In this era of interdisciplinary fusion of two seemingly unrelated research "mash-up" is likely to produce a chemical reaction, and the result is expected to be applied to the reaction of ordinary people working or living. Right now is a case -
When Virtual Reality (VR) encounters psychology, many research results collide. Some of them are expected to treat Alzheimer's disease and even help detoxification and analgesia. VR has reported that the research group of the Department of Psychology and Behavioral Sciences of the Zhejiang University and the S-Tech Studio of the Tencent Research Institute jointly published the report “VR Tide: What kind of impact VR has on people and society?â€, demonstrating this. One statement.
Alzheimer's disease, commonly known as Alzheimer's disease, is one of the common diseases of the elderly. Memory loss until severe damage or even loss is its main symptom. According to the report, a brain area known as the hippocampus in the human brain is closely related to memory ability. When in a stimulating rich and interactive environment, the number of neurons in the hippocampus will increase, and the intensity of activity will increase. Big, memory capacity will also increase.
The report's main researcher, Li Wei, a researcher at the Department of Psychology and Behavioral Science at Zhejiang University, said that VR can stimulate the hippocampus and help humans improve their memory. According to the report, VR can provide exceptionally rich stimulating content, thus enhancing the vitality of the hippocampus of the elderly, but also can improve the lives of older people monotonous content issues, moderately stimulate the brain and the elderly to exercise.
In addition, when people actively explore in the environment, they often better remember what happened. Li Wei said that in VR, the elderly can move through the environment through various control devices to solve the problem of poor seniors' exploration ability caused by physical inconvenience.
Li Wei also said that VR has a "pro-mirror", which emphasizes the user's subjective feelings and can transfer the user's attention from the real pain to the world of VR. It is also expected to become an analgesic for childbirth or burns. therapy.
Dr. Yan Chenxi of Zhejiang University’s Department of Psychology and Behavioral Sciences said that the root cause of some mental diseases is that patients cannot adapt to their environment. In this case, VR technology can tailor an easily adaptable environment for patients, help patients correct their cognition, and bring new possibilities for psychotherapy, including special phobias (such as claustrophobia and socialization). Fear, fear of flight, etc.), substance addiction, and treatment of mental illness such as autism.
Taking the treatment of children with autism as an example, she used VR to set up different children's favorite scene layouts in immersive virtual reality, to personalize treatment, maximize contact and improve the success rate of learning. In addition, it can also Provides children with real-person communication that is more complex than the real world, and has virtual, personal interaction with structured, clear, consistent behavior and feedback.
Of course, researchers including Li Lan also mentioned that there are still some deficiencies and problems in the application of VR. For example, in VR, distance perception is further compressed. Li Wei said that the perceived distance in VR is only about 70% of the perceived distance in the real world. That is, if the real world perceptual distance itself is compressed, the perceived distance in VR is only about 50% of the actual physical distance.
"This kind of VR spatial compression will get the wrong spatial perception, and may even affect the depth visual development. Especially in a series of skill trainings using VR, when the students' motion control adapts to the visual deviation in VR, they will The real world is not adaptable.†Li Wei said, how to eliminate the gap between spatial perception and real-world spatial perception in VR needs further study.
