What are the functions and effects of VR technology?

VR technology has great potential and will change many fields in the future. The following carefully recommended the role and efficacy of VR technology for you, hoping to help you.

Functions and Efficacy of Virtual Reality Technology

1, to help paralyzed patients recover their physical functions.

Duke University conducted a one-year study and found that VR technology has great benefits in treating paralyzed patients. The researchers asked patients to wear virtual reality helmets and walk across the playground like football players. Researchers have found that this can help patients recover some brain functions related to leg movements. Among the 8 patients tested, each patient recovered some control ability, and 4 of them changed from complete paraplegia to partial paraplegia.

2. Treatment of post-traumatic stress disorder

Traditionally, doctors treat nearly 8 million adult PTSD patients with exposure therapy every year. Exposure therapy encourages patients to tell their own mental trauma, visualize their traumatic process in imagination, and explain to doctors what happened under the tense situation at that time. The new therapy basically adopts the same method, while using virtual reality helmet to create a virtual world with customized elements (for example, helicopters, machine guns and missiles can be customized in the experience of veterans). Then, ask the patient to tell what happened at that time.

3. Training medical students

Virtual reality technology provides a safe and controllable environment for medical and dental students to practice surgical procedures and prepare for emergencies. In such an environment, medical students can make mistakes, but it will not have any impact on actual patients. Students can learn in the process of "hands-on" and interact with virtual patients, which can better cultivate medical skills.

Step 4 relieve pain

Through virtual reality technology, doctors use "distraction therapy" to help patients alleviate the pain when receiving physical therapy. A study on the burned patients in the war of 20 1 1 shows that the virtual reality game Snow World-in this game, users can throw snowballs at penguins and listen to paul simon's songs at the same time.

Step 5 treat anxiety disorder

More than 40 million adults in the United States suffer from anxiety. Virtual reality game "Deep"-"Digital Diaphragm Movement"-can help anxiety patients cope with fear and anxiety. In the game, users will use belts to monitor their breathing. This game brings users into the natural environment, guides them to practice abdominal deep breathing and calms down after about five minutes.

6. Help people with autism develop social skills.

Professors at the University of Texas in Dallas have created a therapy that uses virtual reality technology to help autistic children and adolescents develop social skills. This treatment puts children and adolescents with autism in a social scene, such as an interview or a blind date, so that they can learn how to understand social cues and respond accordingly. By monitoring the patient's brain waves during the treatment, the professors found that the patient's social skills were improved.

7. Promote business development

Video chat is a kind of virtual reality. Now, enterprises begin to adopt virtual reality technology in many aspects: reducing costs, reducing business travel, conducting interviews, predicting trends and holding meetings, and so on. In the past, business managers often went out to attend meetings or talks and often had to interview candidates face to face. Now, enterprises can use virtual meeting rooms to accomplish these tasks. Those enterprises that produce dangerous products have begun to use virtual reality technology to test the safety and performance of products to avoid harm to the health of employees.

8. Promote architectural design

Virtual reality technology will benefit the main participants in the construction industry, such as architects and designers. Virtual reality technology enables users to live in three-dimensional space. Computer-generated images will replace hand-drawing, thus shortening the time for designing and modifying drawings, effectively reducing costs and improving safety. Simulating the real world can not only make it easier for designers to create buildings and spaces, but also allow designers to conduct environmental tests before actually creating them. For example, they can really see how quickly people can leave the building in an emergency.

9. Test car safety and promote sales.

Virtual reality technology enables automobile engineers to test the safety of automobiles before actual manufacturing. In addition, large automobile companies, such as Ford, Volvo and Hyundai, can use virtual reality technology to help sales and let potential customers use virtual reality helmets to test drive their cars.

Plan your next trip.

Soon, you can try your tourist destination through virtual reality technology. Before booking a plane ticket to a destination, passengers can observe the destination in virtual reality, including hotels and cityscapes in the city.

Why are VR videos curved?

Our VR device uses two circular convex lenses, so that when our eyes look at the display screen behind the lenses, there will be different degrees of "pincushion distortion" at the video edge.

At this time, in order to prevent distortion from reducing the visual experience, we will make a "barrel distortion" on the original video in advance, so that once the two are offset, the video we see is normal.

The concept of virtual reality technology

VR(VirtualReality), namely virtual reality (or spiritual technology), is a computer system that can create and experience virtual worlds.

In fact, the connotation of virtual reality is a technology that comprehensively uses computer graphics system and various interface devices such as reality and control to provide immersive feeling in a computer-generated interactive three-dimensional environment. Similar to 3D technology, friends who have seen 3D movies should have more feelings.

20xx is called the first year of VR equipment, and many manufacturers begin to develop VR equipment, which will make human communication adopt a new way and enter a new field.

At present, many manufacturers have begun to introduce VR devices, such as HTCVive, AMDSulonQ, Sony PSVR, etc. At present, these devices are mainly VR glasses or head theft devices, and you can experience some VR videos and games. , bring 3D scene experience and give people an immersive feeling, and bring a more extreme user experience.

Of course, VR devices not only have an experience in entertainment, but also bring new application scenarios in future movies, paintings, virtual reality games, learning, medical care and so on. Because more real and immersive experience will inevitably become the mainstream in the future.
