What is VR?
"Virtual Reality (VR) is the use of computer technology to create a simulated environment. VR places the user inside an experience. Users are immersed and able to interact with 3D worlds. Simulating senses such as vision, hearing, touch, even smell. Virtual Reality creates an artificial environment to inhabit. The position of the user’s eyes are located within the simulated environment."
Virtual reality technology

Change of research and plan
After a few weeks of researching VR used in medicine and psychological treatment I feel like I don't have a clear path for what I am trying to research and also educate myself on. I feel that because I am not a medical student I do not have enough knowledge to be able to discuss VR used in medicine or surgery. Additionally all the papers I read are coming to the same conclusion which is that it provides the doctors with more visual information. I feel as though that's only the surface and I don't know how to dive in deeper. I am started to become curious about VR used in psychological treatment. Here is a rough plan on what I wish to research and I am hoping that this will guide me:
1. What is Virtual Reality?
2. How are brain works and how we immerse ourselves in stories, films, games, etc.
3. How Virtual reality works on the mind/brain.
4. Mental disorders/ Phobias and treatment
5. Cases of VR being used to treat phobias and examine behaviour/reaction.
This is my rough guideline for myself. I believe that there will be more information on this topic and I'm curious to read how VR works on our mind.

VR in medicine in 1999
Benefits of Virtual reality in medicine.
In this article they made a list of the benefits of Virtual reality in Medicine. Virtual reality is a computer generated simulation of three-dimensional images or environment. One key advantage of using VR instead of a 2D image is that it provides "clinicians with a more naturalistic view of a patient's anatomy." Here are a few other benefits they stated:
- Virtual reality technology plays an important role in telemedicine from remote diagnosis to complex tele interventions.
- Computerized three dimensional atlases of human anatomy, physiology, and pathology are about to revolutionize the teaching of these subjects.
- Several virtual reality systems have been developed and tested for the physical or mental rehabilitation of patients and for supporting mental health therapy.
- Training for medical students.
The technology
"Tactile and haptic (force) sensing is an important source of information when interacting with the virtual environment. Accordingly, these forces have to be transmitted to the user if immersion in a virtual scene with a reasonable level of realism is desired"
Diagnostics
"Virtual endoscopic procedures could replace real endoscopic investigations in the foreseeable future in some areas of diagnosis."
Preoperative planning
"The use of computer models to plan and optimize surgical interventions preoperatively is part of daily clinical practice."
" The planning of a surgery on a computer screen, trying out different surgical approaches with realistic prediction of the outcome (for example, postoperative appearance of the patient), and planning individualised custom made implants have substantial impact on the success and safety of the intervention."
Education and training systems
"Systems based on virtual reality offer a unique opportunity for the training of professional surgical skills."
"The rapid adoption of minimally invasive surgical techniques is one of the major driving forces in the development of surgical trainers. The extreme limitations placed on visual and manipulative freedom, including the loss of tactile feedback and the unusual hand-eye coordination, makes extensive specialised training for such interventions necessary."

My thoughts and conclusion
One important fact that appears in every VR and medicine articles is that VR provides more information for Doctors and Medical students. In this article is talks about using VR to provide a more "natural image" for the Clinicians. We live in a 3D world and Doctors perform surgery on a 3D human. Therefore wouldn't it be easier for doctors to examine 3D images of the areas that are affected?

VR in medicine and psychology
https://www.researchgate.net/profile/Maria_Schultheis/publication/232580487_The_application_of_virtual_reality_technology_in_rehabilitation/links/02e7e517eba3b38088000000.pdf
I found this article on google scholars and it was published in 2001. What's interesting about it is that it talks about VR and how is is still developing but has successfully integrated in multiple areas of medicine and psychology. VR was used in surgical training, treatment of phobias, PTSD and eating disorders. It is also used to distract patients from the pain of dental work, burn treatment and chemotherapy. They state that one "benefit of VR is that it allows users to forget that they are in a simulation".Additionally it provides a safe learning environment that minimizes risks from error.
One of their first "efforts" was creating a virtual classroom and the simulation was aimed at children with ADHD. They created a realistic setting that featured objects that you would normally find in a classroom. They adjusted the simulation based on the age of the child. They monitored the child's "reaction time" to the instruction that they were given in the simulation. "Behavioural factors" such as being distracted and hyperactivity were assessed.
Conclusion
I thought that this article focused more on what exactly AV technology is and how it was used in a way to study patients with mental disorders. It keeps the patient physically safe for them to analyze their behaviour in the simulation. However in this article it questioned the ethics behind it. It might be safe physically for the patient but what about mentally.
