Edwin adjusted his headphones and grabbed the game controller with both hands.
He swallowed hard.
There is good reason for this person to feel nervous.
He is about to enter a virtual environment.
Let his heart beat more than anything.
A coffee shop full of people.
Edwin, determined to overcome his continued fear of others wanting to hurt him, took part in a new study of VR therapy.
Research in public places.
In this show, Edwin can visit the shops or board the crowded bus.
Virtual strangers, like real people, can be intimidating.
Edwin, who is diagnosed with paranoia, often finds that simple errands like grocery shopping can be exhausting.
But there are extra benefits in the face of simulated people.

She can customize the number of avatars and set their level of friendliness in each scene.
In this way, Edwin can move forward at his own pace.
At a meeting, Pot-
Kolder coached Edwin and challenged his skeptical assumptions.
If he sees an angry man
Looking at Avatar, she asked, \"What are the other reasons for looking crazy other than trying to hurt you ? \" Edwin suggested that the person may be tired or have a personal problem.
Edwin said it was easier for the public to travel after three months of virtual reality treatment, and he asked not to use his last name.
\"I feel more free and relaxed.
He even performed a poem for 500 people in a talent show, and he used to \"dare not \".
Researchers have been developing virtual reality systems since the 1990 s to help people overcome specific fears.
Virtual reality therapy has expanded to address more complex anxiety disorders such as social anxiety and post-
For people like Edwin, traumatic stress, and even anxiety associated with paranoid mental division.
\"The key factor in effective treatment of anxiety disorder is . . . . . . You need to face your fears, \"said st éphane Bouchard, a clinical network psychologist at the University of Quebec, Canada.
He refers to the so-called exposure therapy.
With the emotional support of the therapist, exposure therapy helps to make patients less sensitive to any fear.
Patients usually face their fears in real life, or, if their fears are a traumatic memory, they will experience the event repeatedly in their imagination.
But it may be easier to face fear in a virtual environment. A flight-
Phobias can take off and land multiple times in a virtual reality session without the cost and hassle of an actual flight.
Veterans and post
Traumatic stress that cannot be memorized in detail for traumatic memory can reproduce a close agent in virtual reality for a more effective therapeutic experience.
The same is true of those who suppress painful memories.
Until recently, the price and complexity of VR devices have limited VR treatment in some research laboratories and clinics that can run tens of thousands of dollars.
Now with the computer.
Headphones like Oculus Rift cost only a few hundred dollars, as well as headphones like Samsung Gear VR, which turn smartphones into virtual reality monitors for about $100.
Cheaper, more users
The friendly system will provide virtual reality treatment for more patients, and researchers are testing the scope of virtual reality treatment ability to treat a wider range of diseases, or in some cases, completely replace the therapist.
The power of virtual reality therapy comes from the fact that even in environments where they consciously know they are not real, people automatically react to fear cues.
This is because the emotional command center or the edge system of the brain).
Barbara rosbaum said that as a result, patients facing fear in virtual reality showed increased levels of stress hormone cortex, increased heart rate, increased skin conductivity, clinical psychologist at Emory University in Atlanta
These are obvious ().
As early as the 1990 s, when Rothbaum and his colleagues began studying VR for psychological disorders, the researchers were not sure whether computer simulations would cause these reactions.
But their VRprogram, height-
Phobias are on the bridge, on the balcony, on the glass elevator and work almost too well.
Rothbaum reviewed the first patient test.
\"We\'re excited and she\'s anxious.
We just let her in and she vomited.
\"It turns out that patients are prone to motion sickness --().
\"We think this will be the end of the study.
But the team at rosbaum is moving forward.
The group learned to rest patients after about 40 minutes in virtual reality, turn down the thermostat and warn of nausea --
Patients who are prone to illness do not move their heads.
In the first study reported in 1995, 10 participants, after 7 VR treatments per week, compared to 7 patients who did not receive treatment.
Twenty years later, research has shown that virtual reality therapy for specific phobias can alleviate people\'s fear of reality. life exposure.
Recently, researchers designed and tested VR systems to help those with more subtle and diverse triggers of fear, such as social anxiety or obsessive-compulsive disorder
Obsessive-compulsive disorder.
For social anxiety, Bochard and colleagues tested a virtual reality system that allows patients to work in stressful social situations, such as interviewing or refusing to buy things from persistent shop assistants.
The researchers treated 17 people with social anxiety with virtual reality, while the other 22 were treated with typical exposure, including exercises such as talking to strangers in public.
The third group assigned to the waiting list was not treated.
Before and after 14 weekly treatments, participants reported their fear and avoidance of social situations, from 0 to 144, with higher scores and more anxiety.
The starting score averaged between 75 and 85.
The average number of participants receiving VR treatment dropped by 33 points, while real-
The average number of life exposure participants decreased by 19. The no-
The situation in the treatment group is roughly the same.
These results from the April 2017 interim report indicate this.

