the virtual space in real time and without limitations, and to manipulate and design objects in the virtual environment in real time through human-computer interaction devices.

Currently, this technology has been widely used in the fields of entertainment, machinery manufacturing, and aerospace. However, the application of VR technology in the medical field is still in its infancy due to the strong specialization in the medical field

, the rapid updating of knowledge, and the high threshold of entry. Compared with traditional medical education and training methods, VR technology has huge advantages.

Using the VR development system to carry out three-dimensional design of medical objects, build virtual learning situations, and then assisted by text, pictures and other supplementary information, can be a high degree of refinement to present the system's preset learning content, combined with human-computer interaction equipment, the students can roam in the virtual scene constructed by the system, and even on the scene of the virtual information for the operation and design, so as to achieve a full range of display of the learning content of the target

As early as the 1980s and 1990s, medical research workers in Europe and the United States have begun research on the virtual image of the human body, the Institute of Medical Technology of the University of Hamburg, Germany, took the lead in creating a 3D virtual human body atlas and used it for the visualization of medical students teaching, but the degree of simulation is limited.

Since the 21st century, the rapid development of computer technology, multimedia technology, simulation technology and the integration of each other for the construction of the VR system provides a powerful technical support, VR technology for medical education has become within reach.

1The advantages and characteristics of VR teaching in the face of the rapid development of medical technology and people's higher requirements for the level of health care, medical positions on the level of theoretical knowledge of medical students and clinical practice put forward a higher standard. The traditional teaching method of medical teaching through the teacher's book lectures, mold operation and on-site observation, etc., inevitably exists in the theoretical knowledge is abstract and difficult to understand, practice and clinical disconnect and other problems.

The application of VR technology for medical teaching can make up for the shortcomings of traditional medical teaching, VR technology can create a readily available

laboratory and close to the eyes of the observatory, this realistic personal experience and feeling is not comparable to traditional teaching methods.

The virtual teaching platform developed with VR technology can create an immersive virtual training environment with a variety of medical images and data information, where students can directly observe human body details through a 3D mannequin, from visual, auditory, and tactile multi-sensory senses, and interact with the physical objects in the virtual environment with the help of multi-sensors, head-mounted displays (HMDs), and extra-sensory devices.

This visual, auditory, and manipulative virtual learning system allows students to be fully immersed in a three-dimensional virtual environment for independent learning, and to acquire knowledge and skills in a comprehensive way through interaction between themselves and the environment.

For example, a VR surgical system is used to simulate a surgical operation. The system allows multiple people to intervene at the same time to collaboratively***complete a surgery together or observe an operation in a ****enjoyment mode. During the operation, the computer AI can provide students with visual, auditory, and motor . Comprehensive guidance, the teacher or expert can also directly intervene to provide real-time guidance.

This teaching method will help students understand the basic medical theory, master the basic clinical skills, and play a huge role in improving the ability to analyze and solve problems. In addition, the investment in expensive experimental objects (cadavers, dummies, molds, etc.) and equipment is a huge burden on medical research institutions, VR technology is not subject to specimens, venues, time and many other factors, so that the teaching and training activities according to the needs of anytime, anywhere, while reducing the cost of investment in teaching and learning to obtain good teaching results.

Not only can significantly reduce the economic burden of medical research institutions, but also can effectively shorten the training of researchers to practice time.

2VR technology in the field of medical teaching, 2.1 simulation teaching to strengthen the teaching effect.

Medicine requires students to memorize a lot of knowledge points, students want to remember the knowledge points in the book to a large extent rely on memorization and teacher explanations, this way requires students to put in a lot of effort. With the VR teaching system, the teacher can select a simulated teaching situation for the students for specific knowledge points, and the students can learn the set knowledge points through the 3D video screen dynamic demonstration and human-computer interactive interface operation.

For example, to learn the structure of the human skeleton, students use the virtual system of human-computer interaction interface, with the guidance and explanation of the system robot, students can directly on the 3D digital human anatomy, immersive observation of specific parts of the structure of the skeleton, this first-hand experience of the feeling of the students of the knowledge of what they have seen and heard can be unforgettable, and is conducive to improving the learning effect.

2.2.2 Autonomous Learning to Improve Creative Ability Through the virtual scene set intelligent virtual teaching, so that students learn from passive acceptance into active knowledge. In the virtual environment students can design their own learning situations, develop experimental programs, for example, students can observe the human body structure model under different parameter conditions through the human-computer interaction system.

Model of a single organ, or internal "roaming", local anatomy and other explorations, this way of learning can greatly expand the teaching space and teaching content, stimulate students' interest in learning and improve the ability to innovate, so that the students really from "to learn" to "to learn".

2.3 Simulation of practical training to objectively evaluate the learning effect.

Traditional medical education on student learning is examined mainly through the theoretical examination, but simply through the examination scores can not be comprehensive examination of students' knowledge mastery and practical ability. Through VR technology, the teacher enters the basic information of the digital human body, diagnostic and treatment parameters and drug effects and other data in advance, and then lets the students independently analyze the condition on the virtual human body model and implement diagnosis and treatment.

The system automatically collects students' real-time operation data and makes diagnosis and treatment evaluations, thus realizing the visual management of the whole teaching process and real-time assessment of students' mastery of knowledge,

which will help teachers to better deal with the knowledge blind spots and weaknesses that exist in the process of teaching and enhance the effectiveness of the teaching.?

2.4 Medical simulation and diagnosis to improve practical ability.

The combination of traditional internship observation methods and virtual diagnostic items will be conducive to the students' acquisition of more practical experience and mastery of basic clinical skills during internship. For senior students and standardized training doctors, on-site observation is the main training method for clinical practice. VR simulation diagnosis can make up for these shortcomings.

Medical trainees using the VR system can carry out bold diagnostic experiments on the virtual human body to test the response of different treatment options on the human body, thus obtaining a large number of virtual diagnostic data, comparing these data with the patient's actual physical indicators to analyze the gap between theory and practice, which will help students to gain clinical experience, and deepen their understanding of the basic theoretical knowledge. In the clinic, the virtual diagnosis and treatment data can also be used as the auxiliary judgment index of various complex diseases.

2.5 Virtual molecular design to promote pharmaceutical research and development.

Molecular biology, pharmacy and other basic disciplines in the development of medicine plays an irreplaceable role, but most of these disciplines are at the molecular level of the object of study, the naked eye can not see, can not touch, the study is very abstract, and often give a person a kind of indefinable and indefinable feeling. vr technology can be all kinds of molecules microstructure macroscopic demonstration, so that drug researchers realistically and clearly see all kinds of molecular structure 3D model. The VR technology can display the microstructure of various molecules in a macroscopic way, enabling drug researchers to see various 3D models of molecular structure realistically and clearly.

Through human-computer interaction equipment, molecular models can be modified and designed, which will bring a lot of convenience to drug research. Macroscopic display of compound microstructure can deepen researchers' understanding of compound structure and help find the best synthesis path; simulation of the combination of various biomolecules and drug small molecules to find out the best binding site between drug molecules and biomolecules, which is conducive to the exploration of pharmacological properties.

Observing the whole process of chemical reactions between active molecules under specific conditions is conducive to exploring the biological properties of active molecules. These conveniences will help drug developers to design and synthesize drugs in a more targeted manner, shorten the drug development cycle, and reduce research and development costs.
