Compared with the past, the exhibits in this exhibition cover a wider range of application fields, including education, film and television, industry, sports, medical treatment, culture and tourism and other application scenarios; The on-site exhibition experience is also stronger. Cultural and entertainment experience projects such as game confrontation and VR film bring interaction and sensory feast to the experimenters through multiple senses such as touch, vision and hearing. Continuous optimization of hardware performance In the VR / AR glasses / helmet Market, 4K HD display has become the standard configuration of near eye display. Camera tracking, inside out, outside in and other types of tracking systems have attracted the attention of different manufacturers. Screen display and camera dual display system have become the application direction of the industry. At the exhibition site, HP brought the HP revert G2 VR headset, equipped with 4K HD display, built-in 4 cameras for tracking and positioning, as well as facial cameras and eye tracking system, which can capture users' biometric data in real time, making the device more collaborative. The device is also equipped with heart rate measurement to help users monitor their physical condition in real time during use. When the reporter arrived at the venue, there was a long queue in the Nolo sonic all-in-one machine experience area opened by Nolo. An uncle who had just experienced sonic music games happily watched other players play games and said to the reporter of China Electronics News: "the experience is very good. There is no dizziness and discomfort. He wants to play again." the announcer of Nolo booth introduced to the reporter of China Electronics News that the sonic all-in-one machine has achieved 4K resolution and 72HZ refresh rate, Equipped with Qualcomm snapdragon 845 processor, the viewing angle range is 101 degrees, and the insid out positioning system is applied. From the perspective of parameters, the hardware performance of the equipment is very close to the industry-leading level. It is worth mentioning that Nolo sonic is equipped with a broadband vibration motor, which supports 0 ~ 1000Hz frequency point vibration response, and can simulate the tactile output of various scenes, which makes users have a stronger sense of interaction. The xviio slimedge ar glass-e34rb brought by Shanghai interpretation Sensing Technology Co., Ltd. has immersive 6DOF interaction capability and is equipped with free-form surface optical scheme, which can realize the virtual real integration of 3D space. Users can interact through posture, gesture, voice and other methods. The reporter experienced the use of the product at the scene. After wearing the product, a civil aircraft appeared in the venue. There is a white bright spot in the field of vision, which is the control system provided by the glasses for the user. By turning the head, the user can interact with the scene in the field of vision by moving the position of the white bright spot in the field of vision. The commentator of Shanghai interpretation booth introduced to the reporter of China Electronics News that the glasses can be applied to the explanation of large-scale equipment. The experimenter can control the light spot in the glasses to interact with the scene in the field of vision, so as to watch the preset introduction of different positions in the AR image. Using this way to learn civil aviation knowledge is more intuitive and impressive. VR / AR education is more widely used Compared with industries such as industry, culture and tourism, VR / AR is more widely used in the education industry, more closely combined with the industry and covers a wider range of age levels. From the exhibition results of this year's exhibition, VR / Ar + education has been able to cover all learning stages from preschool education to 12-year education and vocational skill training in primary school, junior middle school and senior high school. "I'm watching Tyrannosaurus Rex in dinosaur paradise!" on the booth of Hengxin Oriental VR future classroom, a child who was experiencing shouted excitedly. The commentator of Hengxin Oriental introduced to the reporter of China electronic news that what the child is experiencing is the content of VR course designed for preschool children to enter the ancient world, which is one of the nine categories of VR future classroom courses exhibited by Hengxin Oriental this time. The duration of VR interactive experience designed for young children is 10 ~ 15 minutes each time. Teachers can monitor the use progress of multiple devices through tablet terminals. For school education from primary school to high school, Jiangxi Kejun exhibited kmax desktop all-in-one machine. The exhibition site is equipped with 30 kmax all-in-one machines. The teacher explains the composition of plant cells on site. With the teacher's explanation, students can wear glasses and hold the special controller of the all-in-one machine to drag and drop the three-dimensional graphics of plant cells on the screen, so as to observe the composition of plant cells from multiple angles. In this way, AR course can be perfectly embedded into the school curriculum system and become an auxiliary tool to help students understand classroom knowledge and deepen classroom cognition. According to the commentator of Jiangxi Kejun, kmax desktop all-in-one machine has reached cooperation with more than 100 schools. For the scene of vocational education, the exhibition showed a very rich range of applications. Among them, in order to solve the problem of high equipment trial and error cost encountered by vocational college students, Beijing Yizhi times exhibited 5g cloud XR intelligent platform digital twin system. Students can experience real operation scenes by wearing head display, which reduces operation cost and use risk while mastering skills. Guangdong Academy of simulated medicine has launched a virtual acupuncture VR teaching system, which uses force feedback and virtual reality (VR) technology, combined with 3D meridian acupoint anatomy virtual human body, to carry out meridian acupoint anatomy learning and acupuncture meridian acupoint manipulation training, so as to strengthen users' understanding, memory and mastery of acupuncture meridian acupoints. For adult vocational skills training projects such as driving training, welding training, machine tool electrical fault diagnosis and maintenance, large engineering vehicle driving skills training, China Telecom Jiangxi branch, Jiangxi Kejun, Jiangxi Huatian virtual simulation demonstration base, etc. exhibited their own solutions respectively. For special scenes such as patients with autism and cognitive impairment, century Huatong exhibited autism VR evaluation and rehabilitation training system and cognitive impairment VR evaluation and rehabilitation training system. Patients wear VR display equipment and interact with the preset scenes in the equipment to achieve the effect of rehabilitation training. The system can also record the training data in real time, which is convenient to check the training effect. "VR / Ar + entertainment" closely follows the market hot spots As a new form of content presentation, the application of VR / AR in the field of entertainment is not limited to VR reproduction of videos and games, but began to develop entertainment content based on the technical characteristics of VR / AR in combination with the hot market trend.