Their fears tend to be more complicated than simulating normal high stress disordersrise or spider.
A system provides a broad menu of fear cues for patients with post-traumatic syndrome, created by VR therapy developer Albert \"Skip\" Rizzo and colleagues at the University of Southern California, Los Angeles, to help with post-traumatic
Mental trauma after serving in Iraq and Afghanistan.
In order to re-warm the traumatic memory in this virtual reality system, the patient first chose settings such as a road checkpoint or a hospital.
When the patient speaks the memory aloud, the therapist customizes the scene.
\"If the patient says, \'I drive along a road,\' the therapist will set it up,\" Rizzo said . \".
If the memory occurs around noon, the therapist sets the virtual clock accordingly.
If the patient recalls the rumble of a Hummer, \".
Turn up the sound of the vehicle.
\"Rizzo\'s team tested the early version of the system by randomly assigning 162 military personnel to the waiting list, using 10 treatments or 10 traditional treatments from the Virtual Iraq/Afghanistan system.
For traditional treatments, therapists guide patients through imaginary traumatic memory and help them put themselves in their daily life because of their trauma, such as crowded public places, they feel scared.
The researchers reported on November 2016 that after the study, both treatment groups compared with the treatment group on the waiting list.
\"The real question is, if VR is as good as traditional therapy, what treatments should we do for patients, and why,\" says Greg Regel \", clinical psychologist at the University of Washington and the VA Puget Sound Health Care System in Seattle.
Reger and his colleagues identified some factors by analyzing a group of military personnel in the 2016 study --
For example, if you are younger, don\'t take anti-depression drugs.
This seems to suggest that people who use virtual reality will live better.
It makes sense that young people respond more positively to technology.
But researchers don\'t know why drug use is relevant.
Further investigations such as Reger, June interim report.
For Daniel Freeman, a clinical psychologist at Oxford University, \"The beauty of virtual reality\" is that it goes beyond the experience of rendering reality.
\"You can do something you can\'t do in real life.
He said: \"For example, by talking to guide a patient with social anxiety, it is often necessary to shift the person\'s attention from himself to their environment.
In virtual reality, a therapist can guide a patient to focus on specific aspects of the virtual world and help him or her forget about himselfconsciousness.
Gerard jounyun Kim, a computer scientist at Seoul\'s Korean university, and his colleagues are testing a mix of real and fantasy elements to help people with panic disorder.
In the new VR program for researchers, users have access to potential panic
Induced situations such as parades or crowded elevators.
In case of panic, the user can click the escape button and be transported to the quiet beach.
In that safe sanctuary, the patient was instructed to breathe calmly, while they were holding a thumping device in their hands and saw a virtual heart that would beat with its own heart in time.
On 2017, at the ACM virtual reality software and technology seminar in Gothenburg, Sweden, the system was too small to accurately show the system\'s help to patients with panic disorder.
Kim and his colleagues are now conducting a more comprehensive analysis of dozens of patients.
While Kim\'s team is creating a virtual version of the patient\'s heart, a Canadian team is rendering the virtual body for the sound in the mind of a mentally split patient.
Alexander Duma, a psychiatrist at the University of Montreal, said many people taking anti-psychiatric drugs to treat mental division continued to hear voices.
Traditionally, therapists advise patients to ignore these residual illusions, but recent studies suggest that adding sound to a conversation might actually help reduce the patient\'s sense of helplessness.
So the team at dumais built a virtual reality system in which the patient designed an avatar that embodied the annoying hallucination sound.
The therapist uses the voice of the patient.
The suggested sentences, and gradually make the head portrait more friendly, encourage the patient to be more comfortable and confident when speaking.
Dumais\'s team tested 19 patients with mental division in July.
Four people quit after the first meeting because they either didn\'t like the show or felt terrible.
The remaining 15 evaluated the level of horror they found in 0 to 10 VR treatments, 10 of which were the most frustrating.
At the six-week meeting, the score dropped.
In addition, at the end of treatment, the scores of patients on the 0 to 20 scales were calculated from an average of 16 points. 1 to 10. 9.
\"We started very early to simulate the impossible conditions in virtual reality for therapeutic purposes,\" Freeman said . \".
But with the popularity of virtual reality technology, more researchers may have the opportunity to develop creative new therapies that leverage virtual reality technology.
A virtual body can also be used as a therapist to transform virtual reality from a tool that only a clinic can use to a new type of self. help.
This can be particularly useful for patients who are reluctant to see a therapist, such as social anxiety or Plaza phobia, or who live in remote areas without expert help.
The first fully automatic virtual reality treatment was described in August ().

Virtual therapists regularly check how patients feel and provide encouragement.
Freeman and his colleagues tested the program in 100 patients: 49 patients were randomly assigned to two weeks of virtual reality therapy;
51 others were not treated.
One VR participant said: \"I expect this to be like a game, but the project\" broke the limits in terms of what I think I can achieve.
\"On a height fear scale from 16 to 80 years old, the average score of people using VR programs dropped by about 25 points after treatment. The no-

Spiders approach users when virtual therapists provide guidance and encouragement.
\"I\'m not sure if anyone ripped off the headphones, but a lot of people will definitely start crying,\" said Philip Lindner, a clinical psychologist at Philip University.
A patient sat almost in the living room, crawling many spiders on the floor, \"and her legs were actually lifted up and sat like this for 15 minutes.
The results of last November were also described at the Santiago annual Association for Behavioral and Cognitive therapy conference.
Half of the volunteers were randomly assigned to receive VR treatment and were then encouraged to try to approach spiders in the real world.
The other half finished three.
An hour\'s session of normal exposure therapy, participants were working from catching spiders in cups to holding spiders in each hand.
Prior to treatment, the two groups of participants generally did not approach spiders in a clear container, Lindner said.
After treatment, VR participants can stand next to the container and even put their hands into the container
The world\'s exposed patients can touch spiders.
A year later, however, some VR patients can also touch spiders.
Lindner suspects that the virtual reality experience reduces the fear of patients enough for them to try the real experience
The world was exposed by itself, so it caught up with the normal exposure group.

Free virtual reality treatments for more complex diseases can be used at home.
In simulated social interactions, therapists carefully control the response of the virtualized body to address the particular anxiety of each patient. Computer-
Bochard says the generated therapists are not so versatile yet and they can talk to patients in any direction.
However, he does believe that virtual people will eventually reach this level of complexity.
Even if the virtual therapist is up to the job, many patients may not have enough motivation to complete the treatment on their own, Lindner said.

Reger said that treatment was performed separately before they were tested.
These systems may enable many patients who cannot or do not want to see a human therapist to receive treatment, at least for some diseases.
If you can find a safe and effective automated treatment, \"I will definitely be a fan of you, he said.
